Task – Release the Kraken


Biological oceanography is one of the most intriguing fields of oceanography. Many animals and plants in the ocean remain to be discovered. Marine biologists are just beginning to comprehend the ocean ecology, or relationships of the organisms with the ocean. Much marine biological research is focusing on how marine animals and plants interact with each other and the environment. The often involves a detailed knowledge of water chemistry and sometimes physical oceanography and marine geology as well as an understanding of basic biological processes.
