We’ve told you all about the CTD (conductivity, temperature, depth), which is one of the primary suites of scientific equipment used by oceanographers.
The world’s oceans keep us alive! Did you know that every second breath you take has been created through ocean photosynthesis?
So think of the oceans as the world’s lungs, the currents are like the veins moving nutrients around, and the CTD is the way we are able to monitor the blood pressure.
Some of the questions oceanographers ask and are able to answer with the CTD are:
- Is an ocean current the same temperature it was last year?
- Is it moving at the same speed?
- Has it moved somewhere else?
- And if it’s changed, what is influencing these changes?
The CTD is also used to collect samples for gas analysis and phytoplankton samples.
We’ve recently taken delivery of the 36 bottle CTD rosette and it’s now been assembled – it looks amazing!
Here are photos of the CTD compartment under construction in the shipyard and the 36 bottle CTD rosette assembled in the CSIRO Marine and Atmospheric Research Laboratories in Hobart.
All the pieces to this puzzle are falling into place!
