About the C-POD

C-PODThe C-POD uses digital waveform characterisation to select clicks and logs the time, centre frequency, intensity and bandwidth of each cetacean click. The main advantages over the T-POD are:

  • the false positive rate, which is already very low for T-PODs, will be even lower.
  • T-PODs sometimes do not log clicks from dolphins because the clicks are too broadband and accepting such clicks would flood the memory. The C-POD will log these clicks.
  • the software will be better able to distinguish the trains arising from individual cetaceans and will be able to distinguish several different groups of species.
  • the frequency range, 20-160 kHz, means they will log all odontocetes continuously (except sperm whales).
  • due to their low power requirements, C-PODs can run for 4 months on 8 alkaline D-cells.
  • a removable Secure Digital (SD) memory card which allows much more data to be collected.
  • rapid servicing at sea as no computer is required for downloading data from the POD.
  • very few user-controlled settings required so that comparable data can be captured in different studies.
  • tighter standardisation so that small trends over time can be identified.
  • like T-PODs they will be buoyant and consequently self-orientating.

Data is analysed using the C-POD PC software. The train filter developed as part of the software will improve species identification as more data becomes available and all software improvements will be retrospectively applicable to all data sets and new versions of the C-POD software will be available to users free of charge, so that data can be re-analysed.
