Description:

Abstract:

Time-series of sediment chemistry, including organic biomarker composition and bulk inorganic geochemical analytes, from samples collected over a one-year period in a sediment trap. The sediment traps were deployed at a depth between 603 m to 1318 m, and they were programmed to rotate a 250 mL sample bottle at 30 d intervals, delivering 12 samples during the 1-year deployment between August 2012 and June 2013. In addition, dissolved water column nutrient concentrations and water column trace element particulate concentrations were collected in Baltimore Canyon on the U.S. Mid-Atlantic Bight (MAB).

Purpose:

These samples were collected and analyzed to characterize the temporal variability in source, transport, and fate of particulate matter in Baltimore Canyon.

Process_Description:

Edited metadata and header columns of csv data file to correct a typo that resulted from an encoding vs plain text problem. The data file read 5-_-coprostanone, which should be 5-β-coprostanone, and _-sitosterol, which should be β-sitosterol. The Attribute information in the metadata was corrected, as well using static point of contact information to bring it up to PCMSC standards. No data values were changed.
