We are now posting the data
we are collecting on the river. Check back each day to see the new data
and the new highlights!
You may want to review the Tools
of the Trade to understand
the methods and tools used to collect the data.
Below the current data is the data
Tamara and the volunteers collected over a two week period in August
1999.

Tamara always tries to be as consistent as possible
when collecting her data. She uses the same methods of observation in
the same locations and generally at the same time of day. This is important
when she makes comparisons over time and from one location to another.
In order to answer her research questions, she will need to observe
the dolphins over a long period of time.
Please note that the data below represents only
partial data. The data posted does however, give an accurate representation
of changes over time and location.

Area Maps
In order to make comparisons and draw conclusions,
you may want to print the area maps and plot the location of the dolphins
spotted along with other environmental data collected.
