The sediment trap component of this work has been ongoing, but the surface flux and sub-surface biogeochemical mooring packages were unable to be deployed as planned on 17 March this year.
With a lot of hard work by the science and engineering teams in recent months, and a break from the weather gods, time series from the moored sensors and samplers has now recommenced.
‘We’re all very pleased to be here’ said Tim Moltmann, IMOS Director. ‘We’d particularly like to thank the Marine National Facility team for their unerring support in getting us back in the water. IMOS couldn’t do this important work without them.’
The SOTS site is located at 47° south, a harsh, remote location where the swells and waves make it very challenging to keep a surface mooring package in place. IMOS continues to take on this challenge because the measurements provided are of national and international significance in understanding global climate cycles.
Maintaining the SOTS site is enabling other science programs to build around our sustained observing program. It also has great potential to support current and upcoming satellite missions measuring surface waves and ocean surface topography.
