attribute NC_GLOBAL acquisition_description String Methods for the Collection and Measurement of the Spectral Absorption
Coefficient (ag\u03bb) of Chromophoric Dissolved Organic Matter (CDOM):
Seawater samples for the measurement of chromophoric dissolved organic
matter (CDOM) absorption (ag) are filtered under a gentle vacuum (<5 in Hg)
through precombusted (6 hours at 450\u00b0C) Whatman GF/F glass fiber filters
and collected directly into pre-cleaned and pre-combusted sample glass
bottles. Samples for determination of CDOM spectral absorption coefficients
are stored under refrigeration at 4\u00b0C. In the laboratory, CDOM samples
are warmed to room temperature and filtered through 0.2 \u03bcm Whatman
Nuclepore polycarbonate filters or Gelman Supor (polyethersulfone) filters
prior to analysis (Mitchell et al. 2000). Filtration samples through GF/F
filters is necessary for coastal ocean waters due to the high particle load
that quickly clog Nuclepore and Supor filters. Absorption spectra of CDOM are
measured using a multiple pathlength, liquid core waveguide (MPLCW) system
(World Precision Instruments, Inc., Sarasota, FL) with UV oxidized Milli-Q
water as a reference (Miller et al., 2002). CDOM absorbance spectra are
measured between 370 and 725 nm at 1 nm intervals normalized to the reference
spectrum.

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).
