Dissolved organic carbon leaching from plastics stimulates microbial activity in the ocean
Nature Communications, 2018 Approximately 5.25 trillion plastic pieces are floating at the sea surface. The impact of plastic pollution on the lowest trophic levels of the food web, however, remains unknown. Here we show that plastics release dissolved organic carbon (DOC) into the

Short term effects of exposition to artificial ultraviolet radiation on Parabroteas sarsi (Copepoda, Calanoida) [PDF]
, 2012 The increase in the penetration of ultraviolet radiation that has been reported lately for freshwater ecosystems in southern South America would allegedly generate alterations in ecological processes. In this respect the mortality of Parabroteas sarsi, a

The Nature of Carbon Flux in Gunungsewu Karst, Java-Indonesia
Acta Carsologica, 2016 The research documented here aims to clarify the transport and fate of carbon species that evolved in a typical conical karst system in Gunungsewu. Special interest is attributed to the estimate of carbon flux by considering the conical karst as a whole ...

Net community production in the North Atlantic Ocean derived from Volunteer Observing Ship data [PDF]
, 2014 The magnitude of marine plankton net community production (NCP) is indicative of both the biologically driven exchange of carbon dioxide between the atmosphere and the surface ocean and the export of organic carbon from the surface ocean to the ocean ...

Sunlight Converts Polystyrene to Carbon Dioxide and Dissolved Organic Carbon
Environmental Science and Technology Letters, 2019 Numerous international governmental agencies that steer policy assume that polystyrene persists in the environment for millennia. Here, we show that polystyrene is completely photochemically oxidized to carbon dioxide and partially photochemically ...
