Brief description

Tides are measured using a submerged pressure type gauge secured in a heavy concrete mooring in Nella Fjord in the Larsemann Hills near Zhong Shan station. Tidal records are retrieved from the gauge using an inductive loop lowered through a hole in the ice hence the gauge has been undisturbed since it was deployed. Documentation dated 2001-06-12 Zhong Shan Submerged Tide Gauge The gauge used at Zhong Shan was designed in 1991/2 by Platypus Engineering, Hobart, Tasmania.
