Eddy-induced transport tensors in the Atlantic

This data set contains results from numerical simulations used to study stirring of water by mesoscale currents (“eddies”). This stirring leads to large-scale transport of oceanic properties (“tracers”). These eddy-induced transports can in turn be related to the large-scale tracer gradients, using a transport tensor. The concept is widely used to describe these transports in the real ocean and to represent them in climate models. The data in this repository include several tracer diagnostics and comprehensive transport tensors from two types of numerical simulations: (i) an idealized quasigeostrophic (QG) simulation of a double-gyre flow; and (ii) a comprehensive simulation in a general circulation model (GCM) of the entire Atlantic, based on the HYbrid Coordinate Ocean Model (HYCOM). Each field is in a form of longitude/latitude map in one model layer: top layer in the QG model, and layer 17 in the HYCOM model. This data are associated with the article: Kamenkovich, I., P. Berloff, M. Haigh, L. Sun, and Y. Lu: “Complexity of Mesoscale Eddy Diffusivity in the Ocean”, submitted to Geophysical Research Letters.
