24 ICE TRACKING ICEBERG DEATH Unusually North, 47 latitude south, a big iceberg 12 km long, disintegrates in water with a temperature above 10 C. The COSMO-SkyMed image was taken IN Atlantic about 1000 km east of the location of ECO40, in a sea particularly perturbed by the wind.

25 At 50 latitude south, about 900 km east of the route of ECO40, a large group of icebergs, the biggest of which are long some Km, moves pushed by winds and currents, forming a trail of debris. The two images were taken about 12 hours apart.

26 Copyright Copernicus data (2015)/ESA/e-GEOS Image Sentinel 1A (ESA). A large iceberg in fragmentation close to Shag Rocks, a group of four rocky islets located about 115 miles to the west of South Georgia. The rocks are in the north of the fragmented iceberg, whose length is about 10 km, and are visible as bright spots a little bit confused with many shards of ice.

27 Copyright Copernicus data (2015)/ESA/e-GEOS Image Sentinel 1A (ESA). About kilometers south of the iceberg of the previous image, other icebergs taken from C-band radar of Sentinel 1A. The varying shades of gray sea well represent the extreme variability of the wind in these latitudes. The radar picks up more signal (image clearer) where are stronger ripples on the surface of the water due to wind itself.

28 Copyright Copernicus data (2015)/ESA/e-GEOS Further south, at the snowy peaks of the South Orkney Islands (which rise up to 1200 m and appear dark in the radar because of the snow cover). At this latitude the sea contains a mix of water and ice crystals (frazil ice or grease ice) that follow the pattern of the current.
