Concentration of nitrate, nitrite, and phosphate in the water column at four different stations in the Arabian Sea off Pakistan during the METEOR cruise M74/2 in 2007

Sampling was conducted during the R/V Meteor cruise M74/2, on 7th to 28th October 2007, in the Arabian Sea over the Pakistan shelf. Four stations ranging from 360 to 1430 m were selected for detailed sampling and sediment incubations. Pore water samples for nitrate and nitrite were kept frozen until measurement with a chemiluminescence NOx analyzer (Thermo Environmental Instruments, Inc; Braman and Hendrix, 2002) in a shore based laboratory.
