Regional sea-level budgets
Tide gauge, altimetry and land motion data are combined to separate the causes of local sea-level change, so projections can be adjusted for each coast.

Ocean and coastal science is the core science this platform stewards for the network. It explains how the ocean stores heat and carbon, how sea level, currents and waves change, and how these physical drivers shape coastal hazards and marine life.
Ocean science studies the physics, chemistry, biology and geology of the oceans and coasts. It informs 海平面上升, 风暴潮, marine heatwaves, acidification and fisheries change, all of which affect coastal populations and trade. In oceans and coasts, climate and hazards and biodiversity and nature, 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.
Tide gauge, altimetry and land motion data are combined to separate the causes of local sea-level change, so projections can be adjusted for each coast.
Sea surface and subsurface temperatures are compared with seasonal climatologies to identify marine heatwaves, their depth and their persistence.
Wave hindcasts and buoy records describe typical and extreme wave conditions for coastal design and port operations.

Models are checked against tide gauge records, altimetry and in situ profiles. Hindcasts of past storms and heatwaves test predictive skill.
| 核查 | 如何开展 |
|---|---|
| Budget closure | The sum of sea-level components is compared with observed change |
| Climatology consistency | 热浪 definitions state the baseline and threshold used |
| Model-buoy comparison | Wave hindcasts are validated against buoy records |
Coastal processes at fine scale and ice sheet contributions to sea level remain uncertain. Observations of the deep ocean and polar seas are sparse.
Assembled from the Nexus Standards area profile 海洋与海岸风险标准: the hazards it names, the 系统 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.
