Currents and Sediment Transport in the Mississippi Canyon and Effects of Hurricane Georges
Mary Jo Richardson
Mississippi Canyon station locations and bathymetry. Contoursare in 100 m intervals. A. The upper portion of the map shows station locations from the 1998 cruise, including core, LAPS/ROV and mooring locations. B. The lower portion of the map shows station locations from the 1994 cruise. Transect lines and LAPS stations are numbered. Inset shows the study area in relation to the Louisiana coastline and Mississippi River Delta.
Back-scattered light (measured from the LSS) vs. particulate matterconcentration (PM) for the May 1998 cruise. All data are included; no division was made between surface and deeper water.
Temperatures at 33 and 3.5 mab for
deployment 1 and
B) deployment 2.
Progressive vector plot of currents at 3.5 mab during the first mooring deployment. Net transport is mostly cross-canyon (South) at 50 mab and down-canyon at 3.5 mab (East) with a cross-canyon drift. X's denote midnight.
Progressive vector plot of currents at 3.5 mab during the second mooring deployment. Net transport is down canyon (East). X's denote midnight. The passage of Hurricane Georges is denoted in year days. Note unequal axes that also differ from the unequal axes of Figure 8.
