Limited Migration of Soluble Ionic Species in a Siple Dome, Antarctica, Ice Core
High-resolution (>10 samples a -1) glaciochemical analyses covering the last 110 years from a Siple Dome, Antarctica, ice core reveal limited migration of certain soluble ionic species (methane sulfonic acid, NO3 and Mg2+). Th e observed chemical migration m ay be due in part to seasonal alternat...
