Abstract:
A Severe Environment Surface Mooring (SESMOOR) was designed to make long term meteorological and near surface
oceanographic measurements in areas where harsh envionmental conditions prevail. SESMOOR was deployed in the North
Atlantic Ocean approximately 300 km southeast of Halifax, Nova Scotia for 141 days during the winter of 1988-89.
Meterological data were acquired from two Vector Averaging Wind Recorders (VAWR) located on top of a specially designed
buoy mast and included air temperature, relative humidity, barometric pressure, wind velocity, solar and longwave radiation. Sea
surface temperature was also acquired by the VAWR. Current velocities and sea temperatures were obtained from two Vector Measuring Current Meters (VMCM) at 20 and 50 meters below the sea surface.
This report discusses instrument performance, data quality, pre-and post-deployment calibrations, data telemetry, data
processing procedures. This report also presents the data in a variety of displays.
