Hydrographic, biological, and nutrient characteristics of the water column on the Louisiana shelf, July, 1986
In June 1985, a focused study was initiated to assess the spatial and temporal extent, intensity, and potential causes of oxygen depletion in the northern Gulf of Mexico. Hypoxic bottom waters were studied along two transects (one off Cat Island Pass near Cocodrie and one off Belle Pass near Port Fourchon). These cruises were continued in 1986 but on a single transect (see LUMCON Data Report No. 6). In addition, a shelf-wide cruise was conducted from the Mississippi River to the Texas border during July, 1986. Stations occupied during this cruise were similar to those sampled during shelf-wide cruises in 1985. The intent of these cruises was to provide comparative information on the temporal variability of oxygen-depleted bottom waters on the Louisiana shelf.The first part of the cruise was conducted on the R/V Acadiana between July 7 and July 10. Rough seas prevented continuation on the smaller ship. The remaining stations were sampled from on board the R/V Pelican between July 16 and July 17. While not synoptic in coverage, a few mid-depth stations were reoccupied during the second leg and hydrographic conditions were similar on the two dates.
