Photodissolution and other photochemical changes upon irradiation of algal detritus
Several recent lines of literature point toward strong photoreactivity of phytoplanktonic detritus. We examined effects of irradiation of algal membrane fragments in various stages of decay, withExpand

Photooxidation of particulate organic matter, carbon/oxygen stoichiometry, and related photoreactions
Abstract We investigated photoredox transformations of oxygen, carbon, peroxides, and iron that accompany “photodissolution” of suspended marine particulate organic carbon (POC), a sunlight-inducedExpand

Role of Iron and Organic Carbon in Mass-specific Light Absorption by Particulate Matter from Louisiana Coastal Waters
We investigated the influences of organic content and mineralogical composition on light absorption by mostly mineral suspended particles in aquatic and coastal marine systems. Mass-specificExpand

Observations of carbon export by small sinking particles in the upper mesopelagic
Abstract Carbon and nutrients are transported out of the surface ocean and sequestered at depth by sinking particles. Sinking particle sizes span many orders of magnitude and the relative influenceExpand

Rate and apparent quantum yield of photodissolution of sedimentary organic matter
We quantified rates of photochemical dissolution (photodissolution) of organic carbon in coastal Louisiana suspended sediments, conducting experiments under well-defined conditions of irradiance andExpand

Decoupling of net community and export production on submesoscales in the Sargasso Sea
Determinations of the net community production (NCP) in the upper ocean and the particle export production (EP) should balance over long time and large spatial scales. However, recent modelingExpand

Autonomous, high-resolution observations of particle flux in the oligotrophic ocean
Observational gaps limit our understanding of particle flux attenuation through the upper mesopelagic because available measurements (sediment traps and radiochemical tracers) have limited temporalExpand

Particle dynamics in the rising plume at Piccard Hydrothermal Field, Mid‐Cayman Rise
Processes active in rising hydrothermal plumes, such as precipitation, particle aggregation, and biological growth, affect particle size distributions and can exert important influences on theExpand
