The Ocean State Report is an annual publication of the Copernicus Marine Service that provides a comprehensive and state-of-the-art report on current state, natural variations, ongoing changes in global ocean European regional seas.It meant to act as reference Union for scientific community, international national bodies, general public.Using satellite data, models reanalyses, situ measurements, 4-dimensional view (latitude, longitude, depth, time) blue (e.g.hydrography currents), white...
The Copernicus Marine Services State of Pacific Ocean analysis available data demonstrates that the ocean surrounding Islands is warmer, has higher heat content, with sea level rising at rates
Regional processes play a key role in the global carbon budget. Major ocean CO2 uptake at mid-latitudes counteracts release tropics, which is modulated by episodes of marine heatwaves. Yet, we lack essential knowledge on persistent heatwaves, and their effect sensitive areas. Here show, using 1985-2017 joint analysis reconstructions, reanalysis situ satellite data, that heatwaves occur major Average air-sea flux density changes from are strongest Pacific Ocean with 40 ± 9% reduction tropics...
Abstract. The MALINA oceanographic campaign was conducted during summer 2009 to investigate the carbon stocks and processes controlling fluxes in Mackenzie River estuary Beaufort Sea. During campaign, an extensive suite of physical, chemical biological variables were measured across seven shelf–basin transects (south–north) capture meridional gradient between open ocean. Key such as temperature, absolute salinity, radiance, irradiance, nutrient concentrations, chlorophyll a concentration,...
Abstract Marine heatwaves (MHWs) represent anomalously warm temperature conditions of seawater that may affect marine life and ocean biogeochemistry. Under such conditions, phytoplankton communities modify their structure functions, resilience is not assured. This study characterizes the impact MHWs on spring bloom in North‐Western Mediterranean Sea. Here, we synergistically combine autonomous observations from BioGeoChemical‐Argo floats, satellite‐based ecosystem model data, show MHW events...
<p>The operational production of data-assimilated biogeochemical state the ocean is one challenging core projects Copernicus Marine Environment Monitoring Service (hereafter CMEMS). In that framework, Mercator Ocean International in charge improving realism its global 1⁄4° coupled physical-biogeochemical simulations, analyses and re‐analyses, to develop an effective capacity routinely estimate ocean, including, amongst others,...
