Data Manager Miles Jordon has been tracking our voyage progress and the deployment of various scientific instruments and helicopter work.

The NIWA buoy deployment relates to the sea ice accelerometer work conducted by Dr Alison Kohout early in the voyage (see previous blog post). At each ‘ice station’, where we conduct scientific work on the ice, a CTD (conductivity, temperature and depth) instrument and TMR (trace metal rosette) are deployed in open water behind the ship. The CTD gives scientists information about the physical and chemical properties of the sea water and the trace metal rosette measures the amount of iron in the water, which is important for phytoplankton and sea ice algae growth.

(As of Sunday the SIPEX team were at ice station 4.)
