# Marine Mammals {#sec-append-mm}

## Introduction

This chapter leverages ongoing data collection and research initiatives related to offshore wind and marine mammals funded by a variety of partners (states, federal agencies, industry).
For an always up-to-date list of active projects, visit the [Offshore Wind & Wildlife Research Database](https://database.rwsc.org/).

Given this ongoing work, the Marine Mammal Subcommittee is making recommendations for additional research that is both aligned with existing efforts and that fills important gaps.

## Focal Marine mammal species and recent trends in the RWSC study area

Marine mammals include baleen whales and toothed whales (together, cetaceans), seals (pinnipeds), and manatees (sirenians).
Distributions of marine mammals have been shifting in response to changes in their environment, including human activities, climate change, and conservation measures.
For a current list of marine mammal species and their status in the RWSC study area, visit the NOAA Fisheries Species Directory at <https://www.fisheries.noaa.gov/species-directory/> and apply filters for "New England/Mid-Atlantic" and "Southeast".

All marine mammal species are protected under the Marine Mammal Protection Act (MMPA) which prohibits intentional or incidental killing, injuring, or harassment of marine mammals and specifies the circumstances and rules under which permits may be issued for such activities.
Under the MMPA, NOAA Fisheries has developed [stock assessment reports](https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-stock-assessments) for all marine mammals in U.S. waters since 1994.
These reports contain estimates of current species population sizes and population trends.
Six marine mammal species are also listed as endangered or threatened under the Endangered Species Act (ESA), which prohibits "take" of these species and requires conservation of their habitat.
In addition to stock assessment reports, NOAA Fisheries generates authoritative and up-to-date information on marine mammal status and trends via the following webpages:

-   [Marine Mammal Unusual Mortality Event](https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-unusual-mortality-events)

-   [NOAA Fisheries Protected Species Surveys](https://www.fisheries.noaa.gov/national/science-data/protected-species-surveys)

-   [Marine Mammal Health and Stranding Response Program](#0) 

Environmental Impact Statements (EISs) associated with the U.S.
National Environmental Policy Act (NEPA) review of offshore wind projects provide detailed descriptions of the affected environment, impact analysis, and cumulative effects.
Each proposed offshore wind project's Final EIS should be considered an important reference for focal marine mammal species, recent trends, habitat considerations, and potential impacts.
Final EISs are posted to BOEM's website.

From a regional and global perspective, natural and anthropogenic climate change are recognized as major drivers of changes in marine mammal distribution, and in some cases, abundance as well [@chavez-rosales2022; @ganley2022; @meyer-gutbrod2022; @pendelton2022; @thorne2022].
Baleen whales' prey in particular-- which include zooplankton and small fish species--are susceptible to ocean warming and changes in ocean circulation.
In response to climate-driven shifts in their prey, baleen whales have shifted foraging locations into places where fewer protections are available [@davies2019], or where conflicts with more human uses are likely.
NOAA's 2023 State of the Ecosystem New England report [@lucey2023] describes the slow movement of several marine mammal species to the northeast and into generally deeper water [@chavez-rosales2022] (and see figure below).

The following data products and tools provide relevant context to inform where new data collection is needed and which research questions are most urgent to address given present status and trends in marine mammal distribution, abundance, behavior as observed in the field or understood by the most recent analyses.
These sources are updated frequently.
Visit the links below for the latest data and information.

[**Habitat-based Marine Mammal Density Models for the U.S. Atlantic:**](https://seamap.env.duke.edu/models/Duke/EC/)The Duke Marine Geospatial Ecology Laboratory leads an ongoing collaboration of federal, state, academic, and independent research organizations who pool scientific data and expertise to develop marine mammal species density models spanning the U.S. east coast and southeast Canada.

[**Passive Acoustic Cetacean Map:**](https://apps-nefsc.fisheries.noaa.gov/pacm/#/) This map shows when and where specific whale, dolphin, and other cetacean species were acoustically detected in the North Atlantic Ocean based on Passive Acoustic Monitoring (PAM).
The dataset was compiled by the NOAA NEFSC Passive Acoustic Research Program using detection data collected by many collaborators.

[**WhaleMap**](https://whalemap.org/WhaleMap/)**:** Designed to communicate the latest whale survey results to scientific, regulatory, and industrial sectors to inform more effective, dynamic planning of research and conservation activities.
The map is synchronized with data repositories from several different survey groups such that results are reported in near-real time.

[**Whale Alert app**](https://www.whalealert.org/)**:** Launched in 2012 as a citizen science tool aimed at reducing the risk of vessel strikes.
The free app uses whale presence data including verified sightings, acoustic detection from buoys and gliders, and aerial surveys to display a user-friendly map based on nautical charts from country-specific government agencies.

**Right Whale Seasonal Management Areas & Dynamic Management Areas (Slow Zones):** Seasonal Management Areas (SMAs) for North Atlantic right whales are zones and times of year when all vessels 65 feet or longer must travel at 10 knots or less to reduce the threat of vessel collisions[^append-mm-1].
Dynamic Management Areas (DMAs) are triggered when groups of whales are sighted outside of active SMAs.
NOAA Fisheries has proposed several modifications to North Atlantic right whale vessel speed regulations which will likely take effect in 2024.
Please check NOAA's website for updated information: <https://www.fisheries.noaa.gov/national/endangered-species-conservation/reducing-vessel-strikes-north-atlantic-right-whales#current-vessel-speed-restrictions>.

**Biologically Important Areas (BIAs) for Cetaceans within U.S. Waters:** BIAs represent areas and times in which cetaceans (whales, dolphins, and porpoises) are known to concentrate for activities related to reproduction, feeding, and migration, as well as the known ranges of small and resident populations [@noaacetsound2015].
Updated descriptions and maps for U.S.
East Coast BIAs are not yet available (as of October 2023) but will be incorporated by reference once they are published [@harrison2023].

**Prey and habitat data:** Marine mammal prey species (e.g., zooplankton, forage fish) are driven by oceanographic factors and in turn drive mammal distribution, abundance, and behavior.
Recent studies of hydrodynamic and oceanographic factors that are impacted by climate change and may also change due to the introduction of offshore wind structures summarize key issues and data gaps:

### Potential effects with respect to offshore wind

As migratory species, many marine mammals' ranges overlap the areas proposed for offshore wind development in the Atlantic Ocean.
In addition, most marine mammal species are exposed to many other types of stressors in these areas.
The cumulative effect of several stressors may create a biologically significant population level response [@kraus2019].

Of the large whale species that are of greatest concern listed in Table 1, baleen whales have typically been prioritized for attention with respect to offshore wind research [@southall2021], due to their distribution and abundance in the study area, behavior, and life history characteristics that make them susceptible to some of the specific stressors potentially associated with offshore wind.
That being said, the majority of studies describing the effects of construction and operation of windfarms on cetaceans come from Europe, where small odontocetes (dolphins and porpoise mainly) are the most common cetaceans.
Avoidance and displacement effects, at ranges up to 10-26 km from the whole footprint of offshore windfarms during construction have been reported [@benhemmalegall2021; @brandt2016; @brandt2018; @dähne2013; @dähne2017; @graham2019; @graham2023].
These studies indicate that the distance and duration of avoidance is related to received noise, which is further influenced by source level, sound propagation conditions, hearing range of the studied species, distance to the noise source, duration of exposure, level and type of mitigation and presence of other noise sources like construction vessels.
There is variation among studies in the time reported for animal behavior to return to pre-construction levels, from hours [@dähne2017] and days [@brandt2018] to years [@teilmann2012], which also suggest that operation of offshore windfarms may also affect cetacean behavior.
Tagging data from Europe around wind energy sites suggest that harbor and grey seals either habituate quickly or may take advantage of the wind farm physical structures as a foraging opportunity [@russell2016].

Kraus et al. 2019 summarized the potential short-term and long-term effects of offshore wind development on marine mammals and sea turtles in Massachusetts and Rhode Island Wind Energy Areas.
The list of potential effects below from this report is relevant to the entire RWSC study area.
Any concerns related to marine mammal species that are specific to each subregion will be further described in the following sections of this chapter.

Overall, climate change increases the uncertainty surrounding marine mammal behavior, distribution and demography, which can abruptly and unexpectedly increases the risks associated with offshore wind development if marine mammals begin to use new areas and habitats or existing habitat more frequently or during different times of year.

**Potential short-term effects of offshore wind construction activities**

Potential short-term effects include noise from pile driving, vessel operating noise, and the increased vessel activity to/from and near turbine fields.
These stressors could influence:

-   Displacement of marine mammals from wind energy areas

-   Increased risk of vessel strike

-   Disruption to critical behaviors of marine mammals such as feeding, socializing, or nursing

-   Elevation of stress hormone levels in marine mammals

-   Changes in vertical distribution, density, or patch structure of zooplankton and/or fish prey

**Potential long-term effects of offshore wind operation**

Potential long-term effects include wind turbine presence, and increased vessel activity to/from and near turbine fields.
These stressors could influence:

-   Marine mammal exclusion from or attraction to wind energy areas

-   Increased risk of vessel strike

-   Changes to feeding opportunities

-   Enhancements to marine productivity due to artificial reef effect around wind turbine foundations

-   Increased risk of entanglement from abandoned, lost, or otherwise discarded fishing gear attached to underwater offshore wind structures

## Recommendations: Marine mammals and offshore wind in the U.S. Atlantic Ocean

This chapter builds on the research topics and questions related to marine mammals and offshore wind proposed by several groups over the last decade that should be addressed by a regional collaborative [@farmer2023; @kershaw2023; @kraus2019; @njrmi2021; @regionalsynthesisworkgroupoftheenvironmentaltechnicalworkinggroup; @southall2021].
The RWSC Marine Mammal Subcommittee considered these previous bodies of work in developing the following list.
In doing so, they have also highlighted the following concepts:

-   Future work will be aligned and coordinated with research needs and actions described in the [BOEM and NOAA Fisheries North Atlantic Right Whale and Offshore Wind Strategy](https://www.boem.gov/sites/default/files/documents/environment/BOEM_NMFS_NARW_OSW.pdf) [@boemnoaafisheries2024].

-   Climate change: Disentangling the impacts to marine mammals from climate change from any potential effects from offshore wind development will be a major challenge.
    For example, any attempt to establish a "baseline" representative of the past several decades must acknowledge that the environment changed rapidly over that time and continues to change rapidly.
    In addition, climate change increases the uncertainty surrounding marine mammal behavior, distribution and demography, which can abruptly and unexpectedly increases the risks associated with offshore wind development if marine mammals begin to use new areas and habitats or existing habitat more frequently or during different times of year.

-   A key contribution of the RWSC Science Plan is the ability to look across all the various data collection activities and identify opportunities for synthesis.

-   Assigning causality to observed changes may not be possible in all studies.

### Data Collection

Several entities are requiring, funding, and/or advocating for marine mammal research and data collection activities with respect to offshore wind.
The Subcommittee strongly recommends that funders ensure that all types of data are collected using consistent methods across locations and projects such that data can be used in other analyses and research, including broad scale analyses of potential impacts across many projects.
Individuals and entities should consult with the Marine Mammal Subcommittee prior to collecting marine mammal data with respect to offshore wind to ensure that any new data collection does not duplicate existing efforts and is consistent with the tools and approaches already in use.
Any individual or entity may join public Marine Mammal Subcommittee meetings by obtaining meeting links on the RWSC website.

A combination of methods (visual, acoustic, tagging) is recommended to provide the most complete information and context to marine mammal observations, given the strengths and limitations of each method alone.
For example, pairing passive acoustics with visual observations can provide more information about marine mammal behavior at the time vocalizations are recorded.

-   Visual observations (ship-based, aerial, conventional imagery) are most robust during daylight hours and weather conditions with good visibility.
    However, these methods only capture marine mammals at or near the surface.

-   Thermal and infrared imagery increases the amount of time each day that marine mammals can be detected visually.
    Some of the technologies associated with imagery are being tested by offshore wind developers and other experts.

-   Passive acoustics (real-time and archival) can be used to detect marine mammals during all hours of the day, all year long, and during most conditions (high levels of ambient noise could impact detection).
    However, acoustics tools only detect whales that are vocalizing.

-   Tagging methods are typically applied to understand fine-scale movement and behavior of individuals.
    Tags may be difficult to deploy but can provide useful information about an animal's responses to oceanographic conditions or known stressors that are being measured simultaneously.

BOEM requires various types of marine mammal data collection and monitoring as part of the approval process for each offshore wind project's Construction and Operations Plans (COPs).
These activities may include:

-   Visual and passive acoustic monitoring of vessel transit corridors to/from the project site

-   Passive acoustic monitoring and visual surveys before and during activities such as pile driving and geophysical surveys

-   Long-term/archival passive acoustic monitoring to record ambient noise and marine mammal species before, during, and for a specified period of time after construction

NOAA, BOEM, and several states are also funding the deployment of passive acoustic monitoring sensors in the RWSC study area.
Deployment locations and [data management](https://rwscollab.github.io/pam-data-mgmt/) are being coordinated through the RWSC Marine Mammal Subcommittee (visit <https://rwsc.org/pam> for the latest information).
The recently completed [*Power analysis for optimal design of a passive acoustic monitoring network for US east coast offshore wind*](https://espis.boem.gov/final%20reports/BOEM_2023-041.pdf) [@chudzinska2023] highlighted several data gaps that if filled, would improve the ability to assess the statistical power of the regional passive acoustic monitoring network:

-   Improve estimates of acoustic detection rates and cue rates of baleen whales during non-construction conditions.

-   Improve dose-response curves by obtaining in-situ behavioral data at offshore wind construction sites on baleen whale responses to pile driving noise.
    This would require collecting a range of data types including PAM and visual observations (aerial or ship-based).

-   Expand passive acoustic monitoring outside of wind energy areas, especially along the shelf break, including using gliders and real-time systems.

Additional recommendations for the implementation of a regional scale passive acoustic monitoring network include:

-   Characterize baseline ambient sound and sound/noise during all phases of development, leveraging the regional passive acoustic monitoring network.

-   Expand passive acoustic monitoring outside of wind energy areas, especially along the shelf break, including using gliders and real-time systems.

-   To the extent practicable, ensure alignment between archival and real-time deployments.
    Ensure that whale detection from real-time systems can be folded into analyses and data products that also leverage archival detection.

-   Couple aerial/visual monitoring with acoustic monitoring to address the issues above and better link the resulting observational datasets.

-   Co-deploy acoustic telemetry receivers to build out a telemetry receiver network, and other sensors as practicable.

The Subcommittee recommends the following regional-scale data collection efforts:

-   (Cross taxa) Leveraging BOEM and NOAA's ongoing efforts, ensure that the required Protected Species Observer data collected by offshore wind companies during construction and operations via Pile Driving Monitoring Plans and Vessel Strike Avoidance Plans (and any other mitigation plans) follows a consistent reporting approach and is eventually submitted to a Master Protected Species Observer Sightings Database for use in marine mammal analyses and research.

-   Ensure that other marine mammal and environmental data collection required by the agencies during installation (e.g., sound fields, visual monitoring, PAM, thermal/infrared camera systems) are collected using consistent methods such that data can be used in other analyses and research including broader scale analyses of potential impacts across many projects.

-   (Cross-taxa) Continue regional scale protected species and habitat data collection activities through the [Atlantic Marine Assessment Program for Protected Species](https://www.fisheries.noaa.gov/new-england-mid-atlantic/population-assessments/atlantic-marine-assessment-program-protected) (AMAPPS), [Ecosystem Monitoring Survey](https://www.fisheries.noaa.gov/feature-story/monitoring-northeast-shelf-ecosystem); [NOAA Fisheries North Atlantic Right Whale Aerial Surveys](https://www.fisheries.noaa.gov/resource/document/north-atlantic-right-whale-sighting-survey-reports), NOAA Fisheries Marine Mammal and Sea Turtle Aerial Surveys, NOAA Fisheries Marine Mammal, Sea Turtle, and Seabird ship-based surveys; NOAA Fisheries Seal aerial abundance surveys.
    Advance the NOAA Fisheries and BOEM Survey Mitigation Strategy [@hare2022] to ensure that site-specific and regional scale studies are put in the context of population trends and ecosystem conditions.

-   (Cross-taxa) Coordinate regular high-definition aerial surveys that cover multiple lease areas using the same tools and methods.
    This effort should leverage the considerable amount of high-definition aerial photography data collected during site assessment by multiple offshore wind developers, and the [Southern New England megafauna aerial surveys](https://www.masscec.com/resources/marine-mammal-and-sea-turtle-surveys) that have occurred consistently since 2011.

-   Collect marine mammal behavioral and health data through tagging and visual observations to determine how individuals interact with wind farm structures and whether changes to foraging, socializing, or reproduction are occurring.

-   In collaboration with NOAA Fisheries, continue and expand stranding data collection and analysis with respect to stranding and mortality data time series analysis for the U.S.
    Atlantic Ocean.

-   Monitor entanglement with subsea structure of floating offshore wind structures and monitor secondary entanglement where derelict fishing gear/marine debris may attach to subsurface offshore wind structures.

-   Coordinate with the Northeastern Regional Association of Coastal and Ocean Observing Systems (NERACOOS), Mid-Atlantic Regional Association of Coastal Ocean Observing Systems (MARACOOS), and Southeastern Coastal Ocean Observing Regional Association (SECOORA) to advance oceanographic and biological data collection and use in marine mammal research.

-   Leverage existing ocean observing platforms or add new ocean observing assets for marine mammal monitoring.

-   Work with the Habitat & Ecosystem Subcommittee to ensure that key oceanographic and habitat data are collected and available as data products for use in marine mammal studies and as model covariates.

-   Work with the Habitat & Ecosystem Subcommittee to determine whether offshore wind structures alter hydrodynamics, stratification, and mixing, and/or prey distribution and abundance.

-   Continue to collect data across the region that allows analysis and synthesis of prey fields.
    Develop a coordinated regional scale zooplankton monitoring and mapping effort that builds off of and links existing surveys and studies including EcoMon, Continuous Plankton Recorder, the Gulf of Maine MBON, BOEM-funded Zooplankton Ecology study, Canadian AZMP, Center for Coastal Studies, Northeast U.S. Shelf LTER, and projects conducted by Stony Brook University and Rutgers University to establish a broader ecosystem observing system, synthesize patterns, and identify trends and linkages across trophic levels.

There is a need to advance technologies that improve marine mammal detection during all phases of offshore wind development, and to ensure that the performance of new technologies is evaluated consistently (see Technology chapter recommendations): @sec-technology

-   Develop, evaluate performance, and apply existing and emerging technologies that enhance marine mammal detection, including thermal cameras, infrared cameras, passive acoustics systems, and systems that integrate multiple methods for use during construction and operational monitoring and mitigation.
    Test "smart" mitigation methods triggered by marine mammal presence as determined by these systems.

-   Advance quieting technologies meant to mitigate construction noise (pile driving, vessel traffic) and operational noise (vessel traffic, operational vibratory sound).

-   Develop and deploy safe long-duration satellite tagging telemetry technology for tracking high-resolution movements of marine mammals in and around offshore wind structures.

-   Improve analysis of monitoring data through artificial intelligence, automated acoustic, and image processing, and near real-time data availability.

-   (Cross taxa) Develop and test eDNA assays/surveys/sampling regimes to understand efficacy of use developing indices of occurrence/abundance, including testing the effect of carcasses in the environment on eDNA detection.

View ongoing and planned data collection activities for marine mammals in each subregion of the RWSC study area in the [RWSC Offshore Wind and Wildlife Research Database](https://database.rwsc.org/).
Based on those activities, plans for new data collection should consider the following:

The **Gulf of Maine** has long represented important feeding grounds for baleen whales from late fall to early spring.
A resident population of Harbor porpoise is present in the coastal/nearshore areas of the Gulf of Maine from July to September.
Almost all of the Gulf of Maine subregion is critical habitat (Northeastern U.S. foraging area) for North Atlantic right whales.
Given that offshore wind development areas are still being identified in this subregion, baseline data collection should seek to characterize fine scale spatial and temporal habitat use.
Studies of impacts specific to floating offshore wind (e.g., secondary entanglement), including modeling, should be coordinated through the Subcommittee.
Cape Cod Bay, as a historical whale aggregation location, could serve as a sentinel site or control site to monitor potential population-level impacts to whales.

In **Southern New England**, known whale foraging hotspots (e.g., Nantucket Shoals) should be monitored using multiple methods to understand potential changes in behavior and habitat use.
Studies of hydrodynamics and physical oceanography at the turbine- and wind farm-scales should seek to disentangle climate change drivers from offshore wind development and understand any changes that may impact whale prey [@acp2023].

Whale and dolphin sightings in the **NY/NJ Bight** have increased recently and includes increases in juvenile humpback whales in coastal waters, likely due to an increase in their menhaden prey.
These whales may be particularly vulnerable to vessel strike due to their behavior and high density and speed of vessels in nearshore waters of this region [@stepanuk2021].
Studies of whale-prey relationships and potential displacement from offshore wind areas in this region should be tailored to this context and capture rapidly changing ecosystem conditions and existing human uses in this area.

The **U.S. Central Atlantic** includes small resident populations of bottlenose dolphins, and large whales occur here and in the **U.S. Southeast Atlantic** at relatively lower densities than the other subregions.
Data collection strategies and studies should be designed with the lower expected densities in mind.
Both regions are important migratory routes, and the U.S.
Southeast Atlantic contains critical habitat for North Atlantic right whale calving.
Pregnant and nursing North Atlantic right whales and their calves are particularly vulnerable to vessel strikes in the Southeast U.S. from November to April annually because of the shallow bathymetry, the whales' tendency to float at or just below the surface, and their long residency times in Southeast U.S. waters (approximately 2 months) [@cusano2019; @gowan2014; @krzystanam2018].
Calving females and their calves may also be at greater risk of exposure to acoustic impacts because of their long residency times [@krzystanam2018].
More information is needed about the ways that reproductively active female right whales respond (or do not respond) to physical structures, noise, and vessels in their environment before wind projects are implemented in the Southeast right whale calving habitat.
Characterizations of marine mammal distribution, abundance, and movement should continue in these subregions using multiple methods as offshore wind planning and development advances.

### Data Analysis

Data analyses should inform where new data collection is needed, characterize oceanographic and habitat drivers of marine mammal distribution, abundance, and behavior, seek to assess whether offshore wind is causing any observed changes, and evaluate the efficacy of monitoring and mitigation strategies.
The Subcommittee is especially interested in studies that seek to distinguish between climate change-driven shifts in marine mammal distribution, abundance, and behavior and changes that may be driven by offshore wind construction and operation.
Related changes of interest include:

-   Whether construction activities displace or attract marine mammals

-   Whether offshore wind structures displace or attract marine mammals

-   Whether marine mammal feeding is altered due to changes to hydrodynamics or prey distribution/abundances caused by offshore wind structures

Individuals and entities should consult with the Marine Mammal Subcommittee prior to conducting analyses of marine mammal data with respect to offshore wind to ensure that the study leverages all of the available data and contributes to addressing the key recommendations described below to the extent possible.

**In particular, researchers are strongly encouraged to leverage extensive existing and long-term data sources.** These include but are not limited to AMAPPS, NOAA Fisheries North Atlantic Right Whale Aerial Surveys, Southern New England Aerial Megafauna Surveys, long-term/archival PAM, as well as shorter-duration observational studies (aerial, boat-based, tagging) as foundational elements of any analysis.

The following types of analyses are recommended:

-   **Conduct a synthetic baseline assessment of marine mammals over the past several decades to characterize pre-development levels of spatial and temporal variability in marine mammal distribution and abundance patterns, from which to measure and assess any potential changes after the onset of offshore wind construction and regional-scale operation activities.** Integrate density modeling and/or visual survey data, passive acoustic monitoring data, tagging data, oceanography/habitat data, and climate data to characterize pre-development levels of spatial and temporal variability in marine mammal distribution and abundance patterns.

-   **Continue to update and improve marine mammal density models.** Use outputs to understand drivers of marine mammal distribution and movement and to assess/detect change, displacement, and/or potential impacts.
    Periodically evaluate model performance and use validation and evaluation results to continually inform and advance model/framework development and applications.

    -   Integrate the latest observational and environmental data every 2-3 years.

    -   Integrate data from multiple additional methods (strandings, digital aerial surveys, passive acoustic data, tagging) and covariates (oceanographic and prey distribution).
        Apply results to inform research designs, determine baseline abundance/distribution estimates, best practices, etc.

    -   Consider how to structure future model "eras" to reflect offshore wind pre-construction and construction/operation.

    -   The modeling framework should be scalable to individual projects and the whole region such that individual project-specific outputs could be pooled into regional-scale versions of the model.

-   **Repeat a power analysis to optimize the design of the long-term archival passive acoustic monitoring network every 3-5 years.** Ensure that new monitoring assets and analysis results are accounted for and that existing or new hypotheses and questions can be addressed by the regional network.

-   **Inform and evaluate the effectiveness of mitigation strategies meant to minimize impacts resulting from increases in vessel traffic (i.e., noise, collision, displacement) from construction and maintenance of offshore wind projects.**

    -   Develop or update existing vessel and marine mammal co-occurrence models with information from the offshore wind industry regarding vessel types and numbers.
        Validate models with AIS and effort-corrected whale sightings data.

    -   Conduct studies to assess the effectiveness of mitigation strategies such as speed restrictions, establishment of traffic corridors, etc.

-   **Model and assess entanglement risks associated with floating offshore wind.**

-   **Build off [Project WOW](https://offshorewind.env.duke.edu/) and apply lessons learned to studies in and around other lease areas outside Southern New England and NY/NJ Bight.** Use Project WOW Frameworks to identify stressors, species, and geographic areas to conduct assessments of displacement, attraction, or other changes to wildlife abundance, distribution, behavior, and/or health.

-   **Integrate multiple types of data (e.g., acoustic, visual, stable isotopes, bycatch estimates, vessel trip reports) to understand potential changes in marine mammal feeding behaviors.**

-   **Determine whether prey distribution, abundance and/or behavior is altered due to hydrodynamic changes caused by offshore wind structures and from EMF/cables (heat and electromagnetic field).**

-   **Scope studies of EMF and marine mammals.** Include studies of whether animals can detect EMF, what the sensing capabilities are, and over what distance.

### Data Management

Understanding marine mammal movement and behavior near offshore wind developments will require close coordination among researchers, state and federal agencies, and industry. 
The Marine Mammal Subcommittee will work with individuals and entities who conduct marine mammals and offshore wind monitoring and research to ensure that data are collected and stored in consistent formats that allow comparisons and pooling across individual projects in the RWSC study area. 
This standardization is intended to support regional-scale assessments and the development and maintenance of regional data products and tools (e.g., marine mammal density models).

To support these efforts, the Marine Mammal Subcommittee recommends: 

-   Maintenance of an up-to-date resource list of recommended repositories, data and metadata standards, guidance, and protocols for use by all data collectors. 
    The current recommended resources are detailed in the table below. 

-   Development of standard language for inclusion in requests for proposals and funding agreements to encourage or require the use of recommended resources. 

-   Establishment of data sharing frameworks to appropriately manage access to sensitive industry-collected datasets necessary for research (e.g., acoustic data, Protected Species Observer data).

-   Collaboratively establish timelines for marine mammal detection data upload and dissemination, especially through public platforms and apps, e.g., WhaleAlert, WhaleMap.

The following table lists the repositories and standards that are recommended for use in marine mammal data collection and identifies data types for which no or limited data management capacity (i.e., standard repositories and guidance) currently exists.
