According to Spanish researchers, a temperature record has been measured on the surface of the Mediterranean Sea. With a median temperature of 28.71 degrees Celsius on Monday, the previous maximum value (28.25 degrees) from 2003 (28.25 degrees) was exceeded by almost half a degree, said the scientist Justino Martínez from the Catalan Research Institute for the Management of the Sea (ICATMAR ) on Twitter with. Records have been there since 1982, it said. ICATMAR is subordinate to the prestigious Spanish institute for marine research ICM.
When asked, ICM employee Emili Garci explained that the record came from measurement data from the European earth observation program Copernicus. It is not yet the final value, which will only be known in about a year. However, the median usually experiences only small deviations. It is the value that falls in the middle of a size-ordered data series. There are therefore just as many measured values below as above. The previous record, which was registered almost exactly 20 years ago on August 23, 2003, is now the final median value.
In this case, the median value is the most meaningful value, explained Martínez and Garci. “This means that if, for example, there is an unusually high value that is inappropriate or unrealistic, for example because of a measurement error, the mean is affected and can fluctuate significantly, while the median is practically unaffected.”
A study was only published in Spain on Saturday, according to which the water in the western Mediterranean is warming at a rate of around two degrees per 100 years. In some places, such as L’Estartit on the Costa Brava, it is even three degrees per century, researchers from the marine research institute ICM-CSIC wrote in the “Journal of Marine Science and Engineering”.
