All variables are provided using two different input as velocity fields;;
GlobEkmanDt : MULTIOBS_GLO_PHY_REP_015_004 downloaded from E.U. Copernicus Marine Environment Monitoring Service (CMEMS, http://marine.copernicus.eu/). This was produced by combining the altimetry derived geostrophic velocities and modeled Ekman surface currents. It had a spatial resolution of 0.25¡ and a temporal resolution of one day. ;;
GloryS12 : GLOBAL_REANALYSIS_PHY_001_030 downloaded from E.U. Copernicus Marine Environment Monitoring Service (CMEMS, http://marine.copernicus.eu/). It was obtained by a NEMO model assimilating altimetry and other observations. It had a spatial resolution of 1/12¡ and a temporal resolution of 1 day;;
;;
All variables are provided as mean and 25, 50 and 75percentiles of all virtual particlesintroduced in the stadium defined by the start and end position of each station;;
For all lagrangian diagnostics, advective times (Days backward) of 5, 10, 15,20, 30 and 60 days were used;;
;;
Variable label is constructed to reflect the variable_VelocityFieldSource(_AdvectiveTime)_MeanOrPercentile;;
