Acidified waters are impacting commercial oyster
production in the U.S. Pacific Northwest, and favorable
carbonate chemistry conditions are predicted to become
less frequent. Within 48 h of fertilization, unshelled Pacific
oyster (Crassostrea gigas) larvae precipitate roughly 90% of
their body weight as calcium carbonate. We measured stable
carbon isotopes in...
Few studies to date have demonstrated widespread biological impacts of ocean
acidification (OA) under conditions currently found in the natural environment.
From a combined survey of physical and chemical water properties
and biological sampling along the Washington–Oregon–California coast in
August 2011, we show that large portions of the shelf waters...

In the mid-2000s the U.S. west coast oyster industry experienced several years of significant production failures. This industry has been referred to as the “canary in a coal mine” for ocean acidification (OA). Industry-led collaboration with university and government scientists identified a relationship between elevated carbon dioxide in seawater and...
Ocean acidification results in co-varying inorganic carbon system variables. Of these, an explicit focus on pH and organismal acid-base regulation in has failed to distinguish the mechanism of failure in highly sensitive bivalve larvae. With unique chemical manipulations of seawater we show definitively that larval bivalve shell development and growth...

Sustained time series have provided compelling evidence for progressive acidification of the
surface oceans through exchange with the growing atmospheric reservoir of carbon dioxide. However,
few long-term programs exist, and extrapolation of results from one site to larger oceanic expanses is
hampered by the lack of spatial coverage inherent to...

The undergradtuate research project was the completion, manipulation and assessment of a population model. The stage based population model assessed the late larval and juveniles stages of the hard shell clam Mercenaria mercenaria. There were seven class sizes input into the model starting with pediveligers and ending with juveniles at...
