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

The nets are 61 cm in diameter and have a cylindrical section 147 cm long and a conical section 153 cm long. Mesh sizes from 0.1 to 0.5 mm have been used, but normally 0.333 mm is used. A flowmeter is present in each hoop [Posgay and Marak (1980), Fig. 1]. |
