Abstract:SummarySpatial and temporal variability of a sea-salt aerosol (Na + ) concentration was investigated in snow-firn cores and snow pits taken at four sites of the Indian Ocean sector of the East Antarctica (along a profile between stations Progress and Vostok: PV-10, NVFL-1, SW-42, and the Vostok point). In long annually resolved Na + records, we had revealed the following periodicities: 17 to 95-year (Vostok) and 29 to 52-year (NVFL-1), while the shorter records are characterized by 8-year periodicity. The Na +… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
