dc.description.abstractABSTRACT: Global warming, resulting from increasing human emissions of greenhouse gases, is raising ocean temperatures, projecting an increase of 2.6 °C by the end of this century. With the aim of refining climate models and predicting future regional climate conditions more accurately, this study reconstructs sea surface water temperature during the current interglacial period, the Holocene, off the southwest coast of Portugal, through the analysis of associations of planktonic foraminifera. During this period, surface waters in the region south of Sines exhibited higher and more stable temperatures compared to those detected further north, in the Estremadura spur. The northern region, due to its geographical position, more prominently highlights short-duration cold events associated with polar ice melting and marine circulation.eng
dc.description.abstractRESUMO: O aquecimento global, devido ao aumento das emissões de gases de efeito estufa resultantes das atividades humanas, está elevando as temperaturas dos oceanos, projetando-se um aumento de 2,6 °C até o final deste século. Com o objetivo de aprimorar os modelos climáticos e prever com maior precisão as condições climáticas regionais futuras, este estudo possibilitou a reconstrução da temperatura da água superficial do oceano durante o presente período interglacial, o Holocénico, na costa sudoeste de Portugal, através da análise de associações de foraminíferos planctónicos. Durante esse período, as águas superficiais na região ao sul de Sines apresentaram temperaturas mais elevadas e estáveis em comparação com as reconstruídas mais ao norte, no Esporão da Estremadura. A região mais ao norte, devido à sua posição geográfica, evidencia de maneira mais proeminente os eventos frios de curta duração associados à fusão dos gelos polares e à circulação marinha.por
