  Abstract: Passive Acoustic Monitoring (PAM) usually requires specific moorings and instruments which are both expensive and cumbersome to deploy. Here we present the TOSSIT, a low-cost ($10k), hand deployable, and acoustically silent PAM mooring. It is bottom mounted, ropeless, and records acoustic pressure (and optionally temperature) in the water. A TOSSIT consists of a commercial off the shelf (COTS) PAM recorder and a COTS underwater acoustic release, mounted on a rope-free and shackle-free thermoplastic frame with built-in buoyancy (syntactic foam plates). TOSSIT can easily be deployed from platforms ranging from small (e.g., rigid-hull inflatable) boats to large oceanographic vessels or even commercial ships. This presentation will cover hardware presentation and showcase several TOSSIT experiments, including marine mammal monitoring in Cape Cod Bay and geoacoustic inversion on the New England Mud Patch [Work supported by the Office of Naval Research].
