Abstract:

This dataset has CTD and positional data from sediment grabs taken on the NOAA ship Pisces (2013) and Gordon Gunter (2014). Two shoreline collections from Louisiana and Alabama are included in the 2014 data. All sediment grabs on the NOAA cruises were made with a multicorer, unless a Shipek (R) grab is indicated. Samples from the multicorer tubes or the Shipek grab were subsampled to a depth of 5 cm. The two shoreline collections were taken to a depth of 25cm (Slidell Louisiana, shovel collection) or to a depth of 5cm (Dauphin Island, hand core). Sediment samples were sent to the Louisiana State University Ag center, where trace metals determination was made using EPA method 200.7.

Purpose:

To determine trace metals concentrations along the continental shelf in the Gulf of Mexico.

Data Parameters and Units:

Trace metals concentrations are in mg/kg. The final values for each sediment site are in the column entitled "blank-corrected sample conc" The sample field IDs are listed in column two, and correspond to the station number on the NOAA CTD data page. For example- Sample field ID 134-5 on the trace metals data page corresponds to station 134 on the NOAA CTD data page. 134 Shipek on the metals page corresponds to station 134 Shipek on the NOAA CTD data page.
