“…In winter, ice formation and the resulting brine rejection lead to a homogeneous surface mixed layer. Over shallow areas where strong winds enhance ice production, the convection will reach the bottom, and salt will accumulate and gradually increase density in the bottom water [Skogseth et al, 2005]. As shown in our ice tank study there was a strong correlation between salinity and TCO 2 due to rejection of both salt and TCO 2 from growing sea ice.…”

[1] During sea ice formation in polar areas, brine rejection increases the density in the underlying water column and thereby contributes to the formation of deep and intermediate water masses in the world ocean. Here we present evidence that dissolved inorganic carbon (TCO 2 ) is rejected together with brine from growing sea ice and that low temperatures may result in a significant change in the ratio of TCO 2 and alkalinity in Arctic sea ice compared with surface waters. Model calculations show that this sea ice-driven carbon pump affects surface water partial pressure of CO 2 significantly in polar seas and potentially sequesters large amounts of CO 2 to the deep ocean.Citation: Rysgaard, S., R.

“…The colder and fresher Arctictype water advected from Storfjorden around the southern tip of Spitsbergen is transported northward along the coast by the Sør kapp Current (SC). This current carries mainly Storfjorden surface water, which is a mixture of local meltwater that has been heated by solar radiation and Arctic water that has already been warmed in the shallow Barents Sea and advected into Storfjorden by the East Spitsbergen Current (Haarpaintner et al 2001, Skogseth et al 2005. Therefore, the Arctic-type water occupying the WSS is warmer and fresher than typical Arctic water (colder than 0°C and saltier than 34.8).…”

“…In contrast, the Barents Sea is influenced by a mix of several water masses, i.e. warm Atlantic waters, Arctic water and locally produced brine water, resulting in hydrographic characteristics that vary in time and with changing bathymetry due to topographic steering of water masses (Johannessen & Foster 1978, Harris et al 1998, Skogseth et al 2005. Sediment characteristics follow these oceanographic patterns and depth, with a high proportion of fine sediments (72.0−88.5% pelite, Table 2) in the Barents Sea (Ingvaldsen & Loeng 2009), and a coarser grain size (17.5−33.7% pelite, Table 2) in WS.…”

Cold seeps are sites where hydrocarbons, sulfide and other reduced compounds emanate from the seabed, providing the setting to fuel chemoautotrophic production. Microbial assemblages convert these com - ). The presence of obligate seep-associated faunal taxa demonstrates that chemoautotrophic production, fueled by methane and sulfur, influences benthic communities at these seeps. Further, total biomass was significantly higher at seep-impacted stations compared to controls (mean = 20.7 vs. 9.8 g wet weight sample −1 ), regardless of region. Four methane seep-influenced samples showed clear indications of seep impact, with reduced diversity and with a few species dominating, compared to controls. Our results demonstrate that the effect of methane seeps on the Svalbard shelf benthic community are highly localized (i.e. meter scale), reflecting strong gradients associated with the point-source impacts of individual seeps. Regional differences and the restricted spatial extent of focused emissions likely drive the observed complexity and heterogeneity at Svalbard cold seeps. These results provide key baseAmerican plaice Hippoglossoides platessoides in a dense field of chemosymbiotic polychaetes at a Svalbard cold seep.
