Abstract:

LONG-TERM GOALS.Here we propose to make design changes to improve reliability and manufacturability of the Dtag, a sound recording multi-sensor tag. Additionally, we will set up a lease pool that will be used to provide the community with access to tags at a moderate cost per project while also allowing for monitoring of tag field performance.OBJECTIVES.Dtags have proven to be a valuable tool for the study of marine mammal acoustics and fine scale motion. The success of the Dtag has resulted in an increased demand for the instrument from researchers both within the Navy and the marine mammal community. However, the current Dtag design has cost, robustness, and reliability issues that make it unsuitable for the scaled-up manufacturing necessary to meet demand. To address this, we will improve reliability and manufacturability of the tag, and evaluate the new design by fabricating a small number of proto-type tags for testing. Additionally, this project will implement these design changes to create a pool of field-ready and cost-effective Dtags available to marine mammal researchers.
