Monthly ocean physics, biology, nutrients and carbonate chemistry at each project site since 1993, with climatology, anomalies, tested trends, marine heatwaves, water-column profiles and checks against your own field sensors.
These are the platform's Example Projects. Their sites are illustrative, but every value below is real Copernicus Marine reanalysis for that location. Sign in to analyse your own project sites.
Example project: illustrative registry data used to demonstrate OCIS. It is not a real project.
Anomalies and percentiles compare the latest month with the same calendar month in 1993–2022. Trends are Sen slopes of annual means with a Mann-Kendall test; the range is the 90% confidence interval.

Connect a temperature, salinity, pH, oxygen or chlorophyll sensor to this project under IoT Sensors and its monthly means are scored against the model here (bias, RMSE, correlation).
Potential temperature at 0.5 m. Rising values raise heat stress, lower oxygen solubility and strengthen stratification.

Marine heatwaves use a monthly version of Hobday et al. (2016): two or more consecutive months above that month's 1993–2022 90th percentile. Hypoxia threshold 62.5 mmol/m³. Surface pCO2 is converted from pascals to µatm.
Values come from Copernicus Marine reanalysis models assimilating satellite and in-situ observations, sampled at the model cell nearest the site. They describe the regional ocean state around a project, not measurements of the project itself, and cannot on their own attribute change to project activity.
