Abstract:
We collected seawater samples during TRANSDRIFT XXI Expedition in August and September 2013 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 (down to ∼310 m depth). The dataset includes nitrate, nitrite, phosphate, silicate and oxygen concentration data , which provide important information on nutrient sources and cycling in the Laptev Sea.
