Observations on the degradation of biogenic material in the deep ocean with implications on accuracy of sediment trap fluxes
The results of several observations and experiments indicate that the decay of organic material inside and outside of sediment traps in the deep ocean is on the order of 0.1-1.0% day−. These results must be considered when using sediment traps to determine the flux of organic material through the water column. The effectiveness of poisons in traps has not been adequately determined since the concentration of poisons in traps has not been monitored. Even traps containing poison may lose organic matter through leaching or from rapid grazing. A model is presented to quantify the loss of organic carbon at different decay rates and to determine optimum length of trap deployments.

More about this publication?
- The Journal of Marine Research, one of the oldest journals in American marine science, publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. Biological studies involving coupling between ecological and physical processes are preferred over those that report systematics. The editors strive always to serve authors and readers in the academic oceanographic community by publishing papers vital to the marine research in the long and rich tradition of the Sears Foundation for Marine Research. We welcome you to the Journal of Marine Research.
