Abstract

ARABUOR.PDF UOR Data Documentation Introduction During the two Arabesque cruises, nearly 50 tows were completed using the Undulating Oceanographic Recorder (UOR). This document describes the UOR data from both cruises : Discovery cruise 210, August - September 1994 and Discovery cruise 212, October - November 1994. It includes measurements made from the standard CTD unit (salinity derived from conductivity, temperature and depth) and from an additional fluorometer attached to the UOR. This document details the protocols used during data acquisition and processing. N.B. Please note that all times given are in GMT which is local ship time minus four hours. Where’s the Data ? The data files can be found in the UOR directory. There are two subdirectories - DI210 and DI212 - which relate to the cruises on which the measurements were made. Each file, UORnn.txt refers to a single UOR deployment or tow, where nn is the tow number. The files are ASCII text files and each have a 30 line header which gives general details on the size of the file and the number of data channels it contains. The data listings then follow. Note that each data cycle has an associated quality control character flag, which may take any of the following values: · G good data · S suspect or bad data · I interpolated data · N null data (not measured) Further details on how these flags were assigned is given below. Instrumentation and Deployment Details The 49 tows, encompassing several hundred profiles were taken using the Plymouth Marine Laboratory UOR incorporating a Chelsea Instruments CTD (pressure sensor, conductivity cell, platinum resistance thermometer) and a purpose-built fluorometer which is described in Aiken (1981). A SeaTech 25cm pathlength transmissometer, tilt and roll sensors and an array of upwelling and downwelling radiance and irradiance sensors were also included, although that data is not available here. The UOR was towed approximately 350 metres behind the ship at speeds
