Satellite data from Copernicus Marine and NOAA CoastWatch. Data from 23 October 2026

Frequently asked questions

What is Secchi depth?

Secchi depth measures underwater visibility in metres. Higher numbers mean clearer water. Anything above 15m is considered excellent; below 3m is poor. Our primary source (Copernicus Marine) provides Secchi depth directly from merged multi-satellite observations. The fallback source (NOAA VIIRS) derives it from Kd490 using the Preisendorfer relationship.

Where does the data come from?

Two satellite sources, used in priority order. Primary: Copernicus Marine Service (EU), which blends multiple satellites into a gap-free L4 product covering Secchi depth, chlorophyll, and suspended particulate matter at 4km resolution. Fallback: NOAA CoastWatch VIIRS sensor aboard Suomi-NPP for spots where Copernicus has coastal land masking.

What does chlorophyll indicate?

Chlorophyll-a concentration (mg/m3) is a proxy for phytoplankton density. Low values typically mean clear, nutrient-poor water. Elevated levels above 5 mg/m3 may indicate an algal bloom, which can reduce visibility and occasionally cause irritation.

What is SPM / turbidity?

Suspended Particulate Matter (g/m3) measures particles floating in the water column (sediment, runoff, organic matter). Higher values mean murkier water. Values above 10 g/m3 usually indicate recent storm activity or river runoff.

What is SST?

Sea Surface Temperature in degrees Celsius from the Copernicus OSTIA satellite analysis. This blends observations from multiple satellites into a daily global product at 0.05 degree resolution, giving reliable coverage for all coastal spots.

How often is the data updated?

The catalogue is split across six independently monitored daily runs. Copernicus L4 data typically lags by 1 to 2 days. NOAA VIIRS weekly composites update once per week. Both sources search a small area around each coastal point to find the nearest ocean pixel.
