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.

Meteorological data have been gathered from a moored surface buoy at
34°N, 70°W in the Long Term Upper Ocean Study (LOTUS) experiment. The
meteorological results from the first year of LOTUS are encouraging; the data
returned from redundant sensors agree closely. Surface heat fluxes calculated
from the observations show the annual cycle of heat transfer to the mixed
layer.
This report documents the meteorological sensors on the LOTUs-3
(May 1982-october 1982) and LOTUS-4 (November 1982-March 1983) surface buoys.
It describes in detail the telemetry of the meteorological data via the ARGOS
satellite system. The measurements returned from LOTUS-3 are presented and
evaluated. Monthly heat fluxes at the sea surface are computed using the bulk
formulas and compared with the long-term means. The errors in the heat fluxes
have been estimated.
