Sargassum is a scourge for fishing and tourist economy. CLS has developed an operational service for detecting and predicting the stranding of this algae.

Plastic in the marine environment is a growing issue. If most of the marine plastic debris are in micro plastic form, the most feasible way to collect these litters is when still in macro form. In order to do so, modeling of the way the accumulations grown and their locations at given period have to be identified.

Plastic waste in the oceans has disastrous consequences for the environment and human health, and Indonesia is the world’s second largest polluter. To help achieve this target, local stakeholders called on CLS to understand how waste moves throughout Indonesia’s waterways.

The automated Argo array has been measuring the ocean only since 1997. Marine animals have been monitored using Argos nearly from its beginning in 1978, and are carrying environmental sensors for slightly less time, but years now. Both measurements can be complementary, using existing data to fill in gap in the array.

Mermaids are autonomous floating seismometers drifting with the ocean current at a pre-specified depth. CLS is providing the service of data collection through IRIDIUM, but also proposes to host the data.

In times of sea-level rise and global warming, it is important to know exactly what processes take place around the coast and in the ocean. However, there are still major gaps in ocean observing. An international consortium of 55 partners organized through the EuroSea project is set to change this.

Along the Brest Atlantiques race, a number of challenges await the skippers, including the trip from Rio to Cape Town, which could lead skippers into icy waters. This is why the race organizers have contacted CLS, experts in icebergs monitoring services, to keep an eye on how the situation evolves in the roaring forties, and keep skippers safe.

During the Transat Jacques Vabre Race, the skippers will be in contact with the elements. But the challenges of nature will not prevent them from contributing to ocean sciences. Along their way, skippers will gather precious data to contribute to improving numerical weather modeling and understanding climate change.
