Introduction
I did my PhD at LOCEAN, Sorbonne University (Paris). I worked on the evolution of the halocline in the Arctic ocean using in-situ data and an operational system from Mercator Ocean.

Article
Full-text available
Low‐salinity waters in the upper Arctic Ocean, referred to as “freshwaters”, are cold and play a major role in isolating the sea ice cover from the heat stored in the salty Atlantic Waters (AWs) underneath. We examined changes in Arctic freshwater distribution and circulation since 2007 using the 1/12° global Mercator Ocean operational model. We fi...

We present the first sensor‐based profiles of the quasi‐conservative NO parameter obtained with an autonomous ice‐tethered buoy in the Arctic Ocean. Data documented the halocline in the Transpolar Drift and Nansen Basin in 2017. A NO minimum was found in the Nansen Basin on a σ‐horizon of 27.8 kg.m‐3 corresponding to the lower halocline, while a lo...
Thesis
In the Arctic Ocean, stratification is determined by salinity, unlike the mid-latitude oceans which are stratified by temperature. In other words, in the Arctic, salty water ends up at the bottom, even if it is warmer. The halocline of the Arctic Ocean is a 100-200m thick layer with strong vertical salinity gradients and is located between 100 and...

[[Accepted for publication in Journal of Geophysical Research: Oceans. Copyright (2020) American Geophysical Union. Further reproduction or electronic distribution is not permitted.]] Atlantic Water (AW) enters the Arctic through Fram Strait as the West Spitsbergen Current (WSC). When reaching the south of Yermak Plateau, the WSC splits into the S...

[[An edited version of this paper was published by AGU. Copyright (year) American Geophysical Union.]] The Atlantic Water (AW) inflow through Fram Strait, largest oceanic heat source to the Arctic Ocean, undergoes substantial modifications in the Western Nansen Basin (WNB). Evaluation of the Mercator system in the WNB, using 1,500 independent tempe...

In April 2017, the first Ice Atmosphere Arctic Ocean Observing System (IAOOS) platform equipped with biogeochemical sensors was deployed near the North Pole. Over the next 8 months it meandered southward with the ice, collecting measurements in the upper 250 m of Amundsen Basin, the Gakkel Ridge, Nansen Basin, and Fram Strait. Two distinct periods...
