Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to Rutgers scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to a Rutgers-led study – the first of its kind – in the journal Geophysical Research Letters. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes. The study, published in the journal Science Advances, may help resolve what’s known as the faint young sun paradox – a lingering key question in Mars science.
Laser-induced melting occurs nonuniformly in polycrystalline gold thin films—a finding that may be important for precision part micromachining.
New Brunswick, N.J. (Dec. 23, 2019) – The southern Greenland Ice Sheet may experience precipitous melting this century due to a much smaller temperature increase than scientists thought would be required, according to a Rutgers co-authored study. The global sea level…
