Scientists Compile First Global Inventory of Subglacial Lakes

Global inventory of subglacial lakes: (a) inventory of northern hemisphere subglacial lakes (SGLs); the top right inset shows the location of part a (red box) in the northern hemisphere; (b) inventory of SGLs beneath the Antarctic Ice Sheet; the extents of larger lakes (such as PEL Lake and Lake Vostok) are defined by blue polygons; red circles represent stable lakes identified from radio-echo sounding (RES), and blue triangles represent active lakes that have been observed to drain at least once during the observation period; lakes labeled in green have been accessed and cleanly sampled with the exception of Glacier de Tête Rousse, which was monitored using boreholes (water level) and sonar (cavity geometry), and Lake Vostok.

Scanning electron microscopy image of a nanopatterned YBa2Cu3O7−δ (YBCO) thin film. The 12-nm-thick nanopatterned YBCO thin film was fabricated by reactive ion etching through an anodic aluminium oxide (AAO) membrane directly placed atop the YBCO. By RIE, the anodized aluminium oxide pattern of a triangular array of holes with ~70-nm diameter and ~103-nm period was duplicated onto the YBCO film.

Study area and hybrid-frequency waveform earthquakes (EHWs): (a) hydraulic fracturing activity and seismicity in northeast British Columbia, Canada; the top-right inset shows the geographic location of the study area (red rectangle); blue diamonds: hydraulic fracturing injection wells between January 1, 2014 and December 31, 2016, reported by the British Columbia Oil and Gas Commission; yellow dots: earthquakes during the same period; stars: 10 M 4-5 earthquakes since 2008; black rectangle: study area in which EHWs occurred; (b, c) comparison between representative examples of a typical induced event (black trace) and an EHW (purple trace); both waveforms are from the vertical component of station MG03 with comparable source-station distance (1.32 km vs. 1.65 km) and magnitudes (MW1.5); manually picked P/S-arrivals are marked; the comparison of P/S-pulse shape demonstrates the relatively wider pulses for EHWs; (d, e) the same as (b) and (c) but for waveforms recorded at station MG02; both events show longer coda durations with slightly larger epicentral distances; note that although both types of events have extended coda durations, the EHW contains a relatively larger proportion of lower-frequency energy in the coda.
