Quantifying the role of submesoscale Lagrangian transport features in the concentration of phytoplankton in a coastal system Open
Food resources in the ocean are often found in low densities, and need to be concentrated for efficient consumption. This is done in part by oceanographic features transporting and locally concentrating plankton, creating a highly patchy r…
