Fish stock assessment
Catch, effort and survey data are fitted in population models to estimate biomass and fishing mortality against reference points, with data-limited methods where records are short.
GCRI · Biodiversity Nexus
Ocean science provides the physics, chemistry and biology behind marine biodiversity risk: heat, acidity and oxygen in the water, the currents that connect habitats, and the stock assessments that tell fisheries managers how much can be taken. It links offshore change to coastal habitats and livelihoods.
Ocean science studies the physics, chemistry, biology and geology of the oceans and coasts. It informs bilindbûna asta deryayê, bilindbûna ava behrê ya bahozê, marine heatwaves, acidification and fisheries change, all of which affect coastal populations and trade. In biodiversity and nature, climate and hazards and oceans and coasts, ocean projections guide coastal defence, port planning and fisheries management. They link marine hazards to food security, shipping routes and coastal economies. The canonical description is on STEM Commons.

Satellite sea surface temperature is compared with the local climatology to compute accumulated heat stress, which is related to observed bleaching and mortality.
Ocean circulation models release virtual larvae to estimate which reefs and nurseries supply others, informing the design of protected area networks.

Assembled from the Nexus Standards area profile Standardên xetera cûrbecûrbûna jîndaran û xwezayê: the hazards it names, the pergalan and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

Models are checked against tide gauge records, altimetry and in situ profiles. Hindcasts of past storms and heatwaves test predictive skill.
| Kontrol bikin | How it is done |
|---|---|
| Retrospective analysis | Stock assessments are rerun with recent years removed to test for systematic revision |
| Satellite against in-situ | Remotely sensed temperature and ocean colour are compared with mooring and ship data |
| Bleaching hindcast | Heat stress metrics are tested against surveyed past bleaching events |
Coastal processes at fine scale and ice sheet contributions to sea level remain uncertain. Observations of the deep ocean and polar seas are sparse.
The sectors ocean science for marine biodiversity touches and how strongly they depend on each other: what a study has to observe and model together.
