The LatMix Summer Campaign: Submesoscale Stirring in the Upper Ocean

摘要: AbstractLateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy at scales on order 100 km (the mesoscale) fairly well understood explicitly represented in modern eddy-resolving numerical models global ocean circulation. The same cannot be said for smaller-scale processes. Here, authors describe major field experiment aimed observing understanding processes responsible 0.1–10 km. Stirring varying intensity were studied Sargasso Sea eddy approximately 250 southeast Cape Hatteras. Lateral variability water-mass properties, microscale turbulence, evolution several patches inert dye with an array shipboard, autonomous, airborne instruments. Observations made two sites, characterized by weak moderate background mesoscale straining, to contrast diff...
