Thanks to LéXPLORE, researchers took measurements during 24 hours, tackling the usual data gaps during night.
On 20th and 21st February 2020, 10 researchers investigated primary production and turbulences during 24 hour. A team took regular profiles of turbulences, while the other team took water samples for nutrients and chlorophyll-a, as well as vertical profiles of physico-chemical parameters. At the same time, a mooring was continously monitoring key parameters at fixed depths. In addition, the autonomous bio-optical profiler took vertical profiles every 3 hours, providing key information on the water column in real time. All these aquired data will be used to better understand the dynamics of primary production.
