attribute	NC_GLOBAL	acquisition_description	String	Sample collection: Mid-water trawls were conducted in the western Ross Sea, Antarctica on board the R/V Nathaniel B. Palmer in January-February 2018 (cruise number 18-01). The Issacs-Kidd Midwater Trawl (IKMT, 1.8 m frame, 500 um mesh, non-filtering cod end) was fitted with a calibrated General Oceanics flow meter. Four trawls were completed, each used to conduct a grazing experiment using the gut fluorescence/gut evacuation technique. Sampling stations for experiments 1-3 were located on the Continental Shelf Adjacent to the Ross Ice Shelf barrier near 76\u00baS, and experiment 4 was located on the continental shelf near 74\u00baS. Experiment 1 date and location: 1/16/2018; -76 00.044S, 176 59.909E Experiment 2 date and location: 1/18/2018; -76 45.024S, 172 01.733E Experiment 3 date and location: 2/6/2018; -76 27.063S, 168 07.142E Experiment 4 date and location: 2/16/2018; -74 49.955S, 164 34.177E Experimental Procedure: Immediately after each trawl (for each experiment), a subset of crystal krill, Euphausia crystallorophias, were processed for initial gut fluorescence and the other krill were sorted into experimental buckets for a time series sample collection. The krill collected for initial gut fluorescence were immediately measured for length, wrapped in foil, flash frozen in liquid nitrogen, and placed in a -80\u00baC freezer for later chlorophyll gut content analysis (see below). To determine gut evacuation rates, an additional 5 krill were processed immediately after collection for the initial time point, T0. The remaining krill were quickly sorted into five buckets to achieve a total of 12 krill per bucket. Each bucket was filled with 15L of 0.2\u00b5m filtered seawater, and 4.0 mg of activated granular charcoal powder was added at a final concentration of 265 \u00b5g L-1. The filtered seawater was maintained at in situ temperature in a cold incubator room for the duration of the 24-hr experiment. One krill per bucket was removed at time points of 5, 10, 15, 20, 25, 30, 40, 50, 60, and 120 minutes, yielding a sample size of five krill per time point. Finally, 1-2 krill were removed after 24 hours to obtain background gut fluorescence which is to be subtracted from all the other krill fluorescence samples. All krill removed at each time point were measured for standard length, wrapped in foil, flash frozen in liquid nitrogen, and placed in the -80\u00baC freezer. \u00a0Analyses: Fluorometric analysis was then conducted on the krill samples using a Turner 10-AU Fluorometer before and after acidification. The analysis was performed in the dark to ensure that chlorophyll did not degrade during sample preparation and processing. Each krill was placed without homogenization into a 20mL glass scintillation vial where 5ml of 90% acetone was added to extract chlorophyll pigments. The samples were covered in foil and placed into the -20 \u00baC freezer for a 48-hr extraction. After this extraction period, the samples along with 3 prepared blanks of 5ml acetone were transferred to individual sample cuvettes. Each sample was placed in the fluorometer to obtain fluorescence values before acidification. The sample was then removed from the fluorometer, 2 drops of 1.2M hydrochloric acid was added, and the sample was placed back into the fluorometer to obtain values after acidification.

attribute	NC_GLOBAL	projects_0_description	String	NSF Award Abstract: The Ross Sea is the one of the most productive regions in Antarctica and supports large populations of several key species in the Ross Sea food web, including copepods, crystal krill (Euphausia crystallorophias), and Antarctic silverfish (Pleuragramma antarcticum). Copepods and crystal krill dominate the diets of Antarctic silverfish, the dominant fish species in the high Antarctic zone, and silverfish are a major link between lower (copepods, krill) and higher (fishes, marine mammals, flighted birds, Adélie and Emperor penguins) trophic levels. Despite the significance of these key species, there is limited understanding of copepod, krill, and silverfish mesoscale distribution, spatial structure of age/maturity classes, and their interactions with physical drivers within the Ross Sea. Autonomous underwater profiling gliders are a developing technology that offers the potential for providing high spatial, temporal, and depth resolution data on regional scales. The project will test the capability of a multi-frequency echo sounder integrated into a Slocum Webb glider with the aim of providing the first glider-based acoustic assessment of simultaneous distributions of three trophic levels in the Ross Sea. Complementary glider sensors measuring physical, chemical, and biological parameters will provide mesoscale and sub-mesoscale hydrographic information from which phytoplankton-zooplankton-fish interactions and the relationships between these organisms and physics drivers (sea ice, circulation features) will be investigated. The approach proposed here, glider acoustics, is relatively new and has the potential to be transformational for investigating food webs and the Ross Sea ecosystem. Researchers will modify and integrate an Acoustic Zooplankton and Fish Profiler (AZFP) multi-frequency echo sounder into a Slocum Webb G2 glider with the capability to differentiate between krill and other types of zooplankton, including copepods, and different sizes of krill and silverfish. The AZFP will be complemented with the existing glider sensors including a CTD, a WET Labs BB2FL ECO puck configured for simultaneous chlorophyll fluorescence (phytoplankton biomass) and optical backscatter measurements, and an Aanderaa Optode for measuring dissolved oxygen. The new sensor suite will be tested during a four-week glider deployment, where it will conduct acoustic surveys to map distribution and abundance of multiple zooplankton taxa and silverfish during the austral summer along the Terra Nova Bay polynya ice shelf and in adjacent continental shelf waters. The relationships between phytoplankton-zooplankton-fish distributions and the physical drivers of zooplankton and silverfish species and size distributions will be investigated. Coordinated ship-based acoustic sampling and net tows/trawls will be conducted multiple times during the glider deployment to validate glider acoustic-based species, size, and abundance measurements. Open accessible, automated data produced during this project will be made available through RUCOOL (Rutgers University Center for Ocean Observing Leadership) and THREDDS (Thematic Real-time Environmental Data Distribution System). The production of consistent, vertically-resolved, high resolution glider-based acoustic measurements will define a successful outcome of this project that should help in identifying the challenges in their use as a potentially cost-effective, automated examination of food webs in the Antarctic.
