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.

Figure Decline in ocean pH measured at the Aloha station and yearly mean surface seawater pH reported on a global scale (Copernicus Marine Service) The figure shows a decline in pH corresponds to an increase in the acidity of ocean water and the global annual average of surface ocean pH from the Copernicus Marine Service, based on a reconstruction method using in situ data and remote sensing data, as well as empirical relationships.

Decline in ocean pH measured at the Aloha station and yearly mean surface seawater pH reported on a global scale (Copernicus Marine) A decline in pH corresponds to an increase in the acidity of ocean water. - Green line: data based on in situ measurements at Aloha station. - Blue line: pH calculated at Aloha station from dissolved inorganic carbon concentrations and total alkalinity, at in situ temperature. - Red line: global yearly mean surface seawater pH, calculated by Copernicus Marine Environment Monitoring Service.
