Whale bones and macroalgae as source of nutrients and cations in the nearshore geoecosystem of Admiralty Bay (King George Island, Antarctica)

Rakusa-Suszczewski S., Nędzarek A.

Polish Journal of Ecology

2002

Vol. 50, nr 3

389-396

In the area of the western shore of Admiralty Bay (SSSI No 8), the remains of 52 whale skulls were found; along the shores of the entire bay 175 skulls were reported. These skulls of whales caught in the area at the beginning of the 20th century are now considered as protected elements of the landscape. Whale bones provide a continuous source of chemical elements and nutrients that are released into the environment; they also cumulate elements of anthropogenic origin, e.g. Pb. The bones of whales as well as macroalgae and penguin feathers might be the source of calcium, phosphorus, carbon, nitrogen and sulphur for the land ecosystem.

Radiocarbon Dating of Whale Bones from the 17th Century Whaling Sites at Gashamna, Hornsund, South Spitsbergen.

Two well-preserved whale bones, probably belonging to Finnback Whale (Balaenoptera physalus) where collected near remnants of an early 17th century Dutch/English whaling station at Gashamna, Hornsund, south Spitsbergen. They yielded three radiocarbon ages of 620+65 yrs B.P. and 670+75 and 675+80 years B.P. Corrections for the reservoir age of seawater, based on the ages of living marine shells, were applied to obtain a historical age of the bones (A.D):-350 yrs;-400 yrs; and -440 yrs. A result best fitting the age of the Main Whaling Period in Spitsbergen (1610-1640) was obtained with the application of the lowest figures (-350;-400). lt is suggested that the lowest figures (-350) should probably be applied for certain periods to radiocarbon-dated bones of global-range whales, such at the Finnback Whale which during their life repeatedly travel from the Arctic to the Antarctic and back.
