Hydro International –

The world’s best known estuarine lagoon has historically importance for sheltering the City of Venice and is an ever-changing environment with only 8% covered by land, 12% by open water and the remaining 80% by mud flats, tidal shallows and salt marshes.

This geographical setting, hosting complex ecosystems, is influenced by tidal cycles entering through three sea inlets and freshwater and sediment supplied by river influx.

The Venice Institute of Marine Science (ISMAR-CNR) is engaged in research and monitoring projects of the lagoon.

Monitoring of changes to the environment is becoming ever more important with changing sea levels and as the human impact increases with the MOSE flood protection project enabling the closing of the sea inlets and dredging activities.

Kongsberg Geoacoustics has been was invited recently by the institute to demonstrate their technology for gathering high-resolution bathymetry data with the aim of effectively covering large very shallow water areas with portable installation, providing highly repeatable data to allow monitoring of even smallest changes through time.

Cairns Post –

A Brinsmead man has been discharged from Cairns Base Hospital after being stung by an irukandji jellyfish in a dive excursion gone wrong. Malcolm Frost, 26, was diving with friends at Double Island late on Tuesday when he was stung.

He was taken to Palm Cove where lifeguards were alerted about 5.15pm. Lifeguard Lana Shanks, who was on duty at Palm Cove, said Mr Frost was in severe pain and had difficultly breathing.

Ms Shanks called an ambulance before administering bottled oxygen to Mr Frost and using three bottles of vinegar to treat the stinger wound on his lower back.

“When you’ve already used vinegar and administered oxygen, you just need to reassure them,” Ms Shanks said of stinger victims.

“They’re very restless and they won’t sit still.

“When you looked into his face, you just knew he was in pain.”

While Mr Frost was wearing a dive suit when he was stung, North Queensland Surf Lifesaving regional manager Colin Sparkes said the irukandji barb may have penetrated through a tear in the suit or an exposed area of skin.
