Dr Mark Curran from the Australian Antarctic Division and ACE CRC talks about his role as an Ice Core scientist and the relationship between the ice core record and our climate.

Dr Rhian Salmon, IPY Education and Outreach Coordinator, gives an overview of the International Polar Year 2007 - 2008.

December 4th, 2008, was our seventh International Polar Day (including the launch), this time focusing on research 'Above The Polar Regions'. You'd think by now we would know how to do these... but every time, without exception, is experimental and exciting. Much like the IPY science we are discussing. In the following days, we heard from people around the world: Brazil The last IPY Day, ...

Today, Thursday December 4th, IPY is celebrating it's seventh International Polar Day, this time focussing on research Above The Polar Regions. In conjunction with this event, several IPY partners have released new information about their projects. Here are some examples: *** Global Interagency IPY Polar Year Snapshot GIIPSY ...

New rifts have developed on the Wilkins Ice Shelf that could lead to the opening of the ice bridge that has been preventing the ice shelf from disintegrating and breaking away from the Antarctic Peninsula. Full Story, including animations The ice bridge connects the Wilkins Ice Shelf to two islands, Charcot and Latady. As seen in the Envisat image above acquired on 26 November 2008, new rifts (denoted by colourful lines and dates of the events) have formed to the east of Latady Island and appear to be moving in a northerly direction. Dr Angelika Humbert from the Institute of Geophysics, Münster University, and Dr Matthias Braun from the Center for...

Solar Linkages to Atmospheric Processes (SLAP) is an International Polar Year project investigating the links between changes in solar output and weather and climate. Thunderstorms and lightning strikes drive electricity around the world and form part of a global 'atmospheric electric circuit' that flows between the ground and the lower reaches of the ionosphere – about 80km up. Thunderstorms and electrified clouds are the 'batteries' of the atmospheric electric circuit, which drive the current from the ground to the ionosphere, while lightning is a visual representation of the current. The flow of current around the world is modulated by cosmic rays, whic...

As part of the field season of the 2007 International Polar Year, the Zackenberg research station was kept open two months longer than normal to host the project: Influence of Snow and Ice on the Winter Functioning and Annual Carbon Balance of a High-Arctic Ecosystem (ISICaB). This opening gave us a chance to observe autumn and early-winter carbon fluxes. Six automated chambers provided methane flux measurements once per hour, day and night in a typical fen area. At the end of the growing season, emissions decreased during September until they reached the presumed low winter emission level. However, at the onset of soil freeze-in, a substantial increase in emissions was observed and was sustained for several weeks, corresponding to the time required for a complete freeze-in of the entire a...
