Description

Marine Mammal Observers mitigate for the potential impact of sound exposure on marine fauna during geophysical surveys, naval active-sonar exercises, UXO clearance or civil engineering projects.

This app will assist the MMO making mitigation decisions by calculating the distance from the animal to the source of acoustic interference using a trigonometric cosine function. The MMO simply enters the distance and bearing to the TARGET and SOURCE from their observation position and the app calculates the rest.

This app is loaded with features to make allow to keep focused on the detection (See the user manual for a detailed description):
Fix compass bearing to animal and source by pointing device and pressing button.
Convert binocular reticules to distance by entering the number of reticules between horizon and animal and pressing the reticule button (per formulae in Lerczack and Hobbs, 1998).
Set up to 3 unique observation locations to define height above sea level (required for accurate reticule conversion).
Save data to the log for each sighting and export in .csv format for your own mapping and analyses needs.
Shows vessel position, mitigation zone and projected fauna sightings on the map. Map also displays latitude, longitude, course and speed.
Press the radar button and the map will orientate to the vessel point of view. Sightings labels will be updated live with the distance to source and the bearing from the vessel for ease of re-sighting.
Fully customise the MMO parameters. Specify anything from your binocular MILs per reticule, mitigation zone size, choose a ramform hull as your maps ship symbol and much much more!

Disclaimer:
MMO Range Finder App should be used as a reference tool and is only as precise as the users ability to range find. Any decision making is the responsibility of the user. If in use, the compass and GPS location should be verified often.

What’s New

Version 4.0.1

This latest update to the MMO Range Finder includes the following (and much much more!)

Now equipped with maps. Your sightings can be displayed on a map with your ship and mitigation zone.
Choose between conventional, 'x-bow' and 'ramform' ship symbols for the map, all correctly scaled to the real ship dimensions.
Press the radar button to show the map orientated to the vessel heading.
Radar button also displays the distance from the target to the center of source as well as the bearing from the ship to the target for ease of re-sighting.
Compass direction indicator guides you back to your sighting.
Swipe left on any text-field to delete.
Your data can be saved to the log and exported as a .csv using a variety of methods (email, Dropbox, iCloud, etc).
A user manual for the MMO Range Finder can be accessed from the app.
All app settings are now found within the app. User does not need to leave app to make changes.
Added option to calculate the great circle distance between the target and source when GPS is enabled.
Bug fixed related to pressing reticule converter button more than once.
