Denali Fault: Sustina Glacier
Peter Haeussler examining the Denali fault trace on the Susitna Glacier to find matching ice surfaces to determine amount of fault offset....
Preparing Conductivity Temperature Depth Profiler (CTD)
Scientists are preparing the Conductivity Temperature Depth Profiler (CTD) before it is placed in the Arctic Ocean to collect data....
Conductivity Temperature Depth Profiler (CTD)
This is the top of the Conductivity Temperature Depth Profiler (CTD). When the instrument is lowered into the water and reaches a desired depth, an electronic signal is sent along these wires from the ship that closes the bottles and a water sample is collected. ...
Conductivity Temperature Depth Profiler (CTD)
U.S. Coast Guard member is preparing the Conductivity Temperature Depth Profiler (CTD) for deployment in the Arctic Ocean. The CTD collects water samples and measures conductivity and temperature as a function of water depth....
Conductivity Temperature Depth Profiler (CTD) in Arctic Ocean
The Conductivity Temperature Depth Profiler (CTD) is being lowered in the Arctic Ocean to collect water samples and measure conductivity and temperature as a function of water depth....

Water Samples from Conductivity Temperature Depth Profiler (CTD)
Robert Sanders, with Temple University, is collecting water samples from the CTD. Both Robert and Rebecca Gast, with Woods Hole Oceanographic Institution, were using the samples to study microorganisms in the Arctic Ocean....
Conductivity Temperature Depth Profiler (CTD)
These are the lids both on top and below the water bottles on the Conductivity Temperature Depth Profiler (CTD). When the CTD is placed in the ocean and reaches a desired depth, an electronic signal is sent from the ship that closes the bottles and a water sample is collected. ...

U.S. Coast Guard Cutter Healy
This is a view from the back of the U.S. Coast Guard Cutter Healy as it heads north in the Arctic Ocean....
Preparing Water-Quality Sampling Device for Use
A USGS scientist about the collect a water sample with a DH-95 sampler (the white torpedo looking device). After sampling, another scientist takes the bottle of water and pours it into the churn. Having another scientist do this prevents contamination of the sample....
Test Well, East River
USGS test well 10 34h363 in the East River, Brunswick, Ga. The U.S. Geological Survey drilled this test well in the early 1970's and at the time it was on the edge of the marsh at Andrews Island. It is now only accessible by boat or canoe at high tide. Despite being surrounded by saltwater the artes...
