Poorly managed marine fisheries are in trouble around the world, researchers say, while ecosystem-based management is a powerful idea that in theory could help ensure sustainable catches - but too often there's a gap in translating broad concepts into specific action in the oceans that successfully meets these larger goals.

Sequence analyses of duplicated yolk genes of bony fishes yield new insights for their successful radiation in the oceans during the early Paleogene period

By absorbing half of the carbon dioxide emitted into the atmosphere, the oceans have a profound influence on climate. However, their ability to take up this carbon dioxide might be impaired as a result of climate change. To determine their response to global warming, ESA has backed two projects that provide systematic data on key oceanic variables - colour and temperature.

A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans - the growth of phytoplankton that forms the basis for the rest of the marine food chain - is tightly linked to climate change, and would be reduced by global warming.
