Abstract

This dataset contains fluorometric measurements of chlorophyll a from cruise RR2201 on R/V Roger Revelle (BLOOFINZ-IO, January-March 2022) in the Argo Basin region off NW Australia.

Seawater was collected with Niskin bottles on a CTD rosette, filtered onto GF/F filters and extracted for 24 hours at -20 degrees Celsius (°C) with 90% acetone. Samples were analyzed for chlorophyll a and phaeopigment concentrations by the acidification method with a Turner 10AU fluorometer.
