The Laboratory for Microbial Oceanography is a research unit within the School of Ocean and Earth Science and Technology at the University of Hawaii at Manoa. The Laboratory for Microbial Oceanography conducts basic research on microbial inhabitants of the sea, including bacteria, protozoans and unicellular algae. These studies range in scope from the development of novel techniques to assess in situ microbial biomass, activity and growth, to comprehensive field studies designed to elucidate the mechanisms and rates of microbiological cycling of C, N and P.

Indicator Specification
Archived
Ocean acidification This indicator illustrates the global mean average rate of ocean acidification, quantified by decreases in pH, which is a measure of acidity and is defined here as the hydrogen ion concentration. A decrease in pH value corresponds to an increase in acidity. The observed decrease in ocean pH resulting from increasing concentrations of CO 2 is an important indicator of global change. This indicator provides information on: - trends in ocean acidity measured at the Aloha station; - yearly mean surface sea water pH levels reported on a global scale, based on information from the Copernicus Marine Service (CMEMS), with the estimated long-term decreasing trend.
