Description: Para la determinación de las zonas de acumulación de basuras marinas en la demarcación atlántica española, se utilizaron modelos hidrodinámicos que ayudasen a entender cómo los patrones de circulación oceánica distribuyen la basura marina. Para ello, en el marco del proyecto CleanAtlantic, la Universidade de Santiago de Compostela y el Instituto Superior Técnico (Universidade de Lisboa) desarrollaron un modelo computacional lagrangiano que permite trazar el movimiento de la basura en el océano atlántico europeo.

Guide for shoreline segmentation in buffers using QGIS

Responsible Partner: INTECMAR
Date: December 2020
Download: Link
Description: The goal of this guide is to describe the methodology to obtain a GIS file that contains the coastal sections where the marine litter particles that arrived to the coast can be counted. Each coastline section is actually a polygon, consisting of a piece of coastline and a certain thickness, which is where the particle is considered to have beached.

Description: The present study analyses the effect of five different Tagus River discharge scenarios ranging from low to extreme on residence time (RT), exposure time (ET) and integrated water fractions inside pre-established Tagus estuary areas, to identify its most vulnerable areas to pollution.

Validation of a Lagrangian model for large-scale macroplastic tracer transport using mussel-peg in NW Spain (Ría de Arousa)

Responsible Partner: USC, INTECMAR & ARDITI
Date: May 2022
Download: Link
Description:In this work, a validation of a recently developed Lagrangian computational model to track the movement of macro plastics in seas and oceans is presented. This validation is performed on a regional scale, in the Ría de Arousa, one of the most important estuaries for mussel cultivation in northwestern Spain. During mussel cultivation in rafts, a type of floating plastic stick are released, the mussel-pegs. The potential of this study is that to compare the accumulation results of the model with the accumulation data collected on the Galician beaches.

Description: In this study, the potential sources and pathways of marine plastic litter reaching the archipelagos of the Macaronesia region (Azores, Madeira, Canary Islands and Cabo Verde) were assessed by coupling a particle tracking model (OceanParcels) with datasets for ocean currents (GLORYS12V1 and GLORYS2V4), waves (WaveWatch III) and wind (ECMWF ERA-Interim).
