Vertical properties of nutrients and oxygen under temperature-salinity structure of the Bering Basin in July 1999
The China R/V Xuelong went on the first Arctic scientific cruise, and we obtained 271 hydro-chemical samples from 22 deep-sea stations in the Bering Basin in late July, 1999. Here we describe vertical properties of silicate [Si], dissolved inorganic nitrogen [DIN] or [N] (nitrate plus ammonium + nit...

The China R/V Xuelong went on the first Arctic scientific cruise, and we obtained 271 hydro-chemical samples from 22 deep-sea stations in the Bering Basin in late July, 1999.
