Warm climate isotopic simulations: what do we learn about interglacial signals in Greenland ice cores?
Read more of: Warm climate isotopic simulations: what do we learn about interglacial signals in Greenland ice cores?Measurements of Last Interglacial stable water isotopes in ice cores show that central Greenland d18O increased by at least 3& compared to present day. Attempting to quantify the Greenland interglacial […]

Rapid long-distance migration in Norwegian Lesser Black-backed Gulls Larus fuscus fuscus along their eastern flyway
Read more of: Rapid long-distance migration in Norwegian Lesser Black-backed Gulls Larus fuscus fuscus along their eastern flywayWe studied the long-distance migration of Lesser Black-backed Gulls Larus fuscus fuscus breeding in northern Norway along their eastern flyway using geolocators in 2009 and 2010. The majority of birds […]

Wintertime water mass modification near an Antarctic ice front
Read more of: Wintertime water mass modification near an Antarctic ice frontUnder ice measurements by seals carrying a miniaturized conductivity–temperature–depth (CTD) instrument fill an important gap in existing observations. Here the authors present data from an instrumented Weddell seal that spent […]

Biological production in the Bellingshausen Sea from oxygen-to-argon ratios and oxygen triple isotopes
Read more of: Biological production in the Bellingshausen Sea from oxygen-to-argon ratios and oxygen triple isotopesWe present estimates of mixed-layer net community oxygen production (N) and gross oxygen production (G) of the Bellingshausen Sea in March and April 2007. N was derived from oxygen-to-argon (O2/Ar) […]
