Thanks to your participation, the Dip-In continues to demonstrate that volunteers can collect quality data over an entire continent. We are attracting attention as a legitimate data gathering mechanism, not just an event in July. The Dip-In is a network of volunteer networks, each supplying the data for local programs and, together with all the other Dip-In participants, gathering and providing continent-wide (and world-wide) information.
Because of our limited funding
this year, we will not be able to send reports and 2005 questionnaires to each
program and volunteer. We are again asking for your help to notify
Despite funding cutbacks, we will continue to try to make the Dip-In more useful to you. · Please think about long term participation. We need at least 5 years or more of data on a given waterbody to calculate the transparency trends. · Last year we added an extra week to the Dip-In to accommodate more programs and individuals. Data from any part of the year is always welcome and can be added at our website. · We accept data from all sorts of turbidity instruments, not only Secchi disks, as well as temperature and pH. We welcome data taken with more than one type of turbidity instrument; we use this to correlate the instruments to produce a single value we can use for mapping. · We encourage stream and estuary programs to participate as well. · All of the data, including 2004, are now available on our website. You can retrieve it by program, by state, by county, or by waterbody. If you find errors, please let us know; you know these sites better than we do. · If you want all of the information for your program or state, please don’t hesitate to ask. It only takes us a few minutes to generate an Excel file or Access database with the information you need.
We hope that you will continue to participate this year.
