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 tropical Atlantic is home to multiple coupled climate variations covering a wide range of timescales and impacting societally relevant phenomena such as continental rainfall, hurricane activity, oceanic biological productivity, atmospheric circulation in the equatorial Pacific. also connects southern northern branches meridional overturning receives freshwater input from some world's largest rivers. To address these diverse, unique, interconnected research challenges, rich network ocean...
Abstract In the pelagic foodweb, micronekton at mid-trophic level (MTL) are one of lesser known components ocean ecosystem despite being a major driver spatial dynamics their predators, which many exploited species (e.g. tunas). The Spatial Ecosystem and Population Dynamics Model is modelling approach that includes representation several epi- mesopelagic MTL functional groups. these groups driven by physical (temperature currents) biogeochemical (primary production, euphotic depth)...
Since mid-2019, meso-zooplankton and micronekton density hindcast (large past time series that are processed with time-consistent forcings) available regularly extended for the Copernicus Marine Service catalogue. The product (also known as MICRORYS) is computed using SEAPODYM-LMTL, Lower Mid Trophic levels model of Spatial Ecosystem And POpulation DYnamic Modeling framework. Meso-zooplankton organisms (200µm-2mm) constitute low-trophic level. These transported along water masses....
The strandings of common dolphin (Delphinus delphis) have been significantly increasing along the French coast since 2016, putting at risk whole population. These occur especially in winter, despite temporal variability remains high. Therefore, it is essential to understand distribution this species on a fine scale propose solutions reduce accidental captures. suite models SEAPODYM was used map spatio-temporal dolphins and their preys.Highly mobile, respond environmental variations move...
Illegal, Unreported, and Unregulated (IUU) fishing is a widespread problem that undermines global efforts to manage protect marine resources. IUU involves activities violate conservation laws, occur without proper reporting, or happen in areas with inadequate management. This practice depletes fish stocks, disrupts ecosystems, threatens the livelihoods of communities rely on sustainable fishing. According recent estimates, accounts for up 20% seafood catch, resulting an economic loss...
The mesopelagic zone, located between 20-100m in depth, represents 20% of the ocean’s volume. substantial biomass organisms inhabiting these zones, estimated at 5-15 billion tons, has recently attracted attention states, raising question possibility sustainable exploitation. In Northeast Atlantic, Maurolicus muelleri and Benthosema glaciale, most abundant well-studied fish species, stand out. Nevertheless, species are still largely unknown, stock assessments remain riddled with considerable...
An application of the Spatial Ecosystem And POpulation DYnamics Model (SEAPODYM) is developed for North Atlantic albacore (Thunnus alalunga) population. We investigate spatiotemporal dynamics this species, distinguishing influences environment and international fishing. Incorporating historical data (1960–2008), a maximum likelihood approach allows estimation biological parameters (thermal oxygen tolerance) stock spatial distribution varying over time. Juvenile are predicted in warm surface...
National and global priorities are increasingly focused on the concurrent marine fisheries challenges of food security, illegal fishing, declining resources. Molecular genetics electronic monitoring technologies can advance solutions to these challenges, particularly in surveillance seafood traceability, a growing number studies continues validate utility tools. What is needed next guidance support their wider, more conventional adoption implementation, either complementary or absence...
Robust prediction of population responses to changing environments requires the integration factors controlling dynamics with processes affecting distribution. This is true everywhere but especially in polar pelagic environments. Biological cycles for many species are synchronised extreme seasonality, while their distributions may be influenced by both prevailing oceanic circulation and sea-ice Antarctic krill (krill, Euphausia superba ) one such exhibiting a complex life history that finely...

Modelling marine predator foraging habitats is a widespread research approach for projecting species responses to rapidly changing Southern Ocean. Yet key remaining challenge understand how prey biomass within could affect success. Quantifying this using observed information challenging given paucity of synoptic data. Here, we investigated whether from mechanistic model, provide useful predictions pre-breeding arrival body mass macaroni penguins (Eudyptes chrysolophus) Marion Island,...
Abstract. Micronekton – small marine pelagic organisms around 1–10 cm in size are a key component of the ocean ecosystem, as they constitute main source forage for all larger predators. Moreover, mesopelagic micronekton that undergoes diel vertical migration (DVM) likely plays role transfer and storage CO2 deep ocean: this is known “biological pump”. SEAPODYM-MTL spatially explicit dynamical model micronekton. It simulates six functional groups vertically migrant nonmigrant (no DVM)...
Within Task 5.3 “Regional Observing system simulation experiments and process modelling”; CLS is in charge of improving an ecosystem module for the ocean mid-trophic levels (i.e. micronekton) that utilizes multiple in-situ satellite data as input to derive predictions different trophic including fish [D5.5] has potential be implemented into routine services supported by a future IAOOS. With physical biogeochemical variables becoming available real-time, real-time monitoring marine resources...
