Internal‐tide generation is usually predicted from local topography, surface tides, and stratification. However, internal tides are often observed to be unrelated to local spring‐neap forcing, appearing intermittently in 3–5 day bursts. Here we suggest a source of this intermittency by illustrating how remotely‐generated shoaling internal tides induce first‐order changes in...
The seafood industry in Alaska produces about 4.4 billion pounds of fish every year and approximately 2.2 billion pounds of fish waste. Product recovery rates in the seafood industry have increased in the last decade, but still a large portion of all harvested fish is unused and often discharged into...
The range of verification problems that can be solved with logic model checking tools has increased significantly in the last few decades. This increase in capability is based on algorithmic advances and new theoretical insights, but it has also benefitted from the steady increase in processing speeds and main memory...
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...
Headwater streams are an integral part of the ecological health of the greater stream network as they provide valuable biological habitat, provide upwards to 95% of total in channel flow, while providing downstream reaches with important constituents such as sediment and woody debris. Small headwater streams are particularly susceptible to...
Fractal-like branching microchannel flow networks have been found to improve wall temperature uniformity and decrease both pressure drop and flow power compared to arrays of straight microchannels. The present study seeks to maximize the benefits of fractal-like branching channels by means of a gradient-based optimization algorithm. The algorithm identifies the...
Rates of benthic O₂ exchange are important measurements for determining organic matter remineralization, and can shed light on factors driving biogeochemical processes in coastal environments. Measurement of in situ O₂ consumption and production within permeable sediments, such as those found over ~43% of the Oregon-Washington shelf, has traditionally been done...
Diseases caused by parasites are recognized as significant sources of mortality in wild fish populations. I assessed the impacts of multispecies parasitism on a threatened stock of juvenile coho salmon (Oncorhynchus kisutch). A crucial prerequisite to this research was proper identification of parasites, which can be difficult for species lacking...
Girls on the Run (GOTR) is a community-based running program that encourages social, mental, emotional and physical development in young girls through the process of training for a 5k running event. Previous reports have shown that GOTR has positive effects on self-esteem and dietary behaviors; whether GOTR influences levels of...
The use of Ionization Chambers and Thermo-luminescent dosimeters (TLD's) in the medical field has established a need to determine if the skin depth dose response is comparable between the two detectors. This research will determine if the dose response from an Ionization chamber is comparable to a Thermo-luminescent dosimeter system...
