NOAA: Launch of new biosensor picks up Heterosigma in Puget Sound

NOAA - 06-26-2012 - Until now, predictive tools to forecast dangerous algal blooms or pathogens that can contaminate shellfish in Puget Sound weren’t available. With the first launch of a novel biosensor—dubbed the ESP—in the Pacific Northwest in June 2012, NWFSC scientists are able to provide advanced warning of potentially dangerous outbreaks.
The biosensor, called the ESP (Environmental Sample Processor), is part of an integrated system that combines weather forecasts and an existing citizen monitoring network called SoundToxins. Advanced warning of toxic algal blooms or pathogens can help shellfish growers and public health officials better prepare for beach closures and mitigate economic impacts.
On June 8, NWFSC scientists and colleagues launched the ESP from the University of Washington’s Friday Harbor Laboratories. Within a short time, scientists got a hit forHeterosigma, a fish-killing algae in Puget Sound and one of the target organisms for this deployment. Scientists also detected Alexandrium and Pseudo-nitzschia pseudodelicatissima, other toxic algal species, but more information is needed to calculate their concentrations in Puget Sound.
Scientists have programmed the ESP to sample waters each day at 10 am until July 22. Stay tuned on this project and more on our Facebook page, NOAA Fisheries in the Northwest.
Learn more about the ESP by checking out our fact sheet and YouTube video. The ESP was purchased with funding from NOAA’s Oceans and Human Health Initiative, and was first developed by microbiologist Chris Scholin and his team at the Monterey Bay Aquarium Research Institute.

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......... http://www.adn.com/money/welch/story/1004091.html

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
