In Memory of Laurie Padman (Laurence Padman)

Earth and Space Research (ESR) is sad to announce the passing of our dear friend and colleague Laurie Padman on Tuesday, October 6, 2026.

After a decade at Oregon State University, Laurie joined ESR in 1997. He began his career in polar sciences as a postdoc working on Arctic turbulence and was hooked on cold climates after doing fieldwork in an Arctic ice camp in 1989. He joined ESR for a chance to contribute to Gary Lagerloef and Robin Muench’s collaborative vision while continuing to study polar oceans and ice. He ushered in and created ESR’s reputation and capability in polar sciences. He also played a major role in ESR’s growth and management, serving as Vice President (2011-2019), President (2019-2024), and on ESR’s Board of Directors (2011-2026).

Carrying out research in both the Arctic and Antarctic, Laurie was a trailblazer in ocean, sea ice, and ice shelf interactions and an early investigator of ice sheets and ocean circulation beneath Antarctic shelves. In his early career, he made two field trips to the Arctic, measuring turbulence and mixing from research camps set up on floating sea ice. His first Antarctic field trip was on a joint US/Russian ice camp in the western Weddell Sea in 1992, closely following the 1915 drift of Shackleton’s ill-fated ship Endurance. He participated in five other Antarctic cruises between 1994 and 2005. During Laurie’s nearly four decades in polar science, his work transitioned from turbulence measurements and fieldwork to modeling and satellite-based climate studies. Laurie was recently a member of NASA’s ICESat and ICESat-2 science teams, and a collaborator on SWOT and the upcoming EDGE missions. Laurie’s contributions to topics such as polar tides, ice shelf tidal flexure and basal melt processes continue to have significant and enduring influence on the field.

Laurie’s departure from this world leaves a huge void in the field of Earth sciences. Throughout his career, Laurie selflessly worked alongside others and mentored dozens of students and early-career researchers, inspiring the next generation to further our understanding of the oceanic and ice processes acting in the marine cryosphere. He also engaged in his role as editor at Journal of Geophysical Research (Oceans) with great passion and dedication, ensuring quality and valuable scientific publications. Reflecting his life’s journey and his collegiality, Laurie’s research collaborations were globally distributed from his home country of Australia, to the US, the UK, and Europe. Laurie's impact has been vast and widespread.

Laurie was a role model for all of us; the epitome of an ethical, caring, brilliant scientific researcher, using his deep intellectual curiosity and rigor, combined with enthusiasm, passion, and wry sense of humor to further polar science, all while lifting others up. He invested so much time in every single thing he worked on, and documented it all to perfection, sometimes to the frustration of his co-authors. We are all going to miss him so terribly, but his legacy will always remain.

A new paper led by ESR’s Susan Howard shows that the NASA/CNES “SWOT” satellite, designed for surface water and ocean topography studies, can also measure changes in the Antarctic ice shelves.

Antarctic ice shelves can act as brakes on ice loss from the massive Antarctic ice sheet. Understanding the processes that affect the ice shelves are critical to our understanding of potential sea level rise.

SWOT, which uses radar interferometry to measure swaths of surface height every 21 days regardless of clouds, can detect tidal flexure, monitor vertical ice shelf motion, and measure crevasse changes, helping us understand processes affecting ice shelf stability.

Check out the open access paper:

ESR was happy to join in the fun at Ridgecrest Elementary's STEAM night on March 26, 2026. ESR's Susan Howard and Julian Schanze, with help from Amelia Ebling and K. Schanze, led students through an exploration of density and demonstrated how it relates to the ocean. We are looking forward to our next event on April 22, 2026 - Earth Day 🌎.

ESR is happy to share the exciting news that the Earth Dynamics Geodetic Explorer (EDGE) has been selected as one of two new satellites in NASA’s Earth System Explorers program. EDGE is a swath-mapping laser altimetry mission led by Professor Helen Fricker at Scripps Institution of Oceanography, and may launch as early as 2030. ESR senior scientist Laurie Padman is an EDGE Project Partner and will contribute to development of algorithms for EDGE’s applications to ice sheets, sea ice, and oceans.

Parts of the Antarctic Ice Sheet stick to the bed most of the time but lurch forward once or twice per day, synchronized by the ocean tides. A new paper by Zachary Katz, a PhD student at the Colorado School of Mines, co-authored by Mines advisor Matt Siegfried and ESR’s Laurie Padman, shows the importance of accounting for long-period tidal variability when analyzing ice motion and mass loss from the ice sheet.

We created an 11-year (2008–2019) catalog of stick-slip events on Whillans Ice Plain (WIP) in West Antarctica GNSS-derived mean horizontal velocity of WIP correlates with tidal forcing at fortnig...

This month, ESR's spotlight is on The Mount Baker Project. This Citizen Science project started from a high school mountaineering trip and has become a long-term climate research project, under the direction of Michael Town.

The program, which has produced tangible scientific insights while inspiring dozens of students, demonstrates that actionable science isn’t limited to large institutions or costly infrastructure - it can grow from curiosity, collaboration, and commitment to shared data and open science.

We would like to thank our partners, Lakeside School and the San Diego Foundation, for contributing to this program financially and through in-kind effort. This project has truly been a Citizen Science collaboration!

For more information, also check out our Mount Baker Climate Laboratory GitHub (https://esr-mbcl.github.io/MBCL/) which serves as the central science collaboration site for this project.

We’re excited to celebrate the successful completion of the Earth and Space Research and Northeastern University (https://seattle.northeastern.edu/) partnership, showcased last week at the NU Expo. Through this collaboration, ESR scientists (Kathleen Dohan and Michael Town) mentored two student teams, nine students total, on applied machine learning projects that connect data science directly to real-world Earth system challenges.

Project 1: Integrated Machine Learning Modeling of Atmospheric Drivers for Understanding and Predicting Energy Transfer

This ML/AI project focused on predicting snow surface temperatures at Summit, Greenland using only local meteorology and cloud properties. The work supports improved understanding and prediction of melt conditions in one of the most rapidly changing regions of the cryosphere.

Students: Cheng-Wen (Eric) Hsu, Ya (Jaelyn) Ji, Zerui Li, Mohit Chhabria, Surya Shivam

Project 2: Ocean Current Forecasting using Machine Learning

This ML/AI project used regional meteorology and ocean current data to produce 1–3 day forecasts of ocean currents off the west coast of Washington. Applications include regional fisheries, coastal planning, and understanding pollution transport pathways.

Students: Ming-Hsiang Lee (Thomas), Qing Wen, Shuxin Yang, Laxmi Bhutani

We are incredibly proud of the students for tackling complex, interdisciplinary problems and translating machine learning techniques into actionable environmental insights. This partnership highlights the power of mentorship, applied data science, and collaboration between research organizations and universities.

Thank you to Northeastern University and all involved for a fantastic collaboration. We look forward to what comes next!
