Assertion: glacier's mass balance | /r/CapableOf | reduce uncertainty
Facets:
value: in calculated balance thickness
type: OTHER
Source sentences:
text: On a fast changing glacier like Jakobshavn Isbræ, the rates of thickness change are large (15–30 m/yr), the apparent mass balance is not negligible and measurements of ∂H /∂t are needed to reduce uncertainties in calculated balance thickness.
