SBE Fluorescence values are almost constant with some spikes for Events #372 to #567. The odd fluorescence signals may be related to the extremely low extracted chlorophyll values in the northern part of the cruise. (See file 2010-18_Bottles_plus_CTD_Data.xls) Post-cruise calibrations were used for all sensors on the CTD except the transmissometer. No estimate can be made of the precision of the SBE Dissolved Oxygen channel since there was no DO sampling. The availability of a post-cruise calibration in late December 2010 should minimize errors due to calibration drift, but not those due to slow response time. SBE:pH data have been removed from the file because of quality concerns. ***************************************************************************************** !--1--- ---2---- --3-- ---4--- ---5---- --6--- --7-- -8-- !Pressu Temperat Trans Fluores Salinity Oxygen Oxyge Numb !re ure: missi cence: :T0:C0 : n: er_o !
