Research Description
James Bishop is a professor of Marine Science in the Department of Earth and Planetary Science. At sea, his research group's main focus is to understand and thus gain predictive capability of how biological processes operate to transform and transport carbon in the sea. The very fast and dynamic carbon flows in the ocean, which govern atmospheric CO2, are substantial and there are open questions regarding the stability of these flows due to human induced warming and acidification of the ocean. Is the ocean biological carbon pump strengthening (good) or weakening (bad)? We just don't know. We need to find out. Given that photosynthetic organisms in the ocean live for a week, observations using ships have been limited. This is what motivates our development of autonomous ocean carbon observing sensors and robots. Our latest robot, the "Ocean Carbon Observer", will follow daily variations of particulate organic and inorganic carbon concentrations and fluxes to kilometer depths during missions lasting from seasons to years in the remote ocean. On land, we have applied ocean robotic methodology to enable high frequency observations of the chemistry of water as it transits the forest canopy and the unsaturated soils and fractured bedrock to form ground water on its way to the ocean.
