Pressure gage water data collection

Field training on how to measure water level using a pressure gage for a flowing well in Sis, Armenia.

The growth of aquaculture to raise trout, sturgeon and other cold-water fish has increased withdrawals of critical groundwater in the Ararat Basin of Armenia. The USGS is working with partners, including USAID, to develop scientific tools for water-resource

Fitting a radio collar

Biologists with IGBST and the National Park Service fit a grizzly bear with a radio collar.  Once a bear is radio collared, biologists can track its movements with telemetry.

Grizzly released from trap

After the grizzly bear recovers fully from the anesthesia, it is released back into the wilderness.

Telemetry by air

Once a grizzly bear is radio collared, biologists can track its movements with telemetry via airplane.  The IGBST also used the latest telemetry technologies, which allows downloading of GPS data from the radio collar via satellites.

Culvert trap

Biologists place a culvert trap in locations that they need data from.  Field crews will set up the culvert trap and check it daily, usually in the morning, to determine if a bear has been captured.  Additionally, trap doors are checked via radio telemetry.

Telemetry by foot

Once a grizzly bear is radio collared, biologists can track its movements with telemetry on foot.

Culvert trap and bait

Biologists use road-killed ungulates such as deer, elk, or bison as bait in the traps.

At the capture site

At capture sites with road access, biologists drive to a trap with a bear inside to set up for collecting biological data.

An immobilized bear.

Biologists use a syringe pole to immobilize the captured grizzly bear.  It takes approximately 10 minutes for a bear to become immobilized.

Ready to remove from the trap

Biologists have immobilized the bear and prepare to lift it out of the trap and onto the tarp for data collection.  Once on the tarp the bear is easier to move.
