Dataset: Video Plankton Recorder data where values reported as zero or nd have been removed from display; from RVIB Nathaniel B. Palmer cruises NBP0103, NBP0104, NBP0202 in the Southern Ocean from 2001-2002 (SOGLOBEC project)

This dataset was derived from the VPR_ashjian_orig_SO dataset. In the 'nonzero' dataset, values of both 0 and nd (no data) in the abund_L column (taxon abundance) have been removed in order to allow the dataset to be mapped.

Video Plankton Recorder Data

These data are from images of plankton and particles collected using the Video Plankton Recorder (VPR), a camera system mounted on the BIO -Optical Multi-frequency Acoustical and Physical Environmental Recorder (BIOMAPER II)¹ data acquisition system.

BIOMAPERII is a towed package consisting of a number of independent observational components: a multi-frequency sonar (Acoustics) system, a video plankton recorder (VPR) system, and an environmental sensor system (ESS). 

Companion object:  biomaperII.
