IN2023_V06 ACS data

This dataset consists of hyperspectral particulate absorption, particulate attenuation, and the first order (calculated) scatter coefficient from a Wetlabs Absorption and Attenuation Sensor (ACS). Data was collected from October 8th to November 1st 2023 aboard the RV Investigator (IN2023_V06). This voyage focused on sampling mesoscale eddies and across frontal features in a strong ecologically significant west boundary current, the East Australian Current (EAC). Throughout the cruise, the sensors continuously measured surface waters through the ships underway system, measuring 87 wavelengths (from 400-735 nm, with ~3 nm spacing) at a rate of 25 times per second. The data was later binned to 30 second intervals and aligned with the ships underway system (data for this can be found here: https://www.marine.csiro.au/data/trawler/survey_details.cfm?survey=IN2023_V06). Further information on the methodology for data acquisition and cleaning of the ACS data can be found in Mears et al., 2026.
