The Vegetation Drought Response Index (VegDRI) incorporates satellite observations of vegetation to monitor at a finer spatial detail than other commonly used drought indicators.

Native Americans of the Miwok tribe in the northern Sierra Nevada, California carved these basins into the granite bedrock to produce salt for trade. They filled the basins with water from a salt spring and let the water evaporate, leaving a salt residue in the basin.

Many species of birds rely on wetlands such as this bald cypress swamp, one of the ecosystems currently being studied by scientists at the USGS NWRC.

Collecting samples (sediment, aquatic vegetation, benthic invertebrates, zooplankton, forage fish, and predatory fish) to evaluate δ 15N ratios in the food web within Liberty Bay to evaluate urbanization effects on the nearshore ecosystem. (Coastal Habitats in Puget Sound program).

USGS employees attempt to capture forage fish with the use of a Lampara net in Skagit Bay.

Honeycomb weathering of sandstone located on the shores of Puget Sound occurs when expanding salt crystals break fragments of rock, creating a small hole that becomes larger as the process repeats itself over time.

The ochre sea star is a common starfish found along the shores of Puget Sound.  This intertidal dweller feeds primarily on mussels and snails, and may live as long as twenty years.

This region contains vast areas of marshes, swamps, and barrier islands—important habitat for wildlife, as nursery grounds for marine life, and as protective buffers against storms and hurricanes.
