Transmissometer data validation and correction for the Hawaii Oceanographic Time Series and Bermuda Atlantic Time Series data sets.
PROJECT DESCRIPTION:	The purpose of this proposal is to perform analysis, quality control, and adjustment of the transmissometer data from the Hawaii Oceanographic Time-Series (HOT) and from the Bermuda Atlantic Time Series (BATS) data sets collected during the last decade using different instruments. These data were collected at fixed locations in the Atlantic and Pacific Oceans and provide important data on seasonal and interannual variations, and cover all seasons. The unprocessed or pre-processed data reside in the appropriate laboratories, but we have observed several different characteristic errors in the data, making them unreliable for modeling and analysis in their present condition. We will analyze the data, control their quality and make necessary adjustments. The adjusted data will be used for assessment of the regional and seasonal Beam Attenuation - Particulate Organic Carbon relationships. After checking and adjustment the data will be posted on HOT, BATS and TAMU web-servers. We will analyze the data for seasonal and interannual variability. These data also will be available to the scientific community for the purpose of modeling ocean carbon cycles or evaluating the output from existing models.
