Jellyfish benefit from many of the changes mankind is making to the ocean. Climate change, overfishing, nutrient runoff, the introduction of invasive species, and coastal development all promote these ancient, gelatinous creatures. Because of their familiarity to readers and affinity for degraded places in the ocean, jellyfish are used to...
In the past several years, international interest in gas hydrates in marine sediments has
increased considerably because of increasing recognition that the large volume of gas stored
in hydrates or trapped beneath them is a significant fraction of the global methane budget,
and may therefore be a source of energy...
At the submerged margins of the North Atlantic, andesitic to dacitic and basaltic volcanic rocks occur together. The silicic rocks were derived by processes requiring the presence of continental crust (crustal anatexis and/or contamination of mafic magmas) while the majority of the basaltic lavas had little or no contact with...
Multibeam sonar data was collected on Nehalem Bank, off of the Oregon Coast with the purpose of increasing the spatial resolution of our knowledge of the area and delineating seafloor habitats. The system used was the Kongsberg Simrad EM-300 operating at 30 kHz. The data set collected includes both topographic...
Cloud reflectivity is a function of cloud liquid water content and droplet number concentration. Since cloud droplets form around pre-existing aerosol particles, cloud droplet number concentration depends on the availability of particles that can serve as cloud condensation nuclei. Given constant liquid water amount, increased availability of cloud condensation nuclei...
The Columbia Basin once supported a diversity of native fishes and large runs of anadromous salmonids that sustained substantial fisheries and cultural values. Extensive land conversion, watershed disruptions, and subsequent fishery declines have led to one of the most ambitious restoration programs in the world. Progress has been made, but...
In the highly competitive animal protein market, seafood faces increasing pressure to improve and standardize product quality. While there is general consensus that quality can be improved for many seafood products, there is little agreement on the types and levels of characteristics that should define "quality." This is a fundamental...
An error in the calculation of the baroclinic pressure gradient term in the Princeton Ocean Model (POM) was identified while modeling the M₂ tidal current near its critical latitude in the southern Weddell Sea. The error arises from the present calculation of density, which involves the subtraction of a background...
Global climate change is projected to have far-ranging effects on the oceans and
marine life. In turn, fisheries will likely undergo changes in their distributions and
abundance. Coastal Alaskan communities are often highly dependent on commercial
fisheries, and as a result will likely be vulnerable to climate change. The purpose...
The 14-km long Netarts Littoral Cell, located on the northern Oregon coast, experienced episodic erosion as a result of the severe 1997-98 El Nino and 1998-99 La Nina. The erosion events led to the development of a unique partnership bridging scientists, stakeholders, and various planning agencies. To address these erosion...
