This overview discusses the processes that control ocean and climate characteristics. Topics include atmospheric forcing, precipitation patterns, oscillation trends, coastal upwelling, and climate change.

When rivers spill into Puget Sound, they provide some of the most productive habitat in the ecosystem. The ebb and flow of the tides creates a perfect mix of fresh and salt water critical for young salmon. But over the past 100 years, the region’s tidal wetlands have declined by more than 75%. Now a coalition of state and federal agencies has a plan to bring them back.

Zooplankton are critical to the marine food web, but until recently there have been few surveys of the zooplankton community in Puget Sound. Ongoing monitoring is now revealing a system full of complexity and surprises. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.

The history of land use in King County has produced a lowland and foothill landscape of bewildering variety. The once continuous forest of western hemlock, Douglas-fir, and redcedar has given way to a patchwork of lawns, parks, playgrounds, woodlots, greenbelts, old fields, croplands, tree farms, and remnant forests set amid a landscape of urban, suburban, rural, and commercial uses, ...

The following article describes how both adult and juvenile coastal cutthroat trout use estuaries in Puget Sound and includes text from two previously published overviews on the subject by University of Washington biologist Thomas P. Quinn.

This report discusses lessons learned from the task of choosing near term actions (NTAs), activities and initiatives for achieving recovery targets for Puget Sound Vital Sign indicators. It focuses on efforts by Local Integrating Organizations in Island County, including Whidbey and Camano Islands. 

This report, Priority science for restoring and protecting Puget Sound: a Biennial Science Work Plan for 2011-2013, identifies priority science and monitoring questions needed to coordinate and implement effective recovery and protection strategies for Puget Sound.

Puget Sound's rockfish have declined by 70% over the past few decades, prompting state and federal protection efforts. We look at some of the ways that scientists are working to reverse the fish's downward trend. 

Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) are underwater robotic vehicles used for a variety of ocean surveys and operations. Both are used for deep-sea observation, mapping of underwater environments, and surveys of biodiversity and water quality trends. While ROVs are tethered to the user by a cord called the umbilical, which provides power as well as control and video signals, AUVs are programmed for a specific course and then set loose, operating without a tether.
