Four legs (two on each side of the jetty) were attached to two of Arachna’s decks and the other four legs were attached to the other two decks. Close inspection of the images shows that two of the four legs on one side of the jetty support two decks set close to the side of the jetty, and the other two legs on that side of the jetty support two other decks offset about 1 metre from the jetty. On the other side of the jetty, the legs and decks were positioned in a similar (but opposite) manner. Restoration of Grange Jetty The Grange jetty was refurbished in the latter half of 2014 by Davey Hydraulics from Port Victoria on Yorke Peninsula. The refurbishment included installation of new steel piles alongside the old wooden piles, and replacement of the jetty decking and timber structural elements (girders, crossheads, fishplates, bracings, kerbing and handrails). The lighting system was also replaced, as well as the shelter near the seaward end of the jetty. According to the SA Department of Planning, Transport and Infrastructure, cost of the restoration was $1.8 million. Work began on the 300-metre long jetty in June and it re-opened in early December After a section of the jetty had been refurbished, 2014. Arachna moved shoreward. The length of each step in the shoreward ‘walk’ was the distance between successive jetty pylons. The process of moving involved raising four legs off the seafloor (two legs on each side of the jetty). Then the two decks to which those legs were attached moved shoreward and the legs were lowered back to the seafloor. The other pair of legs from each side of the jetty were then raised and the two decks to which they were attached moved shoreward to be above the decks that had already been moved, and then those four legs were lowered. When Arachna had been repositioned, a work platform was swung out on either side of the jetty, and the shoreward For the restoration, Davey Hydraulics utilised a section of jetty between the next two pylons was green machine on the jetty.

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).

  • 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.

The impact of sea-level rise on tidal characteristics around Australasia Alexander Harker1,2, J.A. Mattias Green2, and Michael Schindelegger1 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 coastal boundary being treated as impenetrable or allowing low-lying land to flood. The complex spatial response of the semi-diurnal constituents, M2 and S2, is broadly similar, with the magnitude of 5 M2’s response being greater. The most predominant features of this response are large amplitude changes in the Arafura Sea and within embayments along Australia’s north-west coast, and the generation of new amphidromic systems within the Gulf of Carpentaria and south of Papua, once water depth across the domain is increased by 3 and 7 m respectively. Dissipation from M2 increases around the islands in the north of the Sahul shelf region and around coastal features along north Australia, leading to a notable drop in dissipation along Eighty Mile Beach. The diurnal constituent, K1, is found to be amplified within the Gulf 10 of Carpentaria, indicating a possible change of resonance properties of the gulf.

    AUSTRALIAN JOINT COPYING PROJECT CAPTAIN MATTHEW FLINDERS Papers, 1801-12 Reel M444 The National Archives Kew, Richmond Surrey TW9 4DU National Library of Australia State Library of New South Wales Filmed: 1960 BIOGRAPHICAL NOTE Matthew Flinders (1774-1814) was born in Donington, Lincolnshire. He entered the Royal Navy in 1789 and in 1791 made his first visit to the Pacific, serving as a midshipman on HMS Providence under William Bligh. In 1795 he sailed to New South Wales on HMS Reliance and, with George Bass, explored the coast south of Sydney. In 1798-99 he and Bass explored Bass Strait and made the first circumnavigation of Van Diemen’s Land. He returned to England in 1800. In 1801 Flinders was promoted to the rank of commander and given command of a sloop, HMS Investigator . He received orders from the Admiralty to explore the unknown southern coast of Australia. He reached Cape Leeuwin in December 1801 and sailing eastwards he charted the Great Australia Bight, Spencer’s Gulf, St Vincent’s Gulf, Kangaroo Island, and Encounter Bay, where he met the French explorer Nicolas Baudin. He explored Port Phillip Bay before reaching Sydney in May 1802. In July 1802 Flinders resumed the survey, sailing north to Cape York and the Gulf of Carpentaria. He found that the Investigator was in a very poor state and was forced to abandon the survey, but he was able to return by way of the western coast and thereby complete the circumnavigation of Australia. He reached Sydney in June 1803. In August 1803 Flinders sailed as a passenger on HMS Porpoise, but the ship was wrecked on the Great Barrier Reef.

More accurate mapping of seagrasses is imperative for their sustainability but is hindered by the lack of data on reflectance spectra representing the optical signatures of individual species. Objectives of this study are: (1) To determine distinct characteristics of spectral profiles for sand versus three temperate seagrasses (Posidonia, Amphibolis, and Heterozostera); (2) to evaluate the most efficient derivative analysis method of spectral reflectance
