Abstract:

Two research cruises, one in 2012 and one in 2013, were conducted to continue to monitor the microbial and planktonic communities and to assess rates of particle flux and the rates of removal of PAHs from the system via this process and accumulation of PAHs in bottom sediments. This dataset includes underway data collected aboard the R/V F. G. Walton Smith during the April 2012 cruise in the Gulf of Mexico.
