The Geochemical and Environmental Research Group (GERG) at Texas A & M University has two gliders— Stommel and Sverdrup — currently deployed in the western Gulf. GERG has posted some recent data plots of sigma-t, chlorophyll and temperature on the GCOOS data portal.  Water temperature profiles showing upper ocean heat content can help us understand hurricanes in the Gulf of Mexico. Here’s a snapshot of images from the Sverdrup on GANDALF. (For larger images of these plots, please go to GANDALF Beta and click on the column labeled Plots).
