Sub-Surface Temperatures and FishMap with Thermocline
SAGA Explorer provides global access to sub-surface temperature data down to 1000 meters. These are individual files you can download. It also offers a Thermocline product which combines all those layers into one file so you get a complete picture of subsurface conditions around you.
The Thermocline tool shows you the depth of the mixed layer in the ocean. And because we combine the tool with the preferred temperature ranges of 40 different fish species, it also shows you the depth in the ocean around you at which those preferred temperatures are located.
To top it off, we then create a Fishing Map showing you how the amount water at those preferred temperatures changes across the fishing area of interest to you. In short the FishMap identifies areas where opportunities to find your target species should be highest.
These data are found under the Fishing section of the Select GRIBs menu on the Select GRIBs page. Sub-surface temperatures are available at 12 levels from 10 m to 1000 m below the surface. All layers are forecast out 1 day into the future (regardless of the forecast duration you have specified elsewhere on the Select GRIBs page). Select the layer or layers of interest to you by tagging each with a light tap. Once your layers are selected for the region of interest to you press Download at the top of the Get GRIBs page. Data will be retrieved and presented on the View GRIB page. Things get even more interesting if you select the FishMap with Thermocline product on the Select GRIBs page! In this product, we merge all 12 sub-surface layers into a single file. You cannot download the FishMap with Thermocline product and one or more sub- surface temperature layers. Its one product type or the other. Since the FishMap with Thermocline contains ALL of the sub-surface layers it would be pointless to download both it and individuals sub-SST layers.
