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). -

Hunting on the rocks down at Gottschalck’s Jetty, & found several varieties of Cominella,a number of which were feeding on a dead Chiton. Several Dromiae, strange brown hairy crabs having their backs covered by a closely-fitting but unattached zoophyte ore sponge; also a couple of Chitonellus Gunni ( ), a genus of Chitonidae in which the plates are very small & narrow & imbedded at intervals along the cartilaginous back of the mollusc. Received a letter from Pulleine to whom I had sent a specimen of the black-faced Artamus which was so abundant a couple of months ago. It is the Masked Wood Swallow (Artamus personatus), a species of periodical occurrence. I have 3 good skins, & 2 eggs. The nest is si placed in similar situations to those of A. sordidus & the construction is pretty much the same, loose twigs with no lining. The male bird has a rusty red breast & is very un- Page 3.

Chapter 21. Fauna of Jetty Piles, Artificial Reefs and Biogenic Surfaces
Chapter 21. Fauna of jetties and artificial reefs CHAPTER 21. FAUNA OF JETTY PILES, ARTIFICIAL REEFS AND BIOGENIC SURFACES ALAN BUTLER C.S.I.R.O. Marine Research, Hobart, Tasmania 7001. Email: [email protected] Figure 1. Piling of Edithburgh jetty showing sponges, ascidians and bryozoans. (CAS) Introduction This chapter is not a comprehensive description or natural history of the fauna of all jetties, artificial reefs and biogenic surfaces in Gulf St Vincent (GSV) and its approaches. It is about studies done on certain jetties, etc., in the Gulf, using them as experimental systems to increase our understanding of the larger ecosystem of which they are a part. I think of the fauna attached to pilings, artificial reefs and biogenic surfaces as a window on that larger system. Pilings have been convenient places to do experiments and make repeated observations. It has to be remembered, however, that the organisms we are studying on such surfaces are part of larger populations. They have dispersive larvae which may travel short to long distances with the currents; they have predators that move about; the assemblage on one jetty is thus connected to assemblages on other jetties and reefs. We can learn a great deal by observations and experiments at the small scale, but ultimately it only makes sense if we can successfully ‘scale up’—understand these habitats in the context of the system in which they are embedded. I say more, at the end, about this ‘scaling up’. Also, the jetties etc. are artificial—a type of substratum that was not present during the millions of years of evolution of these organisms—and are, in various respects, different from their ‘natural’ habitats. -
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. -
Chapter 18. Razor Fish and Scallops
Chapter 18. Razorfish and scallops CHAPTER 18. RAZOR FISH AND SCALLOPS ALAN BUTLER CSIRO Marine and Atmospheric Research, Hobart, Tasmania 7001. Email: [email protected] Figure 1. Razorfish Pinna bicolor near seagrass, Posidonia sp. The individual in foreground shows some recent, rapid growth at the posterior margin of the shell and an epifauna mainly of serpulids but with a gastropod, a few bryozoans, and a small colony of a didemnid ascidian beginning to overgrow the bryozoans. The shell in the background is dead, may have been there for a decade, and has a well-developed epifauna, mainly of bryozoans with a couple of sponge colonies. Introduction This chapter outlines some ecological studies of bivalve molluscs in Gulf St Vincent (GSV) waters. It is eclectic, not attempting to cover all studies of bivalves, but mainly those of several large species—the ‘razor fish’ Pinna bicolor, and the scallops Mimachlamys asperrima and Equichlamys bifrons—which are conspicuous, and have proven instructive not only for understanding the ecology of these sorts of animals (sessile filter-feeders, with broadcast spawning, external fertilisation and a long larval period), but of the dynamics of the Gulf ecosystem and of the relationships between species. A vast amount has been written about the ecology of bivalves worldwide (e.g. Wilbur & Yonge 1964- 1966; Bayne 1976; Yonge & Thompson 1976; Purchon 1977; Wilbur 1983-1988; Suchanek 1985; Ludbrook & Gowlett-Holmes 1989; Beesley et al. 1998), and no attempt is made to summarise it here. 238 Chapter 18.

Jetties, shipwrecks and other artificial reefs. Chapter 16 in: Baker, J.L. (2015) Marine Assets of Yorke Peninsula. Report for Natural Resources - Northern and Yorke / NY NRM Board, South Australia. 16. Jetties, Shipwrecks and Other Artificial Reefs Edithburgh Kleins Point © D. Kinasz © J. Zhang Asset Jetties, Shipwrecks and other Artificial Reefs Description Structures of wood, iron, steel, and other materials, throughout the NY NRM region, ranging from oceanographically exposed through to sheltered locations. Jetties and shipwrecks function as surfaces for attachment of marine plants and attached invertebrates; sheltering and feeding areas for fishes, sharks, rays and invertebrates; and as “fish-attracting” devices, periodically visited by schooling fishes which are attracted to vertical structure. Surrounding sea floor varies according to the location of the jetty or wreck, and includes reef, seagrass, sand, and rubble. There are also two purpose-built artificial reefs in the NY NRM region, constructed of tetrahedon module units, made up vehicle tyres. Main Species Sponges sponges (numerous species, in genera Dysidea, Euryspongia, Darwinella, Aplysilla, Dendrilla, Clathrina and many others) Ascidians / Sea Squirts Red-mouthed Ascidian, Obese Ascidian, and other solitary ascidians / sea squirts Brain Ascidian, and other colonial ascidians Spongy Compound, Leach’s Compound & other compound ascidians Corals gorgonian corals such as Mopsella zimmeri (on current-exposed jetties) soft corals, such as Carijoa (also Drifa sp. on current-exposed jetties) solitary coral Scolymia Bryozoans various species, including various species in Cellaporaria (such as Orange Plate Bryozoan and Nipple Bryozoan) and species in Triphyllozoon (Lace Bryozoans) Gastropod Shells Cowries, Cartrut shell, Triton shells Bivalve Shells Doughboy Scallop, Razorfish Shell, juvenile Native Oyster Jetties, shipwrecks and other artificial reefs. -
Mike Makatron
MIKE MAKATRON Mike Maka was born in the Yorke Peninsula to the large Moloney clan of 12 siblings. Their farm for over 80 years in Arthurton still runs in the family to this day, with two of Mikes Uncles working the land. With a close connection to the Yorke Peninsula, Mike proposes the following concept for Edithburgh. Edithburgh Concept: The Edithburgh concept begins with a wide array of coral sourced from underwater photography of the local jetty, as well as a Striped Pyjama Squid, a Cuttlefish and the magnificent Leafy Sea Dragon. Contrasting the deep blue of the surf in the bottom section, the top of the work features a radiant sunrise backgrounding the White Bellied Sea Eagle and the endangered Far Eastern Curlew in dynamic stages of flight as well as the Troubridge Island lighthouse darting up from the swell. Adorned with a subtle reference to 1856 establishment at the base. Edithburgh Design Concept: (to scale/flat) EDITHBURGH RESPONSE: For the Edithburgh water tower I have chosen to propose a design that celebrates the magnificent marine life beneath Edithburgh Jetty. Rich and buzzing natural hubs like the underwater garden at Edithburgh Jetty are increasingly rare and more essential than ever. Not only is this a bold, colourful and iconic landmark, it’s also one that demonstrates importance for the visibility and appreciation of Yorke Peninsula’s lively sea environment. Not only will the mural locate and reference a unique natural wonder of Edithburgh, the curved surface of the tower itself will also be utilised in visually imitating the cylindrical Edithburgh Jetty pylons that harbour the colourful sea sponges and marine life. -
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. -

Revision of the Monacanthid Fish Genus Brachaluteres
Rec. West. Aust. Mus. 1985, 12 (1): 57-78 Revision of the Monacanthid Fish Genus Brachaluteres J. Barry llutchins* and Roger Swainston* Abstract Four species of the monacanthid genus Brachaluteres are recognised: B. jack sonianus (Quoy and Gaimard) from southern Australia; B. taylori Woods from Queensland, Lord Howe Island, New Guinea and the Marshall Islands; B. ulvarum Jordan and Snyder from Japan; and B. fahaqa Clark and Gohar from the Red Sea. The long accepted name of B. baueri (Richardson) is shown to be ajunior synonym of B. jacksonianus. A key to the species is provided, as well as diagnostic illus trations. Introduction The monacanthid genus Brachaluteres consists of small fishes which are known from shallow inshore waters of several areas in the Indian and Pacific Oceans. They are reasonably common in Australia and Japan, but records for the Marshall Islands, Papua New Guinea, the Maldives and the Red Sea are each based on one to three specimens only. Being poor swimmers, they are usually found on shel tered reefs, in sea grasses or around jetty piles. All members of the genus can greatly inflate their abdomens when in danger, an adaptation which serves to noticeably increase their body size (Figure 1). This feature, together with their cryptic coloration, probably decreases the chances of predation, and therefore compensates for their relatively poor swimming ability. The genus has not been reviewed previously, although species lists and/or species accounts were presented by Gunther (1870), MacIeay (1881), McCulloch, (1929), Fraser-Brunner (1941), Clark and Gohar (1953), Whitley (1964), Woods (1966) and Scott (1969). -
