Description
Summary:The results, observations, and conclusions are presented of one season's study by the Water Forecasting Unit of the Soil Conversation Service which was undertaken to help in the selection of the best system and equipment for measuring the depth and density of Arctic and sub-Arctic snow. Further objectives of the study were to define specific snow survey problems in the Yukon River basin, and to begin the collection of basic data on the water equivalent of snow in that area. Emphasis is placed on the accuracy of water equivalent determinations, field-accuracy tests of snow samplers, and snow survey field tests in Alaska. In general, it was found that the present Federal snow sampler equipment is as ultilitarian as can be found, but modification of the cutter point is needed to reduce over-measurement error. Aerial snow markers provide a reasonably accurate and inexpensive measurement of snow depth. Small oversnow vehicles can be flown to remote areas and used for transportation to snow courses.
