Objectives:
1. Provide temperature and current velocity data for hydrodynamic model
2. Quantify resuspension during the spring
3. Provide size data of suspended particles

Methods
• 1. Deploy acoustic Doppler velocity profilers and strings of temperature sensors at selected locations in the outer bay throughout the year, and in the inner bay between April and October
• 2. Deploy tripods with transmissometers and pressure sensors in the inner bay during the spring
• 3. Make observations with a LISST sensor to measure particle size of suspended sediment
• 4. CTD casts

Deployments1. Winter 2008-2009: currents and temps at
stations 1-5, waves at station 22. 2009: currents and temps at all 6 stations,
waves at stations 2,4,5, and 6, attenuation at stations 4 and 6, LISST data at station 4
3. Winter 2009-2010: currents and temps at stations 1-3, and 5, waves at 2 and 5
4. 2010: currents and temps at all stations, waves at 2 and 4-6, attenuations at 4 and 6

Status of data1. 2008-2009 and 2009 temperatures
have been quality controlled and archived
2. 2008-2009 and 2009 currents have been provided to Dima but not quality controlled
3. All other data has been downloaded but not quality controlled

Yet to do:
1. Do quality control and archive the data
2. Attempt to retrieve the missing moorings
3. Look for hypoxia?4. Analyze the data???
