The allocation of the variables in each file is shown in the table below. For all cruises the data are available in several formats and can be downloaded by clicking on the ACF IGOR CDF and/or ICT link in the download column.

The data are stored in a native ascii ACF format, defined by our group. The same data are also available as an IGOR text file (.itx). IGOR is a scientific graphing, data analysis package from Wavemetrics Inc. The plotting section of this site uses the ACF data converted into a binary netCDF file format. While not directly viewable the file may be downloaded by clicking on the "CDF" link. Projects starting in 2004 also have data available in the ICARTT data format. To download click on "ICT". The ICARTT files are ascii files that are based on the NASA AMES standard.

Some data files from recent cruises may be password protected. To obtain a password, please contact Jim Johnson or Timothy Bates.

Moving the cursor over an "Info Icon" and/or clicking provides additional information on the variables.
