Data Drilled for Stellwagen Bank National Marine Sanctuary
Dataset Identification:
Resource Abstract:
GeoTif images of chlorophyll, turbidity, and SST were created of the region. Then an EASI script was run on the geotifs to
extract the data (drill the data) from specific points (or bitmaps) in each scene for the timeseries. After the output was
created in text file format, they were opened up in Microsoft Excel and spreadsheets were created for each location. Chlorophyll,
turbidity, and SST are all contained in one spreadsheet bearing the name of the location. The drilled data shows the files
used for the data drill, the mean of the pixels used in the data drill, and the number of pixels used to calculate the mean
for each image used.

Additional information on resource:
Depending on the data type the time period of content can either be from 1997-2005, or 1985-2004. Output Columns: For text
files: The output from the .txt files is just a string of numbers extracted from each data file. Once the file is opened,
the first item in the list is the name of the file used to extract the data, the second item is the mean value of the pixels
containing good data for the region drilled, and the third item is the number of good pixels used to calculate the mean value.
Sample output:NE199710.AVG_MO_CH6_4.5.1_UTM.tif, 48.8724823,447 The file used was the turbidity file from October 1997, the
mean value extracted was 48.872423, the number of pixels used to calculate the mean was 447. For Excel spreadsheet files:
The Excel spreadsheet files contain several columns for each data type. CHL First column: image used to extract data from
Second column: mean extracted value from the image: Third column number of pixels used to calculate mean Fourth column: date
for image used: Fifth column: mean extracted value converted in to chlorophyll in micrograms per liter Sixth column: grand
mean, is the inter-annual monthly mean for the time series. This was calculated using the data from column five and copying
it into the appropriately number year column on the right then calculating a mean. Seventh column: Standardized Anomaly, calculated
as (Fifth col. - Sixth col.)/stdv of grand mean Turbidity First column: image used to extract data from Second column: mean
extracted value from the image Third column: number of pixels used to calculate the mean Fourth column: date for image used
Fifth column: mean extracted value converted into turbidity in 1/steradian Sixth column: grand mean, is the inter-annual monthly
mean for the time series. This was calculated using the data from column five and copying it into the appropriately numbered
year column on the right then calculating a mean. Seventh column: Standardized Anomaly, calculated as (observation - grand
mean)/stdv of grand mean SST First column: image used to extract data from Second column: mean extracted value from the image
Third column: number of pixels used to calculate the mean Fourth column: date for image used Fifth column: mean extracted
value converted into degrees Celsius Sixth column: copy of column five for further calculations Seventh column: grand mean,
is the inter-annual monthly mean for the time series. This was calculated using the data from column six and copying it into
the appropriately numbered year column on the right then calculating a mean. Time series graphs are also provided in each
Excel spreadsheet for all of the data for the time period.
