Ocean currents are a key component to understanding many oceanic and climatic phenomena and furthermore the knowledge we have of them is crucial for navigation and operational applications. Therefore, a key problem in oceanography is the estimation of the synoptic (or “big picture”, large-scale, simultaneous conditions over a broad area) velocity field. Thanks to satellite …
The Quasi-Analytical Algorithm was developed to derive inherent optical properties by analytically inverting the spectral remote-sensing reflectance. It is the algorithm used in the ESA Ocean-colour CCI project to retrieve particulate optical backscattering (bbp). Due to the high uncertainties still associated to QAA global retrievals of bbp, reliable accuracy estimates of the QAA are essential …
The quality of estimations for carbon export and sequestration depends on how well the spatio-temporal dynamics of non-algal particles in open ocean are understood. Non-algal particles include organisms such as bacteria or viruses, cell debris and other organic particles, as well as mineral particles, bubbles and plastics. The accumulation of these particles is only partially …
Recent research by ESA Living Planet Fellow Marco Bellacicco in the frame of project PHYSIOGLOB gives new insights on how the choice of the regression method influences the derived bio-optical relationships in optical and satellite oceanographic studies. The authors compare the results obtained with diverse regression methods on the same bio-optical data set and quantify …
After the end of the Living Planet Fellowship, Audrey was the EU coordinator for the GEO Blue Planet Initiative, hosted by Mercator Ocean International as part of the EU4OceanObs FPI Action funded by the European Union.
Living Planet Fellowship research project carried out by Audrey Hasson. Mode waters (MWs) transport a large volume of heat, carbon and other properties across basins at seasonal to longer time-scales and thus play a major role in the modulation of the Earth climate. In the context of anthropogenic global warming, unlocking the understanding of the MWs transport …
“As well as doing my research, it has been an invaluable opportunity to complement my knowledge about the ocean opening new interest’s pathways” After the end of the Living Planet Fellowship, Marco was a postdoc fellow at the ISMAR-CNR in Rome. He was working on ocean carbon from space and in synergy with autonomous …
William is a post-doctoral researcher working at LEGOS located in Toulouse, France. His research interests are investigating sea level change at global and regional scales. William particularly focuses his investigations on interannual to long-term changes. The main scientific questions of his research are: how is sea level changing? And why is sea level changing? To …
Living Planet Fellowship research project carried out by Marco Bellacicco. Phytoplankton is considered to be responsible for approximately 50% of the planetary primary production and is at the basis of the trophic chain. Large scale factors such as climate, ocean circulation, and mostly anthropogenic activities, affect phytoplankton biomass and distribution. For all of these reasons, …
Living Planet Fellowship research project carried out by William Llovel and Alice Carret. Global mean sea level rise is one of the most direct consequences of actual global warming. Since the beginning of the 20th century, global mean sea level experiences an unabated increase of 1.1-1.9 mm.yr-1 recorded by tide gauges. Based on satellite altimetry …
