2023 Fall

IDP is providing support to the following projects during the 2023-2024 Antarctic field season:

(1) The STC Integrative Partnership: The Center For Oldest Ice Exploration (COLDEX): Shallow Ice Coring project (PI Ed Brook; NSF award 2019719; Field lead Sarah Shackleton (I-187-M)) will use the Blue Ice Drill and the Badger-Eclipse Drill to drill several cores between 80 and 160 meters deep from the Allan Hills Blue Ice Area. Cores drilled through the Antarctic ice sheet provide a remarkable window into the evolution of Earth’s climate and unique samples of the ancient atmosphere. The clear link between greenhouse gases and climate revealed by ice cores underpins much of the scientific understanding of climate change. Unfortunately, the existing data do not extend far enough back in time to reveal key features of climates warmer than today. The cores collected at Allan Hills will contribute to our understanding of how Earth’s climate system operated during warmer periods and why the periodicity of glacial cycles lengthened from 40,000 to 100,000 years approximately 1 million years ago.

(2) The NSF-NERC: Ground Geophysics Survey of Thwaites Glacier project (PI Sridhar Anandakrishnan; NSF award 1738934; C-442-M) will conduct its final field season in the Thwaites Glacier region of West Antarctica. The project will conduct seismic and radar surveys along transect lines parallel and perpendicular to the flow of Thwaites Glacier. Based at WAIS Divide, they will separate into teams collecting different measurements. The Vibroseis and Active traverse team will move along transect lines while acquiring radar data and conducting active source seismic surveys. The Passive seismic team will recover Earthscope SAGE-provided nodes at GHOST Subglacial Ridge. The ApRES and Delores teams will collect radar measurements along the parallel Thwaites Glacier transect line, conduct Magnetotelluric measurements, and retrieve radar/GPS stations deployed in the area during the previous season. The Vibroseis and Active traverse team will use the Rapid Air Movement (RAM) Drill to create the shot holes required for the seismic measurements.

(3) The RAPID: US-Korean Collaboration to Build a Ross-Amundsen Ice Core Array (RAICA) Along the West Antarctic Coastline project (PI Peter Neff; NSF award 2304836; I-345-M) aims to recover a ~100 meter long ice core from an ice rise in the Amundsen Sea region of coastal West Antarctica. The ice core will be used to reconstruct annual climate and environmental variability over the past 200-400 years, constrain surface mass balance variability and trends over the (pre)instrumental period, and contribute greater temporal perspective to ongoing investigations of Thwaites Glacier – an extensive system that will contribute significantly to global sea level rise for centuries to come. This project collaborates with Korean Polar Research Institute (KOPRI) scientists and is supported via the KOPRI icebreaker RV ARAON. Martin Peninsula, between the Getz Ice Shelf and the Dotson Ice Shelf, has been chosen as the primary site based on existing airborne snow radar data and the high snow accumulation rate, which preserves high-resolution paleoclimate information. The specific drill site will be chosen based on scientific value and logistical constraints associated with the RV ARAON cruise.

(4) The Sea-Ice Snow Microbial Communities’ Impact on Antarctic Bromocarbon Budgets and Processes project (PI Karen Junge; NSF award 2031121; B-321-M) will test if bromocarbons in sea ice are produced and degraded by microalgae and bacteria found in sea ice, snow, and the interface between the two. The researchers will use a Kovacs Hand Auger to drill several cores (up to 24) through ~2.5 meters of sea ice twice per week for six weeks. The cores will be used to collect chemical and biological measurements of sea ice and snow to determine bromocarbon concentrations, microbial activity associated with them, and intra-cellular genes and proteins involved in bromocarbon metabolism. Bromocarbons are known to contribute to stratospheric ozone depletion over Antarctica. This project will test if they are produced and degraded by algae and bacteria found in sea ice, snow, and the interface between the two.

(5) The CRREL Support to the Leverett Glacier project (PI Renee Melendy; T-941-M) involves a ground campaign utilizing ground penetrating radar (GPR) surveys to validate remote sensing imagery to find a less crevassed route to Leverett Glacier. As part of the fieldwork, the team will collect snow property data (snow density and hardness) to determine best-practice snow bridge crossing criteria for the area and ice velocity movement data using GPS station installations. The team will have an IDDO Hand Auger with them.

(6) The Cold Regions Research and Engineering Laboratory (CRREL) Activities: McMurdo Shear Zone project (PI Renee Melendy; T-940-M) will provide annual shear zone crevasse detection and mitigation for the South Pole Traverse (SPoT). The team will have an IDDO Hand Auger with them.

(7) The Collaborative Research: Site Survey for Subglacial Bedrock Exposure Dating at the Margin of the Wilkes Basin in Northern Victoria Land project (PI Greg Balco; NSF award 1744844; I-158-M) aims to establish, through direct geological evidence, whether complete deglaciation of East Antarctic marine basins took place during past warm-climate periods. The researchers will assess the feasibility of achieving this goal using cosmogenic-nuclide measurements on bedrock buried under the ice sheet. During the single field season (2023-24) reconnaissance and site survey, the researchers will conduct snowmobile-towed radar surveys, geologic mapping, and rock/sediment sampling at several sites in the western Outback Nunatacks region of northern Victoria Land. The researchers will also have a Kovacs Hand Auger with them.

Assembly of the new 700 Drill is in full swing at IDP in Madison, WI. Mechanical assembly of the sonde is nearly complete, from the anti-torque section down to the cutter head. The control box and console are currently being wired, and electronics testing is underway. Shipping cases were ordered and received, and designs for the core handling and fluid/chips processing systems are now complete.

IDP Engineers revisited the Deep Logging Winch to mitigate electromagnetic interference (EMI) issues previously witnessed in the field with several logging tools provided by community scientists. Through careful investigation and comparison with a winch at the UW Physical Sciences Lab, noise and communication lapses have been successfully mitigated by installing two filters and cleaning of slip ring contacts. The winch is now ready for issue.

Good progress is being made in preparing the Winkie and ASIG drills for the second season of the GreenDrill project in northeast Greenland in spring 2024. Maintenance was completed on the Winkie Drill packer and drive head and air compressors for the Winkie and ASIG drills. New core barrel components were ordered, received, and tested for the Winkie Drill to improve clearances when drilling in clay and mixed media, and a new slip foot clamp was implemented and tested.

The U.S. Ice Drilling Program (IDP) will hold the AGU Town Hall on Scientific Drilling in the Polar Regions on Thursday, 14 December 2023, from 13:00-14:00 Pacific Standard Time (PST) in room 2004 – West (Level 2, West, MC) of the Moscone Center, San Francisco, CA. We hope to see you there!

Abstract: Ice sheets, glaciers, and the underlying bedrock, sediment and permafrost hold crucial evidence of past climate, ice sheet dynamics, and cratonic geology. National and international collaboration for drilling in the remote Polar Regions requires strategic coordination between science, technology, and logistics. This meeting will provide the scientific research community with brief updates from IDP, Ice Core Young Scientists (ICYS), International Partnerships in Ice Core Sciences (IPICS), GreenDrill, Hercules Dome, and Rapid Access Ice Drill (RAID). Opportunities for community involvement will be showcased, and input from the audience will be solicited.

With access to the polar ice sheets beginning to open following the pandemic years, the Science Advisory Board of the U.S. Ice Drilling Program (IDP) has recommended that the Subglacial Access Working Group (SAWG) and Borehole Logging Working Group (BLWG) cease as separate groups. Instead, a single new working group, the IDP Englacial and Subglacial Access Working Group (ESAWG), is being formed. The ESAWG will provide an opportunity to develop and articulate new visions for U.S.-led englacial and subglacial science for the coming decade in the IDP Long Range Science Plan.

The following 2023 AGU Fall Meeting presentations have IDP leadership, engineers, or drillers as authors or co-authors.

Two of IDP’s 2023 Train the Trainers workshop participants, Susan Rubert and Marc VanKeuren, are presenting IDP’s newest Virtual Field Lab featuring Drs. Karen and Richard Alley at the Fall 2023 AGU Meeting on Tuesday, 12 December 2023. Virtual Field Labs are unique interactive education and outreach products designed for students from late middle school to college.

A Perspective article published in Nature Geoscience tackles the longstanding issue of gender representation in science, focusing on the field of ice core science. Prior work has shown that despite progress toward gender parity over the past fifty years, women continue to be significantly underrepresented within the discipline of Earth sciences and receive disproportionately fewer opportunities for recognition, such as invited talks, awards, and nominations. This lack of opportunity can have long-term negative impacts on women’s careers. To help address these persistent gender gaps, the study evaluates patterns related to women’s publication in ice core science over the past fifty years. The study was co-led by Bess Koffman of Colby College, USA, and Matthew Osman of Cambridge University, UK, and coauthored by Alison Criscitiello and Sofia Guest, both of the University of Alberta, Canada.

To assess relationships among gender, publication rate, and impact of coauthor networks, the study evaluates a comprehensive, global dataset of abstracts representing published work in ice core science spanning 1969 to 2021 in this historically male-dominated discipline. The Perspective article shows that the inferred gender gap in ice core science has declined from roughly 10:90% women:men in the 1970’s to ~30:70% in the past decade. Contrasting with prior work across the sciences, the authors find that women’s and men’s coauthor networks have remained similarly sized and been similarly cited through time. This finding may reflect the high degree of international cooperation and the large collaborative teams that are typical of the field of ice core science.

Importantly, the gender makeup of coauthors differs substantially for man vs. woman-led studies. Strikingly, within the past decade, woman-led studies have contained on average 20% more women coauthors than man-led studies, a difference found to be even greater in earlier decades. Moreover, since the early 2000s, the analysis shows that women have out-performed by about 8% their estimated proportion within the ice core community in terms of publishing first-authored papers. The new analysis by Koffman, Osman, and colleagues suggests that senior women in particular catalyze women’s participation in publishing, and that collaboration between women can help close gender gaps in science.

This collaborative effort by the authors emerged from the first Ice Core Early Career Researchers Workshop (ICECReW).

The third annual US Ice Core Open Science Meeting will be held May 15-17, 2024, at the Portland Public Library in beautiful Portland, Maine. The NSF-funded Hercules Dome Ice Core Project is convening the meeting.

This meeting is intended for anyone interested in ice core science or related fields, including ice-core analysis, ice or subglacial drilling, glacier geophysics that supports or depends on ice core records, paleoclimate, and contemporary climate and ice sheet change.

The goals of the meeting include:

1. Sharing the latest science.
2. Discussing future ice core and related science projects in both polar regions and alpine environments.
3. Providing career development opportunities.
4. Improving communication about ice-core and related science within and beyond the scientific community.

We hope to attract a diverse group of participants, including those who may not have extensive experience working with ice cores.

While this meeting is primarily oriented toward researchers in the US, international colleagues are welcome to attend.

The meeting will begin midday on Wednesday, May 15, and end in the late afternoon on Friday, May 17. The meeting will be preceded by an Ice Core Early Career Researchers Workshop (ICECReW) for early career researchers focused on applying for academic and alt/ac jobs.

Details on hotel rooms, travel support, and other aspects of the meeting will be publicized in February.

The third Ice Core Early-Career Researchers Workshop (ICECReW) will be held on May 14 and 15, 2024, at the Gulf of Maine Research Institute in Portland, Maine, ahead of the US Ice Core Open Science Meeting (May 15-17). ICECReW is an opportunity for early-career researchers to meet and discuss ice-related science. The theme of this year’s workshop is exploring career opportunities within and outside of academia. The workshop will focus on developing and receiving feedback on application materials such as CVs, research statements, teaching statements, and cover letters.

ICECReW is intended for early-career researchers whose work contributes to polar sciences or paleoclimatology. We broadly define “early career” as someone within three years of PhD (before or after completion), although exceptions are certainly possible.

Please join the Hercules Dome mailing list to ensure you receive all the meeting announcements.

More details for the workshop will be announced in early 2024. We anticipate supporting the cost of an additional two nights’ lodging for US participants. Travel to/from the US Ice Core Science Meeting may be partially supported depending on need.

The deadline for submitting the ICECReW application is February 9, 2024.
