Alaska Coastal Current Monitoring Quarterly Tasks

2007 Quarterly Project Tasks:

1st Quarter Tasks (October 1, 2006 - December 31, 2006)
Status: Complete

Tasks to be performed:

Project funded.

Progress report:

Monthly CTD sampling at GAK 1 completed Begin acquiring, archiving, and processing Middleton Island and Prince William Sound buoy data. Data acquired and quality controlled through 2003. Continuing data archiving and quality control for succeeding years.

2nd Quarter Tasks (January 1, 2007 - March 31, 2007)
Status: Complete

Tasks to be performed:

Attend Alaska Marine Science Symposium. Monthly CTD surveys, recover and re-deploy GAK 1 mooring. Conduct post-calibrations of instruments. Begin acquiring, archiving, and processing Middleton Island and Prince William Sound buoy data.

Progress report:

Monthly CTD sampling at GAK 1 completed Archiving and quality controlling Middleton and Prince William Sound weather buoy data continues. Graduate student starting to generate heat fluxes on earlier years. GAK 1 mooring recovered and re-deployed. The mooring was re-deployed without the ISUS nitrate sensors provided by the Alaska Ocean Observing System. These were not deployed because the batteries for these instruments were bad. New batteries would have required a long delay (2.5 months) in the deployment. Recovered instruments being prepared for post-calibrations at Seabird Electronics. Project personnel attended the Alaska Marine Science Symposium.

3rd Quarter Tasks (April 1, 2007 - June 30, 2007)
Status: Complete

Tasks to be performed:

Monthly CTD surveys. Complete post-calibration on mooring instruments, process mooring and CTD data.

Progress report:

Monthly CTD sampling at GAK 1 completed and results posted on the project website (http://www.ims.uaf.edu/gak1/). Archiving and quality controlling Middleton and Prince William Sound weather buoy data continues. Our results for this year indicate that the deep temperatures at GAK 1 are the coldest observed in the past 30 years. A graduate student is generating the winter heat fluxes for earlier years and the present year in order to establish the causes for these cold waters. GAK 1 mooring instruments are being post-calibrated.

4th Quarter Tasks (July 1, 2007 - September 30, 2007)
Status: Complete

Tasks to be performed:

Monthly CTD surveys, update heat fluxes. Submit annual report.

Progress report:

Monthly CTD sampling at GAK 1 completed and results posted on the project website (http://www.ims.uaf.edu/gak1/). Heat flux observations were updated.
