title: Shapefile of the survey tracks of 'Mosaic 02' at the Regab pockmark (Northern Congo Fan)

description: The Regab pockmark is a large cold seep area located 10 km north of the Congo deep sea channel at about 3160 m water depth. The associated ecosystem hosts abundant fauna, dominated by chemosynthetic species such as the mussel Bathymodiolus aff. boomerang, vestimentiferan tubeworm Escarpia southwardae, and vesicomyid clams Laubiericoncha chuni and Christineconcha regab. The pockmark was visited during the West African Cold Seeps (WACS) cruise with RV Pourquoi Pas? in February 2011, and a 14,000-m**2 high-resolution videomosaic was constructed to map the most populated area and to describe the distribution of the dominant megafauna (mussels, tubeworms and clams). The results are compared with previous published works, which also included a videomosaic in the same area of the pockmark, based on images of the BIOZAIRE cruise in 2001. The 10-year variation of the faunal distribution is described and reveals that the visible abundance and distribution of the dominant megafaunal populations at Regab have not changed significantly, suggesting that the overall methane and sulfide fluxes that reach the faunal communities have been stable. Nevertheless, small and localized distribution changes in the clam community indicate that it is exposed to more transient fluxes than the other communities. Observations suggest that the main megafaunal aggregations at Regab are distributed around focused zones of high flux of methane-enriched fluids likely related to distinct smaller pockmark structures that compose the larger Regab pockmark. Although most results are consistent with the existing successional models for seep communities, some observations in the distribution of the Regab mussel population do not entirely fit into these models. This is likely due to the high heterogeneity of this site formed by the coalescence of several pockmarks. We hypothesize that the mussel distribution at Regab could also be controlled by the occurrence of zones of both intense methane fluxes and reduced efficiency of the anaerobic oxidation of methane possibly limiting tubeworm colonization.
description: This is a shapefile showing the survey tracks of 'Mosaic 02' at the REGAB pockmark. The survey was carried out with ROV Victor 6000 during the West African Cold Seeps (WACS) cruise in 2011 (RV Pourquoi Pas?). Areas were surveyed during the two mosaicking ROV dives 423 and 426.This work was supported by IFREMER and by SENSEnet.

title: Swath sonar bathymetry during SONNE cruise SO230 (MOCOM) with links to multibeam raw data files

description: Multibeam data were collected during R/V Sonne cruise SO230 leading to the Mozambique Basin. Multibeam sonar system was Kongsberg Simrad EM-120. Data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Simrad multibeam processing format (*.all) were recorded with Simrad SIS software running on Windows operating system. The dataset consists of 2004 files in which are compressed with ZIP (3 hours in one archive files). One dataset contains a measurement period of half an hour. Simrad data files can be processed using the software packages CARIS HIPS/SIPS or with the open source software package MB-System (http://www.ldeo.columbia.edu/res/pi/MB-System/).

title: Late glacial and deglacial age model and biomarker analyses of sediment core MSM05/5_712-2 from the western continental slope of Svalbard

description: The transition from last glacial to deglacial and subsequently to modern interglacial climate conditions was accompanied by abrupt shifts in the palaeoceanographic setting in the subpolar North Atlantic. Knowledge about the role that sea ice coverage played during these rapid climate reversals is limited since most marine sediment cores from the higher latitudes provide only a coarse temporal resolution and often poorly preserved microfossils. Here we present a highly resolved reconstruction of sea ice conditions that characterised the eastern Fram Strait - a key area for water mass exchange between the Arctic Ocean and the North Atlantic - for the past 30 ka BP. This reconstruction is based on the distribution of the sea ice biomarker IP25 and phytoplankton derived biomarkers in a sediment core from the continental slope of western Svalbard. During the late glacial (30 ka to 19 ka BP), recurrent advances and retreats of sea ice characterised the study area and point to a hitherto less considered oceanic (and/or atmospheric) variability. A long-lasting perennial sea ice coverage in eastern Fram Strait persisted only at the very end of the Last Glacial Maximum (i.e. from 19.2 to 17.6 ka BP) and was abruptly reduced at the onset of Heinrich Event 1 - coincident with or possibly even inducing the collapse of the Atlantic Meridional Overturning Circulation (AMOC). Further maximum sea ice conditions prevailed during the Younger Dryas cooling event and support the assumption of an AMOC reduction due to increased formation and export of Arctic sea ice through Fram Strait. A significant retreat of sea ice and sea surface warming are observed for the Early Holocene.
description: For the calculation of the PBIP25 and PDIP25 indices mean concentrations of the respective biomarkers and the following concentration balance factors were used: 0.0127 for PBIP25 and 0.0322 for PDIP25.

title: (Supplementary table S1) 133 flares detected wiht a single beam echosounder during POLARSTERN cruise ANT-XXIX/4 in March and April 2013

description: 133 flares were detected using the ship-mounted parametric single beam echosounder during R/V Polarstern cruise ANT-XXIX/4 in March and April 2013. Gas emission sites were found to originate at water depths between 130 and 390 meters below sea level (mbsl) on the northern shelf of South Georgia within cross-shelf troughs 1, 3, 4, 5, and 6. Flare heights in the echograms were between 10 and 220 m with an average of ~70 m.
