Extreme Experiments: A comprehensive plan to validate Cryosat in the Arctic and Antarctic

Extreme Experiments: A comprehensive plan to validate Cryosat in the Arctic and Antarctic

Note: This page is an archived page dating from the year 2004. Read about CryoSat-2.

Prof Elizabeth Morris of SPRI and John Pailthorpe are working as part of a team of scientists to validate data from the European Space Agency Cryosat project.

CryoSat is a radar altimetry mission that aims to collect information about variations in thickness of polar ice sheets and sea ice to support research into climate change.

The CryoSat website provides some of the most up to date information available about research into climate change.

News updates from Prof. Liz Morris and John Pailthorpe in Greenland

17th September 2004

We are still at camp P21, work progressing toward the last few days.

Hopefully the UK1 and UK2 teams will be uplifted on Monday or Tuesday.

The radar overflight has been successful and Liz continues to measure density over the 1 km2 test site.

The weather has been clear but very cold recently, rarely above -30 °C even during the day.

Northern Lights putting on a good show.

Everyone looks forward to hot showers and fresh food next week!

7th September 2004

We are at T21 and will be here for a few more days. Co-ordinates: N70° 33" W 43°02".

An aircraft carrying a radar altimeter, similar to the CRYOSAT one, will be flying over the site in the next few days.

Weather changeable. Storm passing over last Tuesday (7th) forced us to stop travelling and pitch camp. Temperatures at the moment are about -25°C, but a constant wind makes it feel much cooler outside.

Work still going well, good data coming in.

We had a birthday party for Liz Morris during the storm with candles, presents and a toast!

1st September 2004

We're at camp P35, N 70° 51' W 39° 33'. We've hit a bad weather patch after a good start. Big storm last night, but past now. Weather is quite warm -5° C to - 10° C. Liz overcame a minor technical hitch and is continuing to get good data. We are still ahead of schedule and hope to move on tomorrow but will need weather to improve. Our colleagues from Scotland (UK2 team) are now established at camp P5 on the West of the icecap. With good travelling and data under our belt we are happy with progress so far.

26nd August 2004

Today we are moving to camp P41B. The position is 71° 15' North and 37°51' West. Three good days work for Liz. Neutron probe is showing good repeatability with some change in density near surface. Temperature fluctuating between -15°and -30°C. The sun is dipping below the horizon at night making nights quite chilly. Travelling surfaces are very good and it takes about 2 hours to do 40 km between camps. UK2 team are in Kangerlusuaq and will be going to camp T5 soon. Spirits high. All going well so far.
