Hello Argos User Community, 

If you missed us last month, you can access the Newsletter archive from the Past Issues button.

In this Newsletter we highlight Argos users and wildlife biologists Cathy Raley and Keith Aubry from the USDA's Forest Service sharing their story on collar tagging wolverines in Washington.

Best Regards,

Argos Goniometer Feedback w/ Rick Goetz
Rick Goetz (NOAA NWFSC) leased the Argos Goniometer for the month of May in order to recover pop-up satellite tags (model: SeaTag-MOD from Desert Star Systems). He is not alone as we have multiple Argos Goniometers out at any given time. Here's his anaylsis of how the Argos goniometer is a better tool than the custom-one he had built for the purpose.

Using the Goniometer Rick noted, "We got all the tags we went after....there were 4 tags in the open ocean about 25-30 miles off the Washington and Oregon coast."

From Rick:
- The unit I had made for me is very good, but it will not track specific tag IDs like the Goniometer which is a definitely an advantage if you are trying to sort out background hits from real ones when you are getting close to the tag.

- We felt that the Goniometer was about a mile more sensitive than the other unit, and it usually detected a tag before the other unit.

- The furthest out we detected a tag with it was probably 4 miles and that was in the open ocean with 5-6 foot swells and very little wind waves.

- I would say that the tag ID for the Goniometer is a real advantage and would be even more important if you had multiple tags in one area.

We want to thank Rick Goetz and his team for sending in his comparative review of the Goniometer. "We plan to use the Goniometer again...we like it!"
Argos User Spotlight: Cathy Raley & Keith Aubry
Cathy Raley (wildlife biologist) & Keith Aubry (research wildlife biologist) wanted to share the project they have worked on for the last ten years. Their study species was the wolverine, and the work they have done is significant in many ways.

For starters, wolverine populations in the contiguous U.S. are being evaluated by the U.S. Fish and Wildlife Service to determine if they should be listed under the Endangered Species Act. In addition, prior to 2006 when they began their work, no other satellite tracking study had been conducted on wolverines in this area.

Cathy noted, "Without the Argos system, a study like this would not have been feasible."

Argos satellite data from 14 collared individuals showed that resident wolverines in the study population occupied an area of about 8,221 km2 extending from Manning Provincial Park in southern British Columbia south to the Wenatchee Lake area in Washington State. In one case a male traveled distances greater than 564km, suggesting that the study population might be connected with wolverines in the Coast Range of British Columbia.

The full story including why collar selection is important, how duty cycle was chosen, and the importance of the study can be found here.
Cathy and Keith are both with the Pacific Northwest Research Station (United States Department of Agriculture, Forest Service) located in Olympia, Washington.
