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

Abstract:

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.

Methods & Sampling

Hydrographic data was collected during the RVIB Nathaniel B. Palmer cruise (NBP1801) from December 31st, 2017 to March 3rd, 2018. Samples were collected by trace metal rosette (TMR) using the Saito laboratory 8L X-Niskin bottles. Bottles were brought into a clean van, pressurized with high-purity nitrogen gas and filtered through 0.2 micron 142mm Supor membrane filters. Nutrient samples were filled in acid-washed 60mL HDPE bottles and frozen until analysis.

Nutrient analyses were conducted by Joe Jennings at Oregon State University using a nutrient autoanalyzer following the methods of Noble et al. (2012). Technicon AutoAnalyzer II components were used to measure phosphate and ammonium. Alpkem rapid flow analyzer (RFA) 300 components were used to measure silicic acid, nitrate+nitrite, and nitrite.

For quality control (QC) notes, please see the document "Quality Control notes for NBP1801 nutrients" in the Supplemental Files section.

NOTE: The PAR sensor was not present on the first leg of the cruise, so PAR values were not measured until Station 35.

Instruments

Alpkem RFA300

Supplied Name: Alpkem rapid flow analyzer (RFA 300)

Supplied Description:

Alpkem rapid flow analyzer (RFA) 300 components were used to measure silicic acid, nitrate+nitrite, and nitrite.

Instrument Type

Generic Name: Alpkem RFA300

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0414/

Generic Description:

A rapid flow analyser (RFA) that may be used to measure nutrient concentrations in seawater. It is an air-segmented, continuous flow instrument comprising a sampler, a peristaltic pump which simultaneously pumps samples, reagents and air bubbles through the system, analytical cartridge, heating bath, colorimeter, data station, and printer. The RFA-300 was a precursor to the smaller Alpkem RFA/2 (also RFA II or RFA-2).

Supplied Description:

Trace metal rosette had hydrographic sensors including Biospherical Instruments QSP-2350 PAR sensor

Instrument Type

Generic Name: Biospherical PAR sensor

Generic Description:

An irradiance sensor designed to measure Photosynthetically Active Radiation (PAR), manufactured by Biospherical Instruments Inc.

CTD Sea-Bird SBE 911plus

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics

Sea-Bird SBE-4 Conductivity Sensor

Supplied Name: Sea-Bird 4C conductivity sensor

Supplied Description:

Instrument Type

Generic Name: Sea-Bird SBE-4 Conductivity Sensor

Acronym: SBE-4 Conductivity

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0417/

The Sea-Bird SBE-4 conductivity sensor is a modular, self-contained instrument that measures conductivity from 0 to 7 Siemens/meter. The sensors (Version 2; S/N 2000 and higher) have electrically isolated power circuits and optically coupled outputs to eliminate any possibility of noise and corrosion caused by ground loops. The sensing element is a cylindrical, flow-through, borosilicate glass cell with three internal platinum electrodes. Because the outer electrodes are connected together, electric fields are confined inside the cell, making the measured resistance (and instrument calibration) independent of calibration bath size or proximity to protective cages or other objects.
