This dataset contains water column samples that were collected at designated bottom water depths during the cruises, primarily utilizing a CTD/rosette bottle system, although sometimes with a water pumping system (COMIDA CAB 2009 and 2010). Cruises included in this synthesis data set are outlined in the Pacific Marine Arctic Regional Synthesis (PacMARS) Final Report, Methods section to be posted on the PacMARS website (http://pacmars.cbl.umces.edu/). Each sample depth has associated latitude, longitude, water depth, and four nutrient collections: silica, nitrite/nitrate, phosphate and ammonia. Note that many of these data are also listed in full hydrographic files. Links to these referenced files can be found in the README documentation.
