Roundtable Discussion Descriptions

Telemetry Techniques and Analyses in Sea Lion Research: What Is the State of the Art?
Session leaders: Mary-Anne Lea & Mike Rehberg
Email: lea@zoology.ubc.ca and michael_rehberg@fishgame.state.ak.us

There are numerous telemetry-based studies under way of the various sea lions of the world. The purpose of this brief meeting is to bring together workers currently using—or otherwise interested in—field-deployed telemetry devices to study sea lion behavior. Although there will be no formal presentations, participants are encouraged to share their study questions, to describe the type of behavior-recording technologies and analytical techniques they are using to address questions, and to highlight the particular strengths and weakness of the techniques being used. A summary table containing this information, along with contact information for each participant, will be published in the conference proceedings and distributed by email.

Telemetry Attachment Techniques: What Works and What Doesn't?
Session leaders: Mary-Anne Lea & Mike Rehberg
Email: lea@zoology.ubc.ca and michael_rehberg@fishgame.state.ak.us

Many pinniped scientists around the world now have considerable expertise in deploying telemetry devices on otariids. This workshop is a chance for those involved in sea lion telemetry studies (past, present, or future) to share details on the successes and failures of various device attachment techniques and tag placements. Although there will be no formal presentations, workshop participants might like to bring data on the types of epoxy used, effects of tag placement, and the success of various antenna types. PowerPoint photographs of various attachment techniques and their outcomes would also help facilitate discussion. A summary table detailing the types of attachments and tag placements employed for the various species and their success will be compiled for the proceedings and emailed to workshop participants.

This symposium and proceedings result in part from outreach and communications funds from the National Oceanic and Atmospheric Administration Office of Oceanic and Atmospheric Research, Department of Commerce, under grant no.NA16RG2830 awarded to the Alaska Sea Grant College Program by the National Sea Grant Office.
