Marine Heatwave of Sea Surface Temperature of the Oyashio Region in Summer in 2010–2016

The sea surface temperature (SST) of the Oyashio region in boreal summer abruptly increased 2010 and high summertime SST repeated every year until 2016. Observations an ocean reanalysis show that this marine heatwave occurred not only at but also deeper depths down to 200 m. Furthermore, salinity parallel with temperature. rises indicate strengthening Kuroshio water influence. height velocity southward intrusion near coast weakened from accompanied by increase anticyclonic eddies Extension. much more frequent existence east first is closely associated weakening second intrusion. It suggested rise could a catch yellowtail ( Seriola quinqueradiata ) northern Japan.
