Natalya and I caught up when she came to visit Dartmouth for an Earth Science colloquium.

elizabeth burakowski

Liz and I caught up when she came up to Dartmouth to give an ice+climate seminar [https://sites.google.com/dartmouth.edu/ice-climate] in winter 2024. We talk about snow and climate change in the Northeast. We talk about Liz's recent work on ice climbing as an indicator of warming winters [https://doi.org/10.3389/fhumd.2023.1097414 [https://doi.org/10.3389/fhumd.2023.1097414]]. We reference the "snow cliff" as described by Gottlieb and Mankin (2024) [https://doi.org/10.1038/s41586-023-06794-y [https://doi.org/10.1038/s41586-023-06794-y]] which had recent been published. Liz and I talk about the great work that Mardi Fuller is doing here in New Hampshire. In particular, Liz recommends the film Mardi and the Whites [https://www.paulachampagne.com/mardiandthewhites] We also touch on Liz's work with Protect Our Winters [https://protectourwinters.org/ [https://protectourwinters.org/]] and Community Snow Observations [https://communitysnowobs.org/ [https://communitysnowobs.org/]].

dan goldberg

I caught up with Professor Dan Goldberg [https://dngoldberg.github.io/] when he was on sabbatical here at Dartmouth in 2023. We talk about the Geophysical Fluid Dynamics program (https://gfd.whoi.edu/) [https://gfd.whoi.edu/)] and grounding lines (the location where ice sheets begin to float on the ocean as an ice shelf; Schoof, 2007 [https://doi.org/10.1017/S0022112006003570] and Goldberg et al., 2009 [https://doi.org/10.1029/2008JF001227]). In our discussions about inversions, I mention the work by Bueler and Brown (2009) [https://doi.org/10.1029/2008JF001179].

gwenn flowers

Gwenn Flowers [https://en.wikipedia.org/wiki/Gwenn_Flowers] visited Dartmouth College in Winter 2023 as part of the Society of Fellows invited speaker series. We talk about the International Glaciological Society [https://www.igsoc.org/] (IGS) where Gwenn is the current president. She dicusses recent IGS efforts on Diversity, Equity, and Inclusion (DEI) as well as the IGS global seminar [https://www.youtube.com/c/InternationalGlaciologicalSociety/videos] that Tavi Murray started in the beginning of the pandemic. This has been an excellent resource for learning about work in the community in a virtual format. Gwenn offers advice about protecting time, teaching strategies, and taking baby steps. We talk a lot about Gwenn's experience as a student and her thesis advisor Garry Clark [http://142.103.43.13/news-events/news/1647414000]. Gwenn's brings excellent insights on mentoring and the kind of mentoring she received from Garry, Helgi Björnsson [https://www.igsoc.org/about/awards/honorary-membership/helgi-bjornsson], and Carl Wieman [https://profiles.stanford.edu/carl-wieman?tab=bio]. We discuss the current place of fieldwork in glaciology: the attraction for students, the future of remote sensing, and training tool. We also tie fieldwork into our earlier discussion of DEI (e.g., Karplus et al., 2022 [https://doi.org/10.1017/aog.2023.32]) and we talk about the privelege of field work (e.g., the 40 years of no progress on diversity paper authored by Bernard and Cooperdock, 2018 [https://doi.org/10.1038/s41561-018-0116-6])

lauren andrews

Lauren Andrews [https://science.gsfc.nasa.gov/sci/bio/lauren.c.andrews] and I caught up in January 2024 when she visited Dartmouth to give an ice+climate seminar [https://sites.google.com/dartmouth.edu/ice-climate] as well as work on an ICESat-2 collaborative project. Much of conversation focused around subglacial hydrology, the flow of water under glaciers and ice sheets. In particular, we discuss the field campaign that she worked on as a graduate student. The result of this fieldwork was published in her 2014 Nature paper [https://doi.org/10.1038/nature13796]. A few names of folks that appear numerous times throughout the show are * Bob Hawley [https://faculty-directory.dartmouth.edu/robert-l-hawley], Dartmouth College * Martin (Tinu) Lüthi [https://www.geo.uzh.ch/~mluethi/], University of Zurich * Matt Hoffman [https://www.lanl.gov/search-capabilities/profiles/matthew-hoffman.shtml], Los Alamos National Laboratory I also mention the borehole catalog that I am compiling. In this project, I am collecting borehole observations of subglacial effective pressure (the difference between ice overburden and water pressure). The goal is to understand the distribution of effective pressure below glaciers (figures 1 and 2) and to constrain subglacial hydrology models. The data catalog is stored as a google sheet [https://docs.google.com/spreadsheets/d/1S-USi6L5FRTbCofL0S2lyNDCO-vAV7kJ0tTB_jJ-fTM/edit?usp=sharing]: please be in touch if you have data to add to the catalog!
