For methods and equations used to calculate the Chlorophyll, POC, and Gamma values found in the directories here please see: Boss, E., Picheral, M., Leeuw, T., Chase, A., Karsenti, E., Gorsky, G., Taylor, L., Slade, W., Ras, J., Claustre, H., 2013. The global distribution of particulate absorption and attenuation in the surface ocean; Contribution of the Tara Oceans expedition. Methods Oceanogr. http://dx.doi.org/10.1016/j.mio.2013.11.002. The files with Chl, POC, and Gamma data are for both 1minute and 1km^2 resolution. - The 1min data are reported by day (in folders by leg). There are also files with all Oceans 1min data, and all Arctic 1min data. - The 1km^2 data are reported by leg, and again there are separate files for the entire Oceans and Arctic expeditions. - Finally, there is one large file for each the 1min and 1km^2 resolution data with all legs of both expeditions included, found at: ftp://triton.umeoce.maine.edu/users/boss/Tara/TaraArctic_ProcessedACS/ChlPOCGamma/full_TaraOceansArctic_ChlPOCGamma/ Parent directories for all of these data are: Oceans: ftp://triton.umeoce.maine.edu/users/boss/sediment/Tara/processed_data/Chl_Gamma_POC/ Arctic (a.k.a. Tara Oceans Polar Circle): ftp://triton.umeoce.maine.edu/users/boss/Tara/TaraArctic_ProcessedACS/ChlPOCGamma/ The 1-minute resolution data are calculated using the a_p and c_p spectra submitted to NASA’s SeaBASS and found on the MISC Lab ftp at: Tara Oceans: ftp://triton.umeoce.maine.edu/users/boss/sediment/Tara/processed_data/ascii_files/ Tara Arctic: ftp://triton.umeoce.maine.edu/users/boss/Tara/TaraArctic_ProcessedACS/ The 1-km^2 resolution data are binned from the 1-minute data. The “DateIn TimeIn” and “DateOut TimeOut” columns represent the dates and times the ship entered each square km reported on. The lat/lon are the center of each square km, and all others values are the median of values from within the sq. km. Spectra at the 1-km^2 resolution can be found at: Tara Oceans: ftp://triton.umeoce.maine.edu/users/boss/sediment/Tara/processed_data/1km_bins/ Tara Arctic: ftp://triton.umeoce.maine.edu/users/boss/Tara/TaraArctic_ProcessedACS/1Km_Binned/
