Airborne radar has detected ≈100 lakes under the Antarctic ice cap, largest of which is Lake Vostok. International planning underway to search in Vostok for microbial life that may have evolved isolation from surface millions years. It thought, however, be hydraulically interconnected. If so, unsterile drilling would contaminate not just one but many them. Here we report measurements temperature vs. depth down 2,345 m at South Pole, within 10 km a subglacial lake seen by airborne profiling....
Abstract. Two ice core boreholes of 143.18 m and 447.73 (bedrock) were drilled during the 2009–2010 austral summer on Bruce Plateau at a location named LARISSA Site Beta (66°02' S, 64°04' W, 1975.5 a.s.l.). Both logged with thermistors shortly after drilling. The shallow borehole was instrumented for 4 months series resistance thermometers satellite uplink. Surface temperature proxy data derived from an inversion profiles are compared to available multi-decadal records weather stations cores...
In order to improve the accuracy of cancer diagnosis, a new convolutional neural network architecture is presented, which provides automatic segmentation and detection kidney tumors on three-dimensional images obtained by computed tomography. The proposed approach based integration three complementary technologies: multilevel processing, residual connections U-Net architectural principles. This ensures efficient processing voluminous medical data. An original system for tomography has been...
Two modifications with variable coefficients of the well-known SEIR model for epidemic development in application to modeling infection curves COVID-19 are considered. The data these models information on number infections each day obtained from Johns Hopkins Coronavirus Resource Center database. In our paper, we propose special methods based Tikhonov regularization models’ identification class piecewise constant coefficients. contrast coefficients, which cannot always accurately describe...
Abstract Seasonal temperature variations occur in the glacier layer about 15–20 m below surface, while at greater depths depends on long-term surface conditions. It is generally accepted that for glaciers without melting 10 depth ( T ) close to mean annual air standard screen level a ), i.e. = . We found this relationship not valid above –17˚C and –55˚C. The goal of our investigation find better transfer function (TTF) between boundary active accumulation areas polar tropical glaciers....
Abstract We use a two-dimensional flowline model to study the flow of Gregoriev ice cap, Tien Shan, central Asia. The takes into account transverse change glacier width, data on measured thickness glacier, surface velocity at front, and mass-balance measurements in 1987 1988. calculated varies from 0 3 ma −1 along flowline. maximum is shifted lowest part towards middle cap for time interval considered (1980–2050) study. derived changes show degradation decrease extent south slope Terskey Ala...
Experimental investigation of shock-wave loading ice (Larson, D. B. J. Glaciol. 1984, 30, 235) indicates a series phase transitions in and gives evidence the important role kinetics plays process dynamic transformations ice. In order to model multiple changes subjected impulsive loading, thermodynamic equations state ices Ih, III, V, VI liquid water are used pressure range 0−2100 MPa temperature 230−350 K. A kinetic is presented that makes it possible describe quantitatively complex picture...
