BRUVS (TM) - Fish and Benthic survey of Heron Island 2014-06-23 to 2014-07-02

The dataset comprises 5097 individuals from 202 species of fishes, sharks, rays and sea snakes observed at around Heron Island using 56 baited remote underwater video stations (BRUVS(TM)). 311 images were captured from these cameras.

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.

Migration of foraminifera in Territory times in Australia

The distribution of marine Tertiary rocks in Australia is restricted to the western and southern coastal areas of the continent. The rocks represented are of Paleocene, Eocene, Miocene and Pliocene ages. Considerable material has been collected in stratigraphic sequence from many Tertiary localities in recent years and the detailed examination of the foraminiferal content of the rocks has yielded many startling discoveries.

Facies Evolution of Holocene Estuaries and Deltas: A Large-sample Statistical Study from Australia

Selected geomorphic features and sedimentary facies were mapped in 283 of Australia's wave- and tide-dominated estuaries and deltas to quantitatively evaluate established evolutionary facies models that depict the evolution of estuaries into deltas during stable sea level conditions. While diagnostic facies for wave- and tide-dominated estuaries and deltas approximate those specified by the models, statistical analyses of the data also reveal two additional insights regarding the evolution of estuaries to deltas. First, there is an offshore shift in the locus of sand accumulation between tide-dominated estuaries and deltas, associated with the onset of delta development. Second, the mean surface area of intertidal environments (i.e., intertidal flats, mangroves/melaleuca, saltmarsh/salt flat facies) is greater in wave-dominated deltas than in wave-dominated estuaries. Tidal penetration associated with the river establishing a more direct and permanent connection to the sea during late-stage development presents a natural impediment to continued formation of an alluvial plain and full development of the 'classic' wave-dominated delta morphology. A notional evolutionary pathway for wave-dominated estuaries is developed from the distribution of facies that predicts the rate and susceptibility of geomorphic and habitat changes. The 'classic' deltaic geomorphology may be unattainable for wave-dominated systems, except those with significant terrigenous sediment inputs. Our study is the first published example of geomorphic and sedimentary data assembled from a large number of wave- and tide-dominated estuaries and deltas across an entire continent.

Formation of the Lord Howe Rise continental ribbon during eastern Gondwana breakup from multi-channel seismic reflection data

The Lord Howe Rise continental ribbon, offshore eastern Australia, formed during the Late Cretaceous rifting of eastern Gondwana. This project focuses on multi-channel seismic reflection and bathymetry data collected on a multi-leg marine geophysical survey in 2016 to constrain the nature of rifting and the formation of the Lord Howe Rise. We present processed pre-stack depth-migrated seismic reflection images and interpretations of a regional, ~900 km long east¿west-oriented profile at 27.2°S, from the oceanic Tasman Basin to the extended continental crust of the Lord Howe Rise. We find that the Tasman Basin contains buried basins that may be related to early transform faulting. The Tasman Basin has a sharp eastern boundary against the Dampier Ridge, within which are multiple rift basins up to 3 km deep. These basins are similar to those found on the Lord Howe Rise. The Middleton Basin separates the Dampier Ridge and the Lord Howe Rise and is a broad, well-stratified sedimentary basin of up to ~3.5 km thickness. This basin contains an unconformity that separates strata conformable with the basement and post-rifting strata. Both syn-rift and post-rift sedimentary sequences are found on the Lord Howe Rise. To better understand these rifting events, we present grids of pre-stack time-migrated seismic reflection lines covering two rift basins of the Lord Howe Rise. The two basins show contrasting evolution, including variations in normal faulting within the syn-rift sequences. These results help constrain the dynamic processes that caused the formation of the Lord Howe Rise continental ribbon.

Port Curtis Integrated Monitoring Program - Bio Accumulation

PCIMP monitored across 15 sampling zones (54 water sites) in Port Curtis assessing the water quality and health of Port Curtis, with sites ranging from the Narrows in the north to Colosseum Inlet in the south. Included in the zones were sites within the State and Great Barrier Reef Marine Park zones.

Oysters

Three batches of ten (10) oysters were attached to buoys at each of the 54 sites across the Harbour. The oysters can accumulate metals from the water to provide an indication of the average concentration of metals in the water over the time they were deployed. Oysters were deployed two times a year in March and August and left in the water for approximately three months. Oysters are used to measure bioaccumulation of metals, metalloids and fluoride.

Biophysical Processes in the Torres Strait Marine Ecosystem II. Survey results and review of activites in response to CRC objectives

This report contains the preliminary results of Geoscience Australia survey 273 to northwest Torres Strait. This survey was undertaken as part of a research program within the Torres Strait CRC aimed at understanding marine biophysical processes in Torres Strait and their effect on seagrass habitats. Two Geoscience Australia surveys were undertaken as part of this program, survey 266 measured monsoon season conditions (Heap et al., 2005), and survey 273 measured trade wind conditions. Section 6 compares and contrasts the survey results acquired for both surveys. Section 7 addresses the results of the survey program in light of the objectives of the CRC proposal.
Survey 273 acquired numerous different data types to assist with characterising the mobile sediments and hydrodynamic nature of the region. Multibeam sonar, current meters, grab samples, vibro-cores, underwater video, meteorological data (from the Bureau of Meteorology), Landsat imagery, were all used to characterise the seabed hydrodynamics of Torres Strait.

AGSO Formats for Marine Seismic and Navigation Digital Data

This format description is designed to assist users of AGSO digital seismic data. In general  the standard descriptions have been adhered to as specified by Barry et. al. (Recommended Standardsfor Digital Tape Formats, Geophysics, vol 40, No 2 (April 1975) pp 344-352).

Trace header mnemonics for many of the entries are as per used by CogniSeis in their DISCO
software package, others have been defined by AGSO.

Variations to the standard trace header descriptions (bytes 1-180) are as follows. TRACED has expanded codes which are applicable to unstacked data eg. reformatted field data. Static corrections and delays are defined to account for the field acquisition system.

In addition to the standard entries a number of optional entries are also used. Some of these arecreated by DISCO and others relate to AGSO data acquisition and processing. The most importantof these are SHOT or SPN.

Please note that for AGSO data released prior to 1993, a pseudo shot point number was used (SPN)
as opposed to processing shot number (SHOT). The SPN was an assigned number generated from
the stack data set and usually started at 100. This number has no direct relationship to the original field shot number (FFID) or processing shot number (SHOT) and may be considered to be a re-sequenced CDP. Therefore the first SPN on a line may not occur at fall fold but the first live stack
trace. To relate this vintage data to original field data either 141-11) if present, must be used or time values from the headers must be used. Its use was historical and primarily for the purposes of
producing shot point maps which could be related to a section. Its use has been discontinued from 01993 and replaced by SHOT which in most cases will be identical to FFID. Exceptions occur when
the line has been merged for acquisition or processing reasons and SHOT numbers have been re-sequenced to obtain a continuous numbering sequence.

The convention used for the SHOT annotation position is the mid-point of the source and the firstactive channel. Therefore the ship antenna position, which is Rig Seismic's firing navigation referencepoint, is corrected to relate to this point for all final navigation data.

Field data polarity is maintained throughout the processing sequence. The convention for AGSOdata is that a compression wave is plotted as negative.

Some data sets may include bathymetry and geophysical data such as magnetics and gravity. These are also corrected to the mid-point location.

Sustainable Management of Coastal Groundwater Resources

The Sustainable Management of Coastal Groundwater Resources (SMCGR) project aims to improve the management of groundwater in coastal dune aquifers, which is used to supply water for coastal communities in the Mid North Coast region.

There is increasing pressure on groundwater resources from expanding urbanisation and tourism in this region, which has made sustainable management of existing groundwater supplies an important issue for coastal communities and councils.

Over extraction from groundwater systems can affect the water available for ecosystems, which may be dependent on shallow groundwater resources. Withdrawal of groundwater resources in excess of the
sustainable yield may also result in fresh water resources being degraded by seawater intrusion or by upcoming from underlying saline water bodies.

Tectonic and sedimentary history of the Argo Abyssal Plain, eastern Indian Ocean

Bathymetric and seismic reflection profiles totalling about 2800 km, and covering about 110 000 km2 of the Argo Abyssal plain, have been analysed. The early emplacement of oceanic crust and volcanic edifices (Late Jurassic and Early Cretaceous) was followed by cooling, and marked subsidence until the Miocene. The principal structural features have been identified as the right-laterally sheared Wombat Graben in the south, the N-S trending Joey Rise in the west, the parallel sediment-filled Joey Graben to its east, a NW-trending eastward tilted and subsided volcanic massif to its east, a NW-trending linear volcanic massif on the old oceanic plate farther east, the deformed and uplifted sediments and basement in the north, and the central basin with 1.2 km thick sediments. The Joey, Wombat and Kivi Grabens are newly identified.  The N- S trending Joey Graben is 400-450 km long, parallel to and east of the Joey Rise, and it is filled with up to 1 km of sediment. Beneath it, the mantle has been identified at depths of 12-15 km and deepening westward. The other two grabens form moats hundreds of metres deep, at the foot of the Australian margin in the south. The right-lateral displacements in the axis of the Wombat Graben reflect the initial shearing and rifting of the thinned crust. The widespread faulting in the basement, and the persistence of some faults upward into sediments as young as early Miocene, indicate that tectonism was marked until then.  The eastern and northern parts of the abyssal plain have been uplifted as they came within the peripheral fore-bulge south of the Sunda Trench.  Five sequences (A-E) overlie the oceanic crust and they have been correlated with the lithology of ODP Site 765 and DSDP Site 261. They probably represent Plio-Pleistocene, upper Miocene-lower Pliocene, middle Miocene, upper Oligocene-lower Miocene and uppermost Jurassic to Lower Cretaceous strata, respectively. The depositional trends in the Mesozoic and Miocene sediments are controlled by basement structure. Isopach maps of the Mesozoic and Cainozoic sediments reveal that their maximum thicknesses are about 0.6-0.8 km and 0.2-0.4 km, respectively, with the bulk of the sediments (calcareous turbidites and claystone) laid down in the Early Cretaceous and the middle Miocene to Pliocene. During the Oligocen e to early Miocene period (37-16 Ma), a remarkable geologic event led to non-deposition or erosion of sediments.
