OSDT team and Monterey Bay Aquarium Research Institute (MBARI) team jointly demonstrated live data from Free Ocean Carbon dioxide Enrichment (FOCE) deployment at the 6th IEEE International Conference on Distributed Computing in Sensor Systems (DCOSS '10). FOCE is designed to understand the impact of ocean acidification on marine life. The FOCE system is installed in deep waters in the Monterey Bay Canyon. FOCE is connected to Monterey Accelerated Research System (MARS: http://www.mbari.org/mars) deep-sea cable-to-shore observatory node in Monterey Canyon in 900 meters depth at the end of the 52 kilometer cable. The MARS cable provides Gigabit Ethernet communications over optical fiber, and hence supports sensors with very high data rates.

MBARI team members have collaborated with OSDT team to design and develop data plane and control plane software framework for FOCE experiments. The framework is based on Open Source DataTurbine middleware. DataTurbine provides asynchronous communication links between distributed components, and is particularly well-suited to streaming sensor data. DataTurbine provides a subscribe-publish API, and also supports discovery of data sources at run-time.
