Overview The purpose of the float DAC was to create a consolidated float data set usable by scientists for statistical studies and incorporation into ocean models. The intent was that the collected data be the best and cleanest version available. Data were transferred to WDC-A as well as being archived and made available by the DAC. The Float DAC received most major historical data sets, checked them and transferred them to WDC-A. The DAC also received the bulk of the WOCE data sets, including the Lagrangian component of profiling ALACE floats. When data were acquired by the DAC, an attempt was made to also acquire background information (data reports, e.g.) and a list of references. The Float DAC stopped receiving data at the end of 2001. The NetCDF versions of the data found here were finalized by Dr.Charles Sun at NOAA, with our thanks. Data Processing The Float DAC expected to receive "final archive versions" of data already quality-controlled and calibrated by each PI. Some checks were be made to see that the obtained data looked reasonable. Exten- sive quality control checks were not be performed. PI's were noti- fied of any anomalous data and these were flagged. Access to Float Data The released data files are available as compressed (zip) files in either NetCDF (WOCE) or an ASCII format (historic) from http://wfdac.whoi.edu. They are also available in the form they arrived from the PI ("raw"). If you use data from this archive, please reference the Principal Investigators.
