From: Ocean News Weekly/ By: Ocean Leadership Staff What Passed Many appropriations bills moved last month, including the Senate’s Commerce-Justice-Science bill, which was approved by both the committee and subcommittee. So far, the full appropriations committees have approved all 12 bills in the Senate and 10 in the House. A minibus that includes the [...]
Dr. John Lehrter recently wrapped up research expedition number two of 2018. Both delivering different samples to analyze, but all in a quest to answer the larger question. How does the ocean work? (From Dauphin Island Sea Lab) -- “It’s like being invited to another lab,” Dr. Lehrter said. “ There’s a great deal of [...]
(Credit: Hannah Barkley, Woods Hole Oceanographic Institution) The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study identifies the details of how ocean acidification affects coral skeletons, allowing scientists to predict more precisely where corals will be more vulnerable. (From [...]
(Credit: British Antarctic Survey) A new study of tiny marine snails called sea butterflies shows the great lengths these animals go to repair damage caused by ocean acidification. The paper, led by researchers at British Antarctic Survey, is published this month in the journal Nature Communications. (From Phys.org) --The ocean absorbs around one [...]
(Credit: Sophie McCoy/ FSU) California mussels aren't built like they used to be. According to new research, increasing ocean acidification is altering the structural makeup of mussel shells along the West Coast. (From UPI.com/ By Brooks Hays) -- Traditionally, long, cylindrical calcite crystals for neat and predictable rows in the shells of [...]
Melting glaciers might be making ocean water more acidic, an unexpected finding that's given scientists new cause for concern. A new study published yesterday in the journal Nature Climate Change suggests surprising ways that climate change is drastically altering the water chemistry in deep seas—a process that may happen faster than researchers anticipated.
Australian scientists are optimistic that a fertility treatment for coral could help regenerate the Great Barrier Reef. The 2,300 kilometer long coral reef -- a UNESCO World Heritage Site -- has been extensively damaged by a process known as coral bleaching in which warm water stresses the organism and causes it to die.

The Chukchi Ecosystem Observatory is maintained by a multi-institutional, multi-investigator partnership that includes the University of Alaska Fairbanks, the Alaska Ocean Observing System, the North Pacific Research Board, Olgoonik-Fairweather, Université Laval, and the University of Washington. On a recent research mission, University of Alaska Fairbanks scientists brought home the first [...]
The effects of ocean acidification on marine life have only become widely recognized in the past decade. Now researchers are rapidly expanding the scope of investigations into what falling pH means for ocean ecosystems. The ocean is becoming increasingly acidic as climate change accelerates and scientists are ramping up investigations into the impact on marine life and ecosystems. In just a few years, the young field of ocean acidification research has expanded rapidly – progressing from short-term experiments on single species to complex, long-term studies that encompass interactions across interdependent species.
The Senate Oceans Caucus and U.S. Integrated Ocean Observing System Association hosted a briefing on Thursday to address advances in ocean observing and technology that are important to national security, the economy, and environmental health.
Scientists at Caltech and USC have discovered a way to speed up the slow part of the chemical reaction that ultimately helps Earth to safely lock away, or sequester, carbon dioxide into the ocean. Simply adding a common enzyme to the mix, the researchers have found, can make that rate-limiting part of the process go 500 times faster. A paper about the work appears online the week of July 17 ahead of publication in the Proceedings of the National Academy of Sciences.
University of Adelaide researchers have for the first time demonstrated that the ocean acidification expected in the future will reduce fish diversity significantly, with small 'weedy' species dominating marine environments. Published today in Current Biology, the researchers studied species interactions in natural marine environments at underwater volcanic vents, where concentrations of CO2 match those predicted for oceans at the end of the century. They were compared with adjacent marine environments with current CO2 levels.
