Abstract:
This dataset contains measurements and temporal assessment of polycyclic aromatic hydrocarbons (PAHs) in deep-sea shrimp species obtained aboard the R/V Point Sur PS23_04 (DP08, cruise https://doi.org/10.7284/909796) and PS23_22 (DP09, cruise https://doi.org/10.7284/910034) in the Gulf of Mexico from 2022-07-30 to 2023-05-08. Understanding the potential impact to the deep-pelagic habitat after the Deepwater Horizon oil spill is important due to their large abundance and role in the marine food web (as prey for shallow-living fish and marine mammal species). This dataset is a result of research funded by the National Oceanic and Atmospheric Administration's RESTORE Science Program (ROR - https://ror.org/0042xzm63) under award #NA19NOS4510193 to Nova Southeastern University.

Methods:
Samples were analyzed on an Agilent 7890B gas chromatograph 7010 triple quadrupole mass spectrometer. Injections (1 µl) into the multi-mode inlet in split-less mode were conducted. Inlet temperature held at 325°C. A 30m fused silica column (Rxi 5Sil MS with Integra-Guard, 30m x 0.25mm x 0.25μm, Cat# 13623-124, Restek, Bellafonte, PA, USA) was used with the following oven parameters: initial temperature 60°C, hold time 2 min; ramp 1 rate 8°C/min to 200°C, hold time 0 min; ramp 2 rate 4°C/min to 300°C, hold time 0 min, ramp 3 rate 10°C/min to 350°C, hold time 5 min. Helium was used for carrier flow at a rate of 1 ml/min and nitrogen gas was used for collision cell gas. The transfer line between the gas chromatograph oven and the mass spectrometer was held at 320°C, the ion source was held at 270°C, and both quadrupoles were held at 150°C. For accuracy and precision of sample sets, the instrument was tuned daily to PFTBA (perfluorotributylamine), and samples were checked with certified standards. Sample batches were re-analyzed when replicated standards exceeded ±20% of relative standard deviation (RSD), and/or when recoveries were low.
