Julian connects with earth scientists and educators in New Zealand and overseas
A visit to Fox Glacier shows that changes over the last 5 years are similar to those at the Franz Josef Glacier. Here is a view of the Fox Glacier front in 2009: And this year (March 2014): The terminal face from another angle in 2009… …and as it was recently in 2014. The grass […]

This week I have been with Cornel de Ronde and a group of ocean floor researchers applying more of their methods to expand the large amount of research of Lake Rotomahana done over recent years. This is the lake that used to be decorated by the famous Pink and White Terraces. It was excavated by

Some images I took this morning, on an early walk through Christchurch City Centre. I offer my best wishes to the folk of Christchurch and other Canterbury towns who are still patiently rebuilding their livelihoods, three years on from the 22nd February 2011 aftershock. We Remember:

Simon Cox GNS Science M. McSaveney GNS Science Slip Stream is a tributary to the Dart River in the South Island of New Zealand. There has been an active landslide here for several thousand years, periodically sending down lobes of debris to gradually build up a large fan in the Dart Valley. There was

The Tasman Glacier is the largest glacier in New Zealand. Its upper section is mostly white as you would expect of a river of ice. However, the lower half is covered with a layer of rock debris about a metre thick. This forms an insulating layer that slows down surface melting and allows the glacier

Mount Cook rock avalanche 1991. Lloyd Homer, GNS Science On 14th December 1991 a massive rock avalanche occurred from the East Face of Aoraki /Mount Cook, sending an estimated 14 million cubic metres of rock in a 1.5 kilometre wide cascade across the grand plateau and down onto the Tasman Glacier. It is thought that

K-Pg boundary layer – when the Earth changed forever The K-Pg Boundary (or Cretaceous Paleogene boundary, or K-T boundary as it is still sometimes called) is a layer in the Earth’s crust that marks a very dramatic moment in the history of life on earth about 65 million years ago. There is a huge change

To quantify the linkage between weather events and sedimentation in Lake Ohau, a weather station has been set up in the valley at the head of the lake. This is only possible due to kind assistance from the Inkersell family at Lake Ohau Station. I accompanied Heidi Roop to the weather station as it needed a

Ever since its creation by the retreat of a huge glacier at the end of the last ice age, Lake Ohau has been gradually filling up with sediments washed down from the nearby mountain ranges. This is the view looking north from the lake, up towards the Dobson Valley. The valley profile has the classic
