Observation of Long-period Seismograph at Mizuho Camp, Antarctica

Establishment of a Long-period Seismograph Network Utilizing Magnetic Tae Recording

Investigation of Long Period Noise at Lasa

The long-period noise in the 20 to 40 second period range limits the identification level at which the surface-wave, body-wave discriminant can be anplied at the Large Aperture Seismic Array (LASA). Therefore, an investigation was made to determine die sources and properties of this noise. Only the long-period vertical array ^.t LASA was considered. Both conventional and high-resolution frequen...

UV Irradiance and Albedo at Union Glacier Camp (Antarctica): A Case Study

We report on the first spectral measurements of ultraviolet (UV) irradiance and the albedo at a Camp located in the southern Ellsworth Mountains on the broad expanse of Union Glacier (700 m altitude, 79° 46' S; 82° 52'W); about 1,000 km from the South Pole. The measurements were carried out by using a double monochromator-based spectroradiometer during a campaign (in December 2012) meant to wei...

Re-Evaluation of Geomagnetic Field Observation Data at Syowa Station, Antarctica

The Japanese Antarctic Research Expedition has conducted geomagnetic observations at Syowa Station, Antarctica, since 1966. Geomagnetic variation data measured with a fluxgate magnetometer are not absolute but are relative to a baseline and show drift. To enhance the importance of the geomagnetic data at Syowa station, therefore, it is necessary to correct the continuous variation data by using...

Outbreak of Wilderness/Backcountry/Travelers’ Diarrhea at a Himalayan Base Camp at 4000 m/13,125 ft

Introduction: Wilderness or backcountry diarrhea is a type of travelers’ diarrhea commonly caused by Cryptosporidium and Giardia, which can survive freezing temperatures. Campsites pose additional risks worldwide, irrespective of developing or developed regions, due to inadequate hygiene. Methods: In a first of its kind, an outbreak of wilderness diarrhea...
