  2. Radioglaciology - Wikipedia

    en.wikipedia.org/wiki/Radioglaciology

    Radioglaciology is the study of glaciers, ice sheets, ice caps and icy moons using ice penetrating radar.It employs a geophysical method similar to ground-penetrating radar and typically operates at frequencies in the MF, HF, VHF and UHF portions of the radio spectrum.

  3. Ice sheet - Wikipedia

    en.wikipedia.org/wiki/Ice_sheet

    Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.

    No other study has found any evidence to support the hypothesis that ELF exposure is a contributing factor to leukemia in children. [ 40 ] [ 41 ] A 2014 study estimated the cases of childhood leukemia attributable to exposure to ELF magnetic fields in the European Union (EU27), assuming that correlations seen in epidemiological studies were causal.

  5. Timeline of glaciation - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_glaciation

    The hypothesis is still controversial, [5] [6] though is gaining credence among researchers, as evidence in its favour has mounted. [7] A minor series of glaciations occurred from 460 to 430 Ma, and there were extensive glaciations from 350 to 289 Ma. The Late Cenozoic Ice Age has seen extensive ice sheets in Antarctica for the last 34 Ma ...

  6. Ice shelf - Wikipedia

    en.wikipedia.org/wiki/Ice_shelf

    The floating ice shelf is in the left foreground, and the grounding line is visible as an abrupt change in surface slope due to flexure caused by the buoyancy force where the ice reaches flotation. An ice shelf is a large platform of glacial ice floating on the ocean, fed by one or multiple tributary glaciers.

  7. Retreat of glaciers since 1850 - Wikipedia

    en.wikipedia.org/wiki/Retreat_of_glaciers_since_1850

    A study published in 2014 found rapid grounding line retreat in the years 1992–2011. [146] More recently, new satellite imaging data led to calculations of Thwaites Glacier "ice shelf melt rate of 207 m/year in 2014–2017, which is the highest ice shelf melt rate on record in Antarctica." [26]

  8. Ice-sheet model - Wikipedia

    en.wikipedia.org/wiki/Ice-sheet_model

    The fourth IPCC assessment report showed ice-sheet models with projections of rapid dynamical responses in the ice, which led to evidence of significant ice loss. [ 2 ] In 2016, part of the Coupled Model Intercomparison Project Phase 6 (CMIP Phase 6) was the Ice Sheet Model Intercomparison Project , which defined a protocol for all variables ...

  9. West Antarctic Ice Sheet - Wikipedia

    A map of West Antarctica. The total volume of the entire Antarctic ice sheet is estimated at 26.92 million km 3 (6.46 million cu mi), [2] while the WAIS contains about 2.1 million km 3 (530,000 cu mi) in ice that is above the sea level, and ~1 million km 3 (240,000 cu mi) in ice that is below it.
