BCO-DMO Edits

- parameter names modified to conform to BCO-DMO convention

- Blank rows in original sheet removed

- 'nd' added to blank cells

- Made column header record one line

- Deleted SampleId and Depth columns (both were blank)

BCO-DMO Note:

Station_Id does not conform to any other SOIREE sediment trap stations convention.

Instrument Type

Generic Name: Sediment Trap

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/33/

Generic Description:

Sediment traps are specially designed containers deployed in the water column for periods of time to collect particles from the water column falling toward the sea floor. In general a sediment trap has a jar at the bottom to collect the sample and a broad funnel-shaped opening at the top with baffles to keep out very large objects and help prevent the funnel from clogging. This designation is used when the specific type of sediment trap was not specified by the contributing investigator.
