Richard Sellers is the executive director of minerals and energy in the Northern Territory and has extensive experience with the management of natural resources and working specifically with business, regional and Indigenous groups on development programs. He has previously held roles as Executive Director—Fisheries and Director—Legal and Policy in the former Northern Territory Department of Primary Industry and Fisheries. This paper covers the annual presentation of exploration activity in onshore and coastal waters in Australia’s states and the Northern Territory. Included is a summary of upstream petroleum acreage opportunities for 2009 in the states and Northern Territory as well as geothermal energy exploration opportunities. While there have been increasing levels of exploration in recent years, there are large areas that remain under explored and the opportunity for future discoveries remains. State and the Northern Territory Governments have continued to undertake initiatives to attract and facilitate accelerated exploration and promote nationally and internationally these opportunities in frontier and production areas.

This is the annual presentation of what’s happening in onshore and coastal waters exploration in Australia’s states and the Northern Territory. The main focus of these jurisdictions’ annual report at the APPEA conference is upstream petroleum acreage opportunities. Exploration for geothermal energy resources will also be covered. There are many and diverse exploration opportunities in onshore frontier and producing Australian basins available for explorers in 2008, including geothermal energy exploration opportunities. The number of onshore Australian acreage applications has been steadily increasing in recent years and this has resulted in higher levels of drilling and seismic acquisition, but large areas remain untouched by modern exploration. Australian state governments continue initiatives to encourage exploration to realise their natural resource endowments including: pre-competitive basin studies; speedy and cost-effective provision of digital exploration data; provision of effective land access regimes; transparent regulatory regimes; internationally competitive royalty regimes; and, promotion of acreage releases nationally and internationally.

Some factors that may affect the aerial counts of dugongs, dolphins and turtles were examined experimentally. Tidal influence did not affect the counts of dugongs or dolphins, but those of turtles increased around high tide. A combined doubling of survey altitude and transect width reduced observed density of all three classes of animals by 50%. The counts of four observers did not differ significantly, but further data counsel caution. Overcast weather depressed counts of dugongs and turtles. Dolphin counts were affected by water surface condition, counts being lowest in choppy seas. A mark-recapture model was used on tandem observations to derive correction factors for groups of animals missed on the surface of a transect. Observers missed between 33% and 75% of dugong groups on the surface, the probability of detection decreasing with increased survey altitude and transect width. A similar range and pattern of probabilities was found for dolphins and turtles. Dugongs were censused in the coastal waters of the Northern Territory between the Daly River and Millingimbi in December 1983, an area of 28 746 km*2. Sampling intensity was 7.6%. A minimum population of 2953 � 530 (standard error) was estimated, an overall relative density of 0.11 � 0.02 km-2. A theoretical correction for submerged dugongs not seen yielded a total population estimate of 38 000, an overall density of 1.46 km-2. The distribution of dugongs in the survey area was patchy, the highest densities being associated with shallow coastal waters, sheltered bays, and large islands.

Exploration Activity

The petroleum industry in Australia is going through a major development phase with export LNG projects under construction on both the east and west coasts. Initial exploration for shale and tight gas has opened up new plays as well as increasing interest in many sedimentary basins that have been overlooked. Access to land onshore in Australia for petroleum exploration is, in some States, through a formal release process by the relevant jurisdiction. This is a compilation of material supplied by the States and Northern Territory in relation to land being made available onshore for petroleum exploration. Not all jurisdictions have new acreage available for exploration. In these cases, new initiatives being undertaken that directly relate to accessing land for exploration or the present state of exploration activity will be highlighted. Land that is being made available for exploration will generally be accompanied by information regarding its geological setting and petroleum potential. Previous exploration activity may be in summaries, including information in relation to the amount of pre-existing data available to future explorers. Exploration opportunities may include conventional and unconventional targets. The review of the areas may also include maps and sections related to the land being made available.

High Concentrations

Analysis of mercury in muscle tissue of four species of carcharhinid shark (genus Carcharhinus) and three species of hammerhead shark (genus Sphyrna) from coastal waters of the Northern Territory has indicated that each of the species studied accumulates relatively high concentrations of mercury. Maximum observed concentrations in all species except C. sorrah (Valenciennes) exceeded 1.5 mg kg-1. Concentrations greater than 4 mg kg-1 were recorded in C. amblyrhynchoides (Whitley), S. lewini (Griffith & Smith) and S. mokarran (Ruppell). Mercury concentration was highly dependent on shark size and increased more or less exponentially with length. Apart from S. lewini and S. mokarran, there were significant differences between length-mercury relationships for males and females of each species. At a given length, males tended to have accumulated higher concentrations of mercury than females. With the exception of C. sorrah, weighted mean concentrations of mercury for each species exceeded the current National Health and Medical Research Council standard for mercury of 0.5 mg kg-1. Implications of possible management based on mercury standards are considered using information available for C. limbatus (Valenciennes) and C. sorrah.

Peter Green is the Geoscience Manager: Energy Geoscience in the Geological Survey Queensland and has extensive experience in basin studies, geoscience and the development of petroleum regulation in Queensland. This paper provides a summary of the land releases for petroleum exploration for onshore areas and coastal waters of Australia for 2010. The summaries include upstream petroleum acreage opportunities for the states and the Northern Territory, and geothermal energy exploration opportunities. The rise in interest in export liquefied natural gas projects has ensured petroleum exploration and production has remained strong. Interest in acquiring petroleum acreage to explore for both conventional and non-conventional plays remains high. Australian state and the Northern Territory governments continue to provide access to land and promotional opportunities for companies to undertake exploration and development of our petroleum resources. Acreage on offer provides a mix of exploration opportunities from conventional oil and gas through to the unconventional plays such as shale gas and tight gas. This change in acreage on offer reflects the changing nature of the onshore petroleum industry in Australia.

The sea skaters, genus Halobates Eschscholtz, include the only known oceanic insects, although most species of Halobates are found in sheltered coastal waters. The present paper deals with the 11 species known from Australian waters, divided into two subgenera, Hilliella China and Halobates s. str., and the latter into 5 species-groups. Characters found useful in forming these species-groups include: interocular width of head, head colour markings, relative lengths of fore tarsal segments, mesotibio-tarsal hair fringe, structure of male genital segments, and vesical armature. The cladistic relationships among species and species-groups are analysed and discussed. A key to the species of Australian Halobates is provided. All species endemic to Australia are redescribed and their distribution recorded and mapped. Taxonomic and distributional notes are given for the remaining species. H. (Hilliella) lannae is described as new from the Northern Territory, and the synonymies H. australiensis Malipatil (= H. hayanus White) and H. ashrnorensis Malipatil (= H. princeps White) are verified. Finally, we discuss the ecological diversity and zoogeography of Australian sea skaters.

AbstractThe existence of collective guilt and its influence on pro-social behaviours was investigated in the context of Indigenous and Non-Indigenous reconciliation in Australia. After the presentation of one of three (negative, positive, ambiguous) one-page Australian histories, 80 psychology undergraduates (47 females) from the Northern Territory University, aged from 18-50 years, indicated their level of national identity, perceived in-group variability, feelings of collective guilt, and how participants and the government should compensate Indigenous groups. Participants were also shown an internet petition, a ‘Sorry list’ apologising to Indigenous Australians, to which they could add their name. Perceptions of in-group variability, collective guilt, and out-group compensation were found to be dependent on participants' level of national identity. In order to facilitate reconciliation, the present data indicate psychographic segmentation of the Australian population, in order to tailor specific reconciliation information to these groups.

Harmful algal blooms (HABs) are known to produce lipophilic marine biotoxins (LMTs) such as okadaic acid (OA) (and its analogues dinophysistoxins (DTXs)), yessotoxins (YTXs), pectenotoxins (PTXs), and azaspiracids (AZAs), all of which can accumulate in bivalve mollusks and exert noxious effects on humans. Health regulations indicate a limit up to 160 µg/kg for OA/DTXs, PTXs or AZAs, and 3.75 mg/kg for YTXs.Argopecten purpuratus is one of the most important commercial marine products exploited in Perú. Despite its importance and the periodic reports of the presence of HABs in Peruvian coastal waters, the lack of information regarding potential contamination by LMTs is noteworthy.In this work, we report a study performed with 115 samples of A. purpuratus collected between November 2013 and March 2015 from 18 scallop production areas distributed along the Peruvian coast in search of LMTs. To magnify positive results, the hepatopancreas tissue was analyzed by an LC-MS/MS method implemented to quantify OA, YTX, AZA-1, and PTX-2. Baseline separation was achieved in 19 min. The method showed satisfactory linearity (R 2 > 0.997), precision (coefficient of variation < 15 %), and limit of quantification (0.155-0.479 ng/mL). The study revealed the presence of YTX in 72 samples and of PTX-2 in 17 samples, with both biotoxins found at concentrations below the regulatory limits. Free OA and AZA-1 were not detected in any scallop sample. This atypical profile, presence of PTX-2 in the absence of OA, has been previously reported and may be linked to presence of the dinoflagellate D. acuminata . The production of YTX could be associated to the phytoplankton G. spinifera and P. reticulatum .This is the first systematic assessment of the four groups of LMTs in shellfish from Peruvian coastal waters. The results attained suggest low prevalence of marine biotoxins in Peruvian bay scallops yet support the necessity of future surveillance and analysis of LMTs in Perú.
