Nutrient and oxygen concentrations, alkalinity and pH measured on water bottle samples collected during cruise Transdrift-XXII (VB14) in 2014, Laptev Sea

We collected seawater samples during TRANSDRIFT XXII Expedition in September and October 2014 along with CTD (conductivity, temperature, depth) profiles with a SBE 32 rosette water sampler equipped with 12 Niskin bottles (2.5 L) under ice-free conditions onboard the Russian research vessel RV Viktor Buynitskiy on the entire Laptev Sea shelf and above the shelf slope. The dataset includes nitrate, nitrite, ammonia, total nitrogen, phosphate, silicate and oxygen concentration data, as well as pH and total alkalinity, which provide important information on the geochemical state of the Laptev Sea
