Oliver with out going in to alot of detail I will give you what i know in a nut shell.
This link is a service that is under a hundred bucks a year and i have already sent them a E-mail about possibly adding a region in your area as they already have so many.
The service in really good for the price

This service is allways upgrading with more features.
On the other end of the spectrum here is another service that is more expensive and has a comercial service that is close to $400.00 a month and offers features like being abble to give you the temperature down severail hundreds of feet not just the surface to be abble to see potential food gathering currents or if the SST reading is simply a shallow temperature
potentially putting you in the wrong area as we are alot like fish we and they really like certain temperatures/conditions.
Like I said this is the nut shell version so the reason the depth temperature is importaint is all the features are about conditions to narrow down a species preferred condition to narrow the target zone and where the food will most like be found with feature tools like SST Altimetry chlorophyll etc. all build plankton/food to start the food chain.

Adding the science comercial & sportfishing data to this information is as good as it gets and i would be alot lees interested in fishing with out it as it has the potential to turn fishing in to catching while providing hunting the best part of fishing in my opinion from any where with a view from outer space to track your adversary day & night from anywhere.
Adding this kind of information to eddies cyclonic anticyclonic intersections of thermoclines etc. is where you get paid like a CEO straight from king Neptune.
