Moriori – assuredly a story worth telling.
Presbyterian Community Centre, 91 Tenby Street, Wanaka, NZ

Speaker: Dr Doug Sutton, University of Auckland (Retired).

This paper summarises research over the last fifty years which has clarified what we now know about:

The  original discovery of the Chatham Islands,
The indigenous development there of Moriori population, culture and society,
The nature of Moriori society as it was prior to new arrivals,
The demographic, environmental, social and cultural impacts of rediscovery by sealers and whalers, and the enduring occupation of the islands by new settlers.
The condition of Moriori by 1870.

It reviews the Moriori struggle for survival which was set in motion by the herculean efforts and tactical genius of Hirawanu Tapu (1824-1900) and codified, a hundred years after his death, by settlement with the Crown.

Spectroscopy in 21st century New Zealand: from solar cells to fish waste
Presbyterian Community Centre, 91 Tenby Street, Wanaka, NZ

Speaker: Professor Keith Gordon, Department of Chemistry, University of Otago.

Vibrational spectroscopy is a potent method of analysing molecular structure within small volumes and at fast timescales.  In this presentation I will try to cover off three related but distinct areas of interest.

Firstly, I will discuss how using a suite of spectroscopic methods, and by studying a series of complexes (metal-based donor-acceptor systems) in which parameters are carefully controlled,1 it is possible to develop design principles for excited state properties such that one can enhance electronic absorption and increase excited state lifetimes.2  Useful properties in both solar cells3 and photocatalysis.  The understanding of how these properties, both ground and excited state, are modulated by driving force and effective conjugation is not straightforward.

Secondly, the use of computational chemistry in modelling properties of compounds has become ubiquitous in modern chemistry.  However these do not always predict molecular behaviour effectively and unpicking the extent of deviation between theory and experiment reveals some interesting problems in our reliance on computational methods.4 Our studies on the spectroscopy of donor-acceptor and π, π* systems highlight these issues.5

Finally, our experimental development, originally aimed at understanding ground and excited state properties of metal complexes and other donor-acceptor systems, has provided us with tools that are amenable to analytical spectroscopy.  These are critical techniques that can add value to products in New Zealand. I will outline some of these  in the study of primary produce and pharmaceuticals.  More recently we have used low-frequency Raman spectroscopy6 to evaluate crystallinity (and order in general) in structures as varied as solar cell polymers7 to active pharmaceutical ingredients.8 Our studies in these areas will also be described.

UP THE CREEK – UNRAVELLING THE SECRETS OF NEW ZEALAND’S STREAMS
Presbyterian Community Centre, 91 Tenby Street, Wanaka, NZ

Speaker: Emeritus Professor Colin Townsend, University of Otago

You may not be surprised to learn that if New Zealand’s rivers were to be placed end to end they would total 9,471 km in length. But did you know that the streams that feed those rivers total more than 400,000 km! Did you know that the beds of such streams that have been reached by the introduced brown trout tend to be more slippery than those still occupied by native fish? Or that an ancient whitebait species became ‘landlocked’ into headwater streams of the South Island and evolved into 12 or more new non-migratory species? Or that streams whose beds are disturbed at an intermediate rate have a higher biodiversity than streams turned over by more frequent spates or not disturbed at all? Or which of the human-caused impairments (nitrogen, sediment, water abstraction, increased temperature) is most harmful to stream ecosystems? Well nor did I - until my research team started work three decades ago.

CHOOSING THE FUTURE OF ANTARCTICA

Friday 18 October at 6.00pm, at the Presbyterian Community Centre, 91 Tenby Street, Wanaka. Professor Tim Naish, Antarctic Research Centre, Victoria University of Wellington. New Zealand Antarctic Society National Speaker for 2019 Cost – $5 per person. I will present two narratives on the future of Antarctica and the Southern Ocean looking forward 50 and 300 years. In the first, greenhouse gas emissions remain unchecked, the climate continues to warm, and the policy response is ineffective; this has large ramifications in Antarctica and the Southern Ocean, with worldwide impacts. In the second, ambitious action is taken to limit greenhouse gas

Genetic Tools for Pest Eradication – Looking Back to Go Forward

Friday 11 October at 6.00pm, at the Presbyterian Community Centre, 91 Tenby Street, Wanaka. Professor Neil J. Gemmell, Department of Anatomy, University of Otago, PO Box 56, Dunedin 9054, New Zealand. Cost – $5 per person. New Zealand has set an ambitious goal to eradicate mammalian predators from our shores by 2050. The key targets are possums, rats and stoats; species that cause enormous damage to our flora and fauna and in some cases are an economic burden to our productive sectors. As all of these species were introduced to New Zealand from elsewhere there is little sympathy nationally for

Seeing more using x-ray colour

Friday 16 August at 6.00pm, at the Presbyterian Community Centre, 91 Tenby Street, Wanaka. Dr Hannah Prebble, Clinical Application Researcher at MARS Bioimaging Ltd.

Avoiding conservation by numbers: how genetics can help save threatened species

Friday 2 November at 6pm, at the Presbyterian Community centre, 91 Tenby Street, Wanaka. Dr Helen Taylor, Department of Anatomy, University of Otago. Research fellow Dr Taylor’s science communication about conservation genetics and threatened species resulted in her last night being awarded the 2018 Callaghan Medal for an outstanding contribution to science communication and raising public awareness of science. Conservation is often a numbers game – if we increase the size of a threatened species’ population, we consider this a conservation success. Unfortunately, population growth is not always the full story; factors such as genetics have a big part to

Flexible energy services are key to the transition to a low-carbon, highly-renewable energy system for NZ

Friday 17 August 2018, 6.00pm, Presbyterian Church Hall, 91 Tenby St, Wanaka. Dr Michael Jack, Director of Energy Management Programme, Physics Department, University of Otago. Variable generation from renewable sources (e.g. wind and solar) and acute peaks in electricity demand are increasingly challenging for electricity systems, especially when combined with ageing and constrained local networks. These issues are likely to intensify due to increasing uptake of grid-connected technologies (e.g. photovoltaics, electric vehicles) and future electrification of transport and heating. NZ is already facing these difficulties due to its current ~80% renewable generation, accelerating uptake of novel technologies and the government’s
