Marine and coastal ecosystems

Marine and coastal ecosystems is a research topic within Oceanography. Science Explorer counts 63k research works in it since 1950. 9.9% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the complex interactions between marine biogeochemistry, ecosystem dynamics, and environmental factors such as eutrophication, harmful algal blooms, and climate change. It explores the role of dissolved organic matter, nutrient limitation, and phytoplankton in the oceanic carbon cycle and highlights the impact of global warming on biological productivity and oxygen levels in the oceans.
