Plan Summary Rev 2 1 INTRODUCTION 1.1 Background Asset Energy Pty Ltd, as the Titleholder, proposes to undertake a high resolution two-dimensional (2D) seismic survey located in PEP -11 offshore Commonwealth waters, New South Wales (NSW). The survey will be predominantly undertaken within an area of 12.25 square kilometres (km2) plus a single 2D tie line, to the surface location of the exploration well: New Seaclem-1, of ~50km length. The duration of the survey is between 3 to 4 days and will be undertaken using a purpose-built survey vessel equipped with the necessary hardware to conduct a seismic acquisition survey. For the purposes of this Environment Plan, it is assumed that the survey vessel will be the Pacific Conquest (IMO 8600741). Seismic and drilling operations have previously been undertaken by Asset Energy in PEP-11 in the vicinity of the proposed survey area, the most recent offshore drilling campaign was in 2010. The purpose of this 2018 campaign is to further the understanding of the shallow sub-surface geology and the potential drilling hazards over a prospect in the area of interest through the acquisition of high resolution geophysical data (high-resolution 2D seismic survey). 1.2 EP Nominated Liaison Person Asset Energy’s contact details and nominated contact person (with respect to this EP Summary) are as follows: Tobias Foster Director Asset Energy Pty Ltd Suite 2, Level 3, 1111 Hay Street, West Perth, Western Australia 6005 Telephone Number: +61 (0)8 9200 6190 Mobile Number: +61 (0) 431 040 120 Email: [email protected] Website: www.adventenergy.com.au 7 Asset Energy Pty Ltd Baleen 2D HR Seismic Survey Environment Plan Summary Rev 2 2 ACTIVITY DESCRIPTION 2.1 Location The seismic survey will be located entirely within Permit Area PEP-11 – offshore Sydney Basin (Figure 2.1), NSW.

Belkin and Peter C. Cornillon Abstract. Oceanic fronts shape marine ecosystems; therefore front mapping and characterization is one of the most important aspects of physical oceanography. Here we report on the first effort to map and describe all major fronts in the World Ocean’s Large Marine Ecosystems (LMEs). Apart from a geographical review, these fronts are classified according to their origin and physical mechanisms that maintain them. This first-ever zero-order pattern of the LME fronts is based on a unique global frontal data base assembled at the University of Rhode Island. Thermal fronts were automatically derived from 12 years (1985-1996) of twice-daily satellite 9-km resolution global AVHRR SST fields with the Cayula-Cornillon front detection algorithm. These frontal maps serve as guidance in using hydrographic data to explore subsurface thermohaline fronts, whose surface thermal signatures have been mapped from space. Our most recent study of chlorophyll fronts in the Northwest Atlantic from high-resolution 1-km data (Belkin and O’Reilly, 2007) revealed a close spatial association between chlorophyll fronts and SST fronts, suggesting causative links between these two types of fronts.

  • The Genome of the Gulf Pipefish Enables Understanding of Evolutionary Innovations C
    Small et al. Genome Biology (2016) 17:258 DOI 10.1186/s13059-016-1126-6 RESEARCH Open Access The genome of the Gulf pipefish enables understanding of evolutionary innovations C. M. Small1†, S. Bassham1†, J. Catchen1,2†, A. Amores3, A. M. Fuiten1, R. S. Brown1,4, A. G. Jones5 and W. A. Cresko1* Abstract Background: Evolutionary origins of derived morphologies ultimately stem from changes in protein structure, gene regulation, and gene content. A well-assembled, annotated reference genome is a central resource for pursuing these molecular phenomena underlying phenotypic evolution. We explored the genome of the Gulf pipefish (Syngnathus scovelli), which belongs to family Syngnathidae (pipefishes, seahorses, and seadragons). These fishes have dramatically derived bodies and a remarkable novelty among vertebrates, the male brood pouch. Results: We produce a reference genome, condensed into chromosomes, for the Gulf pipefish. Gene losses and other changes have occurred in pipefish hox and dlx clusters and in the tbx and pitx gene families, candidate mechanisms for the evolution of syngnathid traits, including an elongated axis and the loss of ribs, pelvic fins, and teeth. We measure gene expression changes in pregnant versus non-pregnant brood pouch tissue and characterize the genomic organization of duplicated metalloprotease genes (patristacins) recruited into the function of this novel structure. Phylogenetic inference using ultraconserved sequences provides an alternative hypothesis for the relationship between orders Syngnathiformes and Scombriformes. Comparisons of chromosome structure among percomorphs show that chromosome number in a pipefish ancestor became reduced via chromosomal fusions. Conclusions: The collected findings from this first syngnathid reference genome open a window into the genomic underpinnings of highly derived morphologies, demonstrating that de novo production of high quality and useful reference genomes is within reach of even small research groups.

  • Future Changes to the Upper Ocean Western Boundary Currents Across Two Generations of Climate Models Alex Sen Gupta1,2,3*, Annette Stellema1,2,3, Gabriel M
    www.nature.com/scientificreports OPEN Future changes to the upper ocean Western Boundary Currents across two generations of climate models Alex Sen Gupta1,2,3*, Annette Stellema1,2,3, Gabriel M. Pontes4, Andréa S. Taschetto1,2, Adriana Vergés3,5 & Vincent Rossi6 Western Boundary Currents (WBCs) are important for the oceanic transport of heat, dissolved gases and nutrients. They can afect regional climate and strongly infuence the dispersion and distribution of marine species. Using state-of-the-art climate models from the latest and previous Climate Model Intercomparison Projects, we evaluate upper ocean circulation and examine future projections, focusing on subtropical and low-latitude WBCs. Despite their coarse resolution, climate models successfully reproduce most large-scale circulation features with ensemble mean transports typically within the range of observational uncertainty, although there is often a large spread across the models and some currents are systematically too strong or weak. Despite considerable diferences in model structure, resolution and parameterisations, many currents show highly consistent projected changes across the models. For example, the East Australian Current, Brazil Current and Agulhas Current extensions are projected to intensify, while the Gulf Stream, Indonesian Throughfow and Agulhas Current are projected to weaken. Intermodel diferences in most future circulation changes can be explained in part by projected changes in the large-scale surface winds. In moving to the latest model generation, despite structural model advancements, we fnd little systematic improvement in the simulation of ocean transports nor major diferences in the projected changes. Anthropogenic climate change manifests as increases in surface temperature and sea level, rainfall distribution changes and increasing frequency and intensity of certain extreme events1.

Some oceanic realms, however, remain poorly studied. We document U37 index data for two sediment cores retrieved from the South Tasman Sea, one west of New Zealand (SO136-GC3) and the other southeast of Tasmania (FR1/94-GC3), extending back 280 kyr BP for the former and 460 kyr BP for the latter. High climatic sensitivity on orbital time scales is observed at both locations, particularly west of New Zealand, where typical glacial/interglacial SST amplitudes always span more than 7 °C. Southeast of Tasmania, SST amplitudes are lower in amplitude (4.3 to 6.9 °C) with the exception of Termination IV, which involved a SST change over 8 °C.

  • Chapter 36D. South Pacific Ocean
    Chapter 36D. South Pacific Ocean Contributors: Karen Evans (lead author), Nic Bax (convener), Patricio Bernal (Lead member), Marilú Bouchon Corrales, Martin Cryer, Günter Försterra, Carlos F. Gaymer, Vreni Häussermann, and Jake Rice (Co-Lead member and Editor Part VI Biodiversity) 1. Introduction The Pacific Ocean is the Earth’s largest ocean, covering one-third of the world’s surface. This huge expanse of ocean supports the most extensive and diverse coral reefs in the world (Burke et al., 2011), the largest commercial fishery (FAO, 2014), the most and deepest oceanic trenches (General Bathymetric Chart of the Oceans, available at www.gebco.net), the largest upwelling system (Spalding et al., 2012), the healthiest and, in some cases, largest remaining populations of many globally rare and threatened species, including marine mammals, seabirds and marine reptiles (Tittensor et al., 2010). The South Pacific Ocean surrounds and is bordered by 23 countries and territories (for the purpose of this chapter, countries west of Papua New Guinea are not considered to be part of the South Pacific), which range in size from small atolls (e.g., Nauru) to continents (South America, Australia). Associated populations of each of the countries and territories range from less than 10,000 (Tokelau, Nauru, Tuvalu) to nearly 30.5 million (Peru; Population Estimates and Projections, World Bank Group, accessed at http://data.worldbank.org/data-catalog/population-projection-tables, August 2014). Most of the tropical and sub-tropical western and central South Pacific Ocean is contained within exclusive economic zones (EEZs), whereas vast expanses of temperate waters are associated with high seas areas (Figure 1).

  • Decadal Changes in the East Australian Current System – the Relationship to Changes in the South Pacific Gyre
    Decadal Changes in the East Australian Current system – the relationship to changes in the South Pacific Gyre. Ken R. Ridgway1 and Katy L. Hill2 1 Centre for Australian Weather and Climate Research, CSIRO Marine and Atmospheric Research, GPO Box 1538, Hobart 7001, Tasmania, Australia 2 Integrated Marine Observing System, University of Tasmania, Private Bag 1538, Hobart 7001, Tasmania, Australia. E-mail: [email protected] The Tasman Box sections are used to determine a 20-year time series of the volume transport associated with each of the main inflows and outflows within the South Pacific boundary current system. Three eddy-resolving XBT sections enclosing the Tasman Sea make up the Tasman Box. Each of the sections has been regularly sampled at eddy-resolving scales on precisely repeating locations in order to separate temporal from spatial variability of properties. The quarterly sampling of the XBT transects is supplemented by estimates of the geostrophic transport from satellite altimetry. The method is validated by comparison with independent CTD sections. The transport time series (relative to a 2000-m level) resolve the full suite of temporal signals from eddy scale, seasonal, interannnual to decadal and are used to investigate the nature and mechanism of decadal variability in the East Australian Current (EAC) system and south Pacific subtropical gyre. The main EAC flow separates into an eastward component (Tasman Front) and a poleward flow (EAC Extension) just north of Sydney. At decadal timescales these components are anti-correlated. This decadal variation confirms the EAC response to a spin-up of the South Pacific circulation forced by changes in the basin-wide winds and matches the changes in oceanic properties observed in the Tasman Sea.

Maps in A4 size are preferred. You must also attach a map(s)/plan(s) showing the location and boundaries of the project area in respect to any features identified in 3.1 & 3.2, as well as the extent of any freehold, leasehold or other tenure identified in 3.3(i). 1.1 Short description Use 2 or 3 sentences to uniquely identify the proposed action and its location. Supercolonies of the invasive yellow crazy ant Anoplolepis gracilipes (YCA) are a major and on- going threat to biodiversity values on Christmas Island, especially to red land crabs Gecarcoidea natalis and robber crabs Birgus latro. To date, the management of YCA supercolonies has depended on surveillance, monitoring and control using toxic bait (mostly fipronil), particularly through aerial baiting programs in 2002, 2009 and 2012. While this program has been very effective in suppressing YCA supercolonies and there are encouraging signs of recovery in many treated areas, new supercolonies continue to form. There is widespread concern for the sustainability of this program in terms of its expense,
