What are the limiting factors for marine productivity?

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.

The Captain’s Orders
Read the log book Taxonomy to learn about ocean productivity and marine life classification. You will need external resources to help you answer some of the questions below. Make sure you make a note where you got your information. Answer the questions and complete the following tasks using the log book and your internet ready computer.
