CalCOFI holds 35,717 values of it from 35,717 sampling events in one dataset, 2016–2022, at the surface.R Winds blowing toward the equator along the coast push surface water offshore and pull cold, nutrient-rich water up from below: the engine of the California Current’s productivity.C

- Wind also mixes the surface layer: a windy spell deepens the mixed layer and brings nutrients up even far from the coast. needs a citation before it can be the pick

- Wikipedia Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water from deep water towards the ocean surface. It replaces the warmer and usually nutrient-depleted surface water. Upwelling · CC BY-SA 4.0 · rev. 1356825477
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.
