Invitation to Participate in the 2010 Secchi Dip-In!
The Seechi Dip-In, co-sponsored by NALMS, the EPA and Kent State University, is now in its 17th year!
You are cordially invited to participate in this year’s Secchi Dip-In, which will run from June 26 - July 18, 2010
This three week event in June and July continues to demonstrate that volunteers can collect quality data on an international scale. How do we know it is quality data? Because the Dip-In solicits the participation of volunteer programs such as yours that train its volunteers. With your help, we have accumulated over 39,000 scientifically-useful records of data.
The Dip-In is a network of volunteer programs and volunteers, each supplying the data for state and local programs and, together with all the other Dip-In participants, gathering and providing continent-wide (and world-wide) information. Because of long term participation by volunteer programs, as of 2008 we have 1,876 water bodies with 5 or more years of data. Of those water bodies, 202 were exhibiting significant levels of change. Are changes in 11% of North America's waters significant? It might depend on whether it is "your" lake or stream that is changing. The Dip-In allows you to see how a water body is faring relative to neighboring bodies in other states and programs.
The Dip-In accepts data from a wide range of turbidity instruments such as Secchi disks, turbidity tubes and turbidimeters, and solicits other variables such as temperature and oxygen. The Dip-In also encourages the involvement of programs that sample rivers and streams, estuaries, and marine environments.
