The general purpose of the study is to be able to establish background knowledge on the ecosystem on the continental shelf of South Australia and the impact of upwelling/saline outflow events on microbial communities to ultimately develop a biogeochemical model of the region. Sampling was carried out during cruises conducted on board the RV Ngerin as part of the Southern Australian Integrated Marine System (SAIMOS). During each cruise, the physical, chemical and biological properties of the chlorophyll fluorescence maximum (DCM) layer were investigated. Flow cytometry data has been collected for picophytoplankton, bacteria and viruses. Six main stations have been sampled over the course of the study, five are located on the 100 m isobath, i.e. RS (35.508S, 136.278E), B2 (35.418S, 136.148E), B3 (35.258S, 136.048E), SAM2CP/B4 (35.168S, 135.418E) and SAM5CB/B5 (35.008S, 135.198E), and one from an offshore station (B1; 36.188S, 136.178E) located southwest of Kangaroo Island. Note that combining the distances between stations (14–25 nautical miles), the average component of the current velocity at middepth along the shelf (0.01 m s21) and the average speed of the vessel (i.e. 9 knots) indicate that different water masses were sampled at each station. Additional samples have on occasion been collected from the National Reference Station (NRS) at Kangaroo Island (35.832S, 136.447E) and the SA Spencer Gulf Mouth Mooring (SAM8SG, 35.25S, 136.690E), where the saline outflow occurs. Since July 2019 two additional BGC stations have been added to the SAIMOS sampling array: the SA Upper Spencer Gulf Mooring (SAMUSG, 33.111S, 137.709E) and the SA Gulf St Vincent Mooring (SAMGSV, 35.023S, 138.46E). {"type": "Polygon", "coordinates": [[[135.0, -35.9], [138.5, -35.9], [138.5, -33.11], [135.0, -33.11], [135.0, -35.9]]]} 135.0 138.5 -35.9 -33.11 Biosphere | Microbiota | Bacteria Biosphere | Vegetation | Phytoplankton IMOS Node | SA-IMOS | Southern Australian Integrated Marine Observing System Niskin Bottles Oceans | Bathymetry | Water Depth Oceans | Ocean Chemistry | Chlorophyll Oceans | Ocean Chemistry | Inorganic Matter Oceans | Ocean Chemistry | Nitrogen Oceans | Ocean Chemistry | Organic Matter Oceans | Ocean Chemistry | Phosphate Oceans | Ocean Chemistry | Silicate Oceans | Ocean Chemistry | Suspended Solids Oceans | Ocean Temperature | Sea Surface Temperature Oceans | Ocean Winds | Surface Winds Picophytoplankton Virus amount_of_bacteria_in_sea_water amount_of_picophytoplankton_in_sea_water amount_of_virus_in_sea_water concentration_of_chlorophyll_in_sea_water depth depth_of_chlorophyll_maximum latitude longitude mass_concentration_of_particulate_inorganic_matter_in_s ea_water mass_concentration_of_particulate_organic_matter_in_sea _water mass_concentration_of_suspended_matter_in_sea_water mole_concentration_of_nitrogen_in_ammonium_in_sea_water mole_concentration_of_nitrogen_in_nitrate_and_nitrite_in_sea_water mole_concentration_of_phosphorus_in_phosphate_in_sea_water mole_concentration_of_silicate_in_sea_water sea_surface_temperature wind_from_direction wind_speed Summary of biological and nutrient data collected from each station. documentDigital XLS README_BioExcel_summary_May2014onwards.doc documentDigital Explanation of column headings in excel summary document.
