Amanda Demopoulos, Ph.D.
I lead multidisciplinary investigations into coastal and deep-sea benthic communities funded by USGS-EMA and partners, including BOEM and NOAA, that pull together scientists and experts from across USGS, as well as NOAA, BOEM, and many academic institutions. Deep-sea investigations are complex and logistically challenging and require an interdisciplinary approach to disentangle what makes them tick.

Seafloor Benthic Mapping and Characterization: Enhancing our Understanding of Aleutian Islands’ Hazards, Potential Seabed Minerals and Deep Corals
A USGS-led expedition in the Aleutian Arc off Alaska will provide critical information on energy resources, underwater earthquakes and other hazards, seafloor habitats, and biological resources, including key fisheries, as well as potential seabed minerals.

Mesophotic and Deep Benthic Communities: Habitat Assessment and Evaluation
Through a collaborative effort with other federal agencies and academic and research institutions, USGS is working to fill data gaps, determine baseline conditions, and characterize key community conditions at mesophotic and deep benthic sites impacted by the Deepwater Horizon oil spill.
Mesophotic and Deep Benthic Communities: Coral Propagation Technique (CPT) Development Project
Through a collaborative effort with other federal agencies and academic and research institutions, the USGS is working to inform and enhance the protection and management of coral communities in mesophotic and deep benthic areas of the Gulf.
NRDA: Deepwater ROV Sampling to Assess Potential Impacts to Hardbottom Coral Communities and Associates from the Deepwater Horizon Oil Spill
The MC252 oil spill introduced hydrocarbons, dispersants, and drilling muds into the Gulf, potentially adversely affecting the seafloor environment surrounding the spill site.
USGS DISCOVRE: Benthic Ecology, Trophodynamics, and Ecosystem Connectivity – Lophelia II: Continuing Ecological Research on Deep-Sea Corals and Deep Reef Habitats in the Gulf
Deep-sea coral habitats are complex ecosystems at the landscape and local level. While these systems may harbor substantial levels of biodiversity, they remain inadequately investigated.
Connectivity of Coral Ecosystems in the Northwestern Gulf
Connectivity among coral communities influences the probability of speciation and contributes to their ability to adapt to natural and anthropogenic stressors. Results from this study will enhance our understanding of Gulf ecosystems with regional conservation initiatives to inform the restoration of degraded deepwater coral communities and preserve long-term viability of coastal ecosystems.
USGS DISCOVRE: Benthic Ecology, Trophodynamics, Ecosystem Connectivity of Mid-Atlantic Deepwater Hard Bottom Habitats with Emphasis on Canyon and Coral Communities
Deep-sea canyons are complex environments encompassing a range of benthic habitats, including soft sediments along the axis of the canyon, and hard substrates along the canyon walls.
Environmental Impacts following the 1970 Testing of Seabed Mining Equipment on the Blake Plateau- Quantification of Benthic Communities Across Disturbance Gradients
USGS researchers will characterize the ecology of benthic communities associated with deep-sea environments, including hardground features and adjacent soft sediments, and will build upon previous work conducted in areas off the U.S. east coast under consideration for oil and gas leases.
Characterization of Benthic Habitats on the Pacific Margin: Assessing the Connectivity of Hard Substrates, Seeps and Canyon Communities
USGS researchers will characterize the ecology of benthic invertebrates associated with deep-sea environments and broader food-web dynamics within hardground features, seeps, and adjacent soft sediments. This project will provide important information regarding deepwater benthic habitats, such as chemosynthetic communities and deep-sea corals, that could be affected by offshore wind development.
Ecosystems: EXPRESS
The continental shelf and slope offshore California, Oregon, and Washington are home to deep-sea corals, chemosynthetic communities, and other sensitive habitats that could be impacted by the development of energy and mineral resources. The EXPRESS (Expanding Pacific Research and Exploration of Submerged Systems) campaign will map and characterize these special areas to help guide ocean management...
EXPRESS: Expanding Pacific Research and Exploration of Submerged Systems
EXPRESS is a multi-year, multi-institution cooperative research campaign in deep sea areas of California, Oregon, and Washington, including the continental shelf and slope. EXPRESS data and information are intended to guide wise use of living marine resources and habitats, inform ocean energy and mineral resource decisions, and improve offshore hazard assessments.
