Degradation and release to solution of intracellular dimethylsulfoniopropionate (DMSP) from Emiliania huxleyi 370 was observed during grazing by the heterotrophic dinoflagellate Oxyrrhis marina in 24 h bottle incubations. Between 30 and 70 % of the lost algal DMSP was metabolized by the grazers without production of dimethylsulfide (DMS) when grazer...
The shallow sections of most holes drilled during Ocean Drilling Program Leg 139 contain alkenones derived from prymnesiophyte algae. The alkenones indicate a paleotemperature of the photic zone in the upper ocean during primary carbon fixation of 7°-15°C, with an average of 10.7°C. Based on laboratory hydrous pyrolyses these alkenones...
On Oregon coastal rocky shores, filter‐feeders were relatively abundant and macrophytes were relatively scarce at Strawberry Hill, whereas opposite abundance patterns occurred at Boiler Bay. To determine whether nearshore oceanographic differences were associated with these patterns, we made shore‐based measurements of nutrient and Chl a concentrations. We used a three‐level...
This paper investigates the atmospheric circulation and transport characteristics
of the Martian atmosphere (as modeled by a Mars GCM) for three sets of
conditions. The conditions are based on a combination of season and dust loading
(as parameterized by the optical depth, τ). The first experiment is for the Northern...
Eight years (1980-87) of twice-daily high-resolution radiosonde data from a tropical mid-Pacific island station are analyzed to generate time series of the planetary boundary layer (PBL) top pressure, an ageostrophic parameter (related to the divergence), and a parameter of mean PBL specific humidity. Sample spectra of these time series are...
Northeast Pacific Ocean sediments were analyzed to determine the past
relationship between northeast Pacific sea surface conditions and the climate on the
adjacent continent, the Pacific Northwest of North America. Studies of modern
ocean-atmosphere interactions demonstrate the significant effect sea surface conditions
and atmospheric circulation in the Northeast Pacific Ocean...
The wind speed and significant wave height (H1/3) dependencies of the sea state is in altimeter estimates of sea level, expressed in the form ∆hSSB=bH1/3, are examined from least squares analysis of 21 cycles of collinear TOPEX data. The bias coefficient b is found to increase in magnitude with increasing...
Field and laboratory work was undertaken in 1993 to increase understanding of the life history and ecology of the brown jellyfish,
Chrysaora fuscescens, a large semaeostome typically abundant in the neritic regions of the Oregon coast during summer months. Few
medusae were found during 1993, possibly the result of anomalous...
The BEST (Benguela Source and Transport) project was designed to investigate the form
of the Benguela Current and ratio of the Aguhlhas Current and South Atlantic Current
source waters masses. The transport of the Benguela Current and its variability was
measured by a moored array of instruments, inverted echo sounders...
This report describes current meter measurements from an experiment to measure the deep western boundary current that carries dense water from the Antarctic to the Pacific Ocean. The field measurements were conducted as part of a joint two year experiment by Oregon State University, Texas A&M University, Woods Hole Oceanographic...
An international Coupled Ocean-Atmosphere Response Experiment (COARE)
was conducted in the warm-pool region of the western equatorial Pacific Ocean over a four-month period from November 1992 through February 1993 (Webster and Lukas, 1992). Most of the oceanographic and meteorological observations were concentrated in the Intensive Flux Array (IFA) centered at...

The Alaska Coastal Management Program (ACMP) is a networked program, using existing state and local authorities and intended to allow joint state-local management of coastal zone resources and uses. The State of Alaska has outlined broad program goals, and
the local governments were to specify how those goals and additional...
Coastal communities in Oregon have experienced dramatic economic and demographic change during the 1980s. Although the timber and fishing sectors are still important, the economies of coastal communities now rely more on non-earned income and tourism. Non-earned income sources, such as transfer payments and investment earnings, account for over forty...
This paper will attempt to evaluate the prospects of the PWG's success based on
their process so far, using models of policy development and implementation from
Kingdon (1984), Putt and Springer (1989), and Sabatier and Mazmanian (1983).
Because the PWG's work is not finished, the evaluation may help the group...
The development of a Marine Pollution Monitoring Program (MPMP), in any coastal area of the world, requires a precise knowledge of the functioning of the local ecosystem. Because of the differences found in every coastal ecosystem, it is important to recognize and characterize the reservoirs and significant environments that maintain...
