Interpreting satellite maps for gamefishing involves looking for consistent patterns in SST, fronts, currents and chlorophyll (when available) over several days. Selecting the frontal zones is made easier by using the SST frontal gradient maps.

Nothing like a few sunny days in New Zealand to bring out the chlorophyll in Fishing Maps.

Are single pass Sea Surface Temperature (SST) images the best way to detect fronts for gamefishing? Checkout the new blog on the Fishing Maps (zurl.co/zlvlj) website.

Consistent patterns in the sea surface temperature, currents, and chlorophyll create the structure that allows plankton concentrations to develop over several days. In this example off Tutukaka, New Zealand, over a 4 day period, SST is cool inshore of the 100 metre line.

We know the southern hemisphere is special, but what's that got to do with ocean eddies? In the northern hemisphere, high sea surface height (SSH) in the centre of an eddy is associated with clockwise rotating currents.

There are strong sea surface temperature (SST) contrasts off the Coromandel Peninsula, New Zealand, with cool water nearshore. The gradients are not sharp enough to produce well defined fronts, probably due to recent windy weather.

‘Wholesale destruction’: Government shutdown or not, critical science programs are at risk
The Trump administration has proposed devastating cuts to federal Earth and climate science programs, and a government shutdown could give them an opportunity to begin implementing those cuts.
