Methods for tracking fine scale underwater movements of marine mammals around marine tidal devices

This report reviews possible technological methods for tracking fine scale underwater movements of marine mammals around marine tidal devices.


Footnotes

1. Active acoustic tags are discussed in the Passive Acoustic Monitoring - Section 3.3.

2. These procedures require an appropriate Animals (Scientific Procedures) Act 1986 license.

3. The Iridium satellite system ( http://www.iridium.com/default.aspx) may have the potential to become a candidate data relay system. However its practical application in marine mammal telemetry has yet to be demonstrated.

4. http://www.smru.st-andrews.ac.uk/Instrumentation/Products/ Currently SMRU Instrumentation is the only provider of this type of tag functionality.

5. The data are sent using a FTP protocol over a General Packet Radio Service ( GPRS) link.

6. We estimate that the current vector prediction should be (+- 0.2m/s, +- 5°) of truth and available at a spatial (x, y, z) scale of 5-10m.

7. For example the C-POD ( http://www.chelonia.co.uk).

8. SMRU Ltd is developing useful functionality in this area to support its PAMBOUY products

9. Examples include: http://www.vemco.com/, http://www.oceantracks.csiro.au/tags-acoustic.html, http://atstrack.com/Generic-84-Acoustic-Fish.aspx, http://www.htisonar.com/index.htm, http://www.lotek.com/acoustic-positioning-software.pdf, http://atstrack.com/Generic-112-Systems-Acoustic-Fish.aspx

12. http://www.tritech.co.uk/product/gemini-720i-300m-multibeam-imaging-sonar

13. This will require about two weeks of programmer effort.

14. For example the Hitachi KP-DE500 Ultra High Sensitivity Camera.
