Millennially Averaged Accumulation Rates for the Lake Vostok Region Inferred from Deep Internal Layers
This data set consists of inferred accumulation rates from three radar layers (26, 35 and 41 thousand years old) in the Vostok Subglacial Lake region. Accumulation rates were inferred using Local-Layer Approximation (LLA), which assumes that the strain-rate history of a particle traveling through th...
