Dr David Amblas, MSc, PhD

Marie Curie Postdoctoral Research Fellow at the Scott Polar Research Institute

Biography

Degree in Geology (2002) and PhD in Earth Sciences (2012) at the University of Barcelona (UB) for the thesis entitled "Sedimentary morphodynamics of siliciclastic passive continental margins", supervised by Dr. Miquel Canals and Dr. Roger Urgelés. He has been a member of the GRC Marine Geosciences group (UB) from 2003 to 2016. He benefited from training stays at the universities of Duke (USA), Florida State (USA), New Brunswick (Canada) and National Taiwan (Taiwan), amongst others. He is co-author of 32 peer-reviewed articles, 20 other publications including book chapters and scientific and educational material, and 90 conference contributions (22 as a first author) at international venues. He has participated in 23 research cruises in the Mediterranean Sea, the Atlantic, Pacific and Arctic oceans, and off Antarctica (2 as IP). He has been actively involved in 34 Spanish and international research projects where he has provided marine geology expertise in research fields as diverse as climate change, tsunami risk, habitat mapping, offshore wind power and fisheries management. From 2007 to 2016 he has been the responsible of the geophysical equipment of the research vessel "Lluerna" (19 m length). Main contributions of his research are the knowledge of submarine canyons evolution (e.g. Geology, 2012) and the long-term effects of bottom trawling to the seascape over large spatial scales (Nature, 2012).

Research

My research at SPRI aims to study the seafloor imprint of the dense water formed on the continental shelf of some marine regions around the globe, with a special emphasis on high latitude areas. The formation of dense shelf water is an atmosphere-driven seasonal phenomenon that occurs when surface waters over the continental shelf become denser than surrounding waters (by cooling, evaporation or sea-ice formation with brine rejection) and sink, generating a near-bottom gravity flow that moves downslope along the seabed. This process contributes to deep-ocean ventilation, plays a role in the global thermohaline circulation (and hence global climate), and involves the massive transfer of energy and matter (including sedimentary particles, organic carbon and pollutants) from shallow to deep waters.

The formation of dense shelf water is highly sensitive to temperature changes in both the lower atmosphere and the sea surface. In the coming decades global warming will likely modify its frequency and intensity, which could significantly affect the functioning of the deep-sea ecosystems. Overall, dense-water formation is expected to decline particularly in Arctic and sub-polar latitudes where sea-ice production is declining.

This research aims to contribute to a better understanding of the past and future effects of climate change on the formation of dense water through the analysis of its morphological and stratigraphic signatures, and through the use of numerical and experimental models. This project is funded by the European Union's Horizon 2020 under the Marie Skłodowska-Curie programme (grant agreement No 658358).
