Inorganic and organic nutrient data from Niskin bottles. Dataset Description: <p>Inorganic and organic nutrient data from Niskin bottles from the KN210-04 cruise. Data include concentration of: phosphate, nitrate+nitrite, silicate, nitrite, ammonium, non-purgeable organic carbon, and total nitrogen.</p> Acquisition Description: <p>Samples for inorganic nutrient analysis were collected in HDPE bottles and frozen (-20ºC) immediately after sample collection. Samples were kept frozen until processing by Joe Jennings at Oregon State University. The analyses for phosphate (PO4), nitrate plus nitrite (NO3_NO2), nitrite (NO2), ammonium (NH4), and silicic acid (silicate) were performed using a hybrid Technicon AutoAnalyzerII and Alpkem RFA300 system following protocols modified from Gordon et al. (see below for reference). The estimated precision for each element was as follows: PO4, ± 0.008 µM; NO3_NO2, ± 0.15 µM; NO2, ± 0.01 µM; silicic acid, ± 0.3 µM.</p>
<p>To obtain the concentration of total organic carbon (TOC) and total nitrogen (TN), a 40 ml aliquot of whole seawater was acidified to pH~3 with concentrated hydrochloric acid (HCl) and stored in combusted glass vials at 4°C until analysis with a Shimadzu TOC-VCSH total organic carbon analyzer coupled to a TNM-1 analyzer. Blanks (MilliQ water) and standard curves with potassium hydrogen phthalate and potassium nitrate were interspersed into the sample runs. The coefficient of variability between replicate injections was &lt;1%. Comparisons to standards provided by Prof. D. Hansell (University of Miami) were made daily.</p>

Ocean Carbon and Biogeochemistry

Ocean Carbon and Biogeochemistry
The Ocean Carbon and Biogeochemistry (OCB) program focuses on the ocean's role as a component of the global Earth system, bringing together research in geochemistry, ocean physics, and ecology that inform on and advance our understanding of ocean biogeochemistry. The overall program goals are to promote, plan, and coordinate collaborative, multidisciplinary research opportunities within the U.S. research community and with international partners. Important OCB-related activities currently include: the Ocean Carbon and Climate Change (OCCC) and the North American Carbon Program (NACP); U.S. contributions to IMBER, SOLAS, CARBOOCEAN; and numerous U.S. single-investigator and medium-size research projects funded by U.S. federal agencies including NASA, NOAA, and NSF.
The scientific mission of OCB is to study the evolving role of the ocean in the global carbon cycle, in the face of environmental variability and change through studies of marine biogeochemical cycles and associated ecosystems.
The overarching OCB science themes include improved understanding and prediction of: 1) oceanic uptake and release of atmospheric CO2 and other greenhouse gases and 2) environmental sensitivities of biogeochemical cycles, marine ecosystems, and interactions between the two.
The OCB Research Priorities (updated January 2012) include: ocean acidification; terrestrial/coastal carbon fluxes and exchanges; climate sensitivities of and change in ecosystem structure and associated impacts on biogeochemical cycles; mesopelagic ecological and biogeochemical interactions; benthic-pelagic feedbacks on biogeochemical cycles; ocean carbon uptake and storage; and expanding low-oxygen conditions in the coastal and open oceans.

Dissolved Organic Matter Composition in the Deep Atlantic Ocean
https://www.bco-dmo.org/project/2204
Dissolved Organic Matter Composition in the Deep Atlantic Ocean
<p>Transformations of dissolved organic matter (DOM) in the deep ocean have profound impacts on the global carbon cycle due to the sequestration of carbon dioxide (CO2) away from the atmosphere. Although research has been conducted on the high molecular weight component of this material, the same cannot be said for low molecular weight DOM because the needed analytical techniques have not been available to determine its composition and reactivity.</p>
<p>In recent years, a research team at Woods Hole Oceanographic Institution has acquired the necessary analytical capability. As such, in this project, they will carry out the first systematic survey of deep ocean DOM in the western Atlantic Ocean to characterize the low molecular weight fraction of DOM in southward flowing North Atlantic Deep Water (NADW), northward flowing Antarctic Bottom Water (AABW), and Antarctic Intermediate Water (AAIW). Using ultrahigh resolution mass spectrometry and multi-stage fragmentation coupled to liquid chromatography, the scientists will determine the spatial variability in the composition of DOM along the flow path of the water masses, as well as assess the source water, transport, and surface processes that contribute to temporal changes in DOM composition. These results will be augmented with structural elucidation and quantitative assays of unique marker compounds for each water mass. Results will provide important insights into the biogeochemical reactions that govern DOM dynamics in the deep ocean.</p>

<p>The data have been examined to identify outliers, and no samples were removed from the dataset. There are values in the inorganic nutrient data which are below zero, and these should be considered as below the detection limit for the instrument.</p>
<p>BCO-DMO Processing Notes:<br />
- Parameter names were modified to conform with BCO-DMO naming conventions.<br />
- lat_start and lon_start were added by joining the data to the event log and matching on the unique event number.<br />
- Replaced 'NaN' with 'nd' to indicate 'no data'.<br />
- Replaced questionable NPOC value for cast 18, niskin 21 with 'nd' per request of PI (change made on 25 July 2016).</p>
