The Hydrobios Multinet system is equipped with 5 plankton nets which are opened and closed consecutively during the upcast while towed behind the ship at about 1.5 knots. Net number ("NetNr"), cumulative cubic meters of water filtered per net ("Flow1(m3)"), depth in meters ("Depth(m)"), temperature in degrees Centigrade ("Temp({SYMBOL 198 \f "Symbol"}C)") and conductivity in milliSiemens ("Cond(mS)") were recorded every 1 to 10 seconds as given by the "Sample interval (s)", and stored as ASCII-files. Only the raw uncalibrated data are given here; "NetNr" = 1 = no net, i.e. prior to opening the first net, whereas 2, 4, 6, 8 and 9 represent the first to fifth net, respectively. These data are not to be used without the prior (written) permission of G.A. Brummer, NIOZ, TEXEL, THE NETHERLANDS E-Mail: BRUMMER@NIOZ.NL
