attribute	NC_GLOBAL	acquisition_description	String	Methods for the Collection and Measurement of Dissolved Organic Carbon (DOC): Seawater samples for analysis of dissolved organic carbon (DOC) and chromophoric dissolved organic matter (CDOM) absorption are filtered under a gentle vacuum (<5 in Hg) through pre-combusted (6 hours at 450\u00b0C) Whatman GF/F glass fiber filters and collected directly into pre-cleaned and pre- combusted sample glass bottles and vials. Duplicate samples at the surface and single samples at depth are collected for DOC analysis and stored frozen at -20\u00b0C. Samples are measured by high temperature combustion oxidation (HTCO) on a Shimadzu TOC-L carbon analyzer. Mean of replicate runs for individual samples must maintain a standard deviation <2% for a minimum of 3 of 7 injections (Benner and Strom 1993; Sharp et al. 2002; Mannino et al. 2008). Accuracy of analyses is monitored by running DOC consensus reference material standards (CRM; Hansell Laboratory, University of Miami RSMAS); CRM measurements must maintain an analytical error to within \u00b15% of the consensus values. Standard curves of the manufacturer-recommended carbon standard, potassium hydrogen phthalate (KHP), ranging from ~500 to 4000 \u03bcg C L-1 and from ~500 to 2000 \u03bcg C L-1 are conducted daily. KHP check standards are interspersed between every 6 samples for each sample batch to verify the consistency of the standard curve throughout each sample batch analyzed. To minimize salt accumulation in the instrument flow path, Milli-Q water blanks are inserted between every 3 samples for each batch of samples. Injection volumes for seawater samples, standards and blanks are typically 120\u03bcL.

attribute	NC_GLOBAL	projects_0_description	String	Much of this text appeared in an article published in OCB News, October 2008, by the OCB Project Office. 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. 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. Figure 1. The proposed 2010 Atlantic GEOTRACES cruise track plotted on dissolved oxygen at 400 m depth. Data from the World Ocean Atlas (Levitus et al., 2005) were plotted using Ocean Data View (courtesy Reiner Schlitzer). [click on the image to view a larger version] Hydrography, CTD and nutrient measurements will be supported by the Ocean Data Facility (J. Swift) at Scripps Institution of Oceanography and funded through NSF Facilities. They will be providing an additional CTD rosette system along with nephelometer and LADCP. A trace metal clean Go-Flo Rosette and winch will be provided by the group at Old Dominion University (G. Cutter) along with a towed underway pumping system. The North Atlantic Transect cruise began in 2010 with KN199 leg 4 (station sampling) and leg 5 (underway sampling only) (Figure 2). KN199-04 Cruise Report (PDF) Figure 2. The red line shows the cruise track for the first leg of the US Geotraces North Atlantic Transect on the R/V Knorr in October 2010.  The rest of the stations (beginning with 13) will be completed in October-December 2011 on the R/V Knorr (courtesy of Bill Jenkins, Chief Scientist, GNAT first leg).
