The service’s purpose is the distribution of data related to marine litter sources, drift and currents for registered users. The region of interest is the North sea, the English and Bristol Channels and the Atlantic coast along Ireland and French Brittany.
The Litter-tep service
It’s a daily service of maps with a 5 day forecast, using, to calculate the scattering of marine litter, the following CMEMS products as input:
The service provides maps, that can be downloaded
Estimated volumes of litter carried by rivers
In a first step, this volume is estimated from statistical analysis of the rivers flows
In a second step, the volume will be estimated from rainfall data.
Litters drift at sea of litter coming from rivers
A map for each river, with a 5 days forecast.
Floating litter volume
A global map of litter concentrations
Landing of litter
In a first step, concentrations of litters are on a grid.
In a second step, concentrations will be with the form of a line
The computation of the model runs on the C-TEP platform
In the end, for professional, public authorities and NGO’s, the objective is to provide a hindcast service. It will permit estimating the potential origin of litter stranded on a beach or area of the coast. This is an « on demand » service to suscribers.
