Simulation of submarine groundwater discharge salinity and temperature variations: Implications for remote detection Simulation of submarine groundwater discharge salinity and temperature variations: Implications for remote detection

A hydrological analysis using a numerical simulation was done to identify the transient response of the salinity and temperature of submarine groundwater discharge (SGD) and utilize the results to guide data collection. Results indicate that the amount of SGD fluctuates depending on the ocean stage and geology, with the greatest amount of SGD delivered at low tide when the aquifer is in...

Size-based trends and management implications of microhabitat utilization by Brown Treesnakes, with an emphasis on juvenile snakes Size-based trends and management implications of microhabitat utilization by Brown Treesnakes, with an emphasis on juvenile snakes

The brown treesnake (Boiga irregularis, or BTS), a costly invasive species, has been the subject of intensive research on Guam over the past two decades. The behavior and habitat use of hatchling and juvenile snakes, however, remain largely unknown. We used a long-term dataset of BTS captures (N = 2,415) and a dataset resulting from intensive sampling within and immediately around a 5-ha...

Temporal variability of submarine groundwater discharge: Assessments via radon and seep meters, the southern carmel coast, Israel Temporal variability of submarine groundwater discharge: Assessments via radon and seep meters, the southern carmel coast, Israel

Seep meter data from Dor Bay, Israel, showed a steady decrease in submarine groundwater discharge (SGD) rates between March and July 2006 (averages of 34, 10.4 and 1.5 cm d-1 in March, May and July, respectively), while estimates based on radon time series showed remarkably uniform averages (8 cm d-1). The May seep meter data show a rough positive correlation with sea level, unlike the...

TerraLook: Providing easy, no-cost access to satellite images for busy people and the technologically disinclined TerraLook: Providing easy, no-cost access to satellite images for busy people and the technologically disinclined

Access to satellite images has been largely limited to communities with specialized tools and expertise, even though images could also benefit other communities. This situation has resulted in underutilization of the data. TerraLook, which consists of collections of georeferenced JPEG images and an open source toolkit to use them, makes satellite images available to those lacking...

The 3D fault and vein architecture of strike-slip releasing- and restraining bends: Evidence from volcanic-centre-relatedmineral deposits The 3D fault and vein architecture of strike-slip releasing- and restraining bends: Evidence from volcanic-centre-relatedmineral deposits

High-temperature, volcanic-centre-related hydrothermal systems involve large fluid-flow volumes and are observed to have high discharge rates in the order of 100-400 kg/s. The flows and discharge occur predominantly on networks of critically stressed fractures. The coupling of hydrothermal fluid flow with deformation produces the volumes of veins found in epithermal mineral deposits...
