Attach the data template onto a clipboard, underwater slate or writing cylinder (see below). The Appendix has an example of the datasheet template designed for the benthic surveys. An inexpensive way to use the data template is to photocopy it onto a clear acetate overhead transparency, over which clear contact wallpaper is affixed to preserve the acetate template in the water. Then record data on semi- transparent, frosted (=single matte) plastic, mechanical drafting paper (e.g., 'Mylar') that you attach to the template with electrical tape. Or you can photocopy the data template onto both sides of white underwater paper (contact J.L. Darling Corporation, phone: 206-922-5000, fax: 206-922-5300; address: 2614 Pacific Hwy East, Tacoma, WA 98424-1017). The paper is more expensive (about $52.00 U.S./100 sheets), but data are more likely to be entered correctly since the template is reproduced on every data sheet. Use rubberbands, clips or cable ties to attach.
