| 释义 | meltwater noun[ U ] geography specializeduk /ˈmeltˌwɔːtər/ us /ˈmeltˌwɑː.t̬ɚ/ water made from melted snow or ice冰雪融成的水 Examples of meltwatermeltwater It was postulated that the movement of water through hydrocarbon-contaminated sediments would result in the dispersal of hydrocarbon-contaminated meltwater downhill towards the sea. The mobilisation of hydrocarbons combined with meltwater inflow is obviously limited to the brief part of the summer in which liquid water occurs. During monitoring, emphasis was given to the interaction of contaminated sites with periglacial, meltwater and aeolian processes. This wide plain consists of an area of grey sandy outwash cut with deep gullies created by glacial meltwater. Thermoerosion takes place due to energy transported to the lowermost part of the frozen material by means of meltwater. The figure shows many successful matches on the lower half of the glacier, particularly on the eastern side, all derived from meltwater channels. Once ice thaws, continued radiation effects can cause mixing of the fuel with meltwater. They noted a strongly bisected coastline, with inlets reaching towards the ice cap, and numerous meltwater lakes, often without apparent external discharge. However, we suspect that such nutrients are deposited from meltwater into impact-generated cavities, which would encourage endolithic heterotrophic bacteria to inhabit them. The interaction of contaminated sites with meltwater/groundwater and aeolian processes did not significantly change the hydrocarbon distribution at the former base site during the monitoring period (1992- 96). The semi-automated method shows that reliable and consistent velocity vectors can be extracted from meltwater channels, and that these retain their identity over at least two years. Nutrient rich lakes are found near the coast; sterile lakes are located further inland and are fed by meltwater and local precipitation. It was also possible to track the motion of fine-scale features in the surface geometry such as meltwater channels, and hence to determine the glacier's surface velocity, in some areas. As the ice continued to retreat, a series of east-west channels were cut by the easterly flowing glacial meltwater.
