Welcome to The Wanaka Branch of the
Royal Society of New Zealand.

The Wanaka group was formed in February 2013, becoming the 9th Regional branch of the Royal Society of New Zealand which is based in Wellington. Consistent with the aims of the central organisation, the main objective of the Wanaka Branch is to advance and promote science, technology and humanities in Wanaka and the Wanaka region.

The Branch seeks to achieve this by offering a series of 6 to 10 lectures each year. It aims to bring speakers who are highly regarded in their field of knowledge and expertise, as well as good communicators. Each year a number of eminent national and international speakers, who tour New Zealand under the umbrella of the Royal Society Wellington are included in the programme.

The Wanaka Branch is constituted as an unincorporated society and comprises a membership who appoint an executive committee at an AGM held in May each year. Members receive advance notices of lectures and other communications by email. Lectures are open to the public, and usually held at 6pm on a Friday in the Presbyterian Community Centre, 91 Tenby St, Wanaka.

Alpine fault earthquake: Ground shaking and impacts

Tuesday 10 December at 6.00pm, at the Presbyterian Community Centre, 91 Tenby Street, Wanaka.
Professor Brendon Bradley, College of Engineering, University of Canterbury/Director of QuakeCoRE.
Cost – FREE – Everyone Welcome.

What could an Alpine Fault earthquake feel like and how is world leading research in earthquake resilience helping us prepare?

“We can’t predict when an earthquake will hit but we can predict how strong the ground shaking will be at certain geographic locations,” Professor Brendon Bradley says. His award-winning research is being used to set new international building design codes, and several major rebuilding projects in Christchurch are being influenced by his findings.

Brendon is a Professor of Earthquake Engineering and Director of QuakeCoRE; the New Zealand Centre for Earthquake Resilience – a network of over 180 active researchers. The research uses sophisticated seismic hazard analysis and assessment modelling, and pioneering ground motion simulation to identify and mitigate earthquake impacts.

Brendon’s modelling relies on physics-based data, examining the geological and geophysical properties of rock and soil at specific locations. This differs from traditional ground motion modelling, based primarily on observation and generalised information.

Since 2012, and with the help of two government-funded super computers in Auckland and Wellington, QuakeCoRE has been working on a system to model the “process” of an earthquake. This help quake experts make more informed predictions about how the ground will move in a certain spot.

“Our idea is basically to get to a point where we provide the same sort of information as a weather forecaster would tell you … Just as when you have a severe weather warning, we would provide you the same information about severe ground shaking and the consequence to buildings,” says Brendon.

Our Lakes’ Health: Past, Present and Future

Friday 7 February at 6.00pm, at the Presbyterian Community Centre, 91 Tenby Street, Wanaka.
Drs Marcus Vandergoes (GNS Science) & Susie Wood (Cawthron Institute) and the Lakes380 team.
Cost – $5 per person.

The health of our lakes is central to New Zealand’s environmental, economic and cultural wellbeing. Yet we cannot robustly assess the water quality or ecological health of our 3,800 (> 1 ha) lakes because over 95% of them are not monitored. Even for the few lakes that are monitored, datasets are short (<20 years), and assessment incomplete, because monitoring started after those lakes had deteriorated. Lake sediments are natural archives that continuously record environmental history, providing measures of current and historical aquatic communities and water quality – equivalent to many centuries of environmental monitoring. The ‘Our lakes’ health; past, present, future (also known as Lakes380)’ is a fiveyear research project which aims to collect water, surface sediment and sediment core samples from 10% of New Zealand lakes. A suite of novel and traditional methods are been used to explore shifts in lake health over the last 1,000 years (pre-human arrival in New Zealand). In this talk we use examples from a subset of lakes which we have already analysed to demonstrate how molecular techniques can be combined with hyperspectral scanning and traditional methods including pollen and pigments to reconstruct biological communities and identify the timing of changes in lake health. The project team has also undertaken a series of Interviews with policy experts, lake scientists and others involved in key actions that influence lake management in New Zealand. These sit alongside a review of the legislation that affects lake management and protection, from 1840 through to today. Two case studies are underway where the Lakes380 team is working closely with the Rangitīkei iwi and iwi in the Wairarapa Moana to explore how we can create an enriched understanding between mātauranga Māori and scientific reconstructions to enhance knowledge on lake health/mauri. We will provide an overview of these pieces of work. For more information, visit: https://www.lakes380.com and https://www.instagram.com/lakes380/

Profiles
Co-programme leaders’: Drs Marcus Vandergoes (GNS Science) & Susie Wood (Cawthron Institute)
Marcus is a paleoecologist whose research focuses on reconstructing historic environmental change through the analysis of lake sediment cores. He works on a variety of projects including exploring how ecosystems and environments have responded to climate change, landscape evolution and human impact. Susie is a freshwater scientist and molecular ecologist. She works on multiple projects related to New Zealand’s aquatic systems, with a focus on lake health, cyanobacterial blooms in lakes and rivers and the application of DNA-based tools for characterising and understanding aquatic ecosystems.

The Lakes380 team
The Lakes380 team includes over 50 researchers and students from eight different New Zealand organisations and international collaborators from Australia, USA, Canada, UK and Europe. Their expertise spans paleo-limnology, lake dynamics, social science, Māori environmental and resource management, molecular techniques, geochronology and climate and environmental change.

Title TBC (Stratospheric processes and their role in climate)

Friday 6 March at 6.00pm, at the Presbyterian Community Centre, 91 Tenby Street, Wanaka.
Professor Greg Bodeker, Adjunct Professor at the Climate Change Research Institute.
Cost – $5 per person.

Greg has been Adjunct Professor at the Climate Change Research Institute since October 2009. Greg is Director of Bodeker Scientific, a private research company currently employing 4 people, and specialising in stratospheric processes and their role in climate. Greg had previously worked for NIWA from May 1994 to August 2009. He is currently co-chair of SPARC (Stratospheric Processes And their Role in Climate) one of four core projects of the World Climate Research Programme. He is also co-chair of GRUAN (the GCOS Reference Upper Air Network) a state-of-the-art network initiated as a core part of the Global Climate Observing System (GCOS) for monitoring long-term changes in the climate of the whole atmosphere. Greg has also contributed as a coordinating lead author to WMO/UNEP ozone assessments.
