Dear all, We've been using TDRs for a long time in several studies in the Azores, attached with a single suction cup (design attached). Our old suction cups had a very good performance, with long attachment durations and little migration over the body. Unfortunately, we no longer have these suction cups and the Portuguese manufacturer seems to have closed. We tested some similar suction cups, but the results are disappointing. Retention times are just too short for any meaningful study. We would appreciate if any colleagues working with suction cup tags, especially but not exclusively in Europe, could give information on where you obtain your suction cups. Please write back to rcabprieto@gmail.com with the information. In the end, I will compile a list of providers, and post back here. With the very best regards from the Azores, Rui Prieto, IMAR & OKEANOS, University of the Azores MARE - Marine and Environmental Sciences Centre, FCUL 901-862 Horta Portugal Tel: (351) 292200475 Fax: (351) 292200411 Alternate e-mail: rprieto@mare-centre.pt http://whales.scienceontheweb.net
