Description

haul factor, used to calculatue displacement volume, 100/volume filtered (m3)

DatasetPI-Supplied DescriptionPI-Supplied Name
Bongo displacement volume data from R/V Albatross IV, R/V Endeavor, and R/V Oceanus during U.S. GLOBEC Georges Bank broadscale cruises to Georges Bank and the Gulf of Maine in 1995-1999 (GB project)haul factor. A standard haul factor (SHF) was calculated for each Bongo net tow to make them comparable and to allow estimation of areal abundance. The SHF is calculated by the formula: SHF = 10D/V where D = depth of haul = cosine of the average angle of stray of the towing cable multiplied by cable length (m) V = total volume of water (m3) strained during the haul. V = R * a * p where R = total number of revolutions of the current meter during the haul a = area (m2) of the mouth of the net p = length of the column of water needed produce one revolution of the current meter haul_factor
