Leningradskiy Ice Cap Snowcover Vanishes in 2020 More Thinning, Svernaya Zemlya

Leningradskiy Ice Cap  north to south strip in 2000 and 2020 Landsat images illustrating thinning leading to separation of parts of the ice cap at Point 1 and 4 and expansion of bedrock leading to merging bedrock regions at Point 1 and 2. R=snow/firnpack saturated with meltwater and consequent potential refreezing. S=superimposed ice development from surface refreezing. Leningradskiy Ice Cap is oriented east to west across Bolshevik Island in the …

Kronotsky Peninsula, Kamchatka Glacier Fragmentation/Retreat

The Kronotsky Peninsula is on the east coast of Kamchatka and has an small concentration of alpine glaciers.  A recent paper by Lynch et al (2016) indicates a significant recession during the start of the 21st century in Kamchatka.  They note a 24% loss in area, leading to fragmentation and an increase in the number of ice masses that could be considered glaciers.  Lynch et al (2016)  further note that the …
