Imaggeo on Mondays: Plate it up – a recipe for sea ice errors

Last week, a team of cryospheric scientists published a paper in The Cryosphere that showed how tiny plates of ice can lead to spurious estimates of sea ice thickness. This week, we’re featuring their findings, as well as some spectacular sea ice images in the latest in our Imaggeo on Mondays series… Viewing the poles from above is a stunning sight – a seemingly endless expanse of bril ...[Read More]

The world’s oldest, deepest freshwater lake lies in southeast Siberia: Lake Baikal. Stretching some 600 kilometres across the Russian landscape, Baikal marks what the very early stages of a new ocean – an ancient rift that cleaved the centre of Asia apart throughout the Palaeozoic, Mesozoic and Cenozoic. Today, there are still signs of tectonic activity and the rift continues to diverge 4 mm furth ...[Read More]
