TERME PRÉFÉRENTIEL

ICE SHEET MEASUREMENTS  

DÉFINITION

  • Scientists have adopted three general approaches to ice sheet mass balance measurement: comparing outflow and melt to snowfall accumulation (the mass budget method), observing changes in glacier elevation (volume change or geodetic method), and detecting changes in the Earth’s gravity field over the ice sheet (gravimetric method).
