Background• Assessment of AK’s
coastline began in 2002– AK Monitoring and
Assessment Program (AKMAP)
• Large coastline– Broken into regions– Sample separately http://yosemite.epa.gov/r10/OEA.NSF/Monitoring/Coastal+Study+Areas/
$FILE/alaska_02.jpg
• Can we “jump-start” long-term monitoring by examining historical data?
![Page 4: Advanced Monitoring Initiative: Arctic Coastal Data Mining and Assessment Project Carrie Parris*, Arny L. Blanchard*, Doug H. Dasher +, Hilary K. Nichols*,](https://reader036.fdocuments.net/reader036/viewer/2022062713/56649f445503460f94c65a39/html5/thumbnails/4.jpg)
• Assess the usability of historic long-term data for conducting post hoc AKMAP assessments
• Use GIS to develop a sampling grid that reflects the spatial density of resource characteristics– Sample GIS grid using EPA EMAP random
survey method to achieve spatially balanced design
– Summarize results using descriptive measures
What’s our process?
Methods of AMI
![Page 5: Advanced Monitoring Initiative: Arctic Coastal Data Mining and Assessment Project Carrie Parris*, Arny L. Blanchard*, Doug H. Dasher +, Hilary K. Nichols*,](https://reader036.fdocuments.net/reader036/viewer/2022062713/56649f445503460f94c65a39/html5/thumbnails/5.jpg)
AMI Process and QAPP• Acquire ANY datasets by searching
reports and publications– Enter into electronic spreadsheet– Reference and standardize the datasets
• Data validity: must be backed by rigorous and documented QA/QC efforts
• Data usability: Is the dataset indicative of overall status or suggest potential trends in temporal or spatial data?Georeferenced by documented latitudes and
longitude

Results of our data-mining
• ~20 reports• >450 unique stations
over time• ~200 physical
variables (sediment)– Heavy metals– Hydrocarbons– Grain size

What’s next for AMI• Perform the random sampling of the GIS
sample grid– Summarize the data using descriptive
measures and other statistical means
• Repeat for reports of biological variables– Have some reports but not meeting QAPP– Continue data-mining of biological datasets
• Create a searchable database of all the datasets– Make database available

Conclusions
• We can apply the method to other coastal regions
• Gain insights of status on temporal & regional scales
• Add to near-future Beaufort Sea AKMAP study
• Assist with designing future sampling efforts
