Lake Huron is the third largest freshwater lake on Earth. Its lake shore is 3827 mi/ 6159 km long and the average depth is 195 ft/ 59.4 m. Lake Huron and Lake Michigan have the same surface elevation and are technically a single lake. The Straits of Mackinac connects Lake Michigan and Lake Huron. Many ships have sunk in the Straits, due to storms over the past years, some of them yet to be found. The Straits of Mackinac Underwater Preserve tries to preserve Michigan’s shipwrecks. The preserve contains more than thirteen recognized shipwrecks. One of them is the Martin Stalker.

Scuba Diving in Ardrossan Barge, Yorke Peninsula, South Australia Australia
The Ardrossan Barge measured 140 ft/42.6 m in length, 26 ft/7.9 m width, 13.5 ft/4.1 m depth and had a capacity of 450 cubic yards. The steel barge had 9 watertight compartments and 6 sets of hopper doors, which were originally opened by hand but later converted to hydraulic operation.
The barge had been used to dump spoil from dredging operations in Port Adelaide and most major out-ports, but became surplus to requirements after the commissioning of two self-propelled barges in 1978. On April 11th, 1984 the motorized barge Denis O’Malley towed No. 5 dumb hopper barge to a site one nautical mile south of the Zanoni shipwreck.
The spot is recommended only for advanced scuba-divers who should also keep an eye out for great white sharks, which are common visitors when the snapper run is at its peak.
