The ST-6 SLTDRs were on 24 h/day and transmitted a maximum of 400 transmissions/day.
Trip duration was measured for 10 of 25 animals with SDRs containing time-line data (it was not possible to calculate trip duration for 15 SDRs with the earlier SLTDRs that did not transmit time-line data).
In another study, adult females in Alaska were equipped with early-style SLTDRs that had features that recorded time-depth information and these SLTDRs showed that the females frequently dived to 200 m or more (Merrick et al.
5), and 10 min later, the whale rejoined a group milling nearby (see Appendix for further details of SLTDR attachment).
Preliminary results from SLTDR data for this animal suggest that belugas remain in the upper inlet over much of the summer (Fig.
In upper Cook Inlet, three seasons of learning were required before a SLTDR was successfully attached in 1999.
