In contrast to other oligotrophic water bodies the Gulf of Mexico (GOM) hosts an abundance of hydrocarbon seeps, which likely influences the microbial assemblages it hosts particularly regarding the availability of labile carbon in the aphotic GOM. The aphotic zone receives direct injection of seep methane (CH4), but CH4 from an unknown source has been reported at supersaturated concentrations ...

Quantitative collections of tubewormand mussel-associated communities were obtained from 3 cold seep sites in the deep Gulf of Mexico: in Atwater Valley at 1890m depth, in Alaminos Canyon at 2200m depth, and from the Florida Escarpment at 3300m depth. A total of 50 taxa of macroand megafauna were collected including 2 species of siboglinid tubeworms and 3 species of bathymodiolin mussels. In ge...

BACKGROUND Vestimentiferan tubeworms are some of the most recognizable fauna found at deep-sea cold seeps, isolated environments where hydrocarbon rich fluids fuel biological communities. Several studies have investigated tubeworm population structure; however, much is still unknown about larval dispersal patterns at Gulf of Mexico (GoM) seeps. As such, researchers have applied microsatellite m...

In marine sediments the anaerobic oxidation of methane with sulfate as electron acceptor (AOM) is responsible for the removal of a major part of the greenhouse gas methane. AOM is performed by consortia of anaerobic methane-oxidizing archaea (ANME) and their specific partner bacteria. The physiology of these organisms is poorly understood, which is due to their slow growth with doubling times i...

r a 200 .007 : +1 302 del.edu Summary The contributions of hillslope and riparian sources of runoff to streamflow were determined for four catchments (1.6–696 ha) in the Point Peter Brook watershed, a glaciated, forested, watershed in Western New York, USA. Investigations were performed for 10 storm events of varying size, intensity, and antecedent moisture conditions. Hydrometric, geochemical,...

The Gulf of Mexico is a hydrocarbon-rich region characterized by the presence floating oil slicks from persistent natural hydrocarbon seeps, which are reliably captured synthetic aperture radar (SAR) satellite imaging. Improving state knowledge seepage in improves understanding and quantification rates North America. We used data derived SAR scenes collected over 1978 to 2018 locate slick origi...
