The Scripps team is committed to expanding the spectrum of long- duration autonomous instruments available for observing the ocean and its processes. This project's objective is to develop an ocean profiling float, in the style of an Argo float, that can be deployed from aircraft through an A- sized (4.875-inch diameter, 36-inch long) sonobuoy chute. We believe that the availability of aircraft with an A-sized chute capability would allow an air deployable float with a multi-month lifespan to provide a unique capability to rapidly establish persistent area surveillance over regions of tens to hundreds of kilometers on a side. Our initial design target for an air-deployable float is 500-meter depth capability; Iridium communications; GPS locating; and 280 dives with a 1000 gm science payload using a 14-D-cell alkaline battery pack, or 450 dives with a 1600 gm science payload using a 10 D-cell lithium primary battery pack.
