St. Petersburg Coastal and Marine Science Center
The U.S. Geological Survey (USGS) is conducting research on ocean acidification in polar, temperate, subtropical, and tropical regions including the Arctic, Gulf of Mexico and Florida estuaries, and the Caribbean and Pacific. Research strategies include new approaches for seawater chemistry observation and modeling, assessment of physiological effects on organisms, changes in marine ecosystem structure, new technologies, and information resources.

Arctic Research Cruises
The Arctic Research Cruises have produced new synoptic data from samples collected in the Arctic regions to provide insights into the patterns and extent of ocean acidification.
Polar Regions: The Arctic Ocean
The Arctic Ocean may be one of the world's oceans most vulnerable to climate change. With a fairly constant water temperature of 0°C, the Arctic has the ability to absorb carbon dioxide more readily than warmer waters. Ocean acidification may be occurring faster at the poles than other climate regions.
Temperate/Sub-tropical: The West Florida Shelf
Temperate and subtropical ocean regions are home to a diverse range of environmental conditions, habitats, species, and fisheries. Research is aimed at addressing data gaps in coastal waters and to increase understanding of how ocean acidification affects estuarine and shallow shelf marine waters.
Tropical Regions - Coral Reefs
The USGS is developing comprehensive records of modern and historical coral reef growth and calcification rates relative to changing seawater chemistry resulting from ocean acidification. These records will provide the foundation for predicting future impacts of ocean acidification and sea-level rise on coral reef growth.
