Arrived at a distant hut — first open the hut, fire and snow clearing. Slowly, warmth returns after a day in minus 20.
Svalbard fieldwork blends presence of harshness, long hours with awe. Even with a busy mind, the beauty is hard to be unnoticed.

All is reflection.
Every action ripples back.
The choices we make —
their shine hides a shadow.
Consumerism glitters,
but the cost
is buried deep in soil and sea.
One day we will be surprised —
surprised because we did not see
the reflections,
the causes,
the links
woven through everything.

#Refreezing
#SurfaceRunoff
❄️👉💧
Current measurements and models often overestimate how much meltwater from Greenland’s ice sheet enters the ocean because they miss key retention processes.
Much meltwater refreezes in porous ice or ponds, cutting actual runoff by 9–15% compared to older estimates.

Brown-affiliated studies help explain overestimations in impact of Greenland Ice Sheet melting
Two studies noted that current measurements and simulations may not adequately consider processes that retain meltwater.

Did meltwater from circum-Arctic ice sheets trigger AMOC weakenings during past deglaciations? We think that we can present a convincing line of evidence, from the central Arctic to the North Atlantic. See our recent paper in QSR:

Here's a closer look at the record low sea ice conditions around #Svalbard. The ice edge is still close to the 85°N line of latitude along the Atlantic front. That's a lot of open water into the Barents Sea region! Data from AMSR2.

Our new paper compares GPR ice thickness data with models and looks at glacier thermal structures in Greenland, showing that thermal complexity (warm-cold ice) inside these glaciers is higher than expected.
