Advancement of Attachment of Biologging Tags
Abstract
Acoustic and movement tags, such as the DTAG, play a major role in ONR efforts to establish how cetaceans respond to sound in theirenvironment. Biologging acoustic tag technology has advanced rapidly over the past two decades, in large part because of ONR investment in technology development. These tags are now capable of collecting high resolution acoustic and movement data at the week scale, with successful multi-week deployments of DTAGs on pinnipeds conducted over the past five years (Mikkelsen et al. 2019; Goulet etal. 2020). For cetaceans, the latest Dtag electronics are capable of up to a week of data collection, however the average suction cup attachment duration is only 24 hours. Here we propose to focus on two areas that will be key to realizing multi-day data collection with these tags on cetaceans 1) increasing the longevity of minimally invasive tag attachments and 2) new tag attachment methods that will enable controlled and repeatable placement of tags while also enhance our ability to approach animals tagging (limits to sample size).
