Observations from two gliders deployed in the southern Ross Sea from November 2022 through January 2023

Two gliders were launched in the southern Ross Sea and recorded data from November 2022 through January 2023 as part of the Plankton to Predators project. Sensors on the gliders included temperature, salinity, oxygen, fluorescence, optical backscatter and active acoustics; one glider had a photosynthetically active radiation (PAR) sensor and a passive acoustic monitoring sensor. From these data we quantified chlorophyll and particulate organic carbon concentrations, and also an estimate of krill and small fish (those data are not included in this submission). Data were decimated to 3-meter intervals for ease in analysis. The spatial extent of the glider observations ranged from 169.5–172.3°W and 77.4–76.4°S.
