attribute NC_GLOBAL acquisition_description String The MOCNESS-1 plankton sampler has nine rectangular nets (1m x 1.4 m) with a\nmesh size of 0.333 mm, which are opened and closed sequentially by commands\nthrough conducting cable from the surface (Wiebe et al., 1976).\n \nBiomass (wet weight) and abundance were determined principally by silhouette\ndigitization of taxa lengths and conversion to equivalent wet weights\naccording to the equations and methods adapted from Davis and Wiebe (1985) and\nWiebe et al. (2004). New formulas were calculated for Southern Ocean krill\nbecause the length-weight relationship (Wet Weight = 0.0054*Length3.214)\ndiffered from that of the North Atlantic euphausiids (Wet Weight =\n0.0138*Length3.071; Davis and Wiebe, 1985).\n \nMOCNESS Sample Analysis\\u00a0(from Ashjian et al., 2004)\n \nSilhouette photographs first were obtained from each sample; this photograph\nthen was scanned with an Epson Expression 1600 scanner at 1200 dpi to produce\na Tagged Image File Format (TIF) image. Identification and measurement of\norganisms from the tiff image were accomplished manually using the specialized\nMATLAB (Mathworks, Inc.) routine, the WHOI Silhouette DIGITIZER (v 1.0)\n(Little and Copley, 2003). A scanned photographic image of an aliquot of a\nsample was displayed with a superimposed reference grid on the computer\nscreen. The operator identified each organism to taxonomic and/or size\ncategory by selecting the appropriate category button. Organism lengths (both\nstraight and curved) then were measured by the operator using the cursor on\nthe computer screen. Although the nominal resolution of the measurement is\n0.02 mm, in practice the resolution was ~0.05 mm. In instances where there\nwere too many organisms of a given type to justify measuring every individual\norganism, the DIGITIZER routine generated a list of randomly located cells to\nsystematically sub-sample the overall image. Each organism's biomass was\ncalculated automatically from its length measurement using the appropriate\nlength-weight relationship.\n \nThis is a graph of the vertical distribution of biomass from the Winter 2001\nCruise, NBP0103. Net 8 is closest to the surface and net 1 is deepest:\n \n \nThis is a graph of the vertical distribution of biomass from the Winter 2001\nCruise, NBP0104:\n \n \n  \nFigure 1. Map of Tow locations, Fall and Winter, 2001\n \nTable 1. Summary of locations, times, and depths for the twelve net tows.  \n (Note: Winter tows 14 and 15 were considered one tow because when ice and\nmalfunction led to no data in the top three nets of Tow 14, MOC Tow 15 was\nfished in the upper 90 meters to compensate.)\n Cruise | Region | Tow  \n \\t\\t\\tNumber | Date | Time  \n \\t\\t\\t(Local) | Light* | Lat(S) | Lon(W) | Tow Depth(m) | Bottom\nDepth(m) | Ice Cover  \n \\t\\t\\t(tenths)   \n---|---|---|---|---|---|---|---|---|---|---  \nFall | Offshore | 6 | 05/04/01 | 1332 | D | 66\\u00a0 40.17 | 73\n22.08 | 0-1001 | 3650 | 0   \n\\u00a0 | Midshelf 1 | 1 | 04/30/01 | 2050 | N | 66 10.80 | 69 10.47 |\n0-306 | 360 | 0   \n\\u00a0 | Midshelf 2 | 3 | 05/02/01 | 0320 | N | 66 48.53 | 70 21.42 |\n0-348 | 600 | 0   \n\\u00a0 | Midshelf 3 | 12 | 05/13/01 | 1830 | N | 68\\u00a0 23.62 | 72\n18.44 | 0-356 | 400 | 0   \n\\u00a0 | Midshelf 4 | 16 | 05/18/01 | 0854 | N | 68\\u00a0 59.43 | 74\n55.77 | 0-340 | 350 | 0   \n\\u00a0 | Marguerite Bay | 24 | 05/29/01 | 0300 | N | 67 55.33 | 68\n30.69 | 0-602 | 690 | 0   \nWinter | Offshore | 11 | 08/11/01 | 0918 | T | 67 14.69 | 74 25.27 |\n0-989 | 2917 | 10   \n\\u00a0 | Midshelf 1 | 17 | 08/26/01 | 0306 | N | 66 11.13 | 69 06.21 |\n7-305 | 346 | 6   \n\\u00a0 | Midshelf 2 | 4 | 07/31/01 | 0949 | D | 66 45.18 | 70 09.64 |\n11-413 | 501 | 8   \n\\u00a0 | Midshelf 3 | 13 | 08/17/01 | 2117 | N | 68 13.21 | 72 56.53 |\n0-230 | 325 | 10   \n\\u00a0 | Midshelf 4 | 14 | 08/21/01 | 1136 | D | 69 15.55 | 75 34.00 |\n20-290 | ~340 | 7   \n\\u00a0 | \\u00a0 | 15 | 08/22/01 | 0327 | N | 69 12.30 | 75\\u00a0\n43.90 | 0-91 | ~350 | 9   \n\\u00a0 | Marguerite Bay | 9 | 08/08/01 | 0215 | N | 67 53.74 | 68\n10.82 | 0-488 | 600+ | 9   \n*Light conditions are designated as:  \n \\\"D\\\" = day, sunlight present;  \n \\\"N\\\" = night, darkness;  \n \\\"T\\\" = twilight

attribute NC_GLOBAL instruments_0_description String The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. The MOCNESS-1 carries nine 1-m2 nets usually of 335 micrometer mesh and is intended for use with the macrozooplankton.  All nets are black to reduce contrast with the background.  A motor/toggle release assembly is mounted on the top portion of the frame and stainless steel cables with swaged fittings are used to attach the net bar to the toggle release.  A stepping motor in a pressure compensated case filled with oil turns the escapement crankshaft of the toggle release which sequentially releases the nets to an open then closed position on command from the surface. -- from the MOCNESS Operations Manual (1999 + 2003).

attribute NC_GLOBAL projects_0_description String The fundamental objectives of United States Global Ocean Ecosystems Dynamics (U.S. GLOBEC) Program are dependent upon the cooperation of scientists from several disciplines. Physicists, biologists, and chemists must make use of data collected during U.S. GLOBEC field programs to further our understanding of the interplay of physics, biology, and chemistry. Our objectives require quantitative analysis of interdisciplinary data sets and, therefore, data must be exchanged between researchers. To extract the full scientific value, data must be made available to the scientific community on a timely basis.

attribute NC_GLOBAL projects_1_description String The U.S. Global Ocean Ecosystems Dynamics (U.S. GLOBEC) program has the goal of understanding and ultimately predicting how populations of marine animal species respond to natural and anthropogenic changes in climate. Research in the Southern Ocean (SO) indicates strong coupling between climatic processes and ecosystem dynamics via the annual formation and destruction of sea ice. The Southern Ocean GLOBEC Program (SO GLOBEC) will investigate the dynamic relationship between physical processes and ecosystem responses through identification of critical parameters that affect the distribution, abundance and population dynamics of target species. The overall goals of the SO GLOBEC program are to elucidate shelf circulation processes and their effect on sea ice formation and krill distribution, and to examine the factors which govern krill survivorship and availability to higher trophic levels, including penguins, seals and whales. The focus of the U.S. contribution to the international SO GLOBEC program will be on winter processes. This component will focus on juvenile and adult krill and mesozooplankton prey distribution and abundance using a sophisticated instrument package, BIOMAPPER II, which is equipped with an acoustic backscatter sonar system, a video plankton recorder and an environmental sensor system. The system is used in large-scale studies. Additionally, a remotely-operative vehicle will be used to map the distribution and behavior of krill under ice. The result of the integrated SO GLOBEC program will be to improve the predictability of living marine resources, especially with respect to local and global climatic shifts.
