The Batfish was an innovation in oceanographic sample and data gathering. This hydrodynamic towed vehicle became a key scientific tool in the 1970s as Canada explored the oceans within its expanded 200-mile boundaries. It was towed behind the CSS Hudson, Canada’s main research vessel at the time. - Function
-
This is the upper half of the hull of the Batfish. It was used as a vehicle to mount sensors for gathering oceanographic data about temperature, salinity and plankton concentration. It was towed behind a ship and controlled remotely to vary its depth between 0 and 300 m. (Ref. 1) - Technical
-
The Batfish worked together with the PDP-8 computer onboard the CSS Hudson to study data in real time. It and controlled remotely to vary its depth between 0 and 300 m. There were operational challenges related to the towing line. On one occasion, a miscalculation while trying to give Batfish more cable to swim further and deeper led to tangling of the cable. When this was overcome, scientists were able to send the Batfish deeper than before (down to 500 m). - Area Notes
