Abstract

These data include bio-optical measurements made using the shipboard flow-through system within three hours of CTD casts conducted on the R/V Robert Gordon Sproul (SP2319, SP2320) between dates 2023-07-28 and 2023-08-19 along the Southern California coast. These data were collected to provide context for the incubation experiments that were also conducted on board. Incubations were comprised of dilution experiments to assess phytoplankton growth and microzooplankton grazing rates and dissolved o...

Bio-optical measurements of surface seawater were made using the shipboard flow-through system within three hours of a CTD cast. Measurements of particulate attenuation (cp) and particulate absorption (ap) at three wavelengths (λ = 470, 532, and 660 nanometers (nm)) were made with an AC-S spectrophotometer (serial number 94; Sea-Bird Scientific [WET Labs, Inc.]). Coincident measurements of particulate backscattering (bbp) at three wavelengths (λ = 470, 532, and 660 nm) were made with an ECO-BB3 (serial number 349; Sea-Bird Scientific [WET Labs, Inc.]) set in a custom enclosure (Dall’Olmo et al., 2009).
