In 2016-2017 we conducted a field study at LeConte Glacier, Alaska, to study the impacts of subglacial discharge on plume dynamics and submarine melting. As part of that study, eight time-lapse cameras documented the terminus and proglacial fjord of LeConte Glacier, Alaska in order to (i) track iceberg motion, (ii) document changes in glacier terminus position and calving activity, and (iii) estimate seasonal variations in glacier velocities. The camera frame rates varied. Four cameras (UAS1-UAS3, UAS5) took photos of the fjord every one to two minutes for ~10 hrs per day, depending on the season. Three cameras took photos of the glacier every hour (UAS4 and Hunting1-Hunting2). An eighth camera (UAS6) took photos every 15 s during three short field campaigns in 2017; the frame interval of cameras UAS1-UAS3 and UAS5 was also reduced to 15 s during the final field campaign.
