The U.S. Atlantic pelagic longline fleet pursues highly migratory species (e.g., swordfish, tunas, and sharks) over an extensive range in the Atlantic, Gulf of Mexico, and Caribbean Sea. Because of the fleet’s diverse range and vessel characteristics, fuel can be a major component of vessel operating costs and can make...
Potential water scarcity and drought conditions are predicted in and around Eugene, Oregon due to decreased snowpack and subsequent decreased snowmelt in the Western Cascade Mountains. This phenomenon was triggered by a long-term trend of warmer winters scientifically linked to global climate change patterns (Dalton et al. 2013). Numerous stakeholders,...
As the western United States faces warmer and increasingly varied climate conditions, as well as predicted water insecurity, concerns over water quality and water availability are growing. While humans, fish, and wildlife are dependent on clean water for survival in the present, management of water resources needs to consider future...

The Toba Caldera Complex is the youngest resurgent caldera in the last 100 kyrs, formed from four overlapping eruptions starting 1.2 Myrs ago. The last caldera-forming eruption, the Youngest Toba Tuff eruption, occurred ~74 kyrs ago, emitting 2800 km3 of ash and pumice into the atmosphere and forming the caldera...
The for-hire sector plays a significant role in providing recreational fishing opportunities for Atlantic highly migratory species (HMS) such as tuna, billfish, swordfish, and sharks. Because of the high cost of equipment needed to pursue HMS, many saltwater anglers find chartering a for-hire vessel to be the only affordable alternative....
Highly migratory species (tunas, billfish, swordfish, and sharks or HMS) are pursued by a dedicated group of anglers that spend significant amounts in pursuit of these “big game” fish. From 2013 to 2016, NOAA Fisheries conducted the most comprehensive assessment of the economic impacts of HMS recreational fisheries in the...
Multi-stage delta-sigma (ΔΣ) architectures, commonly known as MASH, are the preferred choice for analog-to-digital converters (ADCs) used in broadband communication applications, where high-resolution (above 14 bits) and high-bandwidth (several MHz) performances are required. Current state-of-the-art designs are capable of as much as 5-MS/s output data rates with 90-dB SNR. However,...
This study examined the decay resistance of the pine and maple components of
wood plastic composites (WPC' s) of varying thicknesses exposed on several culture
media to wood decay fungi under laboratory conditions. The ability of malt agar extract
(MEA), potato dextrose agar (PDA), amended basal salts, sawdust (maple and...
The Klamath River Basin (KRB) is one of the most contested basins of the Western U.S. with respect to water. Multiple stakeholders, including Tribes, farmers, state and federal agencies, and environmental advocates, are in frequent conflict over water rights and water use. Removal of the four hydroelectric dams is one...
Like many areas around the globe experiencing ever-growing demand for diminishing natural resources, the south-central region of Texas is facing a wicked problem in water resource planning and sustainability. This Region includes San Antonio, the seventh largest city in the U.S. With a projected population increase over one million residents...
