99% of the water clear

22 passes over the water, in order, clouds left as holes (MetOp-B AVHRR, MetOp-C AVHRR, NOAA-21 VIIRS, NOAA-20 VIIRS).

The 74 °F break: a 7.0 °F step across it, seen on 14 of 22 passes. It held its line since Thursday.

No chlorophyll edge on this line (1.3× across). Sea surface 20 cm higher on the cool side, 1.1 kn geostrophic current on the line — a current edge.

The break sits 23 miles northeast of South Pass (Port Eads).

Every number is from the satellite passes. Where the water says to look — not where the fish are.

Water temperature at the grounds

Sea-surface temperature at each ground in season off Venice, Louisiana, on the 72-hour satellite composite of Nov 10–Nov 13: the mean of the clear water within 4 miles of the ground’s charted position. The last column is how far the break sits from it.

A satellite reads the surface of the water, not the water at depth.

A pass, a break, a composite

A pass is one satellite crossing the water once: it sees what the cloud lets it see and leaves the rest as holes. A break is a line the temperature steps across, and it only counts when more than one pass saw it. The composite fills the holes from the other passes of the same 72 hours.
