Dr Mike Williams (NIWA)


Mike’s research interests are in New Zealand's Deep South region, and are centred on ice-ocean interaction both in sea ice, and under Antarctica’s ice shelves. He is also interested in the changing climate in the Southern Ocean and New Zealand’s Subantarctic. Prior to starting at NIWA in 2001, Mike completed a PhD in oceanography at the University of Tasmania, and was an Assistant Research Professor at the University of Copenhagen, where he worked on coastal ocean circulation off Chile and tracking icebergs across the North Atlantic.

Anne-Marie Rowe (NIWA)

Challenge Manager

Anne-Marie comes to us from our sister National Science Challenge, Resilience to Nature's Hazards, and brings crucial experience navigating the relatively new, many-headed creatures that are the NSCs. Anne-Marie also has around 20 years of experience in university research management, more recently at Victoria University of Wellington, with previous research management roles at Massey University and University of Otago’s Christchurch School of Medicine and Health Sciences.

Dr Olaf Morgenstern (NIWA)

Earth System Modeling and Prediction

Olaf holds a PhD in meteorology and has worked in the UK and Germany on the development of atmospheric chemistry and chemistry-climate models. He has led chemistry-climate modelling at NIWA since 2009 and has been a Programme Leader since 2012. In addition, Olaf is a Principal Investigator of the core Capability and Clouds & Aerosols projects and the contestable Stratospheric Ozone project. The aim of the Capability project is to make available, support, and coordinate the development of the New Zealand Earth System Model (NZESM). The Clouds & Aerosols project is targeting the representation of Southern-Ocean clouds and aerosols, and the Stratospheric Chemistry project will improve the representation of stratospheric chemistry, particularly of the ozone layer, in the NZESM.

Sandy Morrison

Associate Professor Sandy Morrison (Waikato University) | Ngāti Whakaue, Ngāti Maniapoto, Ngāti Rārua ki te Tau Ihu, Ngāti Tama ki te Waipounamu

Vision Mātauranga

Sandy is tribally grounded, globally informed and whānau tested against the everyday realities in which whānau exist. From 2004-08, Sandy served as President of the Asia South Pacific Association for Adult and Basic Education (ASPBAE), the largest non-government organisation on adult education in the world. Sandy was also inducted into the International Adult and Continuing Education Hall of Fame by the University of Oklahoma. Her current position as the Assistant Dean (Academic) for the University of Waikato’s Faculty of Māori and Indigenous Studies allows her to continue to challenge the thinkers of tomorrow and concentrate on her research interests around Treaties, Adult Education and Indigenous Development. Sandy leads the Te Tai Uka a Pia (Iwi relationships with the Southern and Antarctic Oceans) project in the Vision Mātauranga programme, and is also part of the Culture and Climate Change project of the Engagement programme.

Anita Wreford (Lincoln University)

Impacts & Implications

Anita Wreford is an expert in the economics of climate adaptation, particularly in the natural environment, agriculture and forestry sectors. She’s been involved in many fields of climate research, from infrastructure to agriculture to trade. Anita has worked around the world, with the IPCC, the EU Commission, the OECD, the UK’s Committee on Climate Change and the Scottish Government’s ClimateXChange programme. 

Mike Harvey

Dr Mike Harvey

Processes and Observations

Mike has a PhD in environmental physics and has led atmospheric research programmes at NIWA for the last 14 years. He’s had a long-term interest in improving our understanding of important environmental processes, which among other things helps us understand the efficacy of some climate change mitigation actions. Mike has been involved in the Phase 1 Clouds & Aerosols project, making targeted observations to improve the representation of Southern-Ocean clouds and aerosols in the NZESM.

Living with Uncertainty: Call for research ideas

In recent years, the policy landscape for climate adaptation in Aotearoa has shifted dramatically. There is also growing recognition that stakeholders and end users require methods and tools that help them make decisions despite uncertainty about the future.

Our Kāhui Māori to protect and guide Antarctic as well as climate adaptation research

The Deep South Challenge: Changing with our Climate is humbled and excited that its Kāhui Māori have agreed to share their knowledge with the Antarctic Science Platform, and to act as its Kāhui Māori (Māori advisory group) as well.
