Abstract. First videographic indication of an Antarctic cold seep ecosystem was recently obtained from the collapsed Larsen B ice shelf, western Weddell Sea (Domack et al., 2005). Within the framework of the R/V Polarstern expedition ANTXXIII-8, we revisited this area for geochemical, microbiological and further videographical examinations. During two dives with ROV Cherokee (MARUM, Bremen), several bivalve shell agglomerations of the seep-associated, chemosynthetic clam Calyptogena sp. were… Expand

Characterisation of the Nematode Community of a Low-Activity Cold Seep in the Recently Ice-Shelf Free Larsen B Area, Eastern Antarctic Peninsula
The recent ice-shelf collapse and enhanced food input from surface phytoplankton blooms were responsible for the shift from oligotrophic pre-collapse conditions to a phytodetritus-based community with high densities and low diversity. Expand
Deep-Water Chemosynthetic Ecosystem Research during the Census of Marine Life Decade and Beyond: A Proposed Deep-Ocean Road Map
Based on 8 years of investigations of deep-water chemosynthetic ecosystems worldwide, highest priorities for future research are continued exploration of the deep-ocean ridge-crest; increased focus on anthropogenic impacts; and concerted effort to coordinate a major investigation of thedeep South Pacific Ocean.

First evidence of widespread active methane seepage in the Southern Ocean, off the sub-Antarctic island of South Georgia
An extensive submarine cold-seep area was discovered on the northern shelf of South Georgia during R/V Polarstern cruise ANT-XXIX/4 in spring 2013. Hydroacoustic surveys documented the presence ofExpand
Long-term iceshelf-covered meiobenthic communities of the Antarctic continental shelf resemble those of the deep sea
Since strong regional warming has led to the disintegration of huge parts of the Larsen A and B ice shelves east of the Antarctic Peninsula in 1995 and 2002, meiofaunal communities covered by iceExpand
Fracture-controlled fluid transport supports microbial methane-oxidizing communities at Vestnesa Ridge
Abstract. We report a rare observation of a mini-fracture in near-surface sediments (30 cm below the seafloor) visualized using a rotational scanning X-ray of a core recovered from the LomviExpand
Fracture-controlled fluid transport supports microbial methane-oxidizing communities at Vestnesa Ridge
We report a rare observation of a mini-fracture in near-surface sediments (30 cm below the seafloor) visualized using a rotational scanning X-ray of a core recovered from the Lomvi pockmark, VestnesaExpand
Ecophysiology and ecological limits of symbiotrophic vesicomyid bivalves (Pliocardiinae) in the Southern Ocean
Observations taken by remotely operated vehicle (ROV) footage show that the clams can live buried in sediment, or epilithically on the surface of rocks in diffuse geothermal flow, which indicates a range of ecophysiological flexibility for A. puertodeseadoi. Expand
Late Cretaceous (Maastrichtian) shallow water hydrocarbon seeps from Snow Hill and Seymour Islands, James Ross Basin, Antarctica
Fossil hydrocarbon seeps are present in latest Cretaceous (Maastrichtian) volcaniclastic shallow shelf sediments exposed on Snow Hill and Seymour Islands, James Ross Basin, Antarctica. The seepsExpand
Microbial Communities of Deep-Sea Methane Seeps at Hikurangi Continental Margin (New Zealand)
Despite outstanding features of Hikurangi seep communities, the organisms responsible for key ecosystem functions were similar to those found at seeps worldwide, which suggests that similar types of biogeochemical settings select for similar community composition regardless of geographic distance.

Biogeochemical processes and microbial diversity of the Gullfaks and Tommeliten methane seeps (Northern North Sea)
Abstract. Fluid flow related seafloor structures and gas seeps were detected in the North Sea in the 1970s and 1980s by acoustic sub-bottom profiling and oil rig surveys. A variety of features likeExpand
Microbial methane oxidation and sulfate reduction at cold seeps of the deep Eastern Mediterranean Sea
Abstract The Eastern Mediterranean hosts a variety of active cold seep systems, such as gas chimneys, mud volcanoes and pockmarks, in water depths of 500 to 3200 m. As part of the NAUTINIL expeditionExpand
Cold-seep assemblages on a giant pockmark off West Africa: spatial patterns and environmental control
A giant pockmark colonised by dense cold-seep assemblages near 3160 m depth along the CongoAngola margin has been surveyed by the ROV Victor 6000. The quantitative distribution of chemosyntheticExpand
Methane emission and consumption at a North Sea gas seep (Tommeliten area)

In situ fluxes and zonation of microbial activity in surface sediments of the Håkon Mosby Mud Volcano
From the Hakon Mosby Mud Volcano (HMMV) on the southwest Barents Sea shelf, gas and fluids are expelled by active mud volcanism. We studied the mass transfer phenomena and microbial conversions inExpand
Hydrothermal vents in turbidite sediments on a Northeast Pacific spreading centre: organisms and substratum at an ocean drilling site
18 vent species new to the Juan de Fuca Ridge were documented, including two new species of vesicomyid clams and a new mussel species, which are rare elsewhere on the ridge. Expand
Macrofaunal community structure and sulfide flux at gas hydrate deposits from the Cascadia convergent margin, NE Pacific
The rarefaction curves show a decrease in species diversity in the Beggiatoa and Calyptogena communities and the difference in the sulfide environment is a factor influencing the distribution patterns of the chemoautotrophy-dependant and heterotrophic species at the deep-sea sediments containing gas hydrate.
