The Tertiary geologic evolution of the Oregon and Washington continental margin was molded by episodic periods of convergence between the Pacific oceanic plates and the North American plate. This margin is the site of a deep basin that is floored by Paleocene to lower Eocene oceanic crust and contains more...
Background. Ampelisca eschrichtii Krøyer, 1842 of the Sakhalin Shelf of the Okhotsk Sea, Far Eastern Russia, comprise the highest known biomass concentration of any amphipod population in the world and are a critically important prey source for western gray whales. Growth and reproduction in this population has not been apparent...

Despite its promise as a potentially beneficial new source of energy, the ocean-based renewable energy industry is still in its infancy, and like any new idea there are many unknowns with the potential to affect both people and our natural environments. A permit for marine renewable energy (MRE) must cut...
This document contains transcripts of Joel Hedgpeth’s series of lectures delivered over KPFA radio in Berkeley, California. These passionate lectures described the uses of oceanography, attempted to differentiate between oceanography and marine science, and encouraged students to pursue oceanography. Joel Hedgpeth was a director of the Hatfield Marine Science Center.
The goal of this thesis is to advance the methodology and thought regarding the transferability of ecological estimates of ecosystem services. Conceptually and in practice, ecological estimate transfer parallels economic benefit transfer in ecosystem services research and policy, yet the literature for benefit transfer predates ecological estimate transfer by several...
The National Park Veracruz Reef System was declared a marine protected area by the Mexican government in 1992. It contains 23 reefs presenting different degrees of environmental deterioration mainly due to the influence from nearby rivers, its proximity to the port city of Veracruz-Boca del Río and the currents patterns....
The Chiloe archipelago (Patagonia, Chile) economy lies upon agriculture, fisheries and aquaculture. The marine activities were recently affected by an epidemic crisis in salmon farming and a market crisis for most of the seafood products, including seaweeds. Two Marine Reserves (Putemun and Pullinque) in this island were also badly impacted...
