Seven new species of cope pods associated with marine invertebrates are described from the Great Barrier Reef, Australia. They are Panjakus bidentis from the scleractinian Pocillopora verrucosa (Ellis and Solander), Scyphuliger humesi, S. vicinus and S. placidus from the scleractinian Acropora squarrosa (Ehrenberg), Doridicola parapatulus from the nudibranch Glossodoris atromarginata (Cuvier), Ruhtra germinata from an unidentified alcyonacean coral, and Collocheres oribullatus from the crinoid Comanthina belli (Carpenter).

This study explores the geographic characteristics of ecotour resources in Oceania based on the concept of ecotourism along with global education and investigates the global educational applications of eco-resources through a field survey of the Australian Cairns region. The field survey areas are the Green Island within the Great Barrier Reef, Barron Gorge National Park, the Australian Butterfly Sanctuary in Cairns, and the Tjabukai Aboriginal Cultural Park. This case study of the Cairns region is applicable to global education in these aspects: The underwater Observatory and Glass bottom boat in Green Island is used in efficient exploration of ocean ecology; Barron Gorge National Park provides an excellent forest tour with a well-made track, detailed directory, and trained park rangers; the old industrial trains are being recycled for tourism uses; the Australian Butterfly Sanctuary provides various language interpretations and experts to help further visitor's understanding of the surrounding eco-resources; The Aboriginal Cultural Park also utilizes a special program that helps people understand their culture.

International law provides for fundamental navigational rights called the right of transit passage in international straits as defined by UNCLOS. However, the Australian government published Marine Notice 8/2006 and the associated Part 54 of Australian Marine Orders which requires ships transiting the Torres Strait to engage the services of a pilot and imposes significant penalties for non-compliance on the basis of the IMO MEPC 133(53) which is just a resolution as a recommendation. This paper aims to study legal aspects in UNCLOS on the pilotage in the Torres Strait following the extension of the Great Barrier Reef PSSA neighbouring Australia.

When tsunami waves propagate across open ocean they are steered by Coriolis force and refraction due to gentle gradients in the bathymetry on scales longer than the wavelength. When the wave encounters steep gradients at the edges of continental shelves and at the coast, the wave becomes non-linear and conservation of momentum produces squirts of surface current at the head of submerged canyons and in coastal bays. HF coastal ocean radar is well-conditioned to observe the current bursts at the edge of the continental shelf and give a warning of 40 minutes to 2 hours when the shelf is 50-200km wide. The period of tsunami waves is invariant over changes in bathymetry and is in the range 2-30 minutes. Wavelengths for tsunamis (in 500-3000 m depth) are in the range 8.5 to over 200 km and on a shelf where the depth is about 50 m (as in the Great Barrier Reef) the wavelengths are in the range 2.5 - 30 km. It is shown that the phased array HF ocean surface radar being deployed in the Great Barrier Reef (GBR) and operating in a routine way for mapping surface currents, can resolve surface current squirts from tsunamis in the wave period range 20-30 minutes and in the wavelength range greater than about 6 km. There is a trade-off between resolution of surface current speed and time resolution. If the radar is actively managed with automatic intervention during a tsunami alert period (triggered from the global seismic network) then it is estimated that the time resolution of the GBR radar may be reduced to about 2 minutes, which corresponds to a capability to detect tsunamis at the shelf edge in the period range 5-30 minutes. It is estimated that the lower limit of squirt velocity detection at the shelf edge would correspond to a tsunami with water elevation of less than 5 cm in the open ocean. This means that the GBR HF radar is well-conditioned for use as a monitor of small and medium scale tsunamis, and has the potential to contribute to the understanding of tsunami genesis research.

While much in the field of public management has emphasized the importance of nonprofit advocacy activities in policy and decision-making procedures, few have considered the relevance and impact of leading actors on structuring diverse patterns of information sharing and communication through social media. Building nonprofit advocacy is a complicated process for a single organization to undertake, but social media applications such as Facebook and Twitter have facilitated nonprofit organizations and stakeholders to effectively share information and communicate with each other for identifying their mission as it relates to environmental issues. By analyzing the Australian Marine Conservation Society's (AMCS) Twitter network data from the period 1 April to 20 April, 2013, this research discovered diverse patterns in nonprofit advocacy by leading actors in building advocacy. Based on the webometrics approach, analysis results show that nonprofit advocacy through social media is structured by dynamic information flows and intercommunications among participants and followers of the AMCS. Also, the findings indicate that the news media and international and domestic nonprofit organizations have a leading role in building nonprofit advocacy by clustering with their followers.
