Abstract Acoustic waves with periods of 2–4 min and gravity 6–16 have been detected at ionospheric heights (250–350 km) using GPS total electron content measurements. The area disturbed by these the wave amplitudes associated underlying thunderstorm activity. A statistical study comparing Next Generation Weather Radar measurements acoustic in midlatitude U.S. Great Plains region was performed for time period May–July 2005. An increase amplitude is primarily large thunderstorms (mesoscale...
Abstract The delivery of surface meltwater through englacial drainage systems to the bed Greenland Ice Sheet modulates ice flow basal lubrication. Recent studies in Southeast have identified a perennial firn aquifer; however, there are few observations quantifying input or residence time water within system and it remains unknown whether can be stored solid ice. Using hourly stationary radar measurements, we present episodic subglacial ablation zone Store Glacier West Greenland. We find...
Glacial aquifers are an important source of groundwater in the United States and require accurate characterization to make informed management decisions. One parameter that is crucial for understanding movement hydraulic conductivity, K. Nuclear magnetic resonance (NMR) logging measures NMR response associated with water geological materials. By utilizing external field manipulate nuclear spins 1 H, time-varying decay magnetization measured. This method could provide effective way estimate K...
Coronal bright fronts (CBF) are large-scale wavelike disturbances in the solar corona, related to eruptions. They observed (mostly extreme ultraviolet (EUV) light) as transient of finite width, propagating away from eruption source location. Recent studies individual eruptive events have used EUV observations CBFs and metric radio type II burst show intimate connection between waves low corona coronal mass ejection (CME)-driven shocks. imaging with atmospheric assembly instrument on dynamics...
Abstract Nuclear magnetic resonance (NMR) logging is a promising method for estimating hydraulic conductivity ( K ). During the past ∼60 years, NMR has been used petroleum applications, and different models have developed deriving estimates of permeability. These involve calibration parameters whose values were determined through decades research on sandstones carbonates. We assessed use five to derive in glacial aquifers from data acquired two wells at each field sites central Wisconsin,...
An underground radio can provide a quick and effi cient way to communicate during mine or cave rescue. Many of the world's most dangerous caves are over 200 km in length 250 m deep. Rescues these take days require tremendous effort get injured safely out that often contains numerous rappels, climbs, terrain. Typical rescues use telephone wire fiber-optic cables through passages. However, running lines throughout takes significant amount time damage cave. These communication systems not be...
An increasingly difficult problem is the challenge to provide potable water for world's expanding population. Electromagnetic methods originally used locate oil can be shallow aquifers. Typically, electromagnetic studies track salinity of aquifers, but similar technology could applied detect new The potential detecting aquifers also applies mapping underground river systems as well providing more insight understanding local hydrology in certain areas. Controlled-source are relatively...
