<div>The Abbot Point to Hydrographers Passage bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the RV Escape during the period 6 Oct 2020 – 16 Mar 2021. This was a contracted survey conducted for the Australian Hydrographic Office by iXblue Pty Ltd as part of the Hydroscheme Industry Partnership Program. The survey area encompases a section of Two-Way Route from Abbot Point through Hydrographers Passage QLD. Bathymetry data was acquired using a Kongsberg EM 2040, and processed using QPS QINSy. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.</div><div>This dataset is not to be used for navigational purposes.</div>

GEBCO Bathymetric contours coded with values of metres below sea level. The original Arcinfo dataset resides in the UNIX corporate storage area at /d/geo/store/data/marine/bathymetry

Colour and greyscale images have been generated at several resolutions (pixel sizes 860m, 2km, 4km, 10km) and these are digital pictoral representations of the 30 arc second bathymetric point grid of the Australian region released in 1998 and a sub sampled version of the GEODATA NINE SECOND DEM, 1996 which is copyright, Commonwealth of Australia, AUSLIG. These images depict the continental margin morphology, and are suitable for use in diverse applications, such as resource management, oceanographic modelling and fisheries studies. The original gridded bathymetry model for the Australian continental margin was generated from 14,000,000 data points gathered from numerous data sources and compiled by Cameron Buchanan at the Australian Geological Survey Organisation, as part of the Continental Margins Program. The database is a 30-arc-second model that can display undersea features as small as 900 metres. The model has been compiled over several years from hundreds of marine surveys. It includes data acquired by industry and foreign agencies, and from over 200 days of modern deep-water seafloor swath-mapping surveys. In some areas not covered by marine surveys, it incorporates bathymetry data derived from satellite measurements. The raw ASCII data is available on CD Titled "Bathymetric 30 arc second grid of the Australian Region" (1998) from the AGSO sales centre. NOTE : This product does not contain topography.

This CD contains three movies over computer generated surfaces taking you on a path at an upper atmosphere altitude following the Australian coastline. The surface images were generated from actual geophysical measurements, but the vertical scale has been enhanced and colours chosen for visual impact.

This cross agency report, highlights the areas of the central NSW continental slope prone to sediment mass wasting over time. It includes the critical factors which contribute to slope failure including basement geometry, angle of slope and thickness of overlying sediments. Evidence of slope failure are observed through: surficial tension cracks; creep features; faulting; redistribution of sediments, multiple relict slides on the sea floor and erosional surface scars.

The data currently held for bathymetry has been extracted from the GEBCO (General Bathymetric Chart of the Oceans) produced by the Natural Environment Research Council (UK).

A 3.30 minute movie that has the viewer flying around Australia to 6 release areas: Gippsland Basin, Money Shoal Basin, Bonaparte Basin, Canning Basin, Browse Basin and Carnarvon Basin. The movie also stops at each release area to view, in detail, the: International/State seafloor boundaries; oil and gas fields; release areas; Basin/sub-basin outlines. Topographic markers are also shown, where possible.

A 3.30 minute movie, (based on the movie used in the 2007 Acreage Release Product CD - Geocat No. 65159), that has the viewer flying around Australia to 6 release areas: Gippsland Basin, Money Shoal Basin, Bonaparte Basin, Canning Basin, Browse Basin and Carnarvon Basin. The movie also stops at each release area to view, in detail, the: International/State seafloor boundaries; oil and gas fields; release areas; Basin/sub-basin outlines. Topographic markers are also shown, where possible. This movie has the addition of MUSIC.
