Ice sheets as a significant source of highly reactive nanoparticulate iron to the oceans [PDF]
, 2014 The Greenland and Antarctic Ice Sheets cover ~\n10% of global land surface, but are rarely considered as active components of the global iron cycle. The ocean waters around both ice sheets harbour highly productive coastal ecosystems, many of which are ...

Behavioral Response Study on Seismic Airgun and Vessel Exposures in Narwhals
Frontiers in Marine Science, 2021 One of the last pristine marine soundscapes, the Arctic, is exposed to increasing anthropogenic activities due to climate-induced decrease in sea ice coverage. In this study, we combined movement and behavioral data from animal-borne tags in a controlled

Effect of ice sheet thickness on formation of the Hiawatha impact crater [PDF]
, 2021 The discovery of a large putative impact crater buried beneath Hiawatha Glacier along the margin of the northwestern Greenland Ice Sheet has reinvigorated interest into the nature of large impacts into thick ice masses. This circular structure is relatively shallow and exhibits a small central uplift, whereas a peak-ring morphology is expected.

Coherent Control of Rydberg States in Silicon [PDF]
Nature, 465, 1057-1061 (24 June 2010), 2010 We demonstrate coherent control of donor wavefunctions in phosphorous-doped silicon. Our experiments take advantage of a free electron laser to stimulate and observe photon echoes from, and Rabi oscillations between the ground and first excited state of P donors in Si.
