Ocean colour and blooms
Satellite ocean colour estimates chlorophyll and detects harmful algal blooms, with coastal water corrections and in situ checks.
GCRI · 海洋与海岸
Earth observation measures the ocean surface and coast from space: temperature, colour, sea level, waves, ice, habitats and shoreline change. In this field it gives consistent records across vast and remote waters that ships and buoys cannot cover.
Earth observation and remote sensing gather information about the Earth’s surface and atmosphere from airborne and spaceborne sensors. They provide consistent, repeatable measurements over areas that are hard to monitor on the ground. In oceans and coasts, climate and hazards and biodiversity and nature, earth observation maps exposure, damage and environmental change across borders and sectors. It supports rapid assessment after disasters and long-term monitoring of risk drivers. The canonical description is on STEM Commons.
Satellite ocean colour estimates chlorophyll and detects harmful algal blooms, with coastal water corrections and in situ checks.
Decades of satellite images are analysed to measure where shorelines have eroded or advanced, distinguishing trends from seasonal variation.
Optical and radar imagery map mangroves, seagrass and reefs and their change, with accuracy reported by habitat type.

Products are assessed against ground reference data using accuracy matrices and independent samples. Cross-calibration between sensors checks consistency over time.
| 核查 | 如何开展 |
|---|---|
| In situ match-ups | Satellite estimates are compared with ship and buoy measurements |
| Tide correction | Shoreline positions are corrected for tide at image time |
| Accuracy by class | Habitat maps report accuracy for each class |
Clouds, revisit gaps and mixed pixels limit what can be observed. Changes in sensors and processing can create artificial trends.
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.

Processing levels are mission specific; Sentinel-2 runs from Level-0 raw data to Level-2A, and CEOS Analysis Ready Data sets the minimum for analysis.
Neutral outline of a published external standard or method, from its issuing body. Not a record of operation. Nexus does not perform, certify or approve any step shown. A gate or decision belongs to the party the source names. Level-1B and Level-1C add corrections; Level-2A adds atmospheric correction and scene classification.
