Underway Data

CalCOFI aims to continuously collect surface oceanographic and meteorological data on all CalCOFI cruises.  While all available data is accessible on a per cruise basis, it is only surface temperature, salinity, and chlorophyll concentration that are actually processed into a final data product.  In many cases, faulty data collection may have resulted in questionable and incomplete data sets.  In an attempt to make Underway Data as useful as possible, detailed notes accompany each cruise in order to clarify and explain data shortcomings and workarounds.  If data was not collected, or was uncorrectable, it is labeled as unavailable. Some examples of data that may be available are:

Ship information:

  • Ship speed
  • Ship heading
  • Ship position

Meteorological:

  • Wind speed
  • Wind direction
  • Relative humidity
  • Barometric pressure
  • Air temperature
  • PAR

Oceanographic:

  • Surface temperature
  • Salinity
  • Fluorometery
  • Speed of sound
  • ADCP
