Summary: | The continuous displacement of water not only allows adjustment of the temperature but distributes particles as nutrients, plankton in the ocean and seas, allowing the development and transfer of larvae. This study aims to simulate Lagrangian trajectories for different numbers of particles or "larvae" rather passive (setting a depth of dispersion) or active (allowing vertical movement of the particles). It also seeks to analyze the dispersion of the particles by using different databases (SODA,GLORYS,HYCOM). The project will consist of the following stages: 1. Improvement and development of existing software to work with the database SODA. 2. Development of programs to simulate the dispersion of particles with Lagrangian trajectories using SODA data. 3. The first part of the study will focus on the North Atlantic area to simulate thetrajectories of particles that are able to cross it. 4. In a second phase, It pretend simulate cases which involve larval own characteristics, to verify if the developed model reproduces its behavior. Information such as the time and place of spawning larvae and larval duration (planktonic larvae duration [PLD]) will be used. The PLD is a key factor because, once the larval stage finished, the larvae acquire own movement and not follow ocean currents. 5. In a third phase, the lagrangian model will be applied to the simulation of the dispersion of microplastics in the ocean currents. El desplazamiento continuo de agua no sólo permite la regulación de la temperatura si no que distribuye partículas como nutrientes, plancton en el océano y mares permitiendo el desarrollo y traslado de larvas. Este estudio tiene como objetivo simular trayectorias lagrangianas para diferentes números de partículas o "larvas" bien pasivas (fijando una profundidad de dispersión) o activas (permitiendo movimiento vertical de las partículas). Así mismo se pretende analizar la dispersión de las partículas usando los datos de las componentes U, V y W de la velocidad de las corrientes proporcionada por ...
