A Survey of the Macrocystis pyrifera (L.) C. Agardh Stocks on the East Coast of Tasmania, 1988

The results of this survey are based primarily on the first hand experience of Craig Sanderson who was doing his masters thesis at the time on aspects of the biology of Macrocystis pyrifera (Linnaeus) C. Agardh 1820. In need of significant beds of M. pyrifera for research much of the east coast was searched by boat. Significant stands (&gt;1/2 acre) were found at Darlington, Southerly Bottom (East North Bay), Fortesque Bay and George III Rock, (near Actaeon Island). The status of the few areas not visited was determined from anecdotal reports.

A Review and Meta-Analysis of Potential Impacts of Ocean Acidification on Marine Calcifiers From the Southern Ocean

Understanding the vulnerability of marine calcifiers to ocean acidification is a critical issue, especially in the Southern Ocean (SO), which is likely to be the one of the first, and most severely affected regions. Since the industrial revolution, ~30% of anthropogenic CO2 has been absorbed by the global oceans. Average surface seawater pH levels have already decreased by 0.1 and are projected to decline by ~0.3 by the year 2100. This process, known as ocean acidification (OA), is shallowing the saturation horizon, which is the depth below which calcium carbonate (CaCO3) dissolves, likely increasing the vulnerability of many resident marine calcifiers to dissolution. The negative impact of OA may be seen first in species depositing more soluble CaCO3 mineral phases such as aragonite and high-Mg calcite (HMC). Ocean warming could further exacerbate the effects of OA in these particular species. Here we combine a review and a quantitative meta-analysis to provide an overview of the current state of knowledge about skeletal mineralogy of major taxonomic groups of SO marine calcifiers and to make projections about how OA might affect a broad range of SO taxa. We consider a species' geographic range, skeletal mineralogy, biological traits, and potential strategies to overcome OA. The meta-analysis of studies investigating the effects of the OA on a range of biological responses such as shell state, development and growth rate illustrates that the response variation is largely dependent on mineralogical composition. Species-specific responses due to mineralogical composition indicate that taxa with calcitic, aragonitic, and HMC skeletons, could be at greater risk to expected future carbonate chemistry alterations, and low-Mg calcite (LMC) species could be mostly resilient to these changes. Environmental and biological control on the calcification process and/or Mg content in calcite, biological traits, and physiological processes are also expected to influence species-specific responses.

Baseline biogeochemical data from Australia’s continental margin links seabed sediments to water column characteristics

Surficial marine sediments are an important source of nutrients for productivity and biodiversity yet the biogeochemistry of these sediments is poorly known in Australia. Seabed samples were collected at &gt;350 locations in Australia’s western, northern and eastern continental margins during federal government surveys (2007-2014). Parameters analysed included measures of organic matter (OM) source (δ13C, δ15N and C:N-ratios), concentration (total organic carbon (%TOC) and surface area normalised TOC (OC:SA)) and bioavailability (chlorin indices, total reactive chlorins, total oxygen uptake, total sediment metabolism (TSM), sediment oxygen demand (SOD) and SOD and TSM normalised to TOC). The aim of this study is to summarise these biogeochemical ‘baseline’ data, and make contextualised inferences about processes that govern the observed concentrations.  The OM was mainly from marine sources and OC:SA broadly reflected water column productivity (MODIS). Approximately 40% of sediments were organic-poor by global standards reflecting seawater oligotrophy; ~12% were organic-rich due to benthic production, high water column productivity and pockmark formation. OM freshness varied due to pigment degradation in water columns and dilution with refractory OM in reworked sediments. δ15N values confirmed the importance of N2 fixation to Timor Sea productivity, and point to recycling of fixed nitrogen within food chains in Western Australia.

Still Images and Videos from Tasmanian Shelf survey

The Tasmanian Shelf survey was conducted on the Challenger in collaboration with the Tasmanian Aquaculture and Fisheries Institute between the 13-16th June, 2008 and 23rd February to the 14th March, 2009 (GA survey #0315). The survey was operated as part of the Surrogates Program of the CERF Marine Biodiversity Hub. The objective was to collect co-located physical and biological data to enable the robust testing of a range of physical parameters as surrogates of benthic biodiversity patterns.  A total of 55 video transects were surveyed from five study areas (Tasman Peninsula, Freycinet Peninsula, The Friars, Huon river, and Port Arthur channel) in water depths ranging from 15-110 m. Video was recorded to mini DV tapes, and copied to digital format. For further information on this survey please refer to the post-survey report (GA Record 2009/043 - Geocat #69755).

Australian Multibeam Guidelines

The Australian Multibeam Guidelines were established by the AusSeabed consortium. The guidelines provide recommended procedures for survey planning, data acquisition and submission. They are designed for a range of audiences, from those experienced in seafloor mapping using multibeam sonar systems, non-experts who are developing mapping capabilities, and those contracting seafloor mapping surveys using swath systems. 

These guidelines aim to improve interoperability, discoverability and accessibility of MBES system data, and encourage improved acquisition standards to better meet end-user requirements. We acknowledge that to achieve such an aim, adaptation of the project might be necessary and could impact time and cost. However, in most cases, the inconvenience of varying parameters will be outweighed by the increased utility of the data to a wider user base.
These guidelines aim to provide a standard set of requirements for seafloor mapping activities conducted in Australian waters and comply with international initiatives (such as Seabed2030) to ensure that national efforts can provide global impact. They are designed to complement the purpose-based requirements and associated documentation related to specific survey requirements (e.g., hydrographic surveys; seabed infrastructure planning or installation).

The guidelines include a broad examination of data processing and guidance for data submission with recommendations for all three types of swath acoustic data (bathymetry, backscatter and water column backscatter) relevant across all water depths and adopt international guidelines where appropriate. They do not include instrument preparation activities such as bench/workshop tests, personnel requirements, or provide survey costing information. This revision of the Australian Multibeam Guidelines (version 2) contains information previously published in the Seafloor Mapping Field Manual for Multibeam Sonar (Lucieer et al., 2018) as chapter 8 (Multibeam acoustics for marine monitoring) and, as such, will also succeed the Seafloor Mapping Field Manual for Multibeam Sonar as chapter 3 in the second release of the National Environmental Science Program (NESP) Field manuals for Marine Sampling to Monitor Australian Waters (Przeslawski and Foster, 2018). The decision to make this extension to the guidelines and inclusion in the NESP suite of Field Manuals was made by AusSeabed and the NESP to allow both initiatives to continue with a single reference document to inform seabed mapping and eliminate the complications and community confusion associated with the maintenance of two reference documents with extensive overlap.

RV Investigator Ultrafine Aerosol Volatility and Hygroscopicity (VH-TDMA) - Selected Voyages (2016 onwards)

The VHTDMA was constructed at QUT for measurement of ultrafine aerosol volatility and hygroscopicity. It uses electrostatic classifiers to select particles of a particular electrical mobility diameter, conditions them (using a thermodenuder and humidifier) and re-measures the particle diameter. The VH-TDMA is made up of three purpose built electrostatic classifiers and two condensation particle counters (CPCs). One TSI 3010 CPC and one TSI 3787 CPC.

The pre-classifier (used to select particles of a particular dry diameter) most commonly cycled between measuring 40, 100 and 150 nm diameter particles during IN2016_v02. For short periods other particle diameters were selected (20, 30, 60,80 nm), to examine features in the ambient size distribution. The thermodenuder was set to 250 °C for the majority of IN2016_v02, with short periods at other temperatures (150°C, 200°C). The relative humidity of the H-SMPS was set to 90% RH for most of the voyage, however it was periodically lowered for size calibration scans and to measure the deliquescence RH for ambient particles. The sample was passed through a nafion drier and inlet RH logged to ensure that dry particle diameter was selected i.e. RH &lt; 30%, the efflouresence RH for common marine salts.

Seafloor environments of the eastern Timor Sea, Northern Australia: Sediment oxygen demand of seabed sediments.

The Timor Sea and its tropical marine environment support significant and growing economic activity including oil and gas exploration. To reduce uncertainty in decision making regarding the sustainable use and ongoing protection of these marine resources, environmental managers and resource users require sound scientific information on the composition and stability of seabed environments and their biological assemblages. Surveys SOL4934 and SOL5117 to the eastern Joseph Bonaparte Gulf were undertaken in August and September 2009 and July and August 2010 respectively, in collaboration with the Australian Institute of Marine Science, with research collaborations from the RAN Australian Hydrographic Office, the Geological Survey of Canada and the Museum and Art Gallery of the Northern Territory. The purpose of these surveys were to develop biophysical maps, and deliver data and information products pertaining to complex seabed environment of the Van Diemen Rise and identify potential geohazards and unique, sensitive environments that relate to offshore infrastructure. This dataset comprises sediment oxygen demand measurments made on the upper 2 cm of seabed sediments.

An Initial Assessment of Estuarine Geomorphic Habitats as Indicators of Coastal Waterway Health

An important aim of the comparative geomorphology of estuaries project was to increase understanding of the environmental characteristics of near-pristine estuaries and provide a reference dataset for quantifying changes in habitat patterns in modified systems. It was anticipated that this aim would be fulfilled by identifying key geomorphic characteristics of the near-pristine systems that may be used to benchmark the current condition of, and quantify change within, 'modified' waterways. Here we provide examples of some very promising results obtained from our preliminary analyses of the geomorphic habitat area information contained within the GIS maps available on OzEstuaries.

Beagle Marine Park backscatter data 2018

This resource includes multibeam sonar backscatter data for Beagle Marine Park (Bass Strait) collected by Geoscience Australia (GA) and the Institute for Marine &amp; Antarctic Studies (University of Tasmania; UTAS) during the period 17 – 26 June 2018 on the RV Bluefin. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with co-investment by GA and UTAS. The purpose of the project was to build baseline information for benthic habitats in the Beagle Marine Park that will support ongoing environmental monitoring within the South-east Marine Park Network as part of the 10-year management plan (2013-2023). Data acquisition for the project was completed during three separate voyages: Phase 1 - Seabed mapping by multibeam sonar; Phase 2 – Seabed imagery acquisition by Autonomous Underwater Vehicle, and sediment sampling; Phase 3 – Survey of demersal fish communities using Baited Remote Underwater Video (BRUVs).  This dataset from Phase 1 comprises 11 backscatter grids derived from multibeam sonar data gridded at 1 m spatial resolution, covering a combined area of 364 km2. A detailed report on the survey is provided in: Falster, G., Monk, J., Carroll, A., Siwabessy, J., Deane, A., Picard, K., Dando, N., Hulls, J., Nichol, S., Barrett, N. 2019.
