A glacier (US: /ˈɡleɪʃər/ or UK: /ˈɡlæsiər, ˈɡleɪsiər/) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.
Fluid property regulator
InactiveUS20080277492A1Low average atmospheric temperatureReduce greenhouse gasFog dispersionMachines/enginesAtmospheric airVolumetric Mass Density
A self-sufficient material property profile regulation method and system, for adjusting fluid property profiles such as in an ocean of multiple property layers, is described. Using this Fluid Property Regulator, the property profiles of a non-enclosed material, including property profiles related to material density, chemical characteristics and space-time position, are affected due to motion of the material relative to a body in the flow stream. The state of other matter with which the initial material then makes direct or indirect contact is also affected. For example, in the case of a liquid such as an ocean current, the temperature, salinity, nutrient content and other properties may be destratified (i.e. layers being combined) as the system lifts large quantities of deep water and combines this material with surface water in the downstream far-field region of the system. The resulting regulation of such ocean water property profiles may then also indirectly affect the properties of the atmosphere above the ocean so that the system can be said to affect planetary properties both oceanic and atmospheric. Rather than merely discharging a pumped material, such as cold water that might quickly re-submerge, the system regulates lasting property profiles. The new Fluid Property Regulator system described in this invention regulates material properties to produce desired outcomes such as increased food and energy production as well as to prevent undesirable outcomes such as hurricanes, elevated planetary temperatures, decreased planetary ice sheet size, raised sea level and glacial freshwater incursions that can halt important major currents.

Methods and apparatus are provided for controlling temperatures in the environments of oil, gas condensate, or gas wells. Methods are provided for reducing the melting of glaciers and ice dams through the deployment of hydrate-forming substances. Active methods involve employing a vapor-compression refrigerator / heat pump cycle in an annulus lying between the relatively hot production string and the relatively cold outer pipe. Passive methods include: deploying cold hydrate-forming fluids into the external ice-laden environment of an oil, gas condensate, or gas well in a permafrost area and allowing those hydrate forming fluids to mix with any melt-water that may be present or that may subsequently form due to the loss of heat from the oil, gas condensate, or gas well. Mixtures of the hydrate forming fluids and the melt-water will set up into a solid having a much higher melting point and a much lower thermal conductivity than those of ice.

ActiveCN103513256AExact horizonElectromagnetic wave reradiationRadio wave reradiation/reflectionRadarMiniaturization
The present invention discloses a method for extracting data layer of a polar-region ice radar, which comprises the following steps: a first step, initializing an algorithm, inputting an image to be processed, and simultaneously setting initial values of an original image recovering coefficient, image layer extracting coefficient, regularizing coefficient and layer extracting regularizing factor; a second step, determining whether an iteration termination condition is satisfied, if yes, outputting original image recovery and image layer extracting result, and if no, entering an iteration process of a third step; and the third step, repeatedly performing original image recovering and image layer extracting, processing by means of a gradient frame in original image recovering, and processing by means of a total variation miniaturization gradient frame in image layer extracting; and at the final period of the iteration process, updating the value of the layer extracting regularizing factor by means of a conjugate gradient algorithm; wherein every the step is iterated once, returning to the second step for determination is performed until the iteration termination condition is satisfied. Accurate layer of a glacier can be obtained by means of the method of the invention.
