.................................................................................................................................................................................................. 19 Dr. Andrew Fountain, a McMurdo LTER participant, returned to the Taylor Valley with his field team to continue research on the Commonwealth, Canada and Taylor glaciers, as well as to study features in the Garwood valley. Studies focused on surface snow and ice accumulation and ablation, while monitoring solar and other environmental influences on the overall dynamics of the glaciers. This season the B-504 team once again requested use of the ground based terrestrial LiDAR to scan portions of the Commonwealth Glacier and their study site in the Garwood Valley. A UNAVCO engineer performed the laser scans and provided data post processing. GPS PPK gear was supplied for the season as well. ........................................................................................................................................................................... 19 B-505 (Doran) ....................................................................................................................................................................................................... 19 B-518 (Kennicutt) ................................................................................................................................................................................................. 19 C-514/515 LARISSA (Domack) .............................................................................................................................................................................. 19 C-520 (Anandakrishnan) ....................................................................................................................................................................................... 19 G-049 (Rack) ......................................................................................................................................................................................................... 20 G-058 (Harvey) ..................................................................................................................................................................................................... 20 G-079 (Wilson) ..................................................................................................................................................................................................... 20 G-081 (Kyle) .......................................................................................................................................................................................................... 20 G-098 (Blankenship) ............................................................................................................................................................................................. 21 G-501 (Putkonen) ................................................................................................................................................................................................. 21 I-156 (Balco) ......................................................................................................................................................................................................... 21 I-158 (Rupper) ...................................................................................................................................................................................................... 21 I-181 (Winberry) ................................................................................................................................................................................................... 22 I-196 (Hall) ...........................................................................................................................................................................................................
