The EGLACOM project is an Italian contribution to the International Polar Year (IPY). The main objective of EGLACOM is the geophysical and stratigraphic high-resolution study of an ice stream dominated marine depositional system of the Arctic margin in order to reconstruct the margin evolution locally from the Pliocene to the recent-most deglaciation, and to define the sedimentary architecture and seafloor morphology as it changed through time since the onset of glacial conditions. The target study area is the southern margin of Svalbard, and in particular the glacial sedimentary system fed by the ice stream once occupying the Storfjiorden glacial trough in the northern Barents Sea. Additional objectives are: 1) Study of oceanographic processes connected to the Polar front and hydrologic characterization of Storfjorden dense water plumes. This objective will be pursued by mean of integrated seismic oceanography: identification of the acoustic interfaces in the water column along the multichannel seismic (MCS) reflection profiles and calibration with conventional oceanographic data: continuous thermosalinograph (TSG) and ADCP data, surface water sampling (spilled from TSG pipeline) along transit transect, XBT (during MCS acquisition), and deep water sampling carousel (WSC) of bottles, on which CTD and SVP (Sound Velocity Probe) were fastened. 2) Study of the organic carbon utilization, degradation and transformation processes along the water column in order to estimate the efficiency of biological pumps in the sequestration and export of CO2; calibration of the biochemical composition of organic matter as paleoenvironmental proxy, by assessing biopolymers concentration in the sediment cores and its relationship with production/degradation processes. 3) Detailed analysis of sound velocity and of the variation of the wavelet shape along a MCS profile close to the area of the geophysical investigation carried out within the EU HYDRATECH project. 4) Geological characterization of fluid flow systems in the area (potential identification of seabed seepage, mud volcanoes, pockmarks, Bottom Simulating Reflectors connected to the presence of gas hydrates).
