Common dolphins in the Salish Sea
The appropriately named common dolphin is probably the most abundant cetacean on the planet. Common dolphins occur in most of the world’s tropical and temperate waters. Historically, they have not been common in inshore waters in Puget Sound and the Salish Sea but they are becoming more frequent as water temperatures warm.
Minke whales in the Salish Sea
Minke whales are the most abundant baleen whale species worldwide. In the waters of the west coast of North America, their populations have remained small, but stable over time. They are hunted by transient killer whales due to their relatively small size compared with other baleen whales. Sighting rates for minke whales in the Salish Sea are highest during the summer, however, little is known
Puget Sound Marine Waters 2023 Overview
Each year, the Puget Sound Ecosystem Monitoring Program releases the annual Puget Sound Marine Waters Overview report. The latest report combines a wealth of data from comprehensive monitoring programs and provides a concise summary of what was happening in Puget Sound’s marine waters during 2023. The report represents the collective effort of 67 contributors from federal, tribal, state, and local
Puget Sound researchers uncover shark secrets, but new questions arise
Recent discoveries of two new shark species in Puget Sound have sparked public interest and may encourage greater conservation efforts. In this seven-part series, Christopher Dunagan provides an overview of sharks in Puget Sound and some of the recent work among scientists to protect these often misunderstood creatures.
Discovery of soupfin shark surprises researchers
Soupfin sharks were not known to occur in Puget Sound until one was hooked by a fisherman in 2022. Scientists say warming oceans from a changing climate may be bringing more of the species into local waters. Our series on the sharks of Puget Sound continues with a closer look at soupfins and why they are being considered for inclusion on the Endangered Species List.
Is Puget Sound a nursery for sixgill sharks?
Bluntnose sixgill sharks are among the largest sharks in the world, reaching lengths of almost 16 feet. Research shows that Puget Sound may be an important place for sixgills to give birth and raise their young. We continue with part three of our series on Puget Sound's sharks.
Spiny dogfish on the move
The Pacific spiny dogfish is the most abundant shark in Puget Sound, despite its former decline due to overfishing in the 20th century. Part four of our series on sharks looks at this well-known Puget Sound resident and what is being learned about its migratory habits.
More sharks of Puget Sound
While several shark species are observed more frequently off the coast of Washington than in Puget Sound, some are seen on rare occasions in the inland waterways. Detailed information on these sharks is limited, but the same thing might have been said for sixgills, sevengills and soupfin sharks until recent discoveries opened the door to new research. Part five of our series on Puget Sound's
Fear of sharks gives way to fascination
Local shark experts say people are often surprised to find that sharks are not ruthless eating machines; rather these animals display complex social behaviors and even personalities. They say the more that people learn about sharks, the more they will want to protect them. Our series on Puget Sound's sharks continues with part six of seven.
Shark fishing raises questions about the need for more protection
In the final installment of our series on sharks in Puget Sound, we look at how fishing regulations have changed to protect potentially vulnerable shark species. Experts say more regulations may be needed as research evolves.
