In situ measurements of snow accumulation in the Amundsen Sea Embayment during 2016

This dataset contains measurements of snow accumulation over an 11-month period in 2016 at six sites in the Pine Island-Thwaites Glacier catchment of West Antarctica. The sites were visited on two occasions, the first in January 2016 and the second in December 2016. The accumulation rate at each site was calculated using an average density profile, based on a compilation of six low elevation sites on Pine Island Glacier (iSTAR sites 15-19, and 22; Morris et al., 2017) that are situated nearby. The average density for the top metre based on this compilation is 419 kg m-3. Further details are provided in the associated publication.

Explanation: See the referenced specification

Pass: No

Statement: The measurement uncertainty is no more than 10 cm. The time period over which the measurements were collected is short, thus uncertainties related to internal ice deformation, glacier flow and drift are likely to be minimal.
