Bremerhaven

The provided articles do not directly mention Bremerhaven. One article discusses the discovery of an uncharted island in Antarctica by the research vessel "Polarstern," operated by the Alfred-Wegener-Institut. The other article focuses on the DEL ice hockey semi-finals featuring teams from Cologne, Mannheim, Berlin, and Munich. While the Alfred-Wegener-Institut, which operates the Polarstern, is located in Bremerhaven, the articles themselves do not focus on the city. Therefore, Bremerhaven's relevance is only indirect, as the home of a research institution involved in Antarctic exploration. The ice hockey article has no connection to Bremerhaven.
