Whale oil
The third German Antarctic Expedition (1938–1939) was led by Alfred Ritscher (1879–1963), a captain in the German Navy. The main purpose was to find an area in Antarctica for a German whaling station, as a way to increase Germany's production of fat. Whale oil was then the most important raw material for the production of margarine and soap in Germany and the country was the second largest purchaser of Norwegian whale oil, importing some 200,000 metric tonnes annually. Besides the disadvantage of being dependent on imports, it was thought that Germany would soon be at war, which was considered to put too much strain on Germany's foreign currency reserves. Another goal was to scout possible locations for a German naval base.
