Definition: marine heatwaves occur when ocean temperatures are imuch warmer than normal (above the 90% of the historical data in the area and time of year,
so-called marine heat spike) during at least five consecutive days (Hobday et al., 2016).
Data: daily near real-time (1/50º) and reprocessed (1/20º) sea surface temperature from the Copernicus Marine Service in the Mediterranean Sea.
The reference period for the climatology is 1982-2015.
Dtection in real-time (daily bulletin): maps of daily marine heat spikes (for the last available day)
and timeseries of regional sea surface temperture and marine heat spike for the current year.
Long-term variations (indicators): maps and timeseries of the annual marine heatwaves characteristics
(total days, mean and maximum intensity above the 90% threshold, mean duration and frequency) over the last four decades.
