In this project, researchers at the Texas A & M University performed analysis, quality control, and adjustment of the transmissometer data from the Hawaii Oceanographic Time-Series (HOT) and the Bermuda Atlantic Time Series (BATS) data sets collected during the last decade. These data were collected at fixed locations in the Atlantic and Pacific Oceans and provide important data on seasonal and interannual variations, covering all seasons at both sites. The unprocessed or pre-processed data reside in the appropriate laboratories, but several different characteristic errors in some of the data, make them unreliable for modeling and analysis. TAMU researchers analyzed the data, controlled their quality and made necessary adjustments.

The adjusted data can now be used for assessment of the regional and seasonal Beam Attenuation - Particulate Organic Carbon relationships. Corrected data are posted on the TAMU web-server ( http://oceanography.tamu.edu/%7Epdgroup/DataDir/SMP-data.html) and are in the JGOFS database.
