The two data files for this project contain time, geographic location, 
environmental, and along-track data plus 10 variables of taxa/particle 
abundance for the high magnification camera and 4 variables of taxa/particle 
abundance for the low magnification camera. These variables include 
unidentified copepods, diatom rods, acantharia, UID_teardrop_shaped, 
oithona_spp, sarcodine, larvacean, UID_protozoa, UID_phytoplankton, 
nauplius, calanus copepods, all other taxa and marine snow.


Data are presented here as abundances (#/L) of each taxa or particle in
~ 5 second time intervals.  Along-track distance (km) is calculated from the 
geographic positions of the observations, in temporal order.  Bottom depth 
(m) was measured from the shipboard Knudsen Echo Sounder; these data are very 
noisy.  Position (latitude, longitude) logged from the ship's P-Code GPS.  
All other variables (pressure, temperature, salinity, density, fluorescence, 
light transmission, and PAR) were measured or calculated using sensors on the 
Video Plankton Recorder.  

Two programs, read_high.c and read_low.c (for VPR_highmag.cdf and 
VPR_lowmag.cdf, respectively) are located on the Tools page to aid 
in accessing the data from those files.
