Ice sheets and climate • PhD candidate studying Thwaites Glacier @CUBoulderATOC • she/her/hers
Boulder, CO
Joined July 2013
Stoked to share my paper on #atmosphericrivers in #WestAntarctica and their impacts on snowfall and melt! We use observations, reanalysis, and firn modeling to examine an AR family (series of 3 ARs) that occurred over #ThwaitesGlacier in February 2020! https://t.co/HP39Kl4neE
tc.copernicus.org
Abstract. Atmospheric rivers (ARs) transport large amounts of moisture from the mid- to high-latitudes and they are a primary driver of the most extreme snowfall events, along with surface melting,...

The meteorology community does not really understand how bad things are going to get. And frankly, neither do I. https://t.co/U3S6xDhgBu

Happy 22-year anniversary of the March '03 blizzard! 31.2" fell in Denver, the city's 2nd-biggest storm on record. Over 60" (!) fell in the foothills. DIA closed, 135k people lost power, and the snow created a huge gash on the @DENAirport roof. What are your memories? #COwx

Looking forward to giving this lecture at the Longmont Museum!
Happening Thursday! If you're in #Colorado, come out to the Longmont Museum for an encore presentation of the Explorer Series lecture about atmospheric rivers with Christine Shields. It's sure to make a splash! 💦 Details and registration: https://t.co/MrOY37kdyS

Not just #NorthernLights. This from the South Pole! We're seeing amazing pictures from London, Switzerland, Austria--even in bright cities. Skies in NE Colorado and nearby areas will gradually clear this evening. This may be the best chance to see the aurora here in 20 years.

Awesome new study with a head-to-toe analysis of the East Antarctic heatwave 🇦🇶🌡️❄️ in March 2022. Congrats @JonathanWille for leading this huge, interdisciplinary effort!

What causes the bumps and wiggles in time series of Antarctic ice-mass change, and how do they relate to large-scale climate modes and ice sheet trends? That's what we look at in our new paper in @NatureGeosci with @KeweiLyu @Xuebin_Zhang 🧵 1/n https://t.co/xbGGY6BaMY

Our paper is out! Melting of glacier ice enhanced by bursting air bubbles | Nature Geoscience
nature.com
Nature Geoscience - Laboratory experiments suggest that bursting bubbles enhance ice melt from tidewater glaciers, and consequently, glacier-ice structure needs to be accounted for in projections...

You’ve heard about Antarctic sea ice lows - well, here’s the consequences. Over 9,000 emperor penguin chicks from colonies in the Bellingshausen Sea are thought to have died in November 2022. The sea ice they lived on broke up early, before they'd developed waterproof feathers.

The Boulder edition of the #AntarcticAtmosphericRiverWorkshop was fantastic this week! Excellent talks and conversations about current unknowns/gaps in the research. Already can’t wait for next year!! 🌨️#antarctica #atmosphericriver
Thinking about Antarctic #AtmosphericRivers with a fabulous bunch of scientists at the #AntarcticAtmosphericRiverWorkshop in Boulder. Great science, discussions, community, and fun! @MLMaclennan @tridatta1 @acwinters_wx @BeccaBaiman @CUBoulderATOC @NCAR_CGD @UGrenobleAlpes

🚨 My first, first-author paper has been published in @EGU_TC! ❄️ Co-authors Nander Wever, Max Stevens, @lenaertsjan, @DrBrookeMedley, and I evaluated and compared two firn models on the Greenland Ice Sheet. Check out what we found here:
tc.copernicus.org
Abstract. The Greenland Ice Sheet's (GrIS) firn layer buffers the ice sheet's contribution to sea level rise by storing meltwater in its pore space. However, available pore space and meltwater...
