The Continuous Plankton Recorder Survey of the North Pacific: CTD data
CTD Data

A variety of instruments have been attached to the CPR to record physical variables (Table 1). Simple temperature loggers have been most commonly used and 3 CTDs have been trialled. The most recent, the Brancker XR620, has proven to be the most reliable, returning 100% of the data in 2 full deployments along the east-west transect (previous Chelsea Instrument’s CTDs suffered from vibrations occurring during the tow and often stopped recording). Figure 1 shows the CTD fitted under the tail section of the CPR and Figure 2 some of the data.

In all cases position of each data record is calculated from the ship’s log and the internal clock of the instrument. Such instruments can be fitted to each CPR, it is only financial constraints that limit their deployment. The Brancker will remain on the east-west CPR during its 2008 deployments.
