Erosion of a Sea Stack Over 100 Years

The following photographs show the demise of Jump-Off Joe, a one-hundred-foot-high sandstone formation known as a “sea stack”. In 1890, the sea stack was composed of middle Miocene concretionary sandstone of the Astoria Formation. Yaquina Head on the Horizon is composed of middle Miocene basalt flows and breccia. Note remnant of Pleistocene terrace deposit along the wave cut bench on the stack...

WFRC Ecology Section - Projects Overview

The Ecology Section examines how environmental variability, human activities and infrastructure influence food web interactions and species performance in freshwater and marine ecosystems. We have extensive experience in quantifying aquatic food web processes as they relate to growth, survival and production of key species of interest, especially resident and anadromous salmonids.

Life History of Pacific Northwest Fishes through Age and Growth Structures

The focus of our research is the ecological analysis of Pacific Northwest fishes through age and growth structures such as: scales, fin rays and otoliths (small calcium carbonate deposits beneath the brain used in hearing and balance that grow in proportion to the overall growth of the fish). These structures are utilized as research tools for understanding life histories and habitat...

Examining controls on the solubility in the ocean of iron from dust and volcanic ash- John Crusius

Biological productivity in the Gulf of Alaska is limited by availability of the micronutrient iron. Dust derived from Alaskan glacial flour and from Asian deserts, and ash from Alaskan volcanoes, episodically supply iron from the atmosphere. This internship would carry out studies on archived material from a variety of dust and ash samples to examine controls on the supply of this...

Rear-arc basalt lava outcrop

A 3-4m (10-12 ft) high outcrop of basalt lava, part of a broader lava flow. These flows were erupted about 300,000 years ago following basalt dike intrusions in a rear-arc region of northern California. The eruptions of three of these flows are thought to have taken place within several hundred years of each other.

Alder root nodules

Root nodules are a symbiotic relationship between a plant and nitrogen-fixing bacteria. A symbiotic relationship is one where both organisms benefit. Nitrogen-fixing bacteria change inorganic nitrogen from the air into ammonia, a form of nitrogen most organisms can use. They also use a process called rock dissolution to release other nutrients, such as calcium and
