Reconciling measured and predicted fluxes of oxygen across the deep sea sediment-water interface

Creator:: Reimers, Clare E. and Smith, K. L., Jr.
Abstract:: Rates of sediment community oxygen consumption determined in situ are compared to fluxes predicted from oxygen microelectrode gradients measured in cores from ~3,750-m water depth in the eastern North Pacific. Oxygen concentrations decrease exponentially over > 1.5 cm and suggest that organic matter in the sediments is degraded most rapidly...

The development of pH and pCO2 microelectrodes for studying the carbonate chemistry of pore waters near the sediment-water interface

Creator:: Cai, Wei-Jun and Reimers, Clare E.
Abstract:: We made stable and rapid-responding pH and pCO2 microelectrodes. The pH microelectrode has a ~100-μm-diameter half-sphere bulb tip of pH glass, and the pCO2 sensor has a 200–300-μm-diameter silicone-membrane covered tip. Because the pH microelectrodes have electrical resistances that arc > 1O[to the tenth] ohms, all electrical connections are kept...

Dissolved inorganic carbon profiles and fluxes determined using pH and PCO2 microelectrodes

Creator:: Komada, Tomoko, Reimers, Clare E., and Boehme, Susan E.
Abstract:: Submillimeter depth distributions of total dissolved inorganic carbon (DIC) were derived from pH and PCO2 profiles measured with microelectrodes in an organic-rich, laboratory-maintained sediment. The DTC profiles were used to calculate diffusive fluxes of DIC across the sediment-water interface. In two experiments, the calculated diffusive fluxes fell within ±50% of...

Seasonal spillover and varve formation in the Santa Barbara Basin, California

Creator:: Reimers, Clare E., Lange, Carina B., Tabak, Marialana, and Bernhard, Joan M.
Abstract:: A temporal record of oxygen and NO3- concentrations in the bottom water of the Santa Barbara Basin indicates that outside waters spill over into the basin seasonally. It is proposed that an annual bottom-water cycle leads ultimately to varve production. As evidence in support of a benthic mechanism for varve...

Microelectrode Velocity Effects and Aquatic Eddy Covariance Measurements under Waves

Creator:: Reimers, Clare E., Özkan-Haller, H. Tuba, Albright, Andrea T., and Berg, Peter
Abstract:: Interest in validating the eddy covariance (EC) technique under wave-induced flows led to a series of experiments in a 104-m-long large wave flume (LWF) using an acoustic Doppler velocimeter (ADV) and two oxygen microelectrodes (tips ~2 mm apart) mounted on a sturdy tripod. Four additional ADVs positioned within the flume...
