Ross Sea Productivity Dataset Description: Methods and Sampling: <p><strong>Methodology:</strong><br />
The methods used in all were based on simulated in situ incubations and productivity measured by uptake of radiocarbon. Methodology for all is largely the same, with some slight variations in the irradiance levels for incubation. Incubations lasted for 24 h and 7 depths per station were measured. A total of 449 stations are compiled that were sampled from 1983 to 2006. Details of the methodology are described in Smith et al. (2000). Any inconsistencies found within the 449 stations should be reported to the PI for correction. Additional details on data compilation are in the attached <a href="https://datadocs.bco-dmo.org/docs/305/Ross_Productivity/data_docs/Ross_Sea_Productivity_README_v2.pdf" target="_blank">README file</a> (PDF).</p>
<p><strong>Sampling and Analytical Procedures:</strong><br />
Samples were obtained from CTD casts with attached Niskins on the rosette. Irradiance was determined largely using an in situ PAR sensor, but earlier cruises also used a Secchi disk. Samples had ca. 100 µCi ¹⁴C-bicarbonate added and placed in on-deck incubators flushed with flowing seawater. Most incubations lasted 24 h after which samples were filtered onto 25 mm GFF filters, rinsed with 5 mL 0.01N HCL in filtered seawater, placed in scintillation vials, and had ca. 7 mL scintillation cocktail added. Total activity added to each bottle was assessed by counting an unfiltered sample (100 µL) directly in LS cocktail. All samples were counted using a liquid scintillation counter after 24 h in darkness, and DPMs converted to absolute carbon units using known equations (Smith et al., 1977).</p>
<p>Chlorophyll was determined fluorometrically using standard JGOFS procedures. Samples were collected from known depths into amber polycarbonate bottles, known volumes filtered through 25 mm GFF filters under low vacuum, extracted for 24 h in 90% acetone in dark, cold conditions, and the fluorescence read before and after acidification.</p>
<p>Mixed layers were determined from the vertical profiles of density (sigma-t) determined from CTD profiles. A change of 0.01 kg m⁻³ from a stable surface layer reading was defined as the base of the mixed layer (Smith et al., 2013).</p>
<p>Integrated primary productivity and chlorophyll concentrations were determined using trapezoidal integrations through the 0.1 and 1.0% isolumes, respectively. Photosynthetically active radiation (PAR) were collected using a BioSpherical Sensor Model QSP-240 placed as close to the incubators as possible. All data were integrated from 1-minute values over the period of incubation. The integrated data by station are provided in the attached Supplemental File "<a href="https://datadocs.bco-dmo.org/data/305/Ross_Productivity/863815/2/data/integrated_water_column_station_data_v2.csv" target="_blank">Integrated Water Column Station Data</a>" (.csv file).</p>

U.S. Joint Global Ocean Flux Study
http://usjgofs.whoi.edu/
U.S. Joint Global Ocean Flux Study
The United States Joint Global Ocean Flux Study was a national component of international JGOFS and an integral part of global climate change research.
The U.S. launched the Joint Global Ocean Flux Study (JGOFS) in the late 1980s to study the ocean carbon cycle. An ambitious goal was set to understand the controls on the concentrations and fluxes of carbon and associated nutrients in the ocean. A new field of ocean biogeochemistry emerged with an emphasis on quality measurements of carbon system parameters and interdisciplinary field studies of the biological, chemical and physical process which control the ocean carbon cycle. As we studied ocean biogeochemistry, we learned that our simple views of carbon uptake and transport were severely limited, and a new "wave" of ocean science was born. U.S. JGOFS has been supported primarily by the U.S. National Science Foundation in collaboration with the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, the Department of Energy and the Office of Naval Research. U.S. JGOFS, ended in 2005 with the conclusion of the Synthesis and Modeling Project (SMP).

Instrument Name: CTD Sea-Bird SBE 911plus Instrument Short Name:CTD SBE 911plus Instrument 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 Community Standard Description: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

PI Supplied Instrument Name: various PI Supplied Instrument Description:Various LSCs were used, depending on the unit on each ship, but all samples were processed at sea. Instrument Name: Liquid Scintillation Counter Instrument Short Name:LSC Instrument Description: Liquid scintillation counting is an analytical technique which is defined by the incorporation of the radiolabeled analyte into uniform distribution with a liquid chemical medium capable of converting the kinetic energy of nuclear emissions into light energy. Although the liquid scintillation counter is a sophisticated laboratory counting system used to quantify the activity of particulate emitting (ß and a) radioactive samples, it can also detect the auger electrons emitted from 51Cr and 125I samples.
Liquid scintillation counters are instruments assaying alpha and beta radiation by quantitative detection of visible light produced by the passage of rays or particles through a suitable scintillant incorporated into the sample.

Instrument Name: Niskin bottle Instrument Short Name:Niskin bottle Instrument Description: A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc. Community Standard Description: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/
