Coastal foredunes protect lives, infrastructure, and ecosystems during severe winter storms. In the U.S. Pacific Northwest (PNW), coastal foredune geomorphology is determined by both physical and ecological mechanisms. Before the 1900's, the native plant Elymus mollis was the dominant dune grass and dune morphology was largely determined by sediment supply...
Meteorological conditions during an intensive oceanographic observational program
in May through August 2001 along the central Oregon coast are described and related to
larger-scale and longer-term conditions. Southward wind stresses of 0.05-0.1 N m⁻²
occurred roughly 75% of the time, with a sustained period of dominantly southward stress
from mid-June...
Mangroves are becoming increasingly recognized as important nursery habitats for many juvenile fish and macroinvertebrate species, however little is known about their importance for zooplankton communities. The complex structure of mangrove environments may provide zooplankton populations with shelter, substrate, food, and protection from depredation. These factors could impact zooplankton survival,...

different coastal habitats. This project is composed of two studies conducted in red mangrove communities
The purpose of the Oregon Coastal and Marine Data Network Workshop was to begin to set the stage for fostering a network of people and data. The workshop was designed to enable individuals in agencies and other organizations who are directly engaged in coastal marine spatial planning to discuss and...
Hazards threaten coastal communities and ecosystems over a wide range of spatiotemporal scales. One of the most pressing concerns for coastal property owners, decision makers, and researchers is the uncertain role that a changing climate will have on the intensity and frequency of these hazards. The significant uncertainties associated with...

Les graves atteintes aux équilibres des écosystèmes côtiers et littoraux sont devenues une préoccupation partagée par les chercheurs et les développeurs. La détérioration du bien-être des populations gui en sont soit la cause, soit la conséquence, impose la révision du discours économique prédominant dans les programmes de développement. L'impératif de...
Wind-driven coastal ocean upwelling supplies nutrients to the
euphotic zone near the coast. Nutrients fuel the growth of phytoplankton,
the base of a very productive coastal marine ecosystem
[Pauly D, Christensen V (1995) Nature 374:255–257]. Because
nutrient supply and phytoplankton biomass in shelf waters are
highly sensitive to variation in...
The debate over a coastal migration route for the First Americans revolves around two major points: seafaring technology, and a viable landscape and resource base. Three lake cores from Sanak Island in the western Gulf of Alaska yield the first radiocarbon ages from the continental shelf of the Northeast Pacific...
Dissolved organic matter (DOM) production was examined in axenic batch cultures of five coastal diatom species. For Chaetoceros decipiens, dissolved organic carbon (DOC) accumulated beginning in late exponential growth as a result of increased cell density. For Cylindrotheca closterium, DOC actually decreased in late exponential growth and reached zero by...
