attribute NC_GLOBAL acquisition_description String Mesozooplankton net collections  \n Mesozooplankton sampling was conducted using a standard 1-m2 ring net with\n202-um Nitex mesh, towed obliquely for 20 min at a ship speed of 1-2 kts. A\nGeneral Oceanics flowmeter was attached across the net mouth to record volume\nfiltered, and a Vemco depth meter was fastened to the net frame to record tow\ndepth and duration. The target depth of tows was 150m. Once on deck, the net\nwas washed down with seawater and the contents of the cod end placed in a\nbucket with carbonated water to prevent gut evacuation. Separate splits (each\nof typically 1/8th of the sample) were used for biomass and gut-fluorescence\ndeterminations, with the latter done first to minimize pigment degradation.\nEach of these subsample splits was wet sieved into five size classes of\n0.2-0.5, 0.5-1, 1-2, 2-5, and >5 mm.\n \nGut pigment and grazing estimates  \n Each size-fractioned sample for gut pigment analysis was concentrated onto a\n47-mm 202-um Nitex filter and immediately frozen in liquid nitrogen for\nprocessing on shipboard or in the lab. The filters were subsampled for the\nthree smallest size classes, by placing the frozen filters centered under a\nplastic template and sectioning into 8 pie-shaped fractions with a thin knife\nblade. Analyses were carried out in duplicate. The replicate 1/8th samples\nwere ground in 90% acetone using a sonicator to extract pigments, and the\nhomogenate was centrifuged to remove particulates. For the 2-5 mm size class,\ntypically the whole sample was processed, although if very dense a smaller\nsubsample was taken. The >5 mm size class was always processed in its\nentirety. Concentrations of chlorophyll a (Chl a) and phaeopigments (Phaeo)\nwere then measured using a Turner 10AU fluorometer.\n \nFor each size-fraction analyzed, the investigators computed the depth-\nintegrated grazing rate (GR) using phaeopigments only to obtain conservative\nrates. The GR was calculated in the euphotic zone as:\n \nGR = [ (pig * D) / (vol * f) ] * K\n \nwhere GR is the grazing rate (ug m-2 h-1), pig is the measured pigment value\n(ug, based on phaeopigments), f is fraction of sample analyzed, D is depth of\ntow (m), vol is the volume of water filtered (m3), and K is the gut evacuation\nrate constant. For K, the investigators used the rate constant of 2.1 h-1\nderived from shipboard gut evacuation experiments at 140\\u00b0W during the\nJGOFS EqPac program, which had similar temperatures as those encountered in\nthe CRD.

attribute NC_GLOBAL instruments_0_description String A Ring Net is a generic plankton net, made by attaching a net of any mesh size to a metal ring of any diameter.  There are 1 meter, .75 meter, .25 meter and .5 meter nets that are used regularly. The most common zooplankton ring net is 1 meter in diameter and of mesh size .333mm, also known as a 'meter net' (see Meter Net).

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:\n1) to assess grazing and trace metal/nutrient controls on primary production and phytoplankton standing stocks;\n2) to quantify carbon and elemental fluxes and export rates from the euphotic zone; and\n3) to measure microbial population, processes, stable isotope abundances associated with the OMZ and nitrite maxima.\nAdditional information about MV1008 can be found in the cruise report (PDF).\nNOTE: 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).\nThough 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.
