Oceanographic research projects often deploy underwater sensor systems in the sea. These are retrieved from deep water by remotely releasing them from their moorings. However, the mooring anchor, shackles and cables can not be easily recovered.
Australian engineers have therefore developed a ‘retrieval pod’ to enable the recovery of moorings. They attach this directly to the remotely released underwater devices.
The retrieval pods are reusable, require minimal construction skills and can even be assembled from basic equipment available at most hardware or boating stores, making them both convenient and low-cost.
