## The buoy network must meet NOAA Mission Goals and IOOS Societal Goals

**Notes:**
NOAA is the ONLY agency that has responsibility for some aspect of all the IOOS goals.

## 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**

## Next steps:

_**Next steps:**_
**. Transition technology to users**
**. Increase deployment depth - fiber optic cable**
**. Increase system throughput**
**. Develop under-ice capability**

## 2005 Data

**2005 Data**

**2003 Data**

**Observations of Oxygen and Temperature**

**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. **
