Whence comes the name “Escanaba”?
As the Escanaba Trough expedition wraps up, there remains one somewhat prosaic mystery: Why do we call this seafloor spreading center Escanaba Trough?

Deep Sea Exploration, Mapping and Characterization
Deep sea areas support unique ecosystems and are sources for energy and minerals. Exploring and mapping the oceans will help us fill gaps to better understand planetary-scale processes including tectonics and marine hazards; energy, mineral and biological resources; and other large-scale Earth systems. Improved knowledge of the deep sea will help us sustainably manage and use ocean resources.

Realizing the potential of eDNA biodiversity monitoring tools in the marine environment with application to offshore renewable energy
The U.S. Geological Survey (USGS) researches the biological diversity and distribution of species to support management, conservation, and resource use decisions. USGS scientists advance detection and monitoring technologies to assess changes in fish and wildlife populations, biodiversity, and the health of ecosystems. The United States is planning to install 30 gigawatts of offshore...

Systematic mapping of the ocean-continent transform plate boundary of the Queen Charlotte fault system, southeastern Alaska and western British Columbia—A preliminary bathymetric terrain model
In 2015, U.S. Geological Survey scientists in collaboration with scientists from other institutions began a study of the Queen Charlotte fault—the first systematic study of the fault in more than three decades. The primary goal of the study was to gain a better understanding of the earthquake, tsunami, and underwater-landslide hazards throughout southeastern Alaska, as well as gather...
Categorizing active marine acoustic sources based on their potential to affect marine animals
Marine acoustic sources are widely used for geophysical imaging, oceanographic sensing, and communicating with and tracking objects or robotic vehicles in the water column. Under the U.S. Marine Mammal Protection Act and similar regulations in several other countries, the impact of controlled acoustic sources is assessed based on whether the sound levels received by marine mammals meet...

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.
