Abstract:

This dataset contains modeled particle trajectories data supplemental to Androulidakis et al., (2020). Included are the data used to prepare the publication figures, observational data sources, and modeled particle trajectories. Trajectories include the total monthly evolution of 100 particles released in the coastal area on 2010-05-01, 2010-06-01, 2011-07-01, and 2011-08-01 (Dominant Florida Current) as derived by the Hybrid Coordinate Ocean Model (HYCOM) in the Gulf of Mexico (GoM-HYCOM 1/50). The computation of the particle trajectories was based on the methodology by Garraffo et al. (2001), using currents derived from the GoM-HYCOM 1/50 simulation. 100 particles were released in the model surface layer of a grid with 0.02° distance (83°W-83.18°W, 23°N-23.18°N).

Purpose:

The particle pathways were computed to investigate the connectivity between the Cuban coastal waters under the effects of the mesoscale anticyclonic activity and the broader Straits of Florida and Atlantic Ocean.
