Sea surface temperature (SST) is a critical control on the atmosphere(1), and numerical models of atmosphere-ocean circulation emphasize its accurate prediction. Yet many models demonstrate large, systematic biases in simulated SST in the...

Accurate estimates of mass-exchange parameters in transient storage zones are needed to better understand and quantify solute transport and dispersion in riverine systems. Currently, the predictive mean residence time relies on an empirical...

Surface transient storage (STS) and hyporheic transient storage (HTS) have functional significance in stream ecology and hydrology. Currently, tracer techniques couple STS and HTS effects on stream nutrient cycling; however, STS resides in...

Abstract: Long time series of sea surface height (SSH), sea surface temperature, and wind stress curl are used to determine the main modes of low-frequency variability of the Southern Ocean (SO) circulation. The dominant mode is a trend of...

The marine ecosystem provides a broad spectrum of services for a wide array of user groups. Such broad use of marine resources often results in use conflicts between ecosystem elements and human interests. To help mitigate these conflicts, the...

It is not unusual to see stranded or washed-up marine animals and birds along any
coastline. Various networks nationwide exist to report marine mammals and sea birds,
yet, we have been unable to find a network in Oregon or nationally to report...

Microchannels in ocean basalt glass are often attributed to the activity of microorganisms, however, neither the mechanism of formation of microchannels in glass nor the involvement of microorganisms have been confirmed by experimentation....

Euphausia pacifica, the North Pacific krill, is a key grazer in the California Current System and an important prey item for consumers such as salmon, seabirds, and whales. As a crucial link between phytoplankton and higher trophic levels, it is...

Antarctic krill are a key component of the diet of Adélie penguins inhabiting the Western
Antarctic Peninsula (WAP), yet our understanding of the variability of krill distribution
patterns within nearshore penguin feeding grounds is limited. A...

Prior to eruption at mid-ocean ridges, melts must travel through >6 km of crust from their origin in the mantle. The final composition of the melts is dependent on both the melting conditions and magmatic processes within the crust. While...

The idea of designing a new map projection via combination of two projections is well established. Some of the most
popular world map projections in use today were devised in this manner. One construction method is to combine two source...

Abstract: Tide-topography interactions dominate the transfer of tidal energy from large to small scales. At present, it is poorly understood how low-mode internal tides reflect and scatter along the continental margins. Here, the coupling...

Several acoustic Doppler current profilers and vertical strings of temperature, conductivity, and pressure sensors, deployed on and around the East Flower Garden Bank (EFGB), were used to examine surface wave effects on high-frequency flows over...

This study investigates the exchange of momentum between the atmosphere and ocean using data collected from four oceanic field experiments. Direct covariance estimates of momentum fluxes were collected in all four experiments and wind profiles...

The cause of warming in the Southern Hemisphere during the most recent deglaciation remains a matter of debate[superscript 1,2]. Hypotheses for a Northern Hemisphere trigger, through oceanic redistributions of heat, are based in part on the abrupt...

We investigated scaling of conservative solute transport using temporal moment
analysis of 98 tracer experiments (384 breakthrough curves) conducted in 44 streams
located on five continents. The experiments span 7 orders of magnitude in discharge...

We combine large observed data sets and dynamically downscaled climate data to explore historic and future (2050-2069) stream temperature changes over the topographically diverse Greater Yellowstone Ecosystem (elevation range=824-4017m). We link...

We examined the characteristics of biological patches at four different locations to assess the relationship of patch vertical scale, amplitude, and persistence. In contrast to patches of larger animals, we found that the majority of coherent...

Some amount of of consolidation has occurred under almost every individual quote program that has been implemented. In the most severe cases, fishing fleets have lost over 70% of their vessels. Because of the devastating impact such losses can...

A NE–SW-trending graben at Kap Dalton on the Blosseville Kyst contains an at least 600 m thick
succession of Eocene basalt lavas and sediments. The succession has been investigated by new field
work, geochemical analysis and radiometric dating by...
