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)

<p>This dataset was derived from the <a href=\"http://osprey.bco-dmo.org/dataset.cfm?id=10606&amp;flag=view\" target=\"_blank\">VPR_ashjian_orig_SO</a> 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.</p>

<h3>Video Plankton Recorder Data</h3>

<p>These data are from images of plankton and particles collected using the Video Plankton Recorder (VPR), a camera system mounted on the <u>BIO </u>-Optical <u>M</u>ulti-frequency <u>A</u>coustical and <u>P</u>hysical <u>E</u>nvironmental <u>R</u>ecorder (BIOMAPER II)¹ data acquisition system.</p>

<p>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).&nbsp;</p>
