Rivers Play Role in Arctic Sea Ice Melt
March 13, 2014 | NASA
"The heat from warm river waters draining into the Arctic Ocean is contributing to the melting of Arctic sea ice each summer. [...] NASA used satellite data to measure the surface temperature of the waters discharging from a Canadian river into the icy Beaufort Sea during the summer of 2012. They observed a sudden influx of warm river waters into the sea that rapidly warmed the surface layers of the ocean, enhancing the melting of sea ice."
