4. Longer-Term Mass Balance Objective

During the 1999/2000 season mass balance measurement devices (submerge velocity method (Hamilton et al., 1998; Hamilton & Whillans, 2000)) have been deployed at Victoria Lower Glacier and at Evans Piedmont Glacier during 2004/05. The measurements at Victoria Lower Glacier show that the glacier has a slightly negative mass balance, losing around 12cm thickness per year. A continuation of the measurements will allow monitoring changes in the ablation intensity of the McMurdo Sound Region.
