Workshop on the Impacts of Increasing Atmospheric CO2 on Coral Reefs and Other Marine Calcifiers

18-20 April 2005
USGS Center for Coastal and Watershed Studies
St. Petersburg, Florida

Calcification rates of several major groups of marine calcifying organisms, from both neritic and pelagic environments, will very likely decrease in response to changes in ocean carbonate chemistry. Although benthic and planktonic calcifiers of both neritic and pelagic communities display a similar response to increased CO2 forcing, important differences exist between the two that will dictate different approaches toward assessing the larger potential effects of reduced calcification on ecosystem structure and function, how the effects could cascade to other ecosystems, and ultimately, the changes in the ocean carbon cycle. This 3-day workshop was designed to:

1. identify the similarities and differences between neritic and pelagic calcifying ecosystems; delineate the most important hypotheses within the overall question of “What are the ecological consequences of increasing atmospheric CO2 on marine calcifying communities?”;

2. exchange ideas and technical advancements to maximize our ability to design efficient research studies in these environments;

3. discuss options for future study in the respective environments; e.g.:

a. what information can be gained from natural temporal and spatial variation
b. where can we take advantage of existing observing systems, and with what technology, for both monitoring and experimental testing of hypotheses
c. what scientific hypotheses will require testing with experimental manipulations

4. provide guidance on moving forward in research and monitoring (prioritizing needs, recommending partnerships, capitalizing on existing efforts).
