The salinity:δ18O water relationship in Kongsfjorden, western Spitsbergen
We present the first oxygen isotope measurements from Kongsfjorden in north-west Spitsbergen, and use the isotopic composition and hydrographic data to provide a detailed assessment of the mixing between freshwater and oceanic waters. Temperature, salinity(s) and oxygen isotope profiles are used to...
