Investigating ocean acidification off the Iberian Margin: Oceanographic results...
Salgueiro, Emilia; da Silva Magalhães, Vitor Hugo; Matos, Lelia; Rebotim, Andreia; Sousa, Fátima; Schweizer, Magali; González-Martín, MaríaABSTRACT: The EUROFLEETS+ CARBO-ACID cruise was carried out to investigate the ocean acidification effects on the carbonate organisms (coccolithophores, pteropods, foraminifera, and corals) along the W Iberian Margin. Samples of the water column, plankton, corals and sediments were collected to investigate the acidification effects since the pre-industrial Era until the present. These samples will allow not onl...
Sea surface temperature variations revealed by planktonic foraminifera at the P...
Mega, Aline; Salgueiro, Emilia; Rebotim, Andreia; Voelker, Antje; Cruz, Joana; Calvo, Eva; Abrantes, FatimaABSTRACT: 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 ...
The early–middle pleistocene transition in the gulf of Cadiz (NE Atlantic) – an...
Mega, Aline; Rodrigues, Teresa; Salgueiro, Emilia; Padilha, Mária; Kuhnert, Henning; Voelker, AntjeBesides the shift in dominant orbital cyclicity depicted in paleoclimate proxy records, the Mid-Pleistocene Transition or Early-Middle Pleistocene Transition (EMPT) was linked to a change in the deep thermohaline circulation. Those changes contributed to more intense and longer-lasting glacial periods and cooler sea surface temperatures (SSTs) during glacials. Within the Atlantic Ocean, the Iberian Margin is co...
Planktonic foraminifera evidence for surface-water conditions off Southern Port...
Mega, Aline; Salgueiro, Emilia; Voelker, AntjeCharacterized by a drastic change in the deep thermohaline circulation, the Mid Pleistocene Transition (MPT) was a global climatic event resulted in more intense and longer lasting glacial periods and cooler sea -surface temperatures. The present study's objective is characterized surface -water variations during the MPT interval at the mid -latitude southern Portuguese margin using planktonic foraminifera faun...
