PDF Effects of Ocean Acidification and Sea-Level Rise on Coral Reefs [More info]
By measuring the current and historical growth rates of coral skeletons, and using field experiments, we intend to find out whether rising atmospheric CO2 and rising sea levels will cause coral reefs to erode and cease to function.
PDF Fine-grained sediment dispersal along the California coast [More info]
Fine-grained material may negative effects on coastal ecosystems. Our studies suggest that the waves and currents of California are adequately energetic to transport fine-grained sediment quickly through near-shore coastal systems.
PDF Gulf of Mexico deep-sea coral ecosystem studies, 2008-2011 [More info]
Deep-sea corals, also known as cold-water corals, have become a topic of interest due to conservation concerns over the impacts of trawling, exploration for oil and gas, and climate change.
Hypoxia [More info]
A brief definition and explanation of hypoxia with special reference to the Gulf of Mexico hypoxic zone along the Louisiana-Texas coast as well as extensive links to USGS and other related information resources.
Hypoxia in the Gulf of Mexico and related USGS activities [More info]
Information about the causes and impact of hypoxia with links to USGS and other Federal agency information and activities related to nutrients in the Mississippi River Basin and hypoxia in the Gulf of Mexico.
PDF Invasive lionfish use a diversity of habitats in Florida [More info]
Describes the diversity of habitat types in which invasive lionfish have been reported within Florida's coastal waters, based on lionfish sightings recored in our Nonindigenous Aquatic Species database.
PDF Investigación del USGS sobre el ecosistema de arrecifes de coral en el Atlántico [More info]
Los arrecifes de coral son estructuras sólidas, biomineralizadas que protegen comunidades costeras actuando como barreras protectoras de peligros tales como los huracanes y los tsunamis.
PDF Microbial ecology of deep-water mid-Atlantic canyons [More info]
Plan for an upcoming study, at the microbiological scale, of the benthic communities (including corals) that reside in and around mid-Atlantic canyons, which are located at the edge of the continental shelf.
Oculina Bank - geology of a deep-water coral reef habitat off Florida [More info]
Brief report on sidescan sonar data, sediment sampling, and submersible and video photography studies of destruction of deep-water coral pinnacles where fish spawn off east-central Florida in the Oculina Bank in order to restore and protect the habitat.
Pacific Walrus Response to Arctic Sea Ice Losses [More info]
Radio-tracking indicates that walruses will exploit sparse ice to maintain access to preferred foraging areas over the continental shelf.
