Although oceanographers such as Roger Revelle are typically associated with key indicators
of anthropogenic change, he and other scientists at midcentury had very different
scientific priorities and ways of seeing the oceans. How can we join the narrative of the
triumph of mathematical, dynamic oceanography with the environmental narrative? Dynamic...
Mutation breeders in the 1960s seemed poised to use atomic energy to speed up mutation rates in plants in order to develop new crop varieties, for the benefit of all people. Although skepticism had slowed this work in the United States, the International Atomic Energy Agency (IAEA) nurtured the scientific...
To determine if a storm event (i.e., high winds, large volumes of precipitation) could
alter concentrations of Vibrio vulnificus and V. parahaemolyticus in aquacultured oysters
(Crassostrea virginica) and associated surface water and sediment, this study followed a
sampling timeline before and after Hurricane Irene impacted the Chesapeake Bay estuary in...
Despite limited success, today’s information retrieval (IR) systems are not intelligent and reliable. IR systems return poor search results when users formulate their information needs into incomplete or ambiguous queries (i.e., weak queries). Therefore, one of the main challenges in modern IR research is to provide consistent results across all...

This study was performed in response to doubts about the reliability of the database in place at ODFW. It consisted of surveys to verify if Chinook salmon were using the habitats previously identified and looks for discrepancies between summer habitat inventory and fall Chinook spawners. A large portion of the...
Microbial communities are responsible for the bulk of biogeochemical processing in temporary headwater streams, yet there is still relatively little known about how community structure and function respond to periodic drying. Moreover, the ability to sample temporary habitats can be a logistical challenge due to the limited capability to measure...
Vibrio vulnificus and Vibrio parahaemolyticus are ubiquitous in the marine–estuarine environment, but the magnitude of human non-ingestion exposure to these waterborne pathogens is largely unknown. We evaluated the magnitude of dermal exposure to V. vulnificus and V. parahaemolyticus among swimmers recreating in Vibrio-populated waters by conducting swim studies at four...
Basal melting of ice shelves around Antarctica contributes to formation of Antarctic Bottom Water and can affect global sea level by altering the offshore flow of grounded ice streams and glaciers. Tides influence ice shelf basal melt rate (w(b)) by contributing to ocean mixing and mean circulation as well as...
In order to investigate how submarine weathering processes may affect the water balance of sediments at convergent plate margins, six sediment cores were retrieved off Central Chile at water depth between ∼800 and 4000 m. The sediment solid phase was analyzed for its major element composition and the pore fluids...
