Oceanic Shoals Commonwealth Marine Reserve - Sediment oxygen demand data of seabed sediments.
This resource contains geochemistry data for the Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea collected by Geoscience Australia during September and October 2012 on RV Solander (survey GA0339/SOL5650). This dataset comprises sediment oxygen demand data from the upper 2 cm of seabed sediments. The Oceanic Shoals Commonwealth Marine Reserve survey was undertaken as an activity within the Australian Government's National Environmental Research Program Marine Biodiversity Hub and was the key component of Research Theme 4 - Regional Biodiversity Discovery to Support Marine Bioregional Plans. Hub partners involved in the survey included the Australian Institute of Marine Science, Geoscience Australia, the University of Western Australia, Museum Victoria and the Museum and Art Gallery of the Northern Territory. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; sub-bottom acoustic profiles; physical samples of seabed sediments, infauna and epibenthic biota; towed underwater video and still camera observations of seabed habitats; baited video observations of demersal and pelagic fish, and; oceanographic measurements of the water column from CTD (conductivity, temperature, depth) casts and from deployment of sea surface drifters. Further information on the survey is available in the post-survey report published as Geoscience Australia Record 2013/38: Nichol, S.L., Howard, F.J.F., Kool, J., Stowar, M., Bouchet, P., Radke, L.,

- Statement
-
Bottom sediments were collected using either a Smith Macintyre grab or a box core. Bulk sub-samples (6.5 ml) of surface sediment (0-2 cm) were incubated in BOD bottles for ~24 hrs in the dark at sea surface temperatures. Dissolved oxygen concentrations (and saturation values) were measured at the start and finish of each incubation. Results were expressed on a per g dwt basis utilising a separate sample to measure %water. Analyses were corrected for blanks (filtered seawater). The accuracies of the O2 measurements were +/- 1 mg/L. The accuracy of the scale used to measure wet/dry weights was better than 1%.
Thanks to the crew of the RV Solander for help with sample collection.
