| Summary: | <p>CryoSat can provide temporal height change around the
Greenland Ice Sheet including that close to the terminus of many glaciers.
Height change from the northern outlet of the Humboldt Glacier in
northwestern Greenland is combined with ice flux into and out of sections
of the glacier basin to derive the water run-off each year from 2011 to
2019. The cumulative 9-year run-off for this part of the Humboldt basin
is <span class="inline-formula">9.6±2.9</span> km<span class="inline-formula"><sup>3</sup></span> and is predominantly sub-glacial at the
terminus, with large run-offs occurring in 2012, 2015, and 2019 and much
smaller ones in 2013, 2016, 2017, and 2018.</p> |
