Wind jets drive variable upwelling off northern Costa Rica and the Gulf of Panama. SST in upwelling areas oscillates from lows of 22C to highs of 28 to 30C over several days as the Papagayo and Gulf of Panama wind jets intensify and ebb again.

The Gulf of Panama upwelling is really cranking at the moment.

What Americans Lose If Their National Center for Atmospheric Research Is Dismantled - Eos Five ways dismantling NCAR will cost the American people, and two ways to save it.

This is a very clear statement from the Union of Concerned Scientists describing why NCAR must not be restructured, dispersed, and broken up.

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.

Although the fronts are weak, the combined maps suggest the 200 metre contour would be a favourable area for gamefish to find feed.

Chlorophyll levels fall off around the 200 metre mark, and there is a consistent southward current in the 100 to 200 metre depth zone off Whitianga.

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.

Yellowfin tuna are back in New Zealand and the summer recreational gamefishing is going off. What's going on?

Which level 2 SWOT product is this Lily? Are you accessing the files from PO-DAAC? I think it's time for me to see if I can use these data for my Fishing Maps product (www.fishingmaps.info) instead of, or in addition to, the 8km resolution Copernicus product that I currently use.

Horn Point Confirms Deep NOAA Cuts A nearly 50 percent reduction in federal funding for oyster restoration threatens to sharply reduce oyster production in the Chesapeake Bay, jeopardizing one of the region’s most successful environmen...

Our first direct hit. Oddly our oyster work is the most popular thing we do. Great return on investment for taxpayers funding bay restoration.

But in the southern hemisphere, the rotation around a high goes anticlockwise, as you can see in this large eddy off the coast of Sydney, Australia. So don't be confused by blogs written for American audiences. It's different down under.

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.

Chlorophyll data are sparse due to clouds and missing data, but indication are that chlorophyll is high in the cool water. The offshore cool water edge is a likely region to find plankton feed.

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.

Cloud-free Sea Surface Temperature off the Mahia Peninsula, on the east coast of New Zealand reveals distinct temperature variations north and south of a significant eddy. 🌊 #Oceanography #NewZealand

“Deliberately dismantling an institution so central to weather forecasting and climate change prediction would not only undermine scientific research, it would leave people across the nation less prepared for the dangers of a warming world."

The barbarians are attempting to burn down the nation.

‘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.

Trump is meeting with Vought today to see how they can advance this destructive plan.

Some have to learn the hard way, I guess. If they can learn when belief contradicts logic.

Climate.gov will re-launch under new URL thanks to a secret team of web ninjas | CNN A small group of writers and researchers are launching an ambitious effort to preserve key climate data that the Trump administration has taken offline, including the climate.gov website.

ABS Issues Full Class for Saildrone Surveyor, Setting New Benchmark for USVs Saildrone USVs are the world’s only unmanned platform to receive classification from ABS—no other USV or UUV has been fully classed by any classification society.

It's becoming ever more apparent that ships should focus on what the autonomous vehicles cannot do.
