| Zusammenfassung |
| The California Current Large Marine Ecosystem (CCLME), a temperate marine
region dominated by episodic upwelling, is predicted to experience rapid
environmental change in the future due to ocean acidification. The aragonite
saturation state within the California Current System is predicted to
decrease in the future with near-permanent undersaturation conditions
expected by the year 2050. Thus, the CCLME is a critical region to study due
to the rapid rate of environmental change that resident organisms will
experience and because of the economic and societal value of this coastal
region. Recent efforts by a research consortium – the Ocean Margin
Ecosystems Group for Acidification Studies (OMEGAS) – has begun to
characterize a portion of the CCLME; both describing the spatial mosaic of pH
in coastal waters and examining the responses of key calcification-dependent
benthic marine organisms to natural variation in pH and to changes in
carbonate chemistry that are expected in the coming decades. In this review,
we present the OMEGAS strategy of co-locating sensors and oceanographic
observations with biological studies on benthic marine invertebrates,
specifically measurements of functional traits such as calcification-related
processes and genetic variation in populations that are locally adapted to
conditions in a particular region of the coast. Highlighted in this
contribution are (1) the OMEGAS sensor network that spans the west coast of
the US from central Oregon to southern California, (2) initial findings of
the carbonate chemistry amongst the OMEGAS study sites, and (3) an overview of
the biological data that describes the acclimatization and the adaptation
capacity of key benthic marine invertebrates within the CCLME. |
