Iceberg Allie) is a PhD student in the Climate Change Institute at the University of Maine. Doing good for the Earth is her main passion and priority. She's interested in ice-ocean interactions, like how melting land ice changes the physical properties of the ocean. She uses this information to improve Earth system models, which are valuable tools for climate predictions. On the rumple project she's in charge of the GPR and making sure everyone brings good vibes. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/985947e9-30e4-4941-a50e-41c677d10c44/20251220_025848u_20251220_031848u.diff.rec.annot.jpg Field Blog - Antarctic Field Work - 2025/26 - Make it stand out **Preliminary TRI Results** After some initial measurements, we settled on a 170-degree scan and an 8 km range. We acquired measurements every 2 minutes for one hour. The results, presented from an overhead view perspective, show excellent image quality of our target area with many critical features, including the undulating surface of the Rumple Zone and pressure ridges in the sea ice to the right of the rumples in the image. The colors represent 20 minutes of motion (~5-10 cm), likely due to flexure of the ice shelf due to ocean tides. The texture in the background image is the amplitude of the returned TRI signal, called backscatter. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/33350c4f-1d9d-41fb-975f-d8512885c937/DSC07495.jpeg Field Blog - Antarctic Field Work - 2025/26 - Dr. Ali Banwell - Field Team PI Ali (aka. Field Santa) is a glaciologist who holds dual appointments as a Research Scientist in the Cooperative Institute for Research in Environmental Sciences (CIRES), University of Colorado Boulder, and as a Professor in the Centre for Polar Observation and Modelling (CPOM) at Northumbria University, UK. This is her seventh deployment to Antarctica, and she has also carried out fieldwork in Greenland, Svalbard, the Himalayas, and the European Alps. Ali is the CU Boulder PI and overall fieldwork lead for this project. She brings particular expertise in GNSS, automatic weather stations, and time-lapse photography, and leads the project’s satellite remote-sensing component. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/9189da9b-b792-4bff-9708-84b60077d229/AWS_temp_20251223_20251227.png Field Blog - Antarctic Field Work - 2025/26 - Make it stand out Air Temperatures: Overall temperatures in the Rumple Zone are below freezing for the short record so far. Despite the 24-hour sunlight here, the temperatures fluctuate diurnally – meaning the warmest temperatures generally occur during the day and cooler temps at night; this is due to the sun’s angle in the sky throughout the day. Temperatures are also generally consistent between the crest (blue) and trough (orange); however, the crest tends to warm earlier in the day. This is because the trough sensors are, at times, shadowed from the sun’s angle in the sky from the height the rumple crests; thus, experience a delay in surface warming. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/f8a09759-3eb5-4bed-8f88-4317e7939cd2/DSC07412._red.jpeg Field Blog - Antarctic Field Work - 2025/26 - AWS Iceberg Allie and Tech and Snowpit Extraordinaire Michela admiring the fruits of their labor with the AWS station. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/84ac49c6-0e4e-4a37-ac08-d9b6615345f2/IMG_1578_annot_red.jpg Field Blog - Antarctic Field Work - 2025/26 - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/537a0501-bff9-4fa1-9e0b-1d483bd1c3d4/IMG_1562.jpg Field Blog - Antarctic Field Work - 2025/26 - ApRES Installation UMaine PhD student Allie Berry configuring the ApRES to conduct measurements within the ~30 meter thick ice shelf. Specifically, we are looking for changes related to englacial meltwater, englacial strain rates, and potentially the brine aquifer – a layer of cold saline water stored within the ice shelf. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/a48bb941-abcb-4ceb-8721-5bc4bdbe797c/AWS_WindSpd_20251223_20251227.png Field Blog - Antarctic Field Work - 2025/26 - Make it stand out Wind speeds between the crests and troughs also track consistently. The undulating surface provides a small buffer from the wind in the troughs as opposed to the exposed surface along the crests. As anyone on our team can attest, one can definitely feel the difference in wind speed when working on top of the crests vs the rumple troughs. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/e4b1d156-bf01-45e6-b068-74e106dfc0b4/Rumple_sample_annot2_red.jpg Field Blog - Antarctic Field Work - 2025/26 - Make it stand out A *preliminary* scan down a trough with the ice shelf front towards the right of the image. The plot shows the ice shelf stratigraphy as subsurface depth (vertical axis) and distance along the profile (horizontal axis). A couple of interesting features are evident. A bright horizontal layer appears beginning ~8 meters depth and shallows to ~2 meters depth at ~80 meters along the profile. This is a suspected brine layer – a salt rich firn layer and/or salt-rich meltwater layer. The second interesting feature is the parabolic shape ~10 m deep and 60 m along the profile; this is a crevasse. We will use GPR data on the brine layer, crevasses, and potentially folds in the ice to understand the dynamics driving Ice Rumple evolution and stability. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/878bdf30-08fe-4e19-9cad-1215010da1c9/DSC07651_red.jpeg Field Blog - Antarctic Field Work - 2025/26 https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/f7135488-2422-4318-bebe-4a8d279d370c/IMG_1564.jpg Field Blog - Antarctic Field Work - 2025/26 - As Assist by the FS&T Team Special shout out to FS&T mountaineers Dylan (left) and Lauren (right) for guiding us safely through the Rumple Zone. Their expertise anchoring in snow/ice also comes in handy for securing equipment to the ice shelf as shown here securing the ApRES battery box and solar panel using an ice anchor on top of a rumple crest. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/f8db5a7d-ca64-4dc1-8332-e9a2fec72074/Rumples_red.jpg Field Blog - Antarctic Field Work - 2025/26 - Dec 4, 2025: The McMurdo Ice Shelf We recently started an US National Science Foundation collaborative project to study the Rumple Zone of the McMurdo Ice Shelf, Antarctica. In some areas - including our field site at the edge of the McMurdo ice shelf besides Ross Island - ice shelves are under compression, where the ice shelf is flowing over ocean towards land. In this environment, an ice shelf can crumple, forming topographic features in the ice shelf that look like rumples or waves. In the some cases, the glacier ice within these rumples can also buckle, forming fractures, orientated either perpendicular or parallel to the ice shelf flow. The overall goal of our project is to determine how rumples affect ice shelf stability and hence ice shelf buttressing power, i.e. how much an ice shelf can slow the flow of grounded ice behind it. To do this, we first need to understand how the rumples evolve over time and the geophysical mechanisms governing their formation and stability. This is a collaborative project between the universities of Chicago (PI Doug MacAyeal), Colorado-Boulder (PI Ali Banwell, me Co-PI Ryan Cassotto), and Maine (PI Kristen Schild and Co-PI Seth Campbell). https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/0faa2929-fed7-43ce-8b06-a1ffe69ba220/4E8FA302-EBB2-4CF0-A95C-392278F5DC19IMG_1672.jpg Field Blog - Antarctic Field Work - 2025/26 - Michela Savignano - CU PhD Student Michela (aka. Tech and Snow Pit Extraordinaire) is a PhD student in the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder. Her research focuses on ice shelf stability and how it is impacted by increasing surface melt. She uses both optical and lidar remote sensing data to study these changes and is interested in how they will impact global sea level in a warming world. On the rumple project, Michela is in charge of making really awesome GoPro time-lapse videos (this blog), taking care of Wall-E (our other time lapse camera), tech support (obviously), digging gigantic holes in the snow (see photo), and any and all other miscellaneous tasks. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/0f695f7f-c751-4bfe-abd3-835707cdc75f/IMG_0461_red.jpeg Field Blog - Antarctic Field Work - 2025/26 - Dec 8, 2025 - Touchdown!

We completed no less than 10 such trainings including field safety and survival, multiple field risk assessments, VHF and iridium satellite phone communication, GPS training, working in and around helicopters, driving station vehicles, stove/heater training, and operating snow machines and PistenBulleys (aka. Snow groomers). After a week of training and a few weather delays, we installed base stations for our TRI and time-lapse cameras on a hillside above the Rumple Zone. A major shout out to the very talented crew of Carpentry Operations or “Carp Ops” – particularly “Stitch” and Mark for building and installing these base stations. Their hard work has made our job so much easier – allowing us to focus on the science here in Antarctica. https://images.squarespace-cdn.com/content/v1/5fd846edeaa78e7fb36da718/2e657777-caa1-47ec-a7b9-c7fef90952ea/IMG_0579_red2.jpg Field Blog - Antarctic Field Work - 2025/26 - Dr. Ryan Cassotto - Field Team Co-PI Ryan (aka. Penguin Ambassador) is an Assistant Research Professor in the Climate Change Institute at the University of Maine and a Research Scientist in CIRES at the University of Colorado.

In particular, I used a terrestrial radar interferometer (TRI) to characterize and understand how short term perturbations at the ice-ocean boundary affected ice dynamics along the terminus. I also used thermal infrared observations of the sea surface to assess how variations in winter ice melange impacted calving and the seasonal location of glacier calving fronts.
