Physical oceanography, nutrients, and δ¹⁸O measured on water bottle samples during POLARSTERN cruise ARK-XXII/2 ...

Extremely low summer sea-ice coverage in the Arctic Ocean in 2007 allowed extensive sampling and a wide quasi-synoptic hydrographic and d18O dataset could be collected in the Eurasian Basin and the Makarov Basin up to the Alpha Ridge and the East Siberian continental margin. With the aim of determin...
