Dissolved nutrient data from RVIB Nathaniel B Palmer cruise (NBP18-01) in the Amundsen and Ross Seas from December 2017 to March 2018

This dataset provides seawater macronutrient concentrations from the Amundsen and Ross Seas, including from Terra Nova Bay, collected onboard the R/V Nathaniel B. Palmer as part of the Cobalamin and Iron Co-Limitation of Phytoplankton Species (CICLOPS) expedition from December 11, 2017 to March 3, 2018. Samples analyzed for phosphate, nitrite, nitrate + nitrite, silicate and ammonia were collected from full depth profiles via a trace-metal-clean rosette (TMR), filtered with a 0.2 um filter, and stored frozen until analysis via a nutrient autoanalyzer. Sensor hydrography data from each sample depth is also provided.
