Not only that, it’s rising faster over time. Scientists use computer models to predict how it will change in the future. But “I look more to the past,” Piecuch says. “What’s happened over the past few decades or the past few centuries.”.

- Seal Whiskers Inspire Marine Technology – Woods Hole Oceanographic ...Heather Beem is closely examining seal whiskers for insights to design new undersea technology. (New England Aquarium; inset: Heather Beem, Woods Hole Oceanographic Institution) Like many other animals, seals can use their whiskers to touch objects to determine their size, shape, and distance away.
- The value of iron for a seal - Woods Hole Oceanographic InstitutionThe first step is to determine how much iron is in the adult seals’ diets and how that changes throughout the year. Gray seals catch and eat a variety of fishes, crustaceans, and squid, all of which have different amounts of iron. The seals’ whiskers act as a sort of dietary timeline, incorporating molecular signatures from various food ...
- Seal Spy - Woods Hole Oceanographic InstitutionA 3D model of gray seals, shown here, enables scientists to take body mass measurements of each animal (example outlined in green). (Photo by Michelle Shero, Woods Hole Oceanographic Institution) “The seals act as environmental sentinels – or a canary in the coal mine for our oceans,” said Shero, “Everything from nutrients to fish ...
