For the fourth year in a row, weekly summer water quality tests show that most Ketchikan beaches have elevated levels of bacteria that could make people sick. That happened this year even without dozens of cruise ships sailing through the Inside Passage and discharging wastewater.

Scientists are on the lookout for an invasive crab species expected to move north into Alaskan waters. This year in Southeast Alaska, they added a new tool to the monitoring effort for European green crab, a threat to the state’s shellfish and salmon.
European green crab or shore crab have been expanding their range north along the Pacific coast. But this year they were discovered just south of the Alaskan border.
“This Haida Gwaii occurrence last summer puts them very close to us and I really wish I could say we don’t expect them but prudence dictates that we say yes we think it’s a matter of when, not if,” said Linda Shaw, invasive species coordinator for the Alaska regional office of NOAA Fisheries.
