Journal ArticleDOI
Quantifying fluid flow, solute mixing and biogeochemical turnover at cold vents of the eastern Aleutian subduction zone
Klaus Wallmann,Peter Linke,Erwin Suess,Gerhard Bohrmann,Heiko Sahling,Michael Schlüter,A. Dählmann,Stephan Lammers,Jens Greinert,Nikolaus von Mirbach +9 more
TL;DR: In situ oxygen fluxes were measured at vent sites in the Aleutian trench at a water depth of almost 5000 m using a TV-guided benthic flux chamber.
Journal ArticleDOI
Fluid venting in the eastern Aleutian Subduction Zone
Erwin Suess,Gerhard Bohrmann,Roland von Huene,Peter Linke,Klaus Wallmann,Stephan Lammers,Heiko Sahling,Gisela Winckler,Richard A. Lutz,Daniel L. Orange +9 more
TL;DR: A biogeochemical approach toward estimating fluid flow rates from individual vents based on oxygen flux measurements and vent fluid analysis indicates a mean value of 5.5 + 0.7 L m -2 d -1 for tectonics-induced water flow as discussed by the authors.
Journal ArticleDOI
A large methane plume east of Bear Island (Barents Sea): Implications for the marine methane cycle
TL;DR: In this paper, a pockmark field extending over 35 km2 at 74°54′N, 27°3′E, described by Solheim and Elverhoi (1993), was re-surveyed and found to be covered with more than 30 steep-sided craters between 300 and 700 m in diameter and up to 28 m deep.
Journal ArticleDOI
An improved head-space analysis method for methane in seawater
Stephan Lammers,Erwin Suess +1 more
TL;DR: A widely used degassing method for methane in seawater employing vacuum was tested and subsequently improved as discussed by the authors, yielding 62 ± 3.8% of the total dissolved methane, hence a reproducible correction factor was established.
Journal ArticleDOI
Hydrothermal activity at Hook Ridge in the Central Bransfield Basin, Antarctica
Gerhard Bohrmann,C. Chin,Sven Petersen,Heiko Sahling,Ulrich Schwarz-Schampera,Jens Greinert,Stephan Lammers,Gregor Rehder,A. Daehlmann,Klaus Wallmann,S. Dijkstra,Hans-Werner Schenke +11 more
TL;DR: In this article, an active low-temperature vent field on top of a submarine volcanic structure was detected and the sea floor showed various patches of white silica (opal-A) precipitate exposures and some yellow-brown Fe-oxyhydroxide crusts.
