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 …
The main objective of the Earth System Data Lab (ESDL) project is to establish and operate a service to the scientific community that greatly facilitates access and exploitation of the multivariate data set in the ESDL and by this means advances the understanding of the interactions between the ocean-land-atmosphere system and society. To this end, …
This project estimates of the air-sea flux of CO2 calculated from a suite of satellite products over a range of Atlantic Ocean provinces. It deploys state-of-the-art eddy co-variance methods to provide independent verification of satellite estimates of CO2 gas exchange over the Atlantic Ocean. The project provides Fiducial Reference Measurements from the AMT28 (from 23rd …
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 …
Regional sea level trends present large spatial patterns caused by natural variability (changes in winds, air-sea flux etc.) along with anthropogenic influences in the atmosphere. These sea level trends can be partially masked by random oceanic processes. Global mean sea level rise is one of the most direct consequences of the on-going global warming. Based …
High atmospheric CO2 levels may lead to acidification of the ocean with severe consequences on marine ecosystems. Estimates of CO2 fluxes at the air-sea interface strongly depend on the availability of partial pressure of CO2 at the surface ocean (pCO2), which is a critical parameter for a detailed study of the mechanisms involved in the ocean-atmosphere CO2 …
Royal Research Ship James Clark Ross started its roughly 4000 miles, 40 days voyage across the Atlantic Ocean at the end of September. It has been carrying out in situ measurements with an array of instruments including above-water radiometric optical sensors that measure upwelling radiance from the sea surface for validation of satellite ocean colour, …
Replay the live-transmitted from the Azores opening session of an event where world-class scientists met to discuss the latest developments in our understanding of Earth’s surface variations observed by altimetry. Radar altimeters record the surface topography along the satellite’s ground track. They precisely measure a satellite’s height above water, land or ice by timing the …
SAR altimetry missions are boosting new developments in fields that exploit the quality of high-resolution products for sea surface topography, wave height, and wind speed. To review recent progress in and discuss future plans for altimetry technology at coasts, 88 scientists from 28 countries met at the 11th Coastal Altimetry Workshop earlier this summer. Read more …
