Sediment transport by Greenland’s icebergs - Nature Communications
Greenland’s icebergs transport 450 megatonnes of sediment to its fjords each year, representing one-third of the ice sheet’s total sediment export. This ice-rafted debris builds shoals at tidewater gl...

Still really dry in Colorado. Current snow pack in the Colorado Headwaters, the black line, is 57% of 30y reference. Gonna try to ski this weekend, we'll see.

Missed this thing even if I care about sand. But love the zoom-out and thinking about the fundamental part of science; to be willing to be wrong, to be willing to listen to conflicting evidence.
The whole "sandgate" thing that happened yesterday on Bluesky was pretty fun. I wrote a blog post with some deeper thoughts on this, and why it is important for scientists to have humility. raisedbeaches.net/2026/01/29/s...
Sandgate

As sea ice retreats, waves matter more. Models show wave events resuspend sediment on the Beaufort Sea shelf, reversing net transport westward despite eastward currents. This affects coastal change & carbon fate in the Arctic. Read more: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Prairie around us is so wind-scoured after the storm events of this early winter. It's been dry since October and this is an area with a large prairie-dog colony - so more sparsely rooted and vegetated. I estimate we lost several cm's of topsoil.
