10th edition of the Copernicus Ocean State Report (OSR10)
As part of the Copernicus Marine Service, the annual Copernicus Ocean State Report (OSR) is the key tool of its ocean reporting framework. The OSR reports on the state, variability, and ongoing changes in the marine environment of the global ocean and the European regional seas over the past decades up to close to real time. Using observation-based (remote sensing, in situ) and ocean reanalysis data, the OSR provides a comprehensive 4-dimensional (latitude, longitude, depth, and time) analysis of the Blue, Green, and White Ocean. The OSR is intended to act as a reference, providing a unique ocean monitoring dashboard for the scientific community and for policy makers and others with decision making responsibilities.

AMOC in Focus: Joint Assessment Report of JPI Climate and JPI Oceans
The AMOC in Focus Joint Assessment Report aims to synthesise the latest scientific knowledge on the Atlantic Meridional Overturning Circulation (AMOC), a key component of the Earth's climate system. Drawing on observations, palaeoceanographic records, and climate model simulations, the report assesses the current state and evolution of the AMOC, its future trajectories, and the evidence for a potential tipping point. It also examines the potential impacts and risks of a weakened AMOC for climate, sea-level rise, marine ecosystems, and society. Developed jointly by JPI Climate and JPI Oceans with contributions from over 50 international experts and the support of 11 countries, the assessment aims to clarify scientific evidence, uncertainties, and knowledge gaps, providing a balanced, policy-relevant synthesis to support informed decision-making and contribute to the IPCC's Seventh Assessment Cycle.
