Description

Sediment trap flux data collected on the Trophic BATS cruises in the Sargasso Sea. Data are from 4 cruises over the span 2011-2012.

Acquisition Description

Samples for particles flux measurements were obtained using free-drifting cylindrical traps (MultiPITs) deployed at 150, 200, and 300 meters depth. Sinking fluxes of C, N, and P were calculated from the elemental mass of material captured in the sediment trap, its collection surface area and deployment length. Detailed methods for all data collected as part of this study can be found in the publications arising from this study (references given below).

Sample QA/QC procedures followed those given in the associated manuscripts. Sample accuracy was assessed by using certified standards, for those measurements where standards are available. Certified standards were run with each analytical run and compared to long term control charts for respective analyses.

Processing Description

Data that were either not collected or were found to be in error for other reasons are denoted by 'nd'. Most of the data given in this dataset are not derived variables and are calculated using reasonably standard equations as given in the appropriate references. Where data are derived (e.g., bacterial carbon biomass) the appropriate reference is given in the parameter definition.

BCO-DMO Processing Notes:
- Modified parameter names to conform with BCO-DMO naming conventions.
- Replaced '-9.99' with 'nd'.

Instruments

Sediment Trap - Particle Interceptor

Supplied Description:

Instrument Type

Generic Name: Sediment Trap - Particle Interceptor

Acronym: Sed Trap - Part Int

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

Generic Description:

A Particle Interceptor Trap is a prototype sediment trap designed in the mid 1990s to segregate 'swimmers' from sinking particulate material sampled from the water column. The prototype trap used 'segregation plates' to deflect and segregate 'swimmers' while a series of funnels collected sinking particles in a chamber (see Dennis A. Hansell and Jan A. Newton. September 1994. Design and Evaluation of a "Swimmer"-Segregating Particle Interceptor Trap, Limnology and Oceanography, Vol. 39, No. 6, pp. 1487-1495).
