Marine National Facility - End of Voyage (EOV) Data - Published 30 Sep 2020
The collection includes output from an Australian national implementation of CSIRO's un-structured COMPAS hydrodynamic model to assess the Australian national tidal energy resource. The CSIRO COMPAS m... moreodel was run in 2-D (depth-averaged) mode on an unstructured grid having 183810 cells covering much of Australia's continental shelf and margin. Cell resolution is weighted, with higher resolution in regions with high tidal velocity and nearer to the coast, and is as fine as 500m in places, allowing the near-coastal flows to be simulated, but not the details of individual ports or narrow passages. The model was nested within the Oregon State University Tidal Prediction System (OTPS) 1/6degree global tidal model tpxo9v1 produced by Erofeeva et al (2002). During a calibration/validation phase, the model was run for 15 days using a variety of parameters and evaluated against a database of 683 sea level sites and 95 current velocity sites. COMPAS does not out-perform OTPS for sea level but does for current velocity. The mean (across all sites) of the velocity error is 7.1cm/s. At the sites with greatest observed tidal speeds (70-130cm/s), the magnitude of the vector error is significant at 20-30cm/s but still less than is available otherwise (to our knowledge) without using on-site observations. The collection includes two files: COMPAS_out66_AUSTEn.nc - includes hourly output of surface elevation (eta) and depth-averaged velocity components (uav, vav) on the unstructured mesh for the period of the simulation. CSIRO_tidal_const_v9.nc - includes elevation and velocity tidal constituents for 11 constituents (Q1, O1, K1, 2N2, N2, M2, S2, M4, MS4, M6, 2MS6), as derived using the t_tide package in MATLAB (Pawlowicz, 2002). This dataset is not certified as being fit for navigation purposes. Anyone using it for navigation purposes does so entirely at their own risk. The data set has known as well as unknown errors, largely due to idealizations embodied in the model configuration. Factors limiting model accuracy include the spatial resolution, lack of stratification, bathymetry errors, simple parameterization of bottom friction, absence of within-domain tidal body forcing and lack of non-linear interactions with non-tidal flows.less

Assessment of MMV methodologies for subsea CCS: seabed and water column monitoring - ASV - Published 12 May 2020
Measurements are made with a Battelle Seaology pCO2 monitoring system (ASVCO2) is similar to the system described in Sutton et al. (2014). A Seabird Prawler CTD (for Seawater Temperature and Salinity... more) is mounted on the keel, where the Dissolved Oxygen is measured by an Aanderaa optode. The pH is measured using a custom design pH sensor (SCRIPPS) based on a DuraFET sensor using either the internal of external reference (pHin, pHext). The seawater sensor intakes for the ASVCO2 , the Prawler CTD, the Aanderaa optode and the pH sensor are located at about 1m water depth. The CO2 measurement uses a bubble equilibrator (Sutton et al., 2014), where the air from the equilibrator headspace is circulated through a LI-COR 820 non-dispersive infrared detector (NDIR) for measurement of CO2. The system carries out an automated measurement sequence typically every 1 hour. At the beginning of each measurement sequence, the NDIR undergoes a two point calibration with a zero CO2 gas and a high CO2 standard span gas (typically 450-550 micromol/mol), which bracket the range of CO2 mole fractions in seawater and air. The zero CO2 gas is generated by cycling air through a soda lime chamber and silica gel to remove CO2 and water vapour, respectively. The CO2 span gas is prepared by the NOAA Earth Systems Research Laboratory in the USA and calibrated on the WMO X2007 scale with a standard deviation of 0.06 micromol/mol (http://www.esrl.noaa.gov/gmd/ccl/airstandard.html). Each measurement cycle of zero and span gas, equilibrator headspace, and air takes 20 minutes with the equilibrator headspace measurement occurring at about 17 minutes followed by the air measurement. The pressure measurements are considered the same for the equilibrator headspace gas and air measurements due to the design of the ASVCO2 system (Sutton et al., 2014) as are the temperature and salinity of the surface seawater and the equilibrator measured by the Seabird Prawler. The data from the ASVCO2, the Prawler CTD, and the pH sensor are transmitted through iridium, typically every 4 hours, whereas the optode data is received via Saildrone as part of 6 hourly netcdf files. The data is part of the calculations for fCO2 and gets added into the processed netcdf files. A. J. Sutton, C. L. Sabine, S. Maenner-Jones, N. Lawrence-Slavas, C. Meinig, R. A. Feely, J. T.

Assessment of MMV methodologies for subsea CCS: seabed and water column monitoring - ASV - Published 11 Apr 2020
Project Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of techno... morelogies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters. --o-- These are data from the 2017 San Fransisco sea trials trials (09-12-2017 to 15-12-2017) The WBT Mini echosounders were installed by Saildrone in San Francisco in November 2017 on two platforms – SD1007, SD1008.

Trials of two Saildrone platforms (SD1007, SD1008) were conducted between the 28rd March and the 7th of June 2018, commencing in Hobart and finishing in central NSW. The platforms were operated both... more on and off-shelf during this time. The WBT Mini echosounders had a selection of pre-programmed operation settings that were optimised for the particularly water depths. These were selected remotely by Saildrone operators who anticipated changing water depths. The acoustic systems were operated for the first 42 days of the 71 day mission, ceasing on the 9th of May at 17:50. The premature end to acoustic recording was presumably as a side effect of the technical difficulties that the Saildones had been experiencing due to high sea states where power allocation had to be prioritised to controlling the platforms. Additionally a controlled inter-calibration experiment was conducted east of Maria Island from the 5th April 20:30 UTC to 6th April 05:48 UTC. For that experiment both Saildrone platforms and RV Investigator (Voyage IN2018-T1) acquired acoustic and carbon chemistry data in a series of designed movements that will allow comparison of measurements taken at the same time in the same water mass. Results of these experiments will be reported separately. Both Saildrone platforms were able to provide high quality acoustic data sets over a sustained 6-week period in shallow and deep-water situations. less

Four 10 cm and four 6 cm diameter sediment cores were collected at each of the study sites in the Gippsland area, Victoria. Cores were collected by hand and involved divers pushing the core into the s... moreediment to a depth of 10 cm depth and capping the core at both ends using rubber stoppers. At each site 4 cores of each size were collected for bacteria and infauna, replicated on 2 spatial scales, 1 m apart and 10 m apart. Sediment cores have been processed and analysed for infaunal diversity and abundance (top 10 cm of caore), bacteria DNA (0-2 cm core depth and 8-10 cm core depth) and infauna DNA (top 10 cm of cores); XRD, TC/TOC/TN and particle size will be analysed for some cores. less
Assessment of MMV methodologies for subsea CCS: seabed and water column monitoring - Diver Deployed Sediment Cores - Published 07 Apr 2020
Measurements are made with a Battelle Seaology pCO2 monitoring system (ASVCO2) is similar to the system described in Sutton et al. (2014). A Seabird Prawler CTD (for Seawater Temperature and Salinity... more) is mounted on the keel, where the Dissolved Oxygen is measured by an Aanderaa optode. The pH is measured using a custom design pH sensor (SCRIPPS) based on a DuraFET sensor using either the internal of external reference (pHin, pHext). The seawater sensor intakes for the ASVCO2 , the Prawler CTD, the Aanderaa optode and the pH sensor are located at about 1m water depth. The CO2 measurement uses a bubble equilibrator (Sutton et al., 2014), where the air from the equilibrator headspace is circulated through a LI-COR 820 non-dispersive infrared detector (NDIR) for measurement of CO2. The system carries out an automated measurement sequence typically every 1 hour. At the beginning of each measurement sequence, the NDIR undergoes a two point calibration with a zero CO2 gas and a high CO2 standard span gas (typically 450-550 micromol/mol), which bracket the range of CO2 mole fractions in seawater and air. The zero CO2 gas is generated by cycling air through a soda lime chamber and silica gel to remove CO2 and water vapour, respectively. The CO2 span gas is prepared by the NOAA Earth Systems Research Laboratory in the USA and calibrated on the WMO X2007 scale with a standard deviation of 0.06 micromol/mol (http://www.esrl.noaa.gov/gmd/ccl/airstandard.html). Each measurement cycle of zero and span gas, equilibrator headspace, and air takes 20 minutes with the equilibrator headspace measurement occurring at about 17 minutes followed by the air measurement. The pressure measurements are considered the same for the equilibrator headspace gas and air measurements due to the design of the ASVCO2 system (Sutton et al., 2014) as are the temperature and salinity of the surface seawater and the equilibrator measured by the Seabird Prawler. The data from the ASVCO2, the Prawler CTD, and the pH sensor are transmitted through iridium, typically every 4 hours, whereas the optode data is received via Saildrone as part of 6 hourly netcdf files. The data is part of the calculations for fCO2 and gets added into the processed netcdf files.

The CSIRO Coastal Environmental Modelling (CEM) team develops, maintains and uses the EMS software that allows investigation of the physical, sediment and biogeochemical processes in marine environmen... morets. This is achieved by a ‘driver’ hydrodynamic code into which are linked various libraries to perform sediment transport and biogeochemistry, all supported by a core library. The ‘driver’ may be any model that manages the tracers required for sediments and biogeochemistry. The sediment and biogeochemical libraries are stand-alone modules that are linked to the driver via an interface, and in principle may be linked to any hydrodynamic code. Currently the ‘drivers’ available are a full hydrodynamic mode, a transport model that uses offline data to advect and diffuse sediment / biogeochemical variables, and a box model. The hydrodynamic code may further operate in reduced dimensions of 1D, 2D vertically averaged or 2D laterally averaged. A waves and tracer statistic library also exist; the latter allowing various operations to be performed during run-time on any tracers supported by the driver (e.g. means, fluxes, vertical integrals). Additional software exists to generate the complex orthogonal curvilinear grids that are typically used for case studies. These grids allow variable resolution over the domain, useful for representing areas of interest with high resolution and less critical regions with coarser resolution. The curvilinear grid may also allow a dimensionality to be reduced from 3-D to 2-D within the same grid. This is useful when representing rivers or narrow estuaries, since the cross-river coordinate becomes very small in these areas and therefore becomes the defining grid size for setting the model time-step. Eliminating these small grid cells by making rivers or estuaries 2-D laterally averaged allows larger time-steps, hence a faster model. The curvilinear grids require dedicated software for visualizisation of model output, and the CEM supports several visualisation platforms to archive this. These software packages allow publication quality images and animations to be produced, and allow exploration of the data in 4 dimensions for analysis purposes.less
Legacy data - - Published 17 Mar 2020
A dataset of multiple simultaneous wave buoy observations collected in the 1970s, primarily for the use of the local Port Authority, has recently been released, and is available for research purposes.... more The measurements were conducted in Port Philip Bay (PPB), situated in the Australian state of Victoria. PPB is a semi-enclosed embayment with a continuous deepwater (>10m) fetch of around 40-50km, where the extreme wind climate is primarily driven by eastward moving frontal systems. The late 1960s and 1970s heralded the start of largescale offshore wave buoy deployments. For example, the JONSWAP experiment to measure spectral wave growth took place in the late 1960s and the New South Wales wave buoy network was installed in 1974 to monitor hazardous wave conditions. The data from these early field deployments are still relevant today given the significant expense in deploying buoys in remote conditions when compared to competing platforms (e.g. satellites) and inexpensive numerical modelling which can provide results at regional and global scales.less
