PALMER - Wind damage early this winter rumpled the black, insulated plastic coverings over two Palmer Wastewater Treatment Plant lagoons and city workers say fixing the covers is not possible until the weather warms.

The covers, which cost $1.2 million and were........

......The covers and blowers have helped cut the city's ammonia levels in half, Berberich said by email. The city is investigating how to install another tool - an ammonia reactor, or large pad that gives bacteria a lot of surface area to break the ammonia down. It's not yet clear how much a reactor will cost or which type of reactor will be most useful for the city.

Meanwhile, Hulbert took another approach: is the ammonia hurting salmon? He and volunteers (mostly his family) have counted spawning salmon in the unnamed stream and three others nearby since 2008. They found the stream has a greater salmon escapement count than the popular fishing stream Wasilla Creek. Nearly 1/3 of all the salmon that return to the Matanuska River spawn in the tiny creek, Hulbert said.

Hulbert and his family also observed caged and free swimming salmon fry in the effluent mixing zone and elsewhere in the creek.

"Fry preferred the mixing zone and .....

Crabbers get a boost in bairdi Tanner quotas

LAINE WELCH Image via Wikipedia FISHERIES Published: November 7th, 2009 10:10 PM Last Modified: November 7th, 2009 10:12 PM KODIAK -- Kodiak and Alaska Peninsula crabbers got some good news last week -- bigger catch quotas for bairdi Tanner crab, a mid-January fishery important to local economies. Bairdi are the larger cousins of the better-known opilio Tanners, or snow crab. The bairdi boost stems from a big pulse of new crab recruits that biologists have been tracking for years. "That is what's fueling the increase in the harvest this year. We're just getting the very beginning of that year class," said.........

Danish commandos 'monitoring hippies' on Arctic offshore rig #artcticloons

Image by Steve Rhodes via Flickr Alaska Dispatch | May 31, 2011 Armed Danish commandos have (possibly) been summoned to monitor Earth-loving "hippies" clinging to the underbelly of an Arctic deepwater oil rig  off the coast of Greenland , sources say. The environmental non-governmental group  Greenpeace  has published  statements and  video  showing its activists aboard two ships that are attempting to "interfere" with oil exploration going on in the Davis Strait, 100 miles west of Greenland. This business has in turn prompted the Kingdom of Denmark to launch two ships and a few helicopters to monitor the Greenpeace interference. The  Leiv Eriksson  is the source of all this Arctic bait and switch. British oil company  Cairn Energy  is attempting to drill four wells at depths of at least 5,000 feet this summer in "iceberg-strewn sea" with the 53,000-ton offshore oil rig, which has made its way to Arctic waters after a month of failed attempts by Green
