BOEM develops, conducts and oversees world-class scientific research to inform its policy decisions. By using science, regulatory frameworks and input from others, the bureau considers the potential for BOEM activities to impact the ocean’s physical characteristics, biological resources and marine or coastal uses that are important to the environment and society.

In 2021, Secretary Haaland charged the U.S. Geological Survey to “Unleash the Science” to ensure that science and research is being shared to “help all of us make the best decisions for our planet now and for the future.” Over the past three years, bureaus across the Department, including BOEM, have continued to meet this challenge -- both investing in science and applying it to guide evidence-based decision making.

BOEM-Sponsored Saildrone Surveyor Expedition Returning Home After Exploring Aleutian Islands

Since departing Dutch Harbor on August 11, the uncrewed surface vehicle (USV) Saildrone Surveyor has been collecting seafloor mapping and surface oceanographic data in priority areas of the relatively unexplored Aleutian Islands. The expedition, part of a multi-agency public-private partnership funded by the Bureau of Ocean Energy Management (BOEM) and the National Oceanic and Atmospheric Administration (NOAA), gathered data on several large, unexplored areas off the Aleutian chain identified as high priority for NOAA, BOEM, the U.S. Geological Survey, and the broader federal Interagency Working Group on Ocean Exploration and Characterization.

Pursuing New Frontiers in Ocean Exploration and Characterization

The U.S. Ocean Policy Committee recently released the report Strategic Priorities for Ocean Exploration and Characterization of the United States Exclusive Economic Zone. The report identifies current high-priority geographies and thematic topics that require better characterization and understanding. Federal agencies working to address these priorities will help advance the nation’s forecasting of seafloor hazards, improve understanding of ocean cultural heritage and uncover important new knowledge about previously underexplored habitats and ecosystems. As a co-chair of the Working Group and a Council member agency, BOEM played an integral role in the report’s development and is actively promoting interagency efforts to further meet ocean exploration and characterization needs.

Discovering Lost Worlds

The ocean contains archaeological remains from every age of human history, and the BOEM Marine Archaeology program is responsible for studying and cataloging pre-contact human settlement and deep-sea shipwrecks. These finds have the potential to contribute significantly to our understanding of the commerce, technology, and culture of bygone eras, as well as inform agency decision-making on energy development.

BOEM Funds Study to Improve EPA Air Quality Model for Overwater Applications

Working under an interagency agreement with the Environmental Protection Agency (EPA), BOEM recently funded an effort to update and improve coding for the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD), a dispersion modeling system that uses meteorological data, including wind speed and direction, temperature and turbulence, plus emissions data, to predict air quality impacts. Updating the program’s platform downwash algorithm will result in more accurate model results, improving BOEM’s offshore activity impact assessments and better informing the bureau’s policy decisions.

Sei whales are an endangered species of special interest to the Bureau of Ocean Energy Management and National Oceanic and Atmospheric Administration (NOAA)

BOEM and NOAA Complete First-Ever Successful Drone-based Tagging of Endangered Sei Whales in U.S.

BOEM and the National Oceanic and Atmospheric Administration’s (NOAA) Stellwagen Bank National Marine Sanctuary have completed the digital acoustic tagging of 14 sei whales in waters offshore Massachusetts – the first time researchers have successfully tagged an endangered species in the United States using an uncrewed aerial vehicle (UAV), or drone. The collected data will shed important light on the whales’ acoustic behavior, which researchers will use to inform mitigation strategies – including passive acoustic monitoring – to protect this endangered species from the potential impacts of offshore wind energy activities.

BOEM Partners with Louisiana High School to Monitor Air Quality Study Station

Environmental oversight in the Gulf of Mexico is an essential part of BOEM’s mission, and the collection of air quality and weather data near areas where offshore oil and gas activities are taking place is an important aspect of this effort. This data helps scientists assess the impact of pollutants from offshore development on regional air quality.

How Loud is Too Loud?

Protecting the environment while ensuring the safe development of offshore energy is a critical part of BOEM’s mission. Sea turtles are endangered species and a sentinel species for the effects of climate change. Loud underwater activities, such as seismic surveys or pile driving for renewable energy installations, could be harmful to these protected animals. BOEM wants to understand how the activities it permits impact these species so it can make informed, science-based decisions. Consequently, the bureau is collaborating with the National Oceanic and Atmospheric Administration, North Carolina State and Duke Universities in the U.S. and with sea turtle researchers in Dominica to measure sea turtle hearing to help fill in data gaps about the species’ hearing sensitivity.

Will Crabs Cross Undersea Cables?

Commercial fishermen have expressed concern about the potential impacts electromagnetic fields associated with offshore energy development could have on crabs. BOEM partnered with researchers and fishermen to conduct a four-month study to help the bureau better understand whether offshore energy-related undersea cables effect crab behavior. The study is part of BOEM’s larger efforts to ensure that offshore energy and commercial fisheries can successfully co-exist.
