Here, we present a method of inferring buoyancy of Weddell seals by monitoring descent rates from 4-s time-depth data, to reveal in situ insight of their life cycle. We defined a Buoyancy Indicator Segment (BIS) as the descent rate of a dive segment created with the broken-stick method that was systematically filtered to only include characteristic nonstroking and directed travel segments while excluding lung buoyancy biases. We found that BISs predicted body condition changes in Weddell seals, being a function of dive duration, mean depth, and time-of-year. Descent rates quickened with troughs in early April due to postmolt muscle recovery, early July due to winter conditions, and early September possibly due to pregnancy. Each trough was followed by weight gain, with slowing descent rates reaching peaks in late May, early August, and late October.

Harbor seals (<i>Phoca vitulina vitulina</i>) are upper-trophic level predators belonging to the phocid family (Teilmann & Galatius, <span>2018</span>). They are commonly seen as sedentary remaining in coastal waters, although they can occasionally forage offshore in some study sites (Lesage et al., <span>2004</span>). Throughout their geographic distribution, they inhabit a wide range of habitats, relying heavily on the availability and distribution of their prey in that specific environment (Bowen & Harrison, <span>1996</span>). As a result, the harbor seal is often regarded as a generalist species with potentially individualistic foraging behavior. Many studies showed that they are benthic feeders with a diet consisting of a wide variety of prey, including various species of benthic and demersal fish, cephalopods, and crustaceans, but can occasionally forage on pelagic prey (Lesage, <span>1999</span>; Sharples et al., <span>2009</span>; Thompson, <span>1993</span>).</p><p>In the Northwest Atlantic, harbor seals are generally found in small, isolated groups (Blanchet et al., <span>2021</span>).
