The Long Term Upper Ocean Study (Lotus) : cruise summary and hydrographic data report, Oceanus 129--October 1982
MetadataShow full item record
OCEANUS cruise number 129 (28 October-4 November, 1982) was the eighth in a series of cruises to the Long Term Upper Ocean Study (LOTUS) area centered at 34°N, 70°W. In the LOTUS area seven SOFAR floats were launched, two moorings were recovered (a LOTUS surface mooring and a C. S. Draper Labs profiling current meter mooring), and a surface mooring which replaced the one recovered was set. Seven CTD stations were also completed in the LOTUS area. Outside the LOTUS area a subsurface mooring was set in the Gulf Stream in cooperation with H. Bryden's (WHOI) Gulf Stream Observations project, and a WHOI engineering mooring at Site D was recovered, examined and redeployed. In addition several XBT sections were made, one along 70°W between 40°N and 34°N, a second surveyed a cold core ring discovered during the trip to the LOTUS area and a third was made in the vicinity of the Gulf Stream Observations mooring. Part I of this report is a summary of the major cruise activities and part II presents the hydrographic data (CTD and XBT) collected during the cruise.
