EDF chief hedges on key ’08 report

By Richard Gaines | Staff Writer

Doug Rader, chief ocean scientist at Environmental Defense Fund, conceded Monday his organization’s 2008 policy paper predicting a jellyfish-dominated oceanic catastrophe oversimplified the problem.

“Oceans of Abundance,” which was underwritten by the Walton Family Foundation and co-authored by NOAA Administrator Jane Lubchenco, then an EDF official, foresaw “the collapse of global fisheries in our lifetimes,” to be replaced by “massive swarms of jellyfish” — unless the wild stocks were immediately privatized and commodified for “catch share” trading in the global investment market.

EDF’s Rader was responding to a Monday Times story about the publication in the February issue of BioScience on research that found no evidence of a trend toward an explosion of the jellyfish — or “gelatinous zooplankton” — filling the void left by the removal of more complex fishes.

The team was headed by ecologist Robert Condon of the Dauphin Island Sea in Alabama and 17 other scientists.

Abundant Sacramento and Klamath Salmon Drive Season Options

Written By Dan Bacher 

In the Klamath River, biologists are forecasting four times more salmon than last year – and an astounding 15 times more than in 2006, according to the PFMC. The ocean salmon population is estimated to be 1.6 million adult Klamath River fall Chinook, compared to last year’s forecast of 371,100.

The Pacific Fishery Management Council (PFMC) at its meeting in Sacramento on March 7, encouraged by predictions of plentiful salmon returns along the West Coast, released three alternatives for ocean salmon fisheries including those based on Sacramento River and Klamath River stocks.

In all three alternatives, the recreational ocean salmon season is slated to open on April 7 in the Fort Bragg, San Francisco and Monterey areas, from Horse Mountain to the U.S./Mexico Border. There are three opening date alternatives – May 1, May 12 and May 26 – for the Oregon and California Klamath Management Zones.

After hearing public comment on the alternatives, the Council will make a final recommendation at their next meeting in Seattle on April 1-6.

Oceans’ acidic shift may be fastest in 300 million years

The world’s oceans are turning acidic at what could be the fastest pace of any time in the past 300 million years, even more rapidly than during a monster emission of planet-warming carbon 56 million years ago, scientists said on Thursday.

Looking back at that bygone warm period in Earth’s history could offer help in forecasting the impact of human-spurred climate change, researchers said of a review of hundreds of studies of ancient climate records published in the journal Science.

Quickly acidifying seawater eats away at coral reefs, which provide habitat for other animals and plants, and makes it harder for mussels and oysters to form protective shells. It can also interfere with small organisms that feed commercial fish like salmon.

The phenomenon has been a top concern of Jane Lubchenco, the head of the U.S. National Oceanic and Atmospheric Administration, who has conducted demonstrations about acidification during hearings in the U.S. Congress.

Oceans get more acidic when more carbon gets into the atmosphere. In pre-industrial times, that occurred periodically in natural pulses of carbon that also pushed up global temperatures, the scientists wrote.

Human activities, including the burning of fossil fuels, have increased the level of atmospheric carbon to 392 parts per million from about 280 parts per million at the start of the industrial revolution. Carbon dioxide is one of several heat-trapping gases that contribute to global warming.
