Ever wonder what the Floating Shed in the bedford Basin Is?

From BIO:

The DRDC Atlantic Acoustic Calibration Barge is located in Bedford Basin, about 5 km by water from DRDC Atlantic. The main function of the Barge is to conduct acoustic calibrations of sonar transducers such as hydrophones and projectors, in a free field salt water environment. It is also used to test and evaluate many other types of sea-going scientific apparatus and military equipment. The chief customers are DRDC Atlantic defence scientists, the Canadian Forces, other government departments and Canadian industry. It is equipped like a combined floating laboratory and workshop. The 300 tonne barge is 36 metres long by 17 metres wide. The main working area is covered by an enclosed heated deckhouse 30 metres by 13 metres, which allows calibrations to be performed year round. The hull contains a rectangular well 18 metres by 9 metres through which equipment under test can be lowered into the water. The barge is moored 1 kilometre from the nearest shore in a water depth of 42 metres. A 10 tonne crane is fitted to the outside deck for unloading equipment and a 5 tonne travelling crane is used to position apparatus over the well. Rotating stations with capacities up to 7 tonnes are available to position sonar transducers at any required orientation and depth.

CFAV Quest also takes part in this reasearch. from DRDC:

the research, development and testing of the systems needed by the Canadian Navy to maintain a state of readiness for maritime warfare often requires that the laboratory be transported to the field so that the work can be performed under “real world” conditions.
To this end, Defence R&D Canada — Atlantic (DRDC Atlantic) employs the Canadian Forces Auxiliary Vessel Quest. Maintained by the Navy and manned by Maritime Forces Atlantic Auxiliary seamen, Quest conducts 7 to 10 trials per year, spending up to 160 days at sea.
These trials encompass a wide range of R&D activity, from research on the acoustic properties of the ocean to experiments on ship signatures and safety. As well, the evaluation of prototype acoustic detection systems is often the first step in the process leading to procurement of new systems for the Navy.
This broad range of R&D activities requires a capable and versatile vessel; thus, Quest was designed with spacious laboratories, large working deck areas, and very capable marine cranes and specialized equipment handling systems.
The vessel was designed with a large margin of stability and this, combined with its roll–stabilization system and constant displacement systems, makes Quest a safe and stable platform from which to carry out experiments, even in heavy seas.
Of particular note are the acoustic quieting features of the vessel, which reduce the ship’s radiated noise to virtually undetectable levels when the vessel is configured in its “quiet state”.
Quest has conducted research in support of other government departments, universities and Canadian industry, where joint research is mutually beneficial. Quest has participated in Canadian and NATO naval exercises requiring the operational evaluation of prototype equipment.
