Planktic foraminifers of the California Current at 42°N : last glacial maximum and present

MOCNESS plankton tows, sediment traps and sedimentary material are used to determine the linkage between bio-physical forcing and foraminiferal response over a range of time scales from the event scale to the glacial interglacial cycle. The...

Comparison of radiative feedback variability over multiple time scales in climate model...

In a steady state, the Earth's absorbed solar radiation (ASR) balances the outgoing longwave radiation (OLR) at the top of the atmosphere (TOA). In response to a radiative forcing, that is, an external perturbation to the top of the atmosphere...

Longshore grain sorting and beach-placer formation adjacent to the Columbia River

The formation of beach placers primarily involves processes of waves and currents that selectively sort and concentrate the valuable minerals according to their densities, sizes and shapes. Black sand placers are found on the beaches adjacent to...

Road networks, timber harvest, and the spread of Phytophthora root rot infestations of...

Phytophthora lateralis is the causal agent of cedar root rot, a fatal forest pathogen whose principal host is Chamaecyparis lawsoniana (Port-Orford-cedar), a predominantly riparian-restricted endemic tree species of ecological, economical, and...

The swimming behavior of the copepod Calanus marshallae under various food conditions

How certain aspects of the swimming behavior of the copepod Calanus marshallae vary as a function of different food conditions of Thalassiosira weissflogii was examined. A two video camera recording and controlled food environment aquaria system...

Development of satellite bloom detection products for coastal Oregon

Two bloom-detection products were developed for the Oregon coast that describe the relative percent change observed between successive pairs of 8-day chlorophyll-a (CHL) and fluorescence line-height (FLH) products obtained from the MODerate...

Evidence of nitric acid uptake in warm cirrus anvil clouds during the NASA TC4 campaign

Uptake ofHNO₃ onto cirrus ice may play an important role in tropospheric NOx cycling. Discrepancies between modeled and in situ measurements of gas‐phase HNO₃ in the troposphere suggest that redistribution and removal mechanisms by cirrus ice have...

Late quaternary oceanic circulation along the Pacific Coast of South America

The distribution patterns of quartz and opal contents and the distribution patterns of radiolarian assemblages, in the sediments of the southeastern Pacific, are largely controlled by both the surface winds and the mixed-layer oceanic circulation....

The structure of an arctic shallow water benthic community : effects of ice gouging

The shallow water benthic habitat of the SW Beaufort Sea is frequently gouged by the keels of ice pressure ridges. This natural physical disturbance was hypothesized to be an important factor affecting the structure of the benthic community....

Olivine-Respiring Bacteria Isolated from the Rock-Ice Interface in a Lava-Tube Cave, a...

The boundary between ice and basalt on Earth is an analog for some near-surface environments of Mars. We investigated neutrophilic iron-oxidizing microorganisms from the basalt-ice interface in a lava tube from the Oregon Cascades with perennial...

Release of dissolved organic matter by coastal diatoms

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...

Carbon Content in Oregon Tidal Wetland Soils

Tidal wetlands are a powerful carbon sink. They can sequester an order of magnitude more carbon than any other type of wetland system, and emit only negligible amounts of methane compared with freshwater wetlands (Brigham et al. 2006, Whiting and...

Geomicrobiology of marine sediment containing methane

Marine sediments contain an abundance of methane that is biologically produced and plays a significant role in the global carbon cycle. Microbes responsible for the carbon cycle in marine sediments, and the processes that they carry out, need...
