We report the first measurements of coupled nitrogen (N) and oxygen (O) isotope fractionation of nitrate by laboratory cultures of denitrifying bacteria. Two seawater strains (Pseudomonas stutzeri,…
Onset of permanent stratification in the subarctic Pacific Ocean
- G. Haug, D. Sigman, R. Tiedemann, T. Pedersen, M. Sarnthein
- Environmental ScienceNature
- 21 October 1999
The surface waters of the modern subarctic Pacific Ocean are isolated from the nutrient-rich waters below by a steep vertical gradient in salinity (halocline), a feature which is a dominant control…
