BRUVS (TM) - Fish and Benthic survey of Townsville Midshelf Reefs 2000-04-08 to 2000-04-10

The dataset comprises 624 individuals from 67 species of fishes, sharks, rays and sea snakes observed at around Townsville Midshelf Reefs using 18 baited remote underwater video stations (BRUVS(TM)). 

Approximately 3500 of the best images from all BRUVS (TM) projects are stored in a reference library.

Data recorded concern:
- classification of the habitat in the field of view (topography, sediments, benthos)
- the identity of fish and CAABCODES
- their time of arrival
- their behaviour (8 categories, including feeding on the bait)
- their maturity (adult or juvenile)
- their relative abundance (as MaxN = the maximum number visible at one time, or distinguishable at different times as separate individuals e.g. much larger/smaller, male/female)
- the time elapsed before MaxN and feeding occurs.

A custom interface has been developed by AIMS staff, using Microsoft Access, for reading and analysis of BRUVS(TM) tapes.

Landscape mapping informing Antarctic Specially Protected Area management

Antarctic Specially Protected Area (ASPA) No. 143 Marine Plain in East Antarctica is valued for its “outstanding fossil fauna and rare geological features” (ATCM XXXVI 2013) but scientific evidence to guide its protection is sparse. The fragile Sørsdal Formation contains diverse marine vertebrate and invertebrate fauna, preserving a unique record of Antarctic environmental conditions in the Pliocene (Quilty et al. 2000). Strict permitting and access conditions are in place for the ASPA but evidence-based guidance for decision makers on how to assess the risks to the values of the ASPA is minimal. 



We will present the results of geological mapping, aerial imagery collection, and field observations from Marine Plain to consider the impact of foot traffic and helicopter access to the ASPA and provide options for future monitoring and management. Surficial geology of the broader Vestfold Hills (a 400 km2 ice-free region in East Antarctica) was mapped at 1:2000 scale using aerial photos, satellite imagery, a digital elevation model, and field observations (McLennan et al. 2021, McLennan et al. 2022). From this regional-scale mapping, we show that the glacial sediments draping bedrock hills in Marine Plain are typical of the Vestfold Hills region and do not represent the vulnerable Sørsdal Formation or the thermokarst features considered unique to the ASPA. Polygons outlining recommended landing areas for helicopters in the Marine Plain ASPA were derived using a buffer around the Sørsdal Formation, lakes, away from the edge of steep bedrock slopes, and higher that the limit of Pliocene marine inundation. Our results show how foundational datasets like landform and geomorphology mapping can provide robust evidence to support informed ASPA management.

Generating Continental Scale Pixel-Based Surface Reflectance Composites in Coastal Regions with the Use of a Multi-Resolution Tidal Model

Generating continental-scale pixel composites in dynamic coastal and estuarine environments presents a unique challenge as the application of a temporal or seasonal approach to composite generation is confounded by tidal influences. We demonstrate how this can be resolved using an approach to compositing that provides robust composites of multi-type environments. In addition to the visual aesthetics of the images created, we demonstrate the utility of these composites for further interpretation and analysis. This is enabled by the manner in which our approach captures the spatial variation in tidal dynamics through the use of a Voronoi mesh, and preserves the band relationships within the modelled spectra at each pixel. Case studies are presented which include continental-scale mosaics of the Australian coastline at high and low tide and tailored examples demonstrating the potential of the tidally constrained composites to address a range of coastal change detection and monitoring applications. We conclude with a discussion on the potential applications of the composite products and method in the coastal and marine environment, as well as further development directions for our tidal modelling framework.

Relative sea-level records preserved in Holocene beach-ridge strandplains – An example from tropical northeastern Australia

Northeastern Queensland is a far-field site from ice caps formed during the Last Glacial. However, the region has experienced glacio-hydroisostatically driven coastal elevation change during the Holocene that generated a distinctive relative sea-level record. We tested whether this subtle vertical movement of the coast is recorded in the morphology and stratigraphy of the beach-ridge strandplain at Cowley Beach, which comprises a series of 36 prominent and several subdued or truncated beach ridges. Previous studies have shown that the strandplain records the long-term progradation of the coast, with the ridges comprising coarse-medium sand that was deposited during both fairweather (foreshore and berm facies) and tropical cyclone events (erosional unconformities; storm-surge deposits) over the past approximately 7 ka. We utilised a fine-scale digital elevation model of the strandplain to examine beach ridge morphology and to compare the elevation pattern with published Holocene sea-level data for the region. The overall elevation pattern of the strandplain surface is consistent with the regional sea-level history, that includes a highstand at around 6 ka BP generated by isostatic uplift, and the elevation of the berm facies matches well robust coral sea-level indicator data. We also modelled the strandplain topographic patterns that would result under stable and continually rising Holocene sea-levels. The frequencies of elevation classes across the strandplain are normally distributed when the strandplain is deposited during a period of stable sea level, and negatively skewed with a continually rising sea level, consistent with the expected patterns. The results indicate the sensitivity of the elevation of the top of the berm facies preserved in beach ridges to subtle changes in sea level (tens of cm over a thousand years). Our results further underline the utility of beach-ridge strandplains, a globally distributed coastal landform, for building relatively detailed regional records of sea level during the Holocene at sites currently lacking this information.

A two-part seabed geomorphology classification scheme; Part 1: Morphology features glossary (Version 2)

This brief report updates the ‘Two-part Seabed Geomorphology classification scheme’ of Dove et al. (2016) and presents a new glossary (Part 1) of Seabed Morphology features. This Morphology glossary is intended to provide marine scientists with an accurate and robust way to characterise the seabed. Each glossary entry includes a feature definition and a representative schematic diagram to support clear and consistent classification. Feature terms and definitions are primarily drawn from the IHO guide for undersea feature names, which are herein modified and augmented with additional terms to ensure the final feature catalogue and glossary encompasses the diversity of morphologies observed at the seabed, while also minimising duplication and/or ambiguity. This updated classification system and new glossary are the result of a collaboration between marine geoscientists from marine mapping programmes/networks in Norway (MAREANO), Ireland (INFOMAR), UK (MAREMAP), and Australia (Geoscience Australia) (MIM-GA). A subsequent report will present the (Part 2) Geomorphology feature glossary.

Implications of sponge biodiversity patterns for the management of a marine reserve in northern Australia

Marine reserves are becoming progressively more important as anthropogenic impacts continue to increase, but we have little baseline information for most marine environments. In this study, we focus on the Oceanic Shoals Commonwealth Marine Reserve (CMR) in northern Australia, particularly the carbonate banks and terraces of the Sahul Shelf and Van Diemen Rise which have been designated a Key Ecological Feature (KEF). We use a species-level inventory compiled from three marine surveys to the CMR to address several questions relevant to marine management: 1) Are carbonate banks and other raised geomorphic features associated with biodiversity hotspots? 2) Can environmental (depth, substrate hardness, slope) or biogeographic (east vs west) variables help explain local and regional differences in community structure? 3) Do sponge communities differ among individual raised geomorphic features? Approximately 750 sponge specimens were collected in the Oceanic Shoals CMR and assigned to 348 species, of which only 18% included taxonomically described species. Between eastern and western areas of the CMR, there was no difference between sponge species richness or assemblages on raised geomorphic features. Among individual raised geomorphic features, sponge assemblages were significantly different, but species richness was not. Species richness showed no linear relationships with measured environmental factors, but sponge assemblages were weakly associated with several environmental variables including mean depth and mean backscatter (east and west) and mean slope (east only). These patterns of sponge diversity are applied to support the future management and monitoring of this region, particularly noting the importance of spatial scale in biodiversity assessments and associated management strategies.

Geochemical characteristics of Palaeozoic petroleum systems in Northwestern Australia

Isotopic and biomarker analyses carried out on Cambrian to Permian oils and source rocks in the Arafura, Bonaparte (Petrel Sub-basin) and Canning Basins have been used to geochemically characterise five distinct petroleum systems within the Larapintine and Gondwanan Petroleum Supersystems. The Larapintine 1 Petroleum System is characterised by isotopically light, free hydrocarbons in the Arafura Basin (δ13Csat = -32 ‰ Arafura-1) which have been correlated to kerogens of similar isotopic signature within the Middle Cambrian Jigaimara Formation. The richness and maturity of these source rocks indicate that an effective Larapintine 1 Petroleum System may exist in the northern parts of the Arafura Basin. Larapintine 2 oils, with <i>Gloeocapsomorpha prisca</i>-type signatures, are found on the Barbwire-Dampier Terraces and Admiral Bay Fault Zone in the Canning Basin. These oils can be correlated to source rocks in the Early Ordovician Goldwyer Formation on the Barbwire Terrace and the Bongabinni Formation in the Admiral Bay Fault Zone by their diagnostic odd-carbon-number preference in the C15–C19 n-alkanes. Larapintine 3 oils are derived from Late Devonian marine carbonates in the Canning Basin and Petrel Sub-basin and have a diagnostic biomarker signature which includes a predominance of steranes relative to diasteranes and abundant gammacerane and 30-norhopanes, similar to those observed in the Late Devonian Gogo and Pillara Formations. Larapintine 4 oils are derived from Early Carboniferous marine, clay-rich mudstones in both the Petrel Sub-basin and Canning Basin. They are isotopically light (mean δ13Csat = -28 ‰) and have a unique terpane signature which has been identified within the Milligans Formation. Gondwanan 1 Petroleum System hydrocarbons, represented here by the Petrel-4 condensate, have a heavy isotopic signature (δ13Csat = -24 ‰) which, coupled with an abundance of the diasterane and diahopane biomarkers, indicates derivation from Permian deltaic source facies. Recognition of the diagnostic geochemical components of each Palaeozoic petroleum system has led to the identification of Permian-like isotopic signatures in some hydrocarbon accumulations in the Timor Sea that were previously attributed to Mesozoic sources.
