(2004) obtained data that showed the C:N ratio of the particulate organic matter (POM), collected from a sediment trap
in the Soledad Basin, ranged from 8 to 12.
Vortsjarv, and as the sediment trap
experiments have shown, the major part (up to 96%) of the downward particle flux (including PhPs) is formed of resuspended material (Noges et al.
5: Suspended-sediment concentrations (g/L) in irrigation tailwater at the sediment trap
inlet and outlet.
Their topics include photosynthetic pigment concentrations in marine sediments, total protein flux from sediment trap
samples, abundance of metazoan meiofauna, benthic bacterial diversity based on cloning and sequencing 16S rRNA genes, and organic carbon remineralization rates in marine surface sediments.
It was also good to see some attention paid to sediment control, as a sediment trap
was used to minimize impacts during the construction process and keep sediment from leaving the site.

The sediment trap
samples indicated that the subsequent rapid gonadal growth coincided with increased food availability.
Providing a sediment trap
outside the navigation channel or harbor area is sometimes feasible under certain specific natural conditions.
While forest buffers can to some degree mimic the role once played by the watershed's vast forests, they can never replace the massive nutrient sponge and sediment trap
of past forests.
NFPA [sections] 5.5.6 requires that a sediment trap
or drip leg be installed on all gas systems that run uphill or "upstream" to the automatic controls, such as on a furnace or water heater.
