High-resolution stable water isotope composition of firn core OH-12 from Plateau Laclavere, northern Antarctic Peninsula
The firn core OH-12 was retrieved from Plateau Laclavere, a small ice cap on the northernmost end of the Antarctic Peninsula at about 1090 m above sea level in January 2016. The core was drilled down to 19.93 m depth. Subsamples for stable water isotope analysis were obtained from the core at 5 cm r...
