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.
By far the largest of the glaciers is the Vatnajokull in southeast Iceland, with an area of 3,240 sq. mi (8,400 sq. km). The Vatnajokull glacier is equal in size to all the glaciers on the European mainland put together, and reaches a thickness of 3000 ft. (1 km).
