 The
C-POD uses digital waveform characterisation to select cetacean clicks and logs the
time, centre frequency, sound pressure level, duration and bandwidth of each click. The main advantages
of the C-POD are:
- the false positive rate is very low.
- the C-POD will log the broadband clicks of dolphins without flooding the memory.
- the software is continuously being developed to distinguish the trains arising from
individual cetaceans and different
groups of species.
- the frequency range, 20-160 kHz, means that C-PODs 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 large volumes of data to be collected.
- rapid servicing at sea is possible because no computer is required for downloading data
from the POD.
- very few user-controlled settings are required so that comparable data can
be captured in different studies.
- tight standardisation ensures that small trends over time can be
identified.
- C-PODs are 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. 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.
