Ocean Lagrangian Trajectories (OLTraj): Lagrangian analysis for non-expert users

Lagrangian analysis is becoming increasingly important to better understand the ocean's biological and biogeochemical cycles. Yet, biologists chemists often lack technical skills required set up such analyses. Here, we present a new product of pre-computed ocean Lagrangian trajectories (OLTraj) targeting non-expert users, demonstrate how use it by means worked examples. OLTraj based on satellite-derived geostrophic currents, which allows one directly compare with other in-situ or satellite products. We anticipate that will foster interest in applications biology biogeochemistry.
