2604 Notes

Cast 1 is CalCOFI CTD. Due to Winch issues, Cast 2-112 are using the Ship's CTD. pH, Transmissometer, SUNA data no longer collected after station 1.

Par Sensors: Historically CalCOFI uses a Par/Irradiance sensor from Biospherical. On 2604 CalCOFI used a par/logarithmic sensor from SAtlantic. SPAR as well.

Oxygen sensors:
Stations 2-25, please rely on secondary sensor. Primary sensor is questionable.
Stations 1 and 26-112, both sensors are good.
