Abiotic variable/human impact proxy Acronym Product definition Remote sensor and product calculation period Key references
Sea wave height (m) WAVE Wave model calculating the frequency, direction and energy of waves. Spectrum that considers ocean currents and assimilates the height of significant waves based on historical altimetry records and satellite directional wave spectra. MFWAM model, GLORYS12, Sentinel 1 SAR. Temporal resolution three hourly instantaneous at 20 km2 from 2007 to 2016. None*
Sea surface temperature (°C) SST Monthly nighttime temperatures of the sea surface, data derived from satellites infrared observations. MODIS Global Mapped 11 µm Nighttime Sea Surface Temperature (NSST) from Terra and Aqua satellites, monthly at 4 km from 2007 to 2016. Kilpatrick et al. (2015) **
Degree heating week (°C) DHW Sum of the weekly positive anomaly of the nocturnal sea surface temperature, compared to the monthly maximum of the adjusted climatology, over a 12 week period. SATcoral-SIMAR product according to NOAA Coral Reef Watch methodologies using weekly data from OSTIA and GHRSST-MUR, at 1 km from 2007 to 2016. Cerdeira-Estrada et al. (2019) ***
Chlorophyll-a concentration (mg m−3) CHL1 Chlorophyll-a concentration according to the GSM method, from the reflectance normalized to the original wavelengths of the sensor, without intercalibration.
