1. Water Quality in the Alaskan Arctic By Kaylan Duthie December 1, 2005

3. Laminaria Solidungula

5. Kaylan Collecting Kelp

6. Data Collection Temperature, Salinity, Dissolved Oxygen Total Suspended Solids (TSS) Photosynthetically Active Radiation (PAR)

7. Objectives Determine if we have discrete sample periods Determine if water column parameters are related

8. The Northern Coast of Alaska

9. Feature Classes Alaskan Coastlines –www.mms.gov/ld/al aska/htmlwww.mms.gov/ld/al aska/html Synoptic Sites Alaska Albers Equal Area Conic

10. Depth (m)

11. Time Series Tables 8 data types 1,140 records

12. Discrete Sample Periods? July 24, 2004July 31, 2004

13. Discrete Sample Periods? July 31, 2004August 6, 2004

14. Discrete Sampling Periods? July 31, 2005July 19, 2005

15. Discrete Depths? July 31, 2004; 2m July 31, 2004; 4m

16. Discrete Depths? July 31, 2005; 2m July 31, 2005; 4m

17. Water Column Parameters Correlation/relatedness shown among parameters? –Temperature –Salinity –Dissolved Oxygen –Photosynthetically Active Radiation (PAR) –TSS

18. Temperature Temp (C°) ↑ NE ↓ SE

19. Salinity Salinity (ppt) ↓ to the NW, farther from land

20. TSS TSS (mg/L) ↓ to the NE

21. Dissolved Oxygen DO (mg/L) ↑ to the NW, farther from land

22. PAR PAR (µEphotons/m 2 /s ↑ to the E, SE

23. Conclusions Sampling periods not totally discrete –More time in between? Depths not totally discrete Salinity and DO inversely related DO and PAR directly related Salinity and PAR inversly related TSS inversely related to PAR and DO, directly related to Salinity

24. Future Work Find Boulder Patch feature class Statistical analysis? Compare T,S,DO,PAR to determine if discrete samples
