attribute NC_GLOBAL acquisition_description String Methods are summarized below. Detailed methods for all data collected as part
of this study can be found in the publications arising from this study
(references given below).

On each BATS cruise, aquasi-lagrangian sampling scheme is employed. An in situ
primary productivity array is deployed from dawn to dusk. The biogeochemistry
and biological parameters reported in this data were measured from Niskin
bottle water samples.

Bacterial production was measured using [3H-methyl] thymidine incorporation
and converted to carbon-based bacterial production using standard equations.
Bacterial abundance was determined using DAPI stained epifluorescence
microscopy. Pico-autotrophs were identified as either Synechococcus and

Samples for NO3/NO2, NO2 and PO4 are filtered and frozen (-20 degrees C) in
HDPE bottles until analysis. Total organic carbon (TOC) and total nitrogen
were determined using high temperature combustion techniques. Total phosphorus
concentrations are quantified using a high temperature/persulfateoxidation
technique. Particulate organic carbon (POC) and nitrogen (PON) samples were
filtered on precombusted Whatman GF/F filters and frozen until analysis on an
elemental analyzer. Particulate phosphorus samples were analyzed using an ash-
hydrolysis method with oxidation efficiency and standard recovery checks.

Sample QA/QC procedures followed those given in the associated manuscripts. At
the point of collection, any leaking niskin bottles were noted on the master
cast sheets and samples were taken from a different niskin fired at the same
depth as the leaking bottle. No data are reported for leaking Niskin bottles.
During sample analysis, certified standards, where available, were carefully
examined to ensure that they were consistent with expectations for accuracy
and precision. If no obvious error or problem was found, the data were
considered OK and in the range of environmental data that this study hoped to

Sample accuracy was assessed by using certified standards, for those
measurements where standards are available. Certified standards were run with
each analytical run and compared to long term control charts for respective
analyses. For those analyses where there are no standards (e.g., flow
cytometric cell counts) data were assessed for reasonableness based upon
extensive experience of the PI\u2019s.

attribute NC_GLOBAL projects_0_description String Fluxes of particulate carbon from the surface ocean are greatly influenced by the size, taxonomic composition and trophic interactions of the resident planktonic community. Large and/or heavily-ballasted phytoplankton such as diatoms and coccolithophores are key contributors to carbon export due to their high sinking rates and direct routes of export through large zooplankton. The potential contributions of small, unballasted phytoplankton, through aggregation and/or trophic re-packaging, have been recognized more recently. This recognition comes as direct observations in the field show unexpected trends. In the Sargasso Sea, for example, shallow carbon export has increased in the last decade but the corresponding shift in phytoplankton community composition during this time has not been towards larger cells like diatoms. Instead, the abundance of the picoplanktonic cyanobacterium, Synechococccus, has increased significantly. The trophic pathways that link the increased abundance of Synechococcus to carbon export have not been characterized. These observations helped to frame the overarching research question, "How do plankton size, community composition and trophic interactions modify carbon export from the euphotic zone". Since small phytoplankton are responsible for the majority of primary production in oligotrophic subtropical gyres, the trophic interactions that include them must be characterized in order to achieve a mechanistic understanding of the function of the biological pump in the oligotrophic regions of the ocean.
This requires a complete characterization of the major organisms and their rates of production and consumption. Accordingly, the research objectives are: 1) to characterize (qualitatively and quantitatively) trophic interactions between major plankton groups in the euphotic zone and rates of, and contributors to, carbon export and 2) to develop a constrained food web model, based on these data, that will allow us to better understand current and predict near-future patterns in export production in the Sargasso Sea.
The investigators will use a combination of field-based process studies and food web modeling to quantify rates of carbon exchange between key components of the ecosystem at the Bermuda Atlantic Time-series Study (BATS) site. Measurements will include a novel DNA-based approach to characterizing and quantifying planktonic contributors to carbon export. The well-documented seasonal variability at BATS and the occurrence of mesoscale eddies will be used as a natural laboratory in which to study ecosystems of different structure. This study is unique in that it aims to characterize multiple food web interactions and carbon export simultaneously and over similar time and space scales. A key strength of the proposed research is also the tight connection and feedback between the data collection and modeling components.
Characterizing the complex interactions between the biological community and export production is critical for predicting changes in phytoplankton species dominance, trophic relationships and export production that might occur under scenarios of climate-related changes in ocean circulation and mixing. The results from this research may also contribute to understanding of the biological mechanisms that drive current regional to basin scale variability in carbon export in oligotrophic gyres.
