Arctic observations are becoming increasingly valuable as researchers investigate climate change and its associated concerns, such as decreasing sea ice and increasing ship traffic. Networks of sensors with frequent sampling capabilities are needed to run forecast models, improve navigation, and inform climate research. Sampling frequency and deployment duration are currently constrained by battery power limitations. In-situ p...

Multiplet pregnancies are rare in cetaceans, and live‐born multiple births even rarer. We used whaling data collected from pregnant females and held by the International Whaling Commission to examine multiplets in 16 cetacean species, finding that 0.87% (2,197 out of 252,651) of pregnancies included multiple fetuses, including 12 instances of five or more fetuses in five different species, all rorquals. For six species, we est...
