Dataset: BIOMAPERII environmental data from the Video Plankton Recorder (VPR) data stream from RVIB Nathaniel B. Palmer cruises NBP0103 and NBP0104 in the Southern Ocean from 2001 (SOGLOBEC project)

BiomaperII Environmental data coincident with VPR data

 

These data are from the Environmental Sensing System (ESS) a component of 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). The incoming ESS environmental data is split into two data streams, one to be merged with the VPR data and one to be merged with the Acoustics data. There are times when either the Acoustic or VPR systems may be turned off. Thus, there is a independent ESS data set to support the Acoustic or VPR data streams.

These are the ESS environmental data from the VPR data stream.

These data are preliminary. Large outliers in the data have been removed. No comparison has been made with the data reported from the vertical CTD or water bottle stations. The depth data are very noisy because the instrument was sending out lots of spurious information and there has been no attempt to smooth it.
