New Mysticetus, version 184.108.40.206 – http://www.mysticetus.com
This new version has a couple of exciting features:
First up, Mysticetus now supports multiple vessel tracking through AIS devices that output the NMEA AIVDM sentence. Simply plug in your AIS receiver to the PC and Mysticetus will display all vessels in your system. Just for kicks (and some hard-core testing) I found a data stream on the internet of hundreds of large vessels roaming about various waterways and oceans. Here is a shot of them at one instant in time. Mysticetus will, of course, keep the map updated with the location, course and speed of all the survey craft in your system. If you enable tracking on a vessel, Mysticetus will leave a track behind that vessel.
Next up, Mysticetus now has some tools to support the calculation of harassment “takes” when related to seismic operations. Mysticetus does not do any kind of super-sophisticated AIM (Acoustics Integration Model) work (yet…just starting to research it…I need a few days to get up to speed), but for now does do some fairly complex geo-polygon-based calculations to derive estimated “take” values based on variables such as sound propagation with respect to depth under the vessel as the vessel travels along a planned route. Mysticetus takes into account varying levels of population density based on geographic location as well as seasonal differences.
Mysticetus can also calculate “take” based on actual GPS track taken by the vessel so comparisons between planned and actual can be performed.
And, of course, all of this is completely configurable (sound levels, ensonification distances by depth, population densities, etc.)
Here is an example of some planned seismic lines, along with their corresponding ensonification regions. Note that the width of the polygons changes with depth beneath the vessel.
Here is another look, this time of some of these in Google Earth (which actually does a better job displaying the polygons for report/printing purposes – as always, Mysticetus can export all information to Google Earth)
Finally, Mysticetus has some significant performance improvements in the way the shaded relief maps are drawn. They draw 2-3 as quickly as the previous version. I can’t really show that in a blog post, so here’s a picture of our new dog, Tesla, instead:
As always, send feedback and feature suggestions my way.
Hope you have a great holiday season, and get just the perfect amount of snow for wherever you are.
