Well … it may be that the big bulge is just newly discovered giant vortices bumping into Indonesia.

Story here. Video here.

“Enormous vortices of water, measuring 60 miles across, spin their way across the sea at a deliberate pace—3 miles per day. Oceanographers have dubbed them mesoscale eddies for their middle size, larger than a wake formed by an aircraft carrier and smaller than a gyre. Each one is like an upside down mountain of water, held together by its own rotation and extending about 3,000 feet beneath the surface. In the video above, eddies show up as red and blue dots dancing around. (Red ones spin clockwise, blue ones counterclockwise.) Just how much water gets carried around by all these eddies?

Sea Levels are barely rising 0 – 3 mm per year according to the NOAA website Tides and Currents.

All the green arrows are only 0 – 3 mm per year.  There is some yellow arrows (3 – 6 mm). And a very few red. Sea level is dropping  in the Gulf of Alaska.
