This paper comes from many years of hard work by lots of dedicated folks! Thrilled to be able to share this work: https://link.springer.com/article/10.1186/s40462-026-00647-901 May 2026 12:09 +0000at://did:plc:gbznpfleuyzjfu2sov5ackpg/app.bsky.feed.post/3mks3twj3us2chttps://bsky.app/profile/dasweeney.bsky.social/post/3mks3n4sl622cHad a joy presenting at ECS last week in Dundee. Lots of cool science on display being done by lots of wonderful people. Stay tuned as we are finishing up model development and will have new and improved model results shortly!01 May 2026 12:05 +0000at://did:plc:gbznpfleuyzjfu2sov5ackpg/app.bsky.feed.post/3mks3n4sl622chttps://bsky.app/profile/dasweeney.bsky.social/post/3m6zbnj6yj22gMarEcoTel has another exciting paper out on goose-beaked whales. Here we used estimates of energy expenditures from tag data to dive deeper into the physiology of these amazing deep divers. Results suggest that Ziphius run out of oxygen for a large portion of foraging dives.

These model results lay an exciting foundation for us to continue our research on this species.

We compare our algorithm with K-means or depth/duration threshold clustering methods.

These whales love foraging near the seafloor and show interesting regional variability.

It's exciting to see comparative studies like this come out in wide-scale collaborative efforts to better understand these fascinating whales!
