each assigned to a different portion of the mooring or to a different portion of the water column
on separate moorings. Another approach would be multiple deployments of a single profiler,
each of 3 to 6 months duration. In either case, cost becomes an additional constraint.
The third iteration is a reasonable solution. Further refinement of the original
requirements might point to a longer burst or some other variation. This example demonstrates
how deployment parameters are iteratively selected and programmed. Importantly, it also
demonstrates the tradeoffs that are part of planning a long duration, deep-water, MMP
deployment.
Shallow-Water Deployment
The second example illustrates a hypothetical deployment on the continental slope with a
profiling range of several hundred meters.
Consider these initial requirements for a deployment on the continental slope:
• Park at the bottom
The DOS file system limits the number of files that can be stored in the root directory of
the flash card to 4096. The ‘Profiles/file set’ option increases the number of profiles that can be
conducted by allowing you to store multiple profiles as a single data file. This option is
particularly useful for shallow-water deployments.
• Twelve month deployment duration, 2 turn-around cruises are allowed
• Sample at the highest possible rate, no less frequently than a profile every 3
hours
• Profile between 25 meters and 200 meters
