abstract = {As analysis of imagery and other science data plays a greater role in mission
execution, there is an increasing need for autonomous marine vehicles to
transmit these data to the surface. Communicating imagery and full-resolution
sensor readings to surface observers remains a significant challenge. Yet,
without access to the data acquired by an unmanned underwater vehicle (UUV),
surface operators cannot fully understand the mission state of a vehicle. This
paper presents an architecture capable of multihop communication across a
network of underwater acoustic relays. In concert with an abstracted physical
layer, CAPTURE provides an end-to-end networking solution for communicating
science data from autonomous marine vehicles. Automatically selected imagery,
SONAR, and time-series sensor data are progressively transmitted across
multiple hops to surface operators. To incorporate human feedback, data are
transmitted as a sequence of gradually improving data “previews.”
Operators can request arbitrarily high-quality refinement of any resource, up
to an error-free reconstruction. The results of three diverse field trials on
SeaBED, OceanServer, and Bluefin AUVs, with drastically different software
architectures, are also presented.}}
