We observed two different icebergs near the Antarctic Peninsula. One was one of the largest ever observed (160 km long). It calved from the Filchner Glacier. Fresher water field surrounded the iceberg and drifted together with the iceberg. The other glacier (800 m long) was aground in the Bransfield Strait. A strong current was flowing around this iceberg transporting away the freshwater that melted from the iceberg.
