ARTICLES Waterlogged and Weary, but Wowed! By Stephen Keable and the team members AMRI's Marine Invertebrates and Malacology staff have recently returned from the six-week long Southwest Pacific Expedition with an amazing number of samples that will be used to evaluate the marine biodiversity of some seldom visited locales. and lagoons to deep, steeply sloping reef fronts. Diving was supplemented with intertidal collecting, baited traps, and use of a light at night to attract fishes and invertebrates which were captured with a net. Stephen Keable writes the next chapter of this expedition, the experiences had by the team and the importance of the data for museum research into the future. At times the diversity of both the fishes and invertebrates was overwhelming leading to some very late nights to sort, catalogue and preserve the specimens. Expedition Team: Dr Stephen Keable, Dr Elena Kupriyanova, Anna Murray, Mark McGrouther, Sally Reader and Dr Mandy Reid. After an intrepid six weeks at sea the South West Pacific Expedition concluded in early September. For this voyage AMRI scientists, Mark McGrouther and Sally Reader (Fish Collection); Steve Keable, Elena Kupriyanova and Anna Murray (Marine Invertebrates Collection); and Mandy Reid (Malacology Collection), joined international colleagues in undertaking biological surveys and genetic sampling aiming to compare the biodiversity, population connectivity and community structure of marine environments in the outer reefs and islands of New Caledonia, Fiji and Tonga.

The Australian Museum invertebrate team members focused particularly on crustaceans (such as crabs and shrimp), marine worms and molluscs (including snails, bivalves, octopuses, nudibranchs) for research projects currently underway and as a reference for future study. Steve noted a highpoint for him wasn’t necessarily the diving (spectacular though it was) but some of the intertidal collecting. He commented, “We were privileged to be able to visit the intertidal flats at Ogea Levu, in the southern Lau Island Group, Fiji. Apart from being visually spectacular, with lots of little islands that were eroded in the intertidal area so they appeared to be growing on stalks like mushrooms, the biodiversity was amazing. I’m used to temperate areas, here I was seeing more species than I could count. I’m optimistic that the data we collected will help feed into conservation efforts underway in the region”.

Among the crustaceans, highlights included several mantis shrimp (Stomatopoda) that were collected using a suction pump from burrows on sediment flats at low-tide. The remote location and unusual sampling method suggest these will provide valuable new information for studies examining the distribution and relationships of these animals. Beach hoppers (Amphipoda: Along the way there was plenty of opportunity for hand-collecting while scuba diving, the main sampling technique of the voyage, with two dives a day being the usual routine. In total the group logged 90 dives in habitats ranging from shallow reef flats 25 SCIENCE EDUCATIONAL NEWS VOL 66 NO 4
