Les onades de calor marines (MHW, per les sigles en angl\u00e8s)<\/strong> s\u00f3n per\u00edodes prolongats de temperatures elevades del mar que es produeixen sobre \u00e0rees oce\u00e0niques extenses. Les MHW poden afectar tant a la superf\u00edcie com a nivells oce\u00e0nics m\u00e9s profunds i es registren a tots els oceans del planeta. A les darreres d\u00e8cades, i en associaci\u00f3 amb l’escalfament de la temperatura superficial del mar (SST), la seva magnitud i freq\u00fc\u00e8ncia han augmentat, generant impactes perjudicials sobre els ecosistemes, les ind\u00fastries marines i les activitats humanes.<\/p>

El mar Mediterrani \u00e9s una de les regions m\u00e9s afectades per les MHW, ja que ha experimentat un escalfament significatiu de les seves aig\u00fces en les darreres d\u00e8cades. Tant l’augment de la SST a causa del canvi antropog\u00e8nic a llarg termini com la conseg\u00fcent major freq\u00fc\u00e8ncia de MHW han estat produint efectes devastadors sobre els ecosistemes locals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Les onades de calor marines (MHW, per les seues sigles en angl\u00e9s) poden classificar-se en categories en funci\u00f3 de la seua intensitat. En Hobday et al. (2018) es va proposar una convenci\u00f3 de nomenclatura per a les MHW que estableix quatre categories basades en la intensitat m\u00e0xima observada. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
