biological oceanography

Biological oceanography is the scientific study of the animal and plant inhabitants of ocean waters. It is a branch of oceanography, a broader discipline concerned with all aspects of the world's oceans, including their physical and chemical properties, geological framework, and the life forms they contain. Marine biology, closely related to biological oceanography, also encompasses terrestrial organisms that depend on saltwater for survival.123

Biological oceanographers study how ocean phenomena influence the distribution of organisms, their adaptations to seawater properties, currents, light availability, and seafloor conditions. They investigate marine ecosystems, food chains, and predator-prey relationships. Research methods include collecting biological samples using nets and trawls, as well as remote sensing and in situ observation. Understanding marine life is crucial for fisheries, assessing the impact of pollution, and predicting weather and climate changes.342
