Abstract:

Raw data of a moored sediment trap deployed in the Northern Gulf of Mexico as part of a long-term time series to understand particle flux dynamics. Samples were collected from June 2013 to April 2014.

Purpose:

Time series data of sedimentation rates in the Northern Gulf of Mexico. These are the raw analytical data for all cups of this deployment, covering roughly one year. Fluxes can be calculated from the available data. Other deployments from this time series are saved as separate files.

(2017). Supernatant water was analyzed as followed: Concentrations of NO3+NO2, PO4 and Si(OH)4 in the water overlaying the solid material were measured by simultaneous flow injection analysis (QuickCem 8000, Lachat Instruments). The pH (total scale) was measured with a spectrophotometer (Genesys 10SVIS) equipped with a single cell Peltier (SPG1A, both Thermo Scientific) using the indicator dye m-cresol purple (Sigma-Aldrich) at a constant temperature of 25ºC. The absorbance was measured at 730 nm, 578 nm, and 434 nm before and after dye addition (Clayton, 1993; Fangue, 2010). To calculate fluxes of a specific component x, use the formula: Flux=average(x/Split_fraction)/Deployment_time/Trap_Area|Sediment trap: Kiel Trap, K.U.M.
