Prickett Auckland War Memorial Museum Abstract An obsidian flake collected from Macauley Island during the Kermadec Expedition has been analysed to determine the source. The result indicates a Mayor Island, New Zealand, origin, supporting previous results on obsidian from Raoul Island that Polynesians travelled back into the Pacific from New Zealand.

Due to its inaccessible location, the seafloor of the deep-sea trench can only be visualized using remote sensing tools and advanced algorithms of data analysis. The importance of the developing and technical improving of the innovative methods in cartographic data processing is indisputable. -

Conservation Status of New Zealand Marine Mammals, 2019 Report
2019 NEW ZEALAND THREAT CLASSIFICATION SERIES 29 Conservation status of New Zealand marine mammals, 2019 C.S. Baker, L. Boren, S. Childerhouse, R. Constantine, A. van Helden, D. Lundquist, W. Rayment and J.R. Rolfe Dedication This report is dedicated to the memory of Dr Rob Mattlin, a founding member of this Committee, who passed away in May 2019. Rob’s knowledge, insight and personality will be greatly missed by the Committee and by the marine mammals for which he was so passionate. Rob made New Zealand his home after leaving his native USA to undertake a PhD on New Zealand fur seals at Canterbury University. He proceeded to dedicate his life to marine science with a particular focus on marine mammals and spent most of his time based in New Zealand, apart from a role at the US Marine Mammal Commission. His contribution to our understanding of marine mammal biology and ecology and, in particular, his expertise in interactions with fisheries, was a key factor in achieving many positive outcomes for marine mammals in New Zealand. He made significant contributions to the conservation and management of both New Zealand sea lions and Hector’s dolphins. The Committee would like to recognise the unique balance of wisdom, humour, and tenacity that Rob brought to his work and hope that we can continue to match his enthusiasm and passion.

The Dammed Hikurangi Trough: a Channel-Fed Trench Blocked by Subducting Seamounts and Their Wake Avalanches (New Zealand-France Geodynz Project) Keith B
, Basin Research (1 998) 1O, 441 -468 The dammed Hikurangi Trough: a channel-fed trench blocked by subducting seamounts and their wake avalanches (New Zealand-France GeodyNZ Project) Keith B. Lewis,* Jean-Yves hollott and Serge E. Lallemand* NIWA, PO Box 74901, Wellington, New/ Zealand tORSTOM, Villefranchesur mer, France #Université de Montpellier /I, Montpellier, France ABSTRACT The Hikurangi Trough, off eastern New Zealand, is at the southern end of the Tonga- Kermadec-Hikurangi subduction system, which merges into a zone of intracontinental transform. The trough is mainly a turbidite-filled structural trench but includes an oblique- collision, foredeep basin. Its northern end has a sharp boundary with thedeep, sediment- starved, Kermadec Trench. Swath-mapping, sampling and seismic surveys show modern sediment input is mainly via Kaikoura Canyon, which intercepts littoral drift at the southern, intracontinental apex of the trough, with minor input from seep gullies. Glacial age input was via many canyons and about an order of magnitude greater. Beyond a narrow, gravelly, intracontinental foredeep, the southern trench-basin is characterized by a channel meandering around the seaward edge of mainly Plio-Pleistocene, overbank deposits that reach 5 km in thickness. The aggrading channel has sandy turbidites, but low-backscatter, and long-wavelength bedforms indicating thick flows. Levées on both sides are capped by tangentially aligned mudwaves on the outsides of bends, indicating centrifugal overflow from heads of dense, fast-moving, autosuspension flows. The higher, left-bank levée also has levée-parallel mudwaves, indicating Coriolis and/or boundary currents effects on dilute flows or tail plumes. In the northern trough, basin-fill is generally less than 2 km thick and includes widespread overbank turbidites, a massive, blocky, avalanche deposit and an extensive, buried, debris flow deposit. -
