Abstract:

Sampling of in situ seawater, macroalgae, macrocrustaceans and associated fauna (cruise GoMRI-II, November 15-17 2012, stns 1-18, data available for all) aboard the R/V Pelican cruise id PE13-14 was targeted to repeat sampling of previously studied hard banks and adjacent deep waters west of the mouth of the Mississippi River and extending east to offshore Alabama, an area encompassing roughly 27 degrees 58'N to 29 degrees 26'N and 87 degrees 34'W to 91 degrees 01'W. Submitted metadata are ADCP, CTD, Marks and Cruise Track Data.
