Rain water chemistry at Calypsobyen, Svalbard
Measurements of pollutants scavenged from air masses over southern Svalbard in summer precipitation are presented. Rainfall was sampled in July and August 2002 at Calypsobyen, Bellsund. Specific conductivity (SpC) and pH were measured and ion con− centrations were determined by ion chromatography. I...
