Arctic Ocean was once a tub of fresh water covered with a half-mile of ice

The Arctic Ocean was once a pool of fresh water capped with an ice shelf half as thick as the Grand Canyon is deep. If that's hard to envision, don't despair. Scientists were surprised at the discovery, published Wednesday (Feb. 3) in the journal Nature, as well. The trick to envisioning this odd arrangement is to think about the relationship between ice sheets and the ocean. When ice sheets melt, they dump water into the ocean, raising the sea level. But when ice sheets grow, as they have during Earth's glacial periods, sea level drops.

Conservation authority, farmer discuss soil and water health

Maitland Conservation (MC), formerly Maitland Valley Conservation Authority (MCVA), has been monitoring two agricultural sub-watersheds to address water quality concerns and the effects of farming practices on local water. Ben Van Dieten, Agricultural Stewardship Technician, and Chris Van Esbroeck, Stewardship Services Coordinator of MC, presented their findings to date on these projects, in terms of how and when sediment and nutrients leave the landscape, and the practices they promote to reduce these losses.

Future of Water | Adding capacity and resilience to Canadian dam

As the upgrade of Glenmore Dam draws to a close, NCEexplores how the Canadian structure has evolved to help reduce flood risk, while increasing its water supply capacity. Canada’s Glenmore Reservoir has become an important landmark in the city of Calgary, providing clean water, flood mitigation and a recreational setting for locals. The 3.8km2 reservoir is formed by a concrete dam, which has been the focus of a C$81M (£46M) improvement project. Approximately 320m long, Glenmore Dam is located on the Elbow River in south west Calgary. The structure was originally built in 1933 to supply drinking water and enable the city to cater for future population growth.
