Real-time Environmental Coastal Observation
Network (RECON)

• High bandwidth, wireless Ethernet-based system
• Real-time, secure data access
• Portable, low cost buoys and fixed platforms of
  opportunity
• Universal sensor interfaces
• Guest port access data delivered to a common
  database or a single user
• Developing partnerships with Federal, University,
  and State components to operate and maintain
  Observation sites

Observations of Oxygen and Temperature
2005 Data
2003 Data
Comparison of oxygen decline in Erie central
basin. Thermocline in 2005 is slightly thicker
and lower in temperature than 2003 results.
Oxygen decline (less than 3mg/l) in 2005 occurs
later in the year falling at a slower rate.
