Biological collecting

 Biological specimens have long been collected at marine research sites. During the aforementioned expedition by the Challenger, more than 4,000 species of unknown marine life were discovered. Even today, marine organisms are collected using a variety of methods according to the purpose of the research in order to determine "where" in the ocean "what" organisms exist and "how many" they are. The collected biological samples are used not only for research on the physiology and ecology of individual species, but also to elucidate the interaction between the global environment and marine organisms (ecosystems).
