Bioness Net Control System

A full featured net control system, capable of operating a variety of multiple net zooplankton samplers.
Designed to interface with a variety of common CTD’s, including Sea-Bird, AML and FSI.
Most other makes of CTDs can be accommodated.
The Bioness Control System can be easily retrofitted to many existing net systems.

Deck Software

Controls net operations in real time (with conductive tow cable)
Programs data logger for autonomous operation (time, ascending or descending depth)
Displays CTD data in graph form
Calculates and displays:
All sensors in real engineering numbers
Net drops and net drop confirmation
Pitch, net efficiency and speed
Swept volume by net
Net number and time open
Records real time or uploaded data to disk
Replays archived data files through the graphical interface
Converts raw data run files to comma delimited converted files
Generates converted data files for each net in a tow
Embeds station data, system settings and coefficients in the data file
User settable sensor coefficients
Windows 95-98, ME, 2000 and XP compatible

Data Logger

Executes commands issued from the surface (e.g. net drop)
Controls autonomous operations
Records all run data on industry standard flash card memory
Date and time stamps data, holds longitude and latitude data
Plug & Play compatible with many CTDs, including up to 4 optional channels
