    Summary

    The extensive territorial waters of Australia and New Zealands (NZ) (over 8 million km2 for Australia and a further 4 million km2 for NZ) are home to approximately 49 species of whales and dolphins, 11 species of seals and the dugong. Within Australia, at least eight species are listed as threatened, though there is insufficient information on a further 25 to determine their conservation status, while in NZ eight species are listed as threatened. The relationship between humans and Australasia’s marine mammals is culturally diverse and has changed significantly in recent years. Dugongs and stranded whales have been important both spiritually and as a source of nutrition to some Aborigines and Torres Strait Islanders for thousands of years; seals and whales had a similar role for Maori in NZ. In recent history, exploitation of baleen whales, elephant seals and fur seals was an important driver for much of the earliest European settlement of Australasia. The success of the whaling and sealing industries came at the expense of marine mammal populations, leading to the near extirpation of many species by the mid twentieth century. In more recent decades there has been a fundamental shift in public attitudes towards marine mammals, in particular the great whales and dolphins. All marine mammals are protected within Australia and NZ waters. Traditional hunting of dugongs is legal in Australia for Native Title holders.

  • The use of photons to create intricate three-dimensional and buried structures [1] in photo-structurable glass has been well demonstrated at several institutions [2]. In these instances the glass used whether it be Foturan™, made by the Schott Group or a similar product made by Corning Glass, forms a silver nucleation sites on exposure to intense UV laser light via a two-photon process. Subsequent annealing causes a localized crystal growth to form a meta-silicate phase which can be etched in dilute hydrofluoric acid at rates of 20 to 50 times that of the unprocessed glass. The same formulation of glass can be “exposed” using a particle beam to create the nucleation site. In the case of particle beam exposure, experiments have shown that the mechanisms that cause this initial nucleation and eventual stochiometric transformation, after annealing, depend largely on the beam energy.
