Barb Block, salmon-shark tagging in Alaska. Our last day in Gravina Bay on Friday was spectacular. Every vista was different: Snow peaks and fir trees. Velvety green meadows. In all directions, trees with eagles roosting. We began the day with some quick catches and successful tagging. We were able to put out 4 tags before the weather came in with winds that made drifting a bit tricky. We ended the day with 18 successful tagging events, most sharks with multiple tags.

Barb Block, salmon-tagging in Alaska. Well, yesterday was not the day we shark taggers dream of. It was the day that reminds me why few have done this work before.

Barb Block, salmon-tagging in Alaska. Today in Prince William sound was perfect. I was in the work skiff much of the day.

Who'da thunk that a shark could be warm-bodied, but salmon sharks are.

Most salmon sharks head south and roam the warm waters offshore of Hawaii, California and Mexico until the spring, when they begin their journeys back to Prince William Sound.
