2024 Field Work Victoria Fjord, Northern Greenland

2024 GreenDrill — Glacial geologists Jacob Anderson, Allie Balter-Kennedy and Nicolás Young of Lamont-Doherty Earth Observatory, and Brandon Graham of USGS were in northern Greenland investigating rates of ice sheet retreat since the last glacial period by collecting bedrock cores to determine how sensitive the northern section of the Greenland ice sheet is to changing climate.

Slide 1: What looks like 'mountain toes’ border the Greenland coast with ice flowing between the rock sections.
Slide 2: The sun hangs low in the sky highlighting the rough surface
Slide 3: Setting up the seismics for ice testing
Slide 4: Tents are set up with flags marking their location in case of storm.
Slide 5: The change in ice surface is reflective of how fast and over what it moves. The flat surface shows floating ice, the wrinkles and ridges show ice that is accelerating compared to the ice around it.
Slide 6: A spectacular polar sun dog that appeared on a bright sunny days.
Slide 7: Greenland buildings are often painted bright colors - yellows, reds, greens, purples.
Slide 8: The days are short in the spring when the field work was underway.
Slide 9: Handrills are used to help set the small explosives in the ice.
Slide 10: A small, concentrated explosive (PETN) is lowered into the ice, that when triggered, sends sound vibrations down into the ice.
Slide 11: Wind and storms that move through the area mound snow and ice over the equipment.
Slide 12: Ice is shot into the air as the small explosion is set off.
Slide 13: Camp site one from above. Yellow tents appear small on the icesheet but the yellow color helps them stand out.
Slide 14: Snowmobiles are the way to move quickly across the ice surface with sledges towed behind.
Slide 15: Setting out on snowmobiles to check the area.
Slide 16: Jen after travelling by snowmobile. Covering up is important as ice collects on clothes and any exposed surface.
Slide 17: The colors of the sun, sky and ice as the sun hangs low in the sky.
