Entrapment of long-distance transported pollen grains by various moss species in coastal Victoria Land, Antarctica

Listed in NASA Earthdata CMR

In northern Victoria Land (continental Antarctica, between 72 and 76 degrees S, 162 and 169 degrees E), 18 moss samples have been collected and analyzed for the presence of pollen.

Description

In turfs and cushions of 8 different moss species, at least 27 pollen taxa could be identified. The Pinus-type pollen and those of grasses were very common.

More than 60% of the total grains were damaged or could not be identified. There is evidence that the Antarctic continent could act as a sink for wind-transported pollen from sub-Antarctic island or from plants (native or cultivate) in South America, Australia, New Zeland and South Africa. However, the pollen concentration in air (1 pollen grain/100 m3) and its entrapment rate on moss (about 0.12 grain/cm2/year) result in a very low pollen density in these plants.
