    Arctic, Antarctic, and Alpine Research publishes research and book reviews on any scientific or cultural aspect of Arctic, Antarctic, and alpine environments. The water excluded during river ice formation, which is slightly lighter, would thus contain an apparent extra 15% RW and 19% negative SIM. In the estuary, where the ice comprises m of river ice, the effect would be an overestimate of the fraction of river water in the water column by m and an overestimate of ice growth by by:

River-ice conditions in the Nelson River drainage system by Donald Kenneth MacKay Download PDF EPUB FB2

Hydrological and meteorological observations related to ice conditions on rivers in the Nelson drainage system are compared statistically to determine the measure of agreement between them. The results show a high degree of positive correlation.

The areal variability of ice formation, ice disintegration, mean length of the ice-free season, and the standard deviation of first-ice and last-ice Author: Donald Kenning MacKay.

The Nelson River is a river of north-central North America, in the Canadian province of river drains Lake Winnipeg and runs kilometres ( mi) before it ends in Hudson full length (including the Saskatchewan River and Bow River) is 2, kilometres (1, mi), it has mean discharge of 2, cubic metres per second (84, cu ft/s), and has a drainage basin of Country: Canada.

Glacial Lake Glendive was a glacial lake on the lower Yellowstone formed in the valley of Yellowstone, during the late Pleistocene epoch south of the Keewatin Ice the ice sheet retreated northward, the lake drained into the modern Missouri River.

Monday afternoon, 2/17 – The ice is in very good shape as is the skiing. Basically, we are in full winter conditions right now and hopefully, they will last 3 or 4 more weeks The skiing in the woods is great. Chapel Pond Region – The Canyon climbs are in and very good right now as is Chouinard’s and Crystal Ice Tower.

Power Play is. Samples of river flow, precipitation, snow cover, and permafrost ground ice were collected over the watersheds to determine isotopic composition of potential sources of water in a river flow over.

Its temperature was degrees from the top to the bottom (red line) as a result of the turbulent mixing of the river.

Lake George (NY) shows a typical deep lake temperature profile (blue curve). Warm conditions will melt the ice in the usual fashion and warm rain might allow the water temperature of the river to rise a little.

In fact, this is not the case - the variability of large rivers indicates that other important factors are involved. River Variability and Complexity presents an interesting approach to the understanding of river variability.

It provides examples of river variability and explains the reasons for them, including fluvial response to human by: river ice processes in a profound wa~: a dam and a nuclear power plant.

Heat from GW upwelling can degrade river ice from below. Field observations show that GW heat flux exceeds atmospheric heat losses and that dangerously thin ice conditions can be maintained for extended periods despite very cold wintertime air temperatures ().In recent decades, there have been several reports that thin ice and open water may be more prevalent on interior Alaskan rivers in Cited by: 4.

This book carefully brings together a range of studies that have been previously inaccessible providing a rare and comprehensive analysis of the effects of a big dam on a river, a river that itself represents an example of the kind of system that is likely to receive considerable attention in the future from dam engineers and environmentalists.

The frequency and thickness of ice layers in the snow pack on land in many areas of the Arctic are increasing as warmer winters lead to unseasonal snow melt events.

Sea, lake, and river ice cover duration is also declining (Meier et al.,Prowse et al., ).
