Anna is an oceanographer and postdoctoral researcher at the Department of Earth Sciences of the University of Oxford. She holds a BSc (Hons) in Biology from the University of Barcelona, an MSc in Oceanography from the University of Southampton, and a PhD in Ocean Biogeochemical Modelling from the University of Oxford. Anna’s research focuses on …
POSEIDON aims to understand the response of ocean ecosystems to climate warming and extreme events (e.g., marine heatwaves). Long-term trends (> 23 years) in phytoplankton ecological indicators (biomass, size structure and phenology) will be analysed in different regions, encompassing a range of conditions found in the global oceans. POSEIDON will further investigate the spatiotemporal variability …
John studied Marine Biology and Oceanography at the University of Plymouth (United Kingdom) (2011 – 2015). During his time in Plymouth, he completed a one-year internship as a research assistant at Plymouth Marine Laboratory, where he developed a keen interest in ocean colour remote sensing and its applications for biological oceanography. Between 2015 and 2021, …
“I want to express my gratitude to the LFP programme and my managers in particular. The kind support I have received during these 24 months has been fundamental to the success of PYROPLANKTON in a particularly complex period at home regarding the work-family balance. I also strongly appreciate the programme’s genuine interest in supporting fundamental …
Living Planet Fellowship research project carried out by Joan Llort. In recent years, exceptionally large wildfires have been recorded in Australia, California, the Mediterranean region, and the Arctic. While there exists an established research effort on how Climate Change is leading these megafires and on how they are affecting land ecosystems, recent observations show that …
A recent paper investigates the role of Sea Surface Salinity (SSS) and Sea Surface Temperature (SST), together with Sea Level Anomaly and Argo profiles in Tropical Instability Waves (TIWs) in the equatorial Atlantic Ocean during the period 2010–2018. Tropical Instability Waves (TIWs) are a phenomenon in which the interface between areas of warm and cold …
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 …
