Sea Change: The ocean is growing more acidic, changing the behavior of fish and dissolving creatures on the bottom of the food chain. Read more about ocean acidification. See photos from the Times’ coverage of the issue from Papua New Guinea and the Bering Sea. Watch the documentary videos on how ocean acidification could alter the seas on a scale too big to fathom.
Seahawks: Yes, it’s week 2 — but this is a big one. The 49ers are back in town after last year’s 42-13 drubbing on CenturyLink Field and looking for revenge. Drenching rain, 30 mph winds and even thunderstorms could hit during the game. Bob Condotta breaks down the keys to the game and what to watch for this time around.
Huskies beat Illinois: With their high-flying offense, the 19th-ranked Huskies prevailed on Soldier Field over Illinois. The Dawgs racked up 615 yards of total offense, but also tallied 12 penalties and plenty of other little mistakes. Although they were expected to win, the Huskies impressive offensive performance bumped them up in the Associated Press rankings this morning to 17th.
Stabbing after soccer match: Yesterday, a Shoreline Community College professor died after he was stabbed while leaving a Seattle Sounders game on Friday night in a seemingly random and unprovoked attack. His 30-year-old partner was in serious condition as of Saturday afternoon. The alleged attacker, a 44-year-old man is now in King County Jail. He was arrested on investigation of murder.

Weather: Not so bad, really. Dry today, highs in the upper 40s. Patchy fog this morning. The forecast.
Worrisome environmental news: New research by Seattle scientists concludes that ocean acidification is causing damage decades earlier than expected. The finding has sweeping implications for the marine food chain. Read the account by Craig Welch, our environment reporter.
Marijuana entrepreneurs — going from black market to legitimacy? The (Tacoma) News Tribune looks at the business opportunities some are hoping for following the vote this month to legalize recreational use of marijuana. From the TNT: ”(Jeff) Gilmore, 59, a longtime Thurston County resident, said he’s been growing and selling pot since shortly after he graduated from the University of Washington back in the Vietnam War era… Gilmore is one of an army of black-market pot purveyors who, with the passage of Initiative 502 legalizing up to an ounce of pot for all adults, hope to make lateral transfers into the legitimate market.” Read the full story.
The Seahawks: Bad news followed by worse news? Sunday’s loss to Miami — showcasing a defensive collapse — was followed by a report by ESPN that Brandon Browner and Richard Sherman might face four-game suspensions for violating league policy on performance-enhancing substances. The players plan to appeal, according to the report. Reporter Danny O’Neil writes about the meltdown in Miami and the news of the possible suspensions.

Researchers for the first time have found definitive evidence that changing ocean chemistry from increased carbon-dioxide emissions are at least partially responsible for massive oyster die-offs in the Pacific Northwest.
The research published Wednesday by scientists from Seattle and Oregon State University is the first anywhere to show that increasingly corrosive seas already are killing marine organisms in North America.
“This is the smoking gun for oyster larvae,” said Richard Feely, an oceanographer and leading marine-chemistry researcher with the National Oceanic and Atmospheric Administration in Seattle and one of the paper’s authors. “This is the clearest experimental evidence yet that lower pH is making oysters die.”
Said Alan Barton, another of the paper’s authors, “It’s now an incontrovertible fact that ocean chemistry is affecting our larvae.”
Since 2005, wild oysters along the Washington coast and oysters at a commercial shellfish hatchery in Oregon have been dying by the billions. Leading scientists long have suspected that one of the causes is the increasing corrosiveness of ocean waters that frequently rise up from the deep during high winds to lap against the shore.
Scientists long have predicted that as carbon dioxide from greenhouse gas emissions get taken up by the seas, the chemistry of ocean waters would slide toward the acidic side of the pH scale. Feely and other researchers in 2007 and 2008 were among the first to show that ocean pH along the West Coast already had dropped more than had been expected for decades.
But it was always possible that the waters hitting the oyster-rich shores of Willapa Bay or being drawn into seaside hatcheries was either too warm or carrying bacteria or other pollutants that were killing oysters before they had a chance to form their shells.
But in their new paper published in the journal Limnology and Oceanography, researchers were able to control for temperature and bacteria and other factors.
When ocean water lower in pH got sucked directly into the Whiskey Creek Shellfish Hatchery in Netarts Bay, Ore., the oysters died. When the pH was higher, oysters survived just fine.
“This is not just some lab experiment,” Barton said. “This is real ocean water – from today, not from some predicted future — impacting shell formation. It’s a pretty important finding.”
