摘要：

Three new samplers were developed for detailed analysis of the three-dimensional characteristics of frazil ice deposits beneath an ice cover. These samplers obtain in-situ bulk, hollow core and flat plate samples of the deposits through 200-mm-diameter access holes. The samples provide information on a deposit's internal structure, stratigraphy and sedimentology, geometry and physical properties, and lateral and vertical variabilities of each. When used as part of a comprehensive field program, the data provide information required for interpreting mechanisms of frazil transport and deposition, and for analyzing the dynamic interaction of frazil deposits with winter river processes. © 1990 Elsevier Science Publishers B.V.
