Purpose:

The goal of this cruise is to evaluate the extent of fish disease and to characterize the distribution and fate of oiled sediment at sites on the continental shelf and slope of the northern Gulf of Mexico.

Data Parameters and Units:

Concentration of PAHs (2-6 ring polycyclic aromatic hydrocarbons), and biomarkers (hopanes, steranes, diasteranes) in sediment samples. All measurements are in ng/g, dry sediment: C12, C13, C14, C15, C16, C17, pristane, C18, phytane, C19, C20, C21, C22, C23, C24, C25, C26, C27, C28, C29, C30, C31, C32, C33, C34, C35, C36, C37, 17-alpha(H),21-beta (H)-hopane, Naphthalene, N1, N2, N3, N4, Acenaphthylene, Acenaphthene, Fluorene, Anthracene, Phenanthrene, P/AN1, P/AN2, P/AN3, P/AN4, Dibenzothiophene,D1,D2, Fluoranthene, Pyrene, FL/PY1, FL/PY2, FL/PY3, FL/PY4, Benz[a]anthracene, Chrysene, BAA/C1, BAA/C2, BAA/C3, BAA/C4, Benzo(b)fluoranthene, Benzo[k]fluoranthene, Benzo(a)pyrene, Perylene, Indeno[1,2,3-cd]pyrene, Dibenz(ah)anthracene, Benzo[ghi]perylene, BP/PER1, BP/PER2, BP/PER3, BP/PER4; Additional dataset attributes: Site (ID); Year (YYYY - December 2010, September 2011, August 2012, August 2013); Upper Interval (mm - section of sediment core sampled measured from sediment surface, where 0 mm = the top of the core); Lower interval (mm - lower interval = 10mm); The following is a list of stations and their coordinates: DSH07: 29.25°N, 87.74°W DSH08: 29.07°N, 87.52°W DSH10: 28.59°N, 87.53°W PCB06: 29.06°N, 87.16°W
