Hidrología y variación topográfica de un riachuelo subantártico en la ensenada MacKellar, Isla Rey Jorge, Antártida

Hidrología y variación topográfica de un riachuelo subantártico en la ensenada MacKellar, Isla Rey Jorge, Antártida

The purpose of this study is to present preliminary results of the hydrologic and topographic monitoring of a small stream at the King George Island, Antarctica. Two methods were used in order to measure stream discharge: an area-velocity method using a flow meter and a Parshall flume. Also a topogr...
