Scientific HAB studies have
relied on collecting discrete water samples from hard-to-schedule,
expensive research ships. Other studies use anchored or drifting sensor
buoys which cannot be repositioned, do not enter coastal areas where
HABs cause the greatest damage, and have limited operational
lives. We are developing: a HAB Investigation Telesupervised
Adaptive Sensor System (HABITASS) to address these limitations.

The National Oceanographic
and Atmospheric Administration (NOAA) is
expanding an existing Ocean Atmosphere Sensor Integration System
(OASIS) fleet that performs in-situ air and ocean surface observations.
By extending the capabilities of OASIS to include a telesupervision
software architecture, adaptive autonomous fleet control, and
HAB-specific sensors, HABITASS will provide:
- Dynamic taskability and adaptation
- Greater insensitivity to weather than satellite
systems
- Greater access to coastal waters than buoys
- Centralized analysis of collected data
- Real-time observation by remote oceanographers
|
Each platform is tasked from and communicates its data back
to the Tele-Science Workstation.
By supporting oceanographers with multi-robot control software and
automated science data analysis, this work will form a critical segment
of the ocean portion of the Earth Science Sensor Web concept,
supporting the prediction of outbreaks of HABs several days in advance
of their occurrence, and providing more detailed information about the
severity and the duration of any given outbreak.
