Enhanced rates of particulate organic matter remineralization by microzooplankton are diminished by added ballast minerals [PDF]

open access: yesBiogeosciences, 2013
To examine the potentially competing influences of microzooplankton and calcite mineral ballast on organic matter remineralization, we incubated diatoms in darkness in rolling tanks with and without added calcite minerals (coccoliths) and ...

Nutrient utilisation and particulate organic matter changes during summer in the upper mixed layer (Ross Sea, Antarctica). [PDF]

open access: yes, 1997
peer reviewedThe relationships among vertical stability, estimated nutrient utilisation and particulate organic matter in the Ross Sea are analysed from data collected during two cruises in the summers of 1987 - 88 and 1989 - 90. In the upper mixed layer

Sedimentation of particulate matter in the south-west lagoon of New Caledonia : spatial and temporal patterns [PDF]

open access: yes, 1995
Suspended and sedimented particulate materials were assessed monthly at five sites on the south-west lagoon of New Caledonia, from May 1986 to April 1987. Sedimentation of particulate matter was measured using sediment traps for 24 h. Resuspension, which

THE USE OF C/N RATIO IN ASSESSING THE INFLUENCE OF LAND-BASED MATERIAL IN COASTAL WATER OF SOUTH SULAWESI AND SPERMONDE ARCHIPELAGO, INDONESIA

open access: yesFrontiers in Marine Science, 2016
Measurement of C-N magnitude and C/N ratio from particulate matter is used to explain the source of terrestrial and sea particulates. Therefore, this study aimed at using C/N ratio in assessing land-based material in the west coast of Spermonde area ...
