Estimates of lichen growth rates in the maritime Antarctic

Using growth rates estimated from lichens growing on introduced substrata on Signy Island, South Orkney Islands (lat. 61 °S., long. 45 °W.), the two most recent moraines of a glacier on this island have been tentatively dated as being deposited around 1880 and 1837. The growth rate of Rhizocarpon ge...

Description
Summary:Using growth rates estimated from lichens growing on introduced substrata on Signy Island, South Orkney Islands (lat. 61 °S., long. 45 °W.), the two most recent moraines of a glacier on this island have been tentatively dated as being deposited around 1880 and 1837. The growth rate of Rhizocarpon geographicum is estimated on Signy Island to be an increase of about 16 mm in diameter per century
