Rotifers and brine shrimp (Artemia) are important prey items for rearing marine fish larvae. Their availability in the water column may be reduced when they are transferred to larval rearing tanks at lower temperature. In this study, Brachionus rotundiformis (SS-type) and Brachionus plicatilis (L-type) were semi-continuously cultured and fed on...

The Middle Fork of the John Day River (MFJD) in Northeastern Oregon contains important spawning grounds for spring Chinook and summer steelhead of the Columbia River Basin. In the summer of 2008 phase one of a river restoration project was completed which included the addition of engineered log jams (ELJs)...

Title: Monitoring River Restoration using Fiber Optic Temperature Measurements in a
Modeling Framework
Multiple use of waste heat from power plants may become an important consideration in their development and siting. The heat in the cooling water must be considered a resource to be managed for effective use. Soil warming was suggested as one of several possible productive uses for the heated discharges....

The hyporheic zone influences the thermal regime of rivers, buffering temperature by storing and releasing heat over a range of timescales. We examined the relationship between hyporheic exchange and temperature along a 24-km reach of the lower Clackamas River, a large gravel-bed river in northwestern Oregon (median discharge = 75.7...

The Metolius River basin is a sub-basin of the Deschutes Basin within central Oregon. Considered one of the crown jewels of the state, this historically undisturbed basin drew attention in 2009 because the Oregon legislature designated the basin as the first Area of Critical State Concern (ACSC) under the state’s...
As part of a larger study to examine the effect of climate change (CC) on estuarine resources, we simulated the effect of rising sea level, alterations in river discharge, and increasing atmospheric temperatures on water quality in the Yaquina Estuary. Due to uncertainty in the effects of climate change, initial...
Global warming is expected to affect the ecosystem in the Northeast Atlantic, and sufficient changes will also affect
the aquaculture industry. Farming of salmon and trout is the biggest aquaculture industry in Norway. The export
value was about 2 billion US dollars in 2005. The objective of the paper is...
Eighteen-hundred grand fir (Abies grandis) studs, curve sawn from small-diameter [approximately 4-7 inches (102-178 mm)] sawlogs, were kiln dried to determine effects
of drying schedule and restraint on energy consumption, drying time, and warp (bow,
crook, and twist). The experimental design included 18 kiln charges with three replications
of three...

The Aucanquilcha Volcanic Cluster (AVC) is the erupted part of a magmatic system with a complex and long-lived history. The AVC lies at 21°S in the high Andes and is built on thick continental crust. The thick crust in the area combined with the prolonged magmatic activity make it an...

Wecoma cruise W8705A was conducted in May 1987 as part of the pilot study for the Coastal Transition Zone project. CTD observations were made in the coastal transition zone off northern California between 37.5°N and 41.5°N. Stations were planned along three alongshore transects, at distances of 60, 90 and 150...
Wecoma cruise W8806A was conducted in June 1988 as part of the pilot study for the Coastal Transition Zone project. CTD observations were made over a standard grid in the coastal transition zone off northern California between 37° N and 39.5° N that was to be occupied repeatedly during June,...
