Spectral magnitude data for 0.0008 ppm bands from aerosol water soluble organic matter 1H NMR spectra. Dataset Description: <p>The sampling details and identities of each of the samples is provided in addtion to the NMR data. This includeds: starting and ending locations (latitudes and longitudes) and times (Greenwich mean time) as well as the sampling rates (m<sup>3</sup> min<sup>-1</sup>) and calculated sample volumes (m<sup>3</sup>) for each of the aerosol samples. The run times (measured in hours) and sample volumes account for periods when the sampler was stopped due to potential contamination from the ship’s stack. The NMR data are reported as spectral intensity units, which are non-quantitative, and chemical shift - at parts per million difference from a reference signal, the hydrogens in tetramethylsilane. Spectral images are also provided as JPEG files. These images show&nbsp;the NMR spectra from which the numerical data are derived.</p> Methods and Sampling: <p>The analytical and data processing methodology have been described in Wozniak et al. (2013, 2015). The full citations for these references are below. A summary of the methods is quoted here:<br />
Aerosol WSOM was minimally diluted with D<sub>2</sub>O and analyzed on a Bruker Biospin Avance III 400 MHz NMR with a broadband inverse solution state probe at ODU’s College of Sciences Major Instrumentation Cluster facility using a water suppression technique described previously (e.g., Wozniak et al., 2013). WSOM samples were diluted to a final composition of 9:1 sample:D<sub>2</sub>O and 500 µL of this solution was added to 5 mm glass NMR tubes and analyzed without further manipulation. Spectra were acquired using a 2 s recycle delay, a 119 ms acquisition time, a time domain of 16 k, and co-adding 8000 scans. The summed free induction decay signal was exponentially multiplied and zero-filled once. The spectra were processed with a line broadening of 3 Hz.</p>
<p>* During data processing for publications from this work (Wozniak et al., 2013, 2015), spectral chemical shifts corresponding to potential solvent interferences from hydrogens in residual water (region excluded: 4.6 ppm to 4.8 ppm), methanol (region excluded: 3.28 ppm to 3.46 ppm), and tetramethylsilane (region excluded: &lt;0.095 ppm) were set to 0. The data archived here do not have these sections set to 0.</p>
<p>** The data for samples 7587, 8044, and 8045 have been flagged as bad and are not included here. Multiple attempts were made to rerun these samples, but adequate spectra were not obtained.</p>

U.S. GEOTRACES
GEOTRACES is a SCOR sponsored program; and funding for program infrastructure development is provided by the U.S. National Science Foundation.
GEOTRACES gained momentum following a special symposium, S02: Biogeochemical cycling of trace elements and isotopes in the ocean and applications to constrain contemporary marine processes (GEOSECS II), at a 2003 Goldschmidt meeting convened in Japan. The GEOSECS II acronym referred to the Geochemical Ocean Section Studies To determine full water column distributions of selected trace elements and isotopes, including their concentration, chemical speciation, and physical form, along a sufficient number of sections in each ocean basin to establish the principal relationships between these distributions and with more traditional hydrographic parameters;
* To evaluate the sources, sinks, and internal cycling of these species and thereby characterize more completely the physical, chemical and biological processes regulating their distributions, and the sensitivity of these processes to global change; and
* To understand the processes that control the concentrations of geochemical species used for proxies of the past environment, both in the water column and in the substrates that reflect the water column.
GEOTRACES will be global in scope, consisting of ocean sections complemented by regional process studies. Sections and process studies will combine fieldwork, laboratory experiments and modelling. Beyond realizing the scientific objectives identified above, a natural outcome of this work will be to build a community of marine scientists who understand the processes regulating trace element cycles sufficiently well to exploit this knowledge reliably in future interdisciplinary studies.

U.S. GEOTRACES North Atlantic Transect (GA03)
https://www.geotraces.org/
U.S. GEOTRACES North Atlantic Transect (GA03)
<p><em>Much of this text appeared in an article published in OCB News, October 2008, by the OCB Project Office.</em></p>
<p>The first U.S. GEOTRACES Atlantic Section will be specifically centered around a sampling cruise to be carried out in the North Atlantic in 2010. Ed Boyle (MIT) and Bill Jenkins (WHOI) organized a three-day planning workshop that was held September 22-24, 2008 at the Woods Hole Oceanographic Institution. The main goal of the workshop, sponsored by the National Science Foundation and the U.S. GEOTRACES Scientific Steering Committee, was to design the implementation plan for the first U.S. GEOTRACES Atlantic Section. The primary cruise design motivation was to improve knowledge of the sources, sinks and internal cycling of Trace Elements and their Isotopes (TEIs) by studying their distributions along a section in the North Atlantic (Figure 1). The North Atlantic has the full suite of processes that affect TEIs, including strong meridional advection, boundary scavenging and source effects, aeolian deposition, and the salty Mediterranean Outflow. The North Atlantic is particularly important as it lies at the "origin" of the global Meridional Overturning Circulation.</p>
<p>It is well understood that many trace metals play important roles in biogeochemical processes and the carbon cycle, yet very little is known about their large-scale distributions and the regional scale processes that affect them. Recent advances in sampling and analytical techniques, along with advances in our understanding of their roles in enzymatic and catalytic processes in the open ocean provide a natural opportunity to make substantial advances in our understanding of these important elements. Moreover, we are motivated by the prospect of global change and the need to understand the present and future workings of the ocean's biogeochemistry. The GEOTRACES strategy is to measure a broad suite of TEIs to constrain the critical biogeochemical processes that influence their distributions. In addition to these "exotic" substances, more traditional properties, including macronutrients (at micromolar and nanomolar levels), CTD, bio-optical parameters, and carbon system characteristics will be measured. The cruise starts at Line W, a repeat hydrographic section southeast of Cape Cod, extends to Bermuda and subsequently through the North Atlantic oligotrophic subtropical gyre, then transects into the African coast in the northern limb of the coastal upwelling region. From there, the cruise goes northward into the Mediterranean outflow. The station locations shown on the map are for the "fulldepth TEI" stations, and constitute approximately half of the stations to be ultimately occupied.</p>

Role of Organic Matter in Determining the Solubility of Atmospherically-Delivered Iron
http://wozniakresearch.com/geotraces/
Role of Organic Matter in Determining the Solubility of Atmospherically-Delivered Iron
<p><em>Description from NSF award abstract:</em><br />
The atmospheric delivery of soluble Fe to the ocean is an important process contributing to oceanic primary production and the drawdown of atmospheric CO2. Combustion influenced air masses carry highly soluble Fe, but the reasons for this increased solubility remain unclear despite the importance to global carbon cycling. Acidic organic matter (OM) components (e.g., -COOH groups) can complex with trace metals, yet no study to date has investigated the comprehensive molecular characteristics of aerosol OM for their role as a determinant of Fe solubility.</p>
<p>In this project, researchers at Old Dominion University will study the relationship between the molecular characteristics of marine aerosol water soluble OM (WSOM) and Fe solubility. Marine particulate aerosols collected during GEOTRACES cruises will be examined to identify WSOM characteristics that may play a role in delivering soluble and bioavailable Fe to the N. Atlantic Ocean. Aerosol WSOM will be characterized using advanced molecular and chemometric techniques to test whether:<br />
(1) continental combustion-influenced aerosol samples show molecular characteristics unique from those of continental dust influenced samples, having characteristics consistent with higher contributions from OM with acidic functional group;<br />
(2) aerosol WSOM examined along a gradient of Fe solubility show concurrent changes in the relative magnitude of highly oxygenated compounds and contributions from acidic functional groups; and<br />
(3) 2D HMBC NMR reveal unique components in composite continental combustion influenced samples relative to marine and dust-influenced samples, and these unique components include OM with carboxyl functional groups that can bind Fe.</p>
<p>This project will be the first of its kind to extensively examine WSOM molecular characteristics and Fe solubility on concurrently collected aerosol samples. The results will be useful for understanding Fe distributions and biogeochemical cycling in the ocean. A potentially transformative aspect of this proposal will be the identification of aerosol WSOM molecular components unique to combustion influenced air masses that have the potential to facilitate aerosol Fe solubility.</p>
<p>The findings of this project are expected to be highly relevant to oceanic and global biogeochemical cycling of OM and many trace metals that form organic complexes. Combustion-influenced OM associations may help explain patterns in the global oceanic distribution of other trace metals and provide key insights into oceanic processes (e.g., primary production, biological pump).</p>
