Mobile Ocean Bottom Seismometer (MOBSI) data from Arctic rivers, lakes, and seas
We collected the data using the Mobile Ocean Bottom Seismic Instrument (MOBSI). The MOBSI is portable (9 kg) and consists of a water tight, heavy-duty pressure housing (diameter 35 cm, height 30 cm) containing a three-component, broad-band seismic sensor. There are three channels (two horizontal and...
