  1. These data are accessed under the the GLOBEC homepage-->data-->process-->{year}-->alongtrack
  2. These are single ascii files per cruise with several variables merged to one minute (interpolated) time steps. The user should be aware of the availability of the unmerged "raw" data at http://www.wh.whoi.edu/~albscs (for Albatross data) if they want the actual data which, for some sensors/variables, was recorded as frequent as every 5 seconds and by more than one instrument. Contact Jim Manning for authorization to access these data.
  3. The first column is the time stamp which, for Albatross convention, is "yrday1_local" which means, for example, that a time of "1.5" represents local noontime on Jan 1st. Note that the "Albatross convention" may change so the user must pay attention to the time stamp variable name in the future cruises.
  4. I have been processing Albatross alongtrack data on an "as requested" basis so just let me know when you want a particular cruise that is not already posted.
  5. We all understand this data (shipboard temp, salt, wind, etc.) should be treated as uncalibrated records and should not be used other than exploratory purposes.
