attribute NC_GLOBAL acquisition_description String MARMAP used mainly a fixed station design covering the sample area of each\nsurvey approximately evenly (Sibunka and Silverman 1984, 1989).\\u00a0 EcoMon\nsampled the same spatial extent of the shelf as MARMAP, but used a random-\nstratified design based on the NEFSC bottom trawl survey design (Azarovitz\n1981). The number of plankton strata (n = 47) is lower than the bottom trawl\nsurvey (n = 108) as the narrow inshore stratum and the offshore shelf-break\nstratum of the bottom trawl survey (Azarovitz 1981) are combined in the EcoMon\nplankton sampling design.\\u00a0 The area encompassed by each stratum\ndetermined the number of samples in that stratum.\\u00a0 The number of stations\nsampled during an EcoMon survey is approximately 30 % less than that of\nMARMAP.\\u00a0 Samples were collected four to eight times per year (primarily:\nJanuary-February, March-April, May-June, July-August, September-October, and\nNovember-December) for each program (Richardson et al. 2010).\n \nThe basic station protocols were very similar for MARMAP and EcoMon (Jossi and\nMarak 1983, Ejsymont and Sherman 2000).\\u00a0 Samples were collected both day\nand night using a 61-cm bongo.\\u00a0 Net tow speed was approximately 1.5\nknots. Double oblique tows were a minimum of 5-mintues in duration, and fished\nfrom the surface to within 5-m of the seabed or to a maximum depth of 200-m.\nThe volume filtered of all collections was measured with mechanical flowmeters\nmounted across the mouth of each net. Mesh size of the net differed between\nthe programs, and was 505-\\u03bcm during MARMAP and 333-\\u03bcm during\nEcoMon.\\u00a0 Samples were preserved in 5% formalin.\n \nProcessing of most samples was conducted at the Morski Instytut Rybacki in\nSzczecin, Poland; the remaining samples were processed at the NEFSC or the\nAtlantic Reference Center, St Andrews, Canada. Larvae were identified to the\nlowest possible taxon and enumerated for each sample. Plankton tows differ\nwith respect to volume of water filtered and maximum tow depth. In order to\nmake data values comparable, these values were normalized through the use of a\nstandard haul factor: h = z * 10 / v, where z = maximum tow depth (in meters)\nand v = volume of water filtered (in meters cubed). Taxon abundance for each\nstation was standardized to number under 10 \\u2022 m-2 sea surface (Morse\n1989).\n \nReferences:  \n Azarovitz TR. 1981.
