PLEASE NOTE there is discrepancy between the content of actual data in this accession and the abstract information that was present in Thaila folder for this accession. Following abstract is based on the information from Thaila folder. MECCAS II (Microbial Exchanges and Coupling in Coastal Atlantic Systems) cruise data collected by the R/V Gyre at the mouth of the Chesapeake Bay. Each of four MECCAS cruise data sets is divided into 3 files: File 1 contains underway surface mapping data. 12 parameters measured included location, temperature, salinity, ammonium, nitrate, nitrite, phosphate, and silicate at +/- 0.03-0.1 uM. File 2 contains vertical profiles at stations along mapping routes; the same 12 parameters as described above were measured. File 3 contains vertical profiles at drogue stations; 96 parameters were measured. Parameters include CTD data, zooplankton data (biomass, heterotrophic and autotrophic grazing rates, and production rate estimates), bacteria data (cell count, estimated volume, nutrient assimilation, and production rate estimates), and nanoplankton data (abundance of pigmented and non-pigmented eukaryotes and estimates of bacterial removal rates). Nutrient data contained in File 3 includes dissolved free amino acids (carbon content in free glutamic acid, serine, glycine, and alanine).
