Batfish |
 | | The Batfish can dive or ascend by rotating its hydroplanes ("wings") on ship command, and is capable of diving between the surface and approximately 400 m. |
 | | The Batfish was developed at the BEDFORD INSTITUTE OF OCEANOGRAPHY, Dartmouth, NS, and manufactured by Guildline Instruments Ltd, Smiths Falls, Ontario. |
 | | It is equipped with 3 sensors: a conductivity-temperature-depth probe, used to measure physical oceanographic features; a fluorometer (mounted atop the Batfish), measuring chlorophyll a fluorescence, the indicator of phytoplankton or plant biomass; and an electronic zooplankton counter (mounted below the Batfish), measuring small marine animals (approximately 0.5-4 mm long) which consume mainly marine plants. |
