Changes of major ion concentrations in melting snow and terrestrial waters from northern Victoria Land, Antarctica.
Entry ID: Ion_concentr_Victoria_Land

Abstract: Concentrations of major ions (Cl-, NO3-, SO42-, Na+, K+,Mg2+, Ca2+) where
measure in melting snow and water samples from stream and lakes in ice-free
areas throughout northern Victoria Land. Most ions in snow and terrestrial
water are derived from the marine environment and their concentrations are
extremely variable in species and time, especially in water systems without
melting snow and ice. ... View entire text

Quality Sample of melting snowbanks, stream and lake waters were collected in January
and February 2002 from ice-free areas of northern Victoria Land. Temperature,
pH and conductivity were measured on the site using portable meters. Bottles
were brought back to the laboratory of Terra Nova Bay and stored at 20 degrees
C for transport to Italy. In the Siena University laboratories samples were
melted and immediately analyzed. Analysis of Major cations (Ca2+, Mg2+, Na+,
K+ and NH4+) and anions (Cl-, NO3- and SO42-) was carried out by ion
chromatography (IC) using a Dionex DX-120 ion chromatograph.
