    This record describes sediment trap sample data collected as part of the 1991-1993 Tasmanian Slope Trophodynamics Study undertaken by CSIRO Division of Fisheries. 2 moored sediment trap arrays with <21 individual traps were deployed on a single date in November 1992 at two depths (305 and 952 m), allowed to remain open for various times, and retrieved in April 1993. Free-floating traps were also deployed for approx. 24 hr and 48 hr in November 1992 and April 1993, respectively. On recovery, samples were analysed for weight dry weight, chemical analysis for carbonate, reactive phosphorus, total carbon, total nitrogen, biogenic opal, and phytoplankton pigments, and sub-samples were also taken for SEM (scanning electron microscope) identification of phytoplankton species.

  • This record describes data from the Spectronus - Trace gas analyser based on Fourier Transform Infrared spectroscopy (FTIR) collected on the Marine National Facility RV Investigator Event voyage IN2015_E01. This was a trial voyage for the RV Investigator departing Hobart on the 29th January and returning to Hobart on the 18th of February, 2015. The Spectronus - Trace gas analyser based on Fourier Transform Infrared spectroscopy (FTIR) is manufactured by Ecotech and the University of Wollongong. It makes continuous online measurements of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), carbon monoxide (CO) and isotopologue del13C(CO2).
