Water column nutrient observations, Apr-Sept 2001-02, continental margin to the west of the Antarctic Peninsula, GLOBEC.
Listed in NASA Earthdata CMR
Water column sampling for nutrient chemistries (NO2+NO3, NO2, Si(OH)4, PO4 and NH4) were collected using a CTD niskin rosette sampler during 4 cruises to the Antarctic, April-September 2001 and 2002.
Description
The general survey area includes: the continental margin to the west of the Antarctic Peninsula extending from the northern tip of Adelaide Island to the southern portion of Alexander Island, Marguerite Bay, and seaward to depths of 3000 meters.
Analytical methods used for silica, phosphate, nitrite, and nitrate follow the recommendations of Gordon et al. (1993) for the WOCE WHP project. Ammonia followed modified methods reported by Grosshoff (1976). An upgraded five-channel Technicon Autoanalyzer II system was used for sample analysis.
