Researchers from Norway and China have collaborated on developing an autonomous buoy with instruments that can more precisely measure the optical properties of Arctic sea ice while also taking measurements of ice thickness and temperature.
Together with his AWI colleague Dr Stefan Hendricks, they evaluated the sea ice thickness measurements taken over the past five winters by the CyroSat - 2 satellite for their sea ice projection.
«He has pioneered the use of AUVs (autonomous underwater vehicles) to measure under - ice topography and has worked with the Royal Navy since the 1970s in carrying out ice thickness measurement work from Navy submarines on Arctic deployments.»
results (of direct ice thickness measurements by bore holes coupled with historic data) in October 2009, Professor Wadhams said,....
All of these measurements are useful, but the trouble is that even with many thousands of them logged, the proportion of the ice pack measured is much smaller than the complete thickness profile of the entire ice cap you'd like to have, if only you could.
To determine how much ice and snowfall enters a specific ice shelf and how much makes it to an iceberg, where it may split off, the research team used a regional climate model for snow accumulation and combined the results with ice velocity data from satellites, ice shelf thickness measurements from NASA's Operation IceBridge — a continuing aerial survey of Earth's poles — and a new map of Antarctica's bedrock.
By comparing measurements of ice thickness between 1958 and 1976 with data from 1993 and 1997, he determined that the thickness had decreased from 10.2 feet in the early period to 5.9 feet in the 1990's.
By comparing changes in ice thickness taken in 1999 to measurements made earlier in the decade, they concluded that the continent is giving up nearly 50 gigatons — that s 50 billion tons — of water per year, with greatest losses coming from the eastern coast.
