Russian officials say warming permafrost could be linked to a deadly anthrax outbreak in Siberia this month. Permafrost can be found almost everywhere in Alaska — from the Arctic coast to Anchorage. But at least one expert isn’t alarmed about the potential for thawing ground to bring old diseases back to life.

While trawling the floor of the Bering Sea and the Aleutian region, scientists have discovered several new species of fish -- snailfish. Some were only named last year. Researchers were not looking for them, the trawl was a part of a yearly stock assessment by the federal government that helps set quotas for fisheries.

After combing through data from the Aleutian Islands, a scientist has discovered an unexpected relationship between plankton and pink salmon. Although plankton might seem like an ecological afterthought, biological oceanographer Sonia Batten disagrees. She calls them the most important organisms in the ocean.

“They’re the basis of every marine food chain pretty much,” said Batten. “They support directly, or indirectly, the resources that we value.”

Unalaskans are worried about the sockeye salmon run at Front Beach — thanks to a growing number of nets and seemingly fewer fish.

That's why the Unalaska/Dutch Harbor Fish and Game Advisory Committee has proposed a new regulation aimed at conserving reds.

"Our motion is to submit an agenda change request to limit the number of sockeye taken from Front Beach with subsistence gear to no more than 10 per permit holder," said Secretary Jennifer Shockley at Tuesday's committee meeting.

Using Seismic Waves to Map Okmok Volcano

In the rich volcanic landscape of the Aleutian Islands, Okmok volcano on Umnak Island has drawn special attention this summer. Matt Haney, a research geophysicist with the Alaska Volcano Observatory, is part of a team trying to create an image of the inside of Okmok. The process is like a geological CAT scan, mapping the earth rather than the body.

Last summer, the team set out an array of seismometers – sensors that pick up the same seismic waves that characterize earthquakes – on and around the volcano.
