Section 2 sets a foundation for understanding the Salish Sea ecosystem by describing its fundamental biophysical processes and structure, including estuarine circulation, ecological productivity, and an overview of several important biogenic habitats.

The Salish Sea is an estuarine ecosystem. Freshwater from land drainages mixes with the waters of the Pacific Ocean and results in water with a measurable, although sometimes small amount of freshwater. The Salish Sea is among the preeminent estuaries of North America. Estuarine circulation and flow are central to the high biological productivity in the Salish Sea.

One of the primary terrestrial pressures on the Salish Sea estuarine and marine environment is urban stormwater runoff. When rainfall runs across hard, impervious surfaces, rather than soaking into the soil, it picks up and delivers toxic contaminants directly to nearby streams, rivers, and eventually the Salish Sea. In fact, for most toxic substances, surface runoff is the largest contributing source of loading to Puget Sound. Unfortunately, the Salish Sea’s relationship with stormwater effluent is no outlier; stormwater is the fastest growing cause of surface water impairment in the United States as urbanization transitions forested and other natural landscapes to …

Blue whale sound production has been thought to occur by Helmholtz resonance via air flowing from the lungs into the upper respiratory spaces. This implies that the frequency of blue whale vocalizations might be directly proportional to the size of their sound-producing organs. Here we present a sound production mechanism where the fundamental and overtone frequencies of blue whale B calls can be well modeled using a series of short-duration (<1 >s) wavelets. We propose that the likely source of these wavelets are pneumatic pulses caused by opening and closing of respiratory valves during air recirculation between the lungs and …

From 1947 to 1948, paleontologists from the University of California Museum of Paleontology (UCMP), Charles Camp and Frank Peabody, led the southern branch of the University of California’s Africa Expedition. While in South Africa, Camp and Peabody collected thousands of specimens excavated from more than 70 sites, 40 of which make up the Plio-Pleistocene South African assemblage at the UCMP. Materials collected by researchers accompanying the expedition are held at numerous repositories on the University of California Berkeley campus including the UCMP, the Museum of Vertebrate Zoology (MVZ), the Phoebe A. Hearst Museum of Anthropology and the University of California’s …
