Diatom assemblages as upwelling indicators in surface sediments off Portugal

PhD in Geological Oceanography - Paleoceanography from the Graduate School of Oceanography - University of Rhode-Island, USA. Scientific interests are focused on the oceanographic and climatic conditions that control productivity in the ocean, mainly in coastal upwelling areas, which are important CO2 sinks. Authored 110 ISI scientific papers with 1,550 citations and co-edited the books Reconstructing Ocean History: A Window into the Future and The Climate of the Mediterranean Region. Initiated paleoceanography / paleoclimatology research in Portugal, has participated in the education of more than 30 young researchers, and launched new research areas at the national level. PI in 6 nationally funded projects and responsible for the Portuguese participation in 8 European projects worth Euro. At present is the PI of project Cheking Coastal Upwelling Related Diatoms' Biomarkers: Potencial Proxy for Primary Productivity Reconstructions (PTDC/AAG-GLO/3737/2012) with a total funding of 199.951Euros. Was director for the Marine Geology Department (1999 a- 2011), member of the scientific and/or executive committees of International programmes (IMAGES, IODP, MedCLIVAR, Magellan Workshop Series, IGBP-PAGES), and, national representative in the ESF-LESC core & standing committees.

Paleoceanography research discuss at the 42nd CIESM Congress

Our IPMA collaborators participated in the event that took place at the Centro de Congressos do Estoril in Cascais, from 7 to 11 October.

Our researchers and collaborators of IPMA participated in a day dedicated to the protection and defense of the oceans that took place at the National Museum of Natural History and Science of the University of Lisbon.

During the past week, our researchers Rui Santos, Fátima Abrantes and Francisco Leitão attended the National Meeting on Climate Change Research, where they were speakers in the presentation sessions.

The LIFE Ilhas-Barreira project was recently presented and the Centre for Marine Sciences (CCMAR) is one of the project partners and has the task of working with fishermen to reduce conflicts between this activity and some protected marine species.

This study led by the University of Salamanca and our researchers from IPMA aims to answer the call of the Southern Ocean Observing System Science Strategy to study the impact of ocean acidification these ecosystems.

Different diatom species present in the Antarctic Ocean determine the biological pumping of organic Carbon and biogenic Silicon in the Scotia Sea, according to a new study conducted with the participation of CCMAR researchers.

Fátima Abrantes, CCMAR researcher and senior researcher of the Portuguese Institute of Sea and Atmosphere, was distinguished with the "Ambassador Award – Union Award" for her excellence in scientific research, education, communication, and outreach.
