CTD data, R/V F. G. Walton Smith cruise WS1205 and WS1304, Mississippi Canyon, Gulf of Mexico, spring 2012 and 2013.

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 chemical and physical water column properties at various sampling sites in the Gulf of Mexico.

本研究于2012年和2013年分别实施两次科考航次，以持续监测微生物与浮游生物群落，同时评估颗粒通量速率、多环芳烃（PAHs）通过该过程从系统中去除的速率，以及多环芳烃在海底沉积物中的积累情况。本数据集涵盖墨西哥湾各采样点位的水柱化学与物理性质数据。
