Australian tidal currents – assessment of a barotropic model (COMPAS v1.3.0 rev6631) with an unstructured grid. David A. Griffin1, Mike Herzfeld1, Mark Hemer1 and Darren Engwirda2 1Oceans and Atmosphere, CSIRO, Hobart, TAS 7000, Australia 2Center for Climate Systems Research, Columbia University, New York City, NY, USA and NASA Goddard Institute for 5 Space Studies, New York City, NY, USA Correspondence to: David Griffin ([email protected]) Abstract. While the variations of tidal range are large and fairly well known across Australia (less than 1 m near Perth but more than 14 m in King Sound), the properties of the tidal currents are not. We describe a new regional model of Australian 10 tides and assess it against a validation dataset comprising tidal height and velocity constituents at 615 tide gauge sites and 95 current meter sites. The model is a barotropic implementation of COMPAS, an unstructured-grid primitive-equation model that is forced at the open boundaries by TPXO9v1. The Mean Absolute value of the Error (MAE) of the modelled M2 height amplitude is 8.8 cm, or 12 % of the 73 cm mean observed amplitude. The MAE of phase (10°), however, is significant, so the M2 Mean Magnitude of Vector Error (MMVE, 18.2 cm) is significantly greater. The Root Sum Square over the 8 major 15 constituents is 26% of the observed amplitude.. We conclude that while the model has skill at height in all regions, there is definitely room for improvement (especially at some specific locations). -
PETROLEUM SYSTEM of the GIPPSLAND BASIN, AUSTRALIA by Michele G
uses science for a changing world PETROLEUM SYSTEM OF THE GIPPSLAND BASIN, AUSTRALIA by Michele G. Bishop1 Open-File Report 99-50-Q 2000 This report is preliminary and has not been reviewed for conformity with the U. S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade names is for descriptive purposes only and does not imply endorsements by the U. S. government. U. S. DEPARTMENT OF THE INTERIOR U. S. GEOLOGICAL SURVEY Consultant, Wyoming PG-783, contracted to USGS, Denver, Colorado FOREWORD This report was prepared as part of the World Energy Project of the U.S. Geological Survey. In the project, the world was divided into 8 regions and 937 geologic provinces. The provinces have been ranked according to the discovered oil and gas volumes within each (Klett and others, 1997). Then, 76 "priority" provinces (exclusive of the U.S. and chosen for their high ranking) and 26 "boutique" provinces (exclusive of the U.S. and chosen for their anticipated petroleum richness or special regional economic importance) were selected for appraisal of oil and gas resources. The petroleum geology of these priority and boutique provinces is described in this series of reports. The purpose of this effort is to aid in assessing the quantities of oil, gas, and natural gas liquids that have the potential to be added to reserves within the next 30 years. These volumes either reside in undiscovered fields whose sizes exceed the stated minimum- field-size cutoff value for the assessment unit (variable, but must be at least 1 million barrels of oil equivalent) or occur as reserve growth of fields already discovered. -
The Impact of Sea-Level Rise on Tidal Characteristics Around Australia Alexander Harker1,2, J
The impact of sea-level rise on tidal characteristics around Australia Alexander Harker1,2, J. A. Mattias Green2, Michael Schindelegger1, and Sophie-Berenice Wilmes2 1Institute of Geodesy and Geoinformation, University of Bonn, Bonn, Germany 2School of Ocean Sciences, Bangor University, Menai Bridge, United Kingdom Correspondence: Alexander Harker ([email protected]) Abstract. An established tidal model, validated for present-day conditions, is used to investigate the effect of large levels of sea-level rise (SLR) on tidal characteristics around Australasia. SLR is implemented through a uniform depth increase across the model domain, with a comparison between the implementation of coastal defences or allowing low-lying land to flood. The complex spatial response of the semi-diurnal M2 constituent does not appear to be linear with the imposed SLR. The most 5 predominant features of this response are the generation of new amphidromic systems within the Gulf of Carpentaria, and large amplitude changes in the Arafura Sea, to the north of Australia, and within embayments along Australia’s north-west coast. Dissipation from M2 notably decreases along north-west Australia, but is enhanced around New Zealand and the island chains to the north. The diurnal constituent, K1, is found to decrease in amplitude in the Gulf of Carpentaria when flooding is allowed. Coastal flooding has a profound impact on the response of tidal amplitudes to SLR by creating local regions of increased tidal 10 dissipation and altering the coastal topography. Our results also highlight the necessity for regional models to use correct open boundary conditions reflecting the global tidal changes in response to SLR. -

June 1946 MEM. NAT. Mus. V1cT., 14, PT. 2, 1946. https://doi.org/10.24199/j.mmv.1946.14.06 THE SUNKLANDS OF PORT PHILLIP BAY AND BASS STRAIT By R. A. Keble, F.G.S., Palaeontologist, National Jiiiseurn of Victoria. Figs. 1-16. (Received for publication 18th l\fay, 1945) The floors of Port Phillip Bay and Bass Strait were formerly portions of a continuous land surface joining Victoria with Tasmania. This land surface was drained by a river system of which the Riv-er Y arra was part, and was intersected by two orogenic ridges, the Bassian and King Island ridges, near its eastern and western margins respectively. \Vith progressive subsidence and eustatic adjustment, these ridges became land bridges and the main route for the migration of the flora and fauna. At present, their former trend is indicated by the chains of islands in Bass Strait and the shallower portions of the Strait. The history of the development of the River Yarra is largely that of the former land surface and the King Island land bridge, and is the main theme for this discussion. The Yarra River was developed, for the most part, during the Pleistocene or Ice Age. In Tasmania, there is direct evidence of the Ice Age in the form of U-shaped valleys, raised beaches, strandlines, and river terraces, but in Victoria the effects of glaciation are less apparent. A correlation of the Victorian with the Tasmanian deposits and land forms, and, incidentally, with the European and American, can only be obtained by ascertaining the conditions of sedimentation and accumulation of such deposits in Victoria, as can be seen at the surface1 or as have been revealed by bores, particularly those on the N epean Peninsula; by observing the succession of river terraces along the Maribyrnong River; and by reconstructing the floor of Port Phillip Bay, King Bay, and Bass Strait, and interpreting the submerged land forms revealed by the bathymetrical contours. -

LEMASSON Ofice de la Recherche Scientijque et Technique Outre-Mer, Centre de Nouméa BATHYMETRY AND TOPOGRAPHY OF THE COR_-L AND TASMAN SEAS The Coral Sea extends between the Solomon Islands on the northeast, New Caledonia and the New Hebrides Islands on the east, and the coast of Queensland on the west while to the south it is limited by the Tasman Sea. To the northwest it communicates with the Arafura Sea by the shallow Torres Strait; at the Solomon Archipelago it opens on to the equatorial zone of the Pacifìc Ocean and comes under the influence of the central and tropical Pacific both in crossing the Archipelago of the New Hebrides and to the south of New Caledonia. The Coral Sea has a mean depth of the order of 2400 m with a maximum of 9140 m in the New Britain Trench. The Tasman Sea is limited to the north by the Coral Sea, to the east by New Zealand, to the west by the coast of New South Wales and to the south by Tasmania; in the south it is largely under the influence of the Antarctic Ocean and in the west under that of the central South Pacific. The maximum depth is 5943 m. BATHYMETRY As is apparent from the most recent bathymetric chart of these oceans (Menard, 1964) they have a complicated structure which is particularly evident in the Coral Sea. -
Wintertime Circulation Off Southeast Australia: Strong Forcing by the East Australian Current John F
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 110, C12012, doi:10.1029/2004JC002855, 2005 Wintertime circulation off southeast Australia: Strong forcing by the East Australian Current John F. Middleton School of Mathematics, University of New South Wales, Sydney, New South Wales, Australia Mauro Cirano Centro de Pesquisa em Geofisica e Geologia, Universidade Federal da Bahia, Salvador, Brazil Received 21 December 2004; revised 18 April 2005; accepted 22 September 2005; published 13 December 2005. [1] Numerical results and observations are used to examine the sub–weather band wintertime circulation off the eastern shelf slope region between Tasmania and Cape Howe. The numerical model is forced using wintertime-averaged atmospheric fluxes of momentum, heat, and freshwater and using transports along open boundaries that are obtained from a global ocean model. The boundary to the north of Cape Howe has a prescribed transport of 17 Sv, which from available observations represents strong forcing by the East Australian Current (EAC). Nonetheless, the model results are in qualitative (and quantitative) agreement with several observational studies. In accord with observations, water within Bass Strait is found to be driven to the east and north with speeds of up to 30 cm sÀ1 off the southeast Victorian coast. The water is colder and denser than that found farther offshore, which is associated with the southward flowing (warm) EAC. In agreement with observations the density difference between the two water masses is about 0.6 kg mÀ3 and leads to a cascade of dense Bass Strait water to depths of 300 m and as a plume that extends 5–10 km in the cross-shelf direction.
