attribute	NC_GLOBAL	summary	String	Marine dissolved organic carbon (DOC) is one of the largest actively-cycling carbon reservoirs on earth—comparable in magnitude to atmospheric CO2 (Hansell 2013)—and thus is an essential component of the global carbon cycle. DOC has a multitude of sources, including phytoplankton productivity, grazing, excretion, solubilization from particulate organic matter (POM), viral lysis, and riverine input; the major DOC sink in the ocean is consumption by heterotrophic microbial communities (Carlson & Hansell 2015). Measurement of bulk DOC characteristics such as 14C age and molecular size have demonstrated that the high molecular weight (HMW) DOC fraction is generally younger and more biologically reactive than the low molecular weight (LMW) fraction (e.g. Guo et al. 1996; Walker et al. 2016). We know that a substantial fraction of HMW DOC consists of carbohydrates, including neutral sugars, and that its concentration is lower in the deep ocean than in the upper mesopelagic/surface ocean (Benner & Amon 2015). Characterization of the HMW DOC fraction has primarily used chemical measurements that provide information about monomeric constituents (Benner et al. 1992; Kaiser & Benner 2009), but yield no information on the order in which such constituents are linked together, or about the 3D structure of the intact HMW DOC. Beyond these observations and measurements, however, the specific factors controlling the rate, location, and extent to which DOC is transformed and remineralized by heterotrophic microbial communities in the ocean are still not well understood.   A key focus of this project's field work is investigating the potential of marine heterotrophic microbial communities from different water masses and under differing conditions of organic matter availability to hydrolyze six well-characterized high-molecular-weight (HMW) polysaccharides (arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan). To better contextualize this hydrolysis, bulk water characterization of the deep chlorophyll maximum (DCM), oxygen minimum zone (OMZ), and bottom waters used in our mesocosm incubation experiments was performed.     This dataset includes the measurement of carbohydrate microarray (epitope) analyses of POM-derived carbohydrates from bulk waters collected in the western North Atlantic Ocean aboard R/V Endeavor (EN638) during May 2019.    Note that the carbohydrate microarray data are only semiquantitative; while comparisons can be made for the abundance of a given epitope between stations and depths, the signal intensity cannot be used to compare signals of different epitopes, since the binding affinity for individual epitopes differs between antibodies.  Note also that analyses were performed for all sampled depths at all stations. There was, however,  no positive signal at depths that are shown as "0" in this dataset.
