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.
