Biological oceanography is the study of the living organisms in the ocean and their interactions with the marine environment. This field examines various aspects of marine life, including the distribution, behavior, and ecology of organisms such as plankton, fish, and marine mammals. Researchers also explore how these organisms respond to changes in their environment, such as temperature and nutrient availability. In addition to studying individual species, biological oceanography looks at ecosystems like coral reefs and deep-sea vents. Scientists analyze how these ecosystems function and the roles different organisms play within them. Understanding these dynamics is crucial for managing marine resources and protecting ocean health.
