In 1972, at a location in the eastern equatorial Pacific ~ 200 miles northeast of the Galápagos Islands, a young graduate student researcher was using surplus US Navy sonobuoys to listen to the portio...
Hydrothermal vents are among the most biologically active regions of the deep ocean. However, our understanding of the limits of life in this extreme environment, the extent of biogeochemical transfor...
Diffuse-flow, low-temperature areas near hydrothermal vents support life via chemosynthesis: hydrogen sulfide (and other reduced chemical compounds) emanating from the subsurface is oxidized with bott...
Tectonic and volcanic processes that drive hydrothermal fluid flow and influence its chemistry also regulate the transfer of energy to hydrothermal vent ecosystems. Chemoautotrophic bacteria use the c...
Black smokers are the dramatic result of seawater being heated to high temperatures (generally 250° to 350°C) by magmatic systems, then discharging at the seafloor. However, not all seawater that circ...
This dissertation research aims to show that there are deterministic microbial distribution patterns based on quantifiable environmental thresholds by determining and rationalizing the relative abunda...
ANN ARBOR—More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.
The concentrations and distributions of dissolved free amino acids (DFAA) were determined in 31 hydrothermal fluid samples from the Logatchev field at 15°N and several hydrothermal vent fields between...
Scientists at Columbia’s Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn m...
Variation in larval supply to disjunct marine populations can provide insight into larval transport and delivery mechanisms, especially when compared with observations of physical transport. Daily va...
April 18, 2007,A new "black smoker"--an undersea mineral chimney emitting hot springs of iron-darkened water--has been discovered at 8,500-foot depths by an expedition funded by the National Science F...
Hydrothermal systems of deep-sea spreading centers stand out as islands of life on a seafloor where the abundance of megafauna is otherwise very low. These hydrothermal systems support a dense biomass...
Larval supply in marine benthic invertebrates influences patterns of settlement and recruitment to adult populations. To successfully colonize newly formed or distant hydrothermal vents, which are dis...
Samples collected in low-temperature (2–508 C) waters near hydrothermal vents of the Southern Explorer Ridge, in the northeast Pacific Ocean, contained fine ( ,500 nm) Fe-and Mn-oxide and Fe-silicate ...
