## Great Lakes Observing System

**IOOS Regional Grantee Data Management Workshop**
**February 7, 2008**
**NOAA Coastal Services Center**
**Charleston, SC**

## The Great Lakes

**Notes:**
8 states, 2 provinces
1.5 million registered watercraft
encompasses 20 percent of the world’s freshwater supply ---
water-related recreational activities are valued at $15 billion annually 
Largest freshwater ecosystem in the world 5,000 tributaries and 6500miles/11,000 km of shoreline. Provides drinking water to more than 40 million US/Canadian citizens

## Slide 3

**Notes:**
GLOS Subsystems
9 subsystems – 10 to 12 subject matter experts within the domain

## Slide 5

**Notes:**
This slide depicts the current installed base of observing systems.
There are 8 NDCB buoys operating in the U.S. portion of the system and 10 instrumented fixed structures or C-Man stations.
There are approximately 50 nearshore water level monitoring stations in operation on the U.S. side of the Great Lakes and interconnecting waterways.
There are nearly 350 stream gauging stations monitoring flows in the 78 major watersheds in the U.S.
A major investment is made across the region on meteorologic observations as well.
Marine observations of water chemistry and biologic activity are also conducted by several federal agencies and academic institutions.
This slide, however, does not showcase the paucity of observation of specialized variables, nor the lack of local detail needed to manage resources.
