abstract: "The Gulf Stream, which comes within 100 km
11+
of the United States coastline in both the Florida Straits and
12+
the vicinity of Cape Hatteras, is estimated to possess over 160
13+
TWh/year of technical energy capacity. To better understand
14+
the behavior of the Gulf Stream, whose flow resource varies
15+
in both space and time, a relatively sparse network of fixed
16+
acoustic Doppler current profilers (ADCPs) and shore-mounted
17+
high-frequency radar units have been supplemented by more
18+
granular but infrequent boat transect runs and undersea glider
19+
deployments. Collectively, these measurements provide highly
20+
granular data with respect to either time or space, but not both.
21+
This work represents part of a comprehensive effort to evaluate
22+
use of a solar-powered autonomous surface vehicle (ASV) fleet
23+
to supplement existing observational capabilities. The proposed
24+
solar-powered ASV can provide data with high spatial and
25+
temporal granularity, but comes with the challenge of optimally
26+
planning its mission in an adaptive manner. To address this
27+
challenge in this work, we propose a multilevel controller that
28+
fuses the A* search algorithm with an upper level waypoint
29+
selector and lower level heading control. Focusing on a critically
30+
important mission domain adjacent to Cape Hatteras, and
31+
relying on a Mid-Atlantic Bight, South Atlantic Bight Regional
32+
Ocean Model (MAB-SAB-ROM), we compare the performance
33+
of our proposed algorithm against several competing strategies.
34+
We demonstrate a significant performance improvement in
35+
terms of a dynamic coverage metric, both in comparison to
36+
competing strategies and to the existing observational network."
