The Water Temp link is probably the most important link we use when fishing offshore.  There isn't always a clear picture do to cloud cover but when there you are able to see just where the temperature breaks are.  You can also typically tell whether or not there is current which can be vital especially when Marlin fishing in the deep.  Every day before we leave the dock I check this liink at least once to see if there is a clear water shot to help make my decision on where to fish a little bit easier.  Its amazing sometimes to see how the different currents interact and where the warm water ends up especially in the winter months.
