Temperature anomalies can identify locations of seeps of groundwater into surface waters.
However, the method’s sensitivity to details such as thermometer burial depth, sediment material, seep
velocity, and surface water current are largely unknown. We report on a series of laboratory flume experiments
in which controlled seeps under variable sediment...

Error in Distributed Temperature Sensor (DTS) water temperature measurements may
be introduced by contact of the fiber optic cable sensor with bed materials (e.g.,
seafloor, lakebed, stream bed). Heat conduction from the bed materials can affect cable
temperature and the resulting DTS measurements. In the Middle Fork John Day River,...

We apply GENMOM, a coupled atmosphere–ocean climate model, to simulate eight equilibrium time
slices at 3000-year intervals for the past 21,000 years forced
by changes in Earth–Sun geometry, atmospheric greenhouse
gases (GHGs), continental ice sheets, and sea level. Simulated
global cooling during the Last Glacial Maximum
(LGM) is 3.8°C and...

Rapid Arctic warming is associated with important water cycle changes: sea ice loss, increasing atmospheric humidity, permafrost thaw, and water-induced ecosystem changes. Understanding these complex modern processes is critical to interpreting past hydrologic changes preserved in paleoclimate records and predicting future Arctic changes. Cyclones are a prevalent Arctic feature and...

Small crack fatigue is a widely recognized problem in the fatigue of materials; however, there has been limited progress in developing methods for predicting small crack fatigue behavior. In this paper, small crack effects due to crack bridging are addressed. A fatigue threshold R-curve was measured for a 99.5% pure...
