stands in: salinity’s face, thermosalinograph unit 1
No definition of its own: the estimate is described by its derivation, under How.
EOV Subsurface salinity
CalCOFI holds 50,169 values of it from 50,169 sampling events in one dataset, 2004–2022, at the surface.R Salinity tags the water masses: the California Current carries fresher Subarctic water south and the Undercurrent carries saltier water from the south; with temperature it sets density.C
other ways to say why · 4
- The thermosalinograph runs while the ship steams, so it fills the track between the stations the casts are taken at. needs a citation before it can be the pick
- Salinity and temperature together set seawater’s density, which drives the currents and decides how deep winter mixing reaches. needs a citation before it can be the pick
- Wikipedia Water mass source
- Wikipedia Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water. It is usually measured in g/L or g/kg. Salinity · CC BY-SA 4.0 · rev. 1368851206
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.
