I lead the USGS DEEP SEARCH Project, jointly funded by the Environments Program, BOEM, and the NOAA-Office of Ocean Exploration and Research. Scientists involved in the project stem from 5 USGS science centers, academic institutions, and NOAA. Complex deep-sea environments, including corals, sponges, and chemosynthetic systems require interdisciplinary science to untangle what makes them tick.
EDUCATION
Ph.D., Biological Oceanography, Department of Oceanography, UH Manoa, August 2004
M.S., Biological Oceanography, Department of Oceanography, UH Manoa, December 2000
B.S., Oceanography-Biological emphasis (Minor: Chemistry), College of Oceanography, University of Washington, June 1996
RESEARCH
My research program spans from coastal wetlands to deep-sea environments, where I examine benthic invertebrate community structure and function, including food webs, and impacts of natural and anthropogenic disturbance on benthic ecosystem health.

Connectivity of Tropical Marine Ecosystems: Understanding Biodiversity and Trophic Relationships in the Virgin Islands and Puerto Rico
Marine reserves and protected areas in the U.S. Virgin Islands and Puerto Rico encompass a variety of tropical ecosystems, including coral reefs, mangroves, and seagrass beds, but questions remain regarding how effective these areas are at preserving and protecting the habitats and species they encompass. USGS and collaborators address this question by examining the biodiversity and food web...
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 of Mexico, 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 of Mexico
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.
Exploration of Caribbean Seamounts within the Greater and Lesser Antilles (GA/LA) Transition Zone: Characterization of the Benthic Ecology and Geology
Seamounts may be biodiversity hotspots, oases, islands, and centers for endemism in the deep sea. USGS and partners explore these possibilities within the Greater and Lesser Antilles Transition Zone.
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.
Connectivity of Coral Ecosystems in the Northwestern Gulf of Mexico
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 of Mexcio ecosystems with regional conservation initiatives to inform the restoration of degraded deepwater coral communities and preserve long-term viability of coastal...
Seeking the Seeps
From June 12 to July 3, 2019, the USGS sailed onboard Schmidt Ocean Institute’s R/V Falkor with several other partners, seeking methane seeps along the seafloor of several underwater canyons off the coast of Oregon and Washington. On this cruise, USGS scientists will seek to understand how much methane is coming out of these seeps, how it travels through the water column, and its ultimate fate in...

Evaluating Structural and Surface Elevation Recovery of Restored Mangroves
Hydrologic restoration is one of several approaches to rehabilitate mangroves on a large-scale. USGS evaluates how solely restoring tidal hydrologic flows affect the recovery of mangroves in Florida.
DISCOVRE: Diversity, Systematics and Connectivity of Vulnerable Reef Ecosystems
DISCOVRE (DIversity, Systematics and COnnectivity of Vulnerable Reef Ecosystems) is an integrated, multidisciplinary, international effort investigating the unique and fragile deep-sea coral environments from the microscopic level to the ecosystem level.
IMMeRSS-- Interagency Mission for Methane Research on Seafloor Seeps
From May 3 to May 11, 2017, the U.S. Geological Survey, in collaboration with the British Geological Survey and with support from these two agencies, the National Oceanic and Atmospheric Administration (NOAA) Office of Ocean Exploration and Research, and the U.S. Department of Energy, will lead an expedition aboard the R/V Hugh R. Sharp to explore seafloor methane seeps on the northern U.S...
IMMeRSS- Seafloor Methane Seep Environments
Cold seeps, which are locations where chemicals -- including methane and other hydrocarbons, brine, hydrogen sulfide, and sometimes carbon dioxide--leak from the seafloor, occur worldwide on both passive and tectonically-active continental margins. Cold seeps are distinguished from hydrothermal vents, which are warm-temperature seeps associated with mid-ocean spreading centers.
USGS Role in DEEP SEARCH: Deep Sea Exploration to Advance Research on Coral, Canyon, and Cold-seep Habitats
USGS scientists are collaborating with multiple agencies to provide the esssential foundation for understanding these deep-sea environments.
