Plug the power cord on the AC power supply into the DC connector on the back of the speaker. Plug the AC power supply into a live AC (mains) outlet. The speaker emits a tone to confirm connection to AC power, and charging begins. On the front of the speaker, the battery status indicator blinks yellow to show the battery is charging.
This Landsat satellite image shows Bering Glacier in Alaska, the largest glacier in North America. Although the glacier has been retreating and thinning recently, it still surges about every 20 years or so. âCredit: NASA image by Robert Simmon, based on data provided by the Landsat 7 Science Team.
Interdisciplinary Science at the Bering Glacier. The Bering Glacier is the largest and longest glacier in continental North America and is the largest temperate surging glacier on earth. The Bering Glacier has surged at least six times during the twentieth century, and the last surge occurred in 1993-1995. The Glacier is currently retreating, and scientists from MTRI have been conducting research at the Glacier during a period spanning almost a decade.
