stands in: temperature’s face, underway sea-surface reading
No definition of its own: the estimate is described by its derivation, under How.
EOV Subsurface temperature
CalCOFI holds 47,734 values of it from 47,734 sampling events in one dataset, 2010–2022, at the surface.R Temperature sets the water’s density, and so the layering that decides whether deep nutrients reach the sunlit surface; off California the warm years are El Niño years and marine heatwaves.C

- Sea surface temperature is the one ocean measurement a satellite takes everywhere every day, and a ship’s reading is what it gets checked against. needs a citation before it can be the pick
- A warm year off California is usually a lean one: warmer, more layered water brings fewer nutrients up, and the plankton the rest of the food web eats decline. needs a citation before it can be the pick

The measurement
Measured in i
One row per series, one cell per year, darker with more values — the same strip the front
door draws per dataset and a species page draws per taxon. Each row is one dataset's own
measurement_type; the label is written once, in the title above.

How it is measured
Why it matters
The familiar scale i
Bars are each series' 5th–95th percentile, the line its minimum to maximum, the ring its median;
the marks are metadata/measurement_scale.csv's, each hovering to its own source.

The release builds no climatology for this measurement, so there is no normal to draw a departure from.
