biogeochemistry of the ocean

Biogeochemistry of the ocean studies how elements like carbon, nitrogen, and nutrients cycle through marine ecosystems and the physical environment. It examines how these elements move between water, living organisms, and sediments, influencing climate, marine health, and global processes. For example, phytoplankton use nutrients and carbon dioxide for photosynthesis, affecting oxygen levels and carbon storage. Similarly, decomposition and sedimentation transfer elements to deeper ocean layers. Understanding these processes helps explain how oceans regulate climate, support marine life, and respond to environmental changes.
