The Ocean Decade is a 10-year framework initiative to identify, generate and use critical ocean knowledge to manage the ocean sustainably.

The Marine Protection Atlas (MPAtlas.org) was created by the Marine Conservation Institute to more effectively communicate levels of marine protection worldwide.

Seagrass meadows are important but one of the most threatened ecosystems globally. Here the authors analyse data about extent and density of seagrasses in Europe from 1869 to 2016, and find evidence of recent trend reversal for declining European seagrass meadows.

The Baltic Sea is home to some of the world’s largest dead zones, areas of oxygen-starved waters where most marine animals can’t survive. But while parts of this sea have long suffered from low oxygen levels, a new study by a team in Finland and Germany shows that oxygen loss in coastal areas over the past century is unprecedented in the last 1500 years. The research is published today in the European Geosciences Union journal Biogeosciences.
