The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson
attribute NC_GLOBAL acquisition_description String 15NO3- uptake rates were determined daily during experimental cycles from
samples incubated on the in situ array at 8 depths spanning the euphotic zone.
Each day samples were collected from Niskin rosette into polycarbonate bottles
(a single 1.2-L bottle per depth). Samples were spiked with K15NO3 (final
concentration 0.100 umol L-1). All samples were incubated in situ for 24 hours
beginning and ending at ~04:00 am local time. Upon recovery, 5NO3 uptake
samples were immediately filtered through pre-combusted GF/F filters at low
pressure and frozen in liquid nitrogen. On land, they were thawed, acidified,
dried out, and analyzed by mass spec at the SIO Analytical Facility.

attribute NC_GLOBAL instruments_0_description String A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24 or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

attribute NC_GLOBAL projects_0_description String Research was aimed at improved understanding of plankton dynamics, carbon and nutrient fluxes,�and potential trace element limitation in the Costa Rica Dome region of the eastern tropical Pacific. The specific science objectives of the 2010 R/V Melville cruise (MV1008) were:
1) to assess grazing and trace metal/nutrient controls on primary production and phytoplankton standing stocks;
2) to quantify carbon and elemental fluxes and export rates from the euphotic zone; and
3) to measure microbial population, processes, stable isotope abundances associated with the OMZ and nitrite maxima.
Additional information about MV1008 can be found in the cruise report (PDF).
NOTE: The original proposal and award abstract are not relevant. The project was originally funded by NSF as experimental tests of phytoplankton controls in the Arabian Sea. Piracy concerns in the region led to the cancellation of the research cruise in 2009, and a Change of Scope request was approved to focus the project on related issues in the Costa Rica Dome (CRD).
Though this project is not formally affiliated with any large program,�it aligns with IMBER's emphasis on community ecology and biogeochemistry, and the OCB focus on carbon-based measurements of production, grazing and export processes.
