The distribution of temperature, salinity, density, dissolved oxygen, phosphate, silicate, and nitrate to 2000 m depth, and phytoplankton to 150 m depth is described in the region of an anticyclonic mesoscale eddy located in the Tasman Sea. Vertical discontinuities in the hydrological properties showed that the eddy had entrained several surrounding water types at the surface and at depths of up to 500 m. In particular, Bass Strait water normally found among the slope waters along the New South Wales coast was entrained by the eddy and transported to positions 200 km from the coast. The temperature and salinity of the eddy appeared to have been increased below the core of the eddy at depths of 300-600 m. due to the entrainment of and mixing with Bass Strait water. The distribution of density, oxygen, nutrients and phytoplankton in the central portion of the eddy between 60 and 240 m depth showed differences between adjoining positions which were attributed to vertical water movements within the eddy core. These movements appeared to be responsible for increases of phytoplankton biomass within the eddy, of up to 10 times that of the surrounding ocean.

Cubiceps baxteri McCulloch 1923 was described based on a single, imperfect (devoid of a tail) stranded specimen collected from a beach in Lord Howe Island, Tasman Sea. Though C. baxteri was reported as a widely distributed tropical species (Butler 1979), it was mainly a result of its incorrect identification (see Agafonova 1994; Stewart and Last 2015). The distribution of C. baxteri is reported to be restricted to the Pacific Ocean, from Japan and eastwards to Baja California (Mexico), southwards to the Hawaiian Islands, New South Wales (Australia), and Lord Howe Island (Tasman Sea) to the Southern parts of Chile (Eschmeyer et al. 2017; Mundy 2005; Agafonova 1994).

ABSTRACT Two subspecies of blue whale occur in Australian waters, (1) the pygmy blue whale (Balaenoptera musculus brevicauda) and (2) the Antarctic blue whale (Balaenoptera musculus intermedia). Understanding blue whale presence in Australian waters is critical to ensuring Australia’s protection of these marine mammals as both subspecies were heavily exploited during historical whaling. This short note documents pygmy blue whale sightings in New South Wales waters over the last 18 years. Observations were opportunistically made via citizen science and verified by scientists. Sightings in this note contribute to our limited knowledge of pygmy blue whale distribution along the east coast of Australia and may help understand the migratory movements of New Zealand pygmy blue whales off Australia and in the Tasman Sea. Overall, information presented in this note contributes to Australia’s national and international conservation efforts to protecting blue whales as a migratory and threatened species.

Core Features

This paper explores the nature of relations between public officials and community workers, drawing on empirical data from a study on Indigenous patrols in New South Wales, Australia. Patrol workers interact with public officials from various state entities who are tasked with overseeing funding, carrying out evaluations and, to varying degrees, monitoring the ‘effectiveness’ of local patrol operations. These interactions illuminate several issues regarding the ways in which knowledge about patrols is created, contested and communicated between Indigenous and non-Indigenous domains. The emergent patterns of these relations can be described as ‘seagull syndrome’, which involves the privileging of some types of knowledge over others in decision-making regarding Indigenous affairs, often with disastrous consequences for Indigenous organisations and communities. The paper documents the core features of seagull syndrome with respect to the discrete practices, everyday decision-making and mundane communication between public officials and patrol workers in New South Wales. It considers the implications of seagull syndrome for policy-makers and academics working in the Indigenous justice space and suggests ways to resist or challenge this tendency

<em>This lecture is given in tribute to Tony Lee. That is only fitting. He is a scholar of international significance and he was personally responsible for much of the core statutory law reform in this State on the subjects of Trusts and Succession Law. Not long after the High Court’s decision in Farah Constructions Pty Ltd v Say-Dee Pty Ltd (‘Farah’), I asked Professor Lee what he thought about it. He said this: ‘Well, David, after all these years of reading cases I think that cases where plaintiffs don’t win generally don’t decide very much about the law.’ Then he said: ‘But I don’t know, what do you think?’ I was taken aback. At that time, I was full of the joys of the High Court’s decision. First, I thought it had rescued indefeasibility from the scrap heap, particularly so far as bank mortgages were concerned. Secondly, whilst I now agree with Professor Keith Mason’s point of view that the High Court’s treatment of the New South Wales Court of Appeal was intemperate, I was not unhappy then that the High Court had stemmed the tide of those who were intent on bending first limb Barnes v Addy liability into a restitutionary framework.</em>

A series of infrared images from the Japanese geostationary meteorological satellite (GMS) for the period late July to early December 1980 was found to reveal many useful oceanographic features of the western Tasman Sea. Although the temperature signal is digitized in steps of 1.73� C, the disadvantage of this somewhat coarse thermal resolution was offset to some extent by the availability of frequent images. The positions of eddy centres could be estimated within �0.25 of an eddy diameter from September onwards, and it was possible to follow their movements over time scales of the order of a month. The hot surface 'core' of the East Australian Current off northern New South Wales was discernible intermittently on images, and composites of core positions over a month revealed complex time variations in current axes. Cloud cover is a major limitation for infrared imagery, but some oceanographic feature was discernible on 63% of images.

The Face

Comparison of the salinity within and around warm-core eddies of the western Tasman Sea has shown (a) that such eddies have their origin solely within waters of the East Australian Current (EAC); (b) that as these eddies drift southward within the EAC, their salinity characteristics differ little from those of the surrounding water; (c) that after separation from the EAC at around 34�S., their salinity characteristics are generally conserved in the face of much lower salinities of the surrounding waters. This latter feature was especially marked in the case of eddy J, which maintained in the upper 250 m an abnormally high salinity signature to as far south as 40� Below 300 m, this eddy J contained remnants of another high-salinity eddy. Possible derivations of these deeper waters are examined.
