iSTAR Moorings
Description
Location of the 9 iSTAR moorings deployed in Feb 2012 by the crew of cruise ANA02C in collaboration with the Krea Polar Research Institute (KOPRI). 5 of the moorings were positioned at the ice shelf and 4 towards the front of Pine Island Glacier. Each iSTAR mooring is sub-surface to protect it from icebergs and surface activity. Mooring equipment includes:
- Aqualogger 520 PT temp./press. logger
- Aquadopp current metres
- ADCPs (acoustic Doppler current profilers) in buoy
- Aqualogger 520 PT temp./press. logger
- SBE-37 "Microcat cond./temp. logger
- IXSEA AR681 acoustic releases
- Glass floats
- Novatech xenon flash beacon
The moorings were collected in the Antarctic summer 2013-2014 by the science cruise on RRS James Clark Ross.
