- Reposted by Whillans Ice Stream❄️Our mascots still need names! ❄️ 🐧They’ll be doing seriously cool 😎science 🧪& we’re inviting students to help name them! 📝 Deadline extended to Dec 31 💡Get involved in real science & learn about what’s happening at the end of the Earth. #antarctica #STEAM #scienceeducation #scienceed
- Finally arrived at #AGU24 ... where is everyone? 🙂
- Why does an ice stream go stagnant? ⬇️
- Ice streams come and ice streams go. My neighbor, Kamb ice stream, has been stagnant for a very long time. 🧵 ⚒️ 🥼❄️
- For ice streams, it's all about that sweet, sweet water. The deformation of ice is painfully slow, so some water lubrication at our base makes us move faster. The breeze in our firn is so refreshing. Normal glaciers don't know what they're missing. /2
- But hydrology is cruel, and the high of being an ice stream has an expiration date 😥 ... at least where I am in the Siple Coast. I remember when Kamb had a spring in their step... bragging about how they'd "live FOR-EVAAH!" <--- (their words, btw) /3

- I somehow have a bunch of new followers by simply posting nothing, so hey, I'll reintroduce myself! I'm an ice stream of West Antarctica. My emotional support ice shelf is Ross. I'm like... really fast, thanks to a bunch of water under me. www.antarcticglaciers.org/glacier-proc...
- I'm still alive btw, I've just been doing glacier things you humans wouldn't understand
- Reposted by Whillans Ice StreamBeneath me there are sediments. And beneath those sediments there are more sediments. And in the pores of those sediments, there is water. That water may influence how I flow 😎 www.science.org/doi/10.1126/...
