A clean hot-water drill was used to gain access to Subglacial Lake Whillans (SLW) in late January 2013 as part of the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project. Over 3 days, we deployed an array of scientific tools through the SLW borehole: a downhole camera, a conductivity–temperature–depth (CTD) probe, a Niskin water(More)
The subduction plate interface along the Nicoya Peninsula, Costa Rica, generates damaging large (M w > 7.5) earthquakes. We present hypocenters and 3-D seismic velocity models (V P and V P /V S) calculated using simultaneous inversion of P-and S-wave arrival time data recorded from small magnitude, local earthquakes to elucidate seismogenic zone structure.(More)
Subglacial Lake Whillans (SLW) is located beneath ∼800 m of ice on the Whillans Ice Stream in West Antarctica and was sampled in January of 2013, providing the first opportunity to directly examine water and sediments from an Antarctic subglacial lake. To minimize the introduction of surface contaminants to SLW during its exploration, an access borehole was(More)
There is an ongoing debate within academic circles, and, especially as of late, public policymakers regarding the economic effects of persistent budget deficits. Macroeconomic theory suggests that if a budget deficit is not completely offset by a rise in private savings, private domestic investment or net foreign investment must decrease. A result of such(More)
