Connected Consequences of River Dams
January 12, 2014 | USGS

“In a case study of dams on the upper Missouri River, USGS researchers have demonstrated that an upstream dam is still a major control of river dynamics where the backwater effects of a downstream reservoir begin. In light of this finding, the conventional understanding of how a dam can influence a river may have to be adjusted to account for the fact that effects of river dams can interact with one another.” Quoted from the USGS press release.

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."
