The upper ocean, atmosphere and their interaction over the North Pacific exhibit pronounced decadal to interdecadal variations. A diagnostic equation for analyzing the heat budget for decadal variability in winter sea surface temperature (SST) is derived that can properly account for subsurface geostrophic advection, and strong seasonal cycle in the depth and temperature of the ocean mixed laye...

In our ongoing search for bioactive substances from marine organisms, novel alkaloids have been isolated. Pinnatoxins and pinnamine, potent shellfish poisons, were purified from the Okinawan bivalve Pinna muricata. Pinnatoxins activate Ca channels. Halichlorine was isolated from the marine sponge Halichondria okadai. This compound inhibits the induction of VCAM-1. Drugs that block VCAM-1 may be...

O presente estudo objetiva descrever as ocorrências de branqueamentos dos corais e outros cnidários bentônicos no costão rochoso da Praia do Forno (Arraial Cabo, RJ), observadas em fevereiro (verão) maio (outono) 2019, relacionando-as com possíveis eventos aquecimento das águas superficiais oceano. As cartas anomalias térmicas foram obtidas pelo INMET os trabalhos campo desenvolvidos baseados P...
