This differential, which had not been scientifically investigated until recently, has a large effect on the rate of ice melting and the extent of ice cover. [1] Melt ponds can melt through to the ocean's surface. [2] Seawater entering the pond increases the melt rate because the salty water of the ocean is warmer than the fresh water of the pond.
Clear blue ice tends to be stronger than cloudy ice as it indicates the calmness of the water underneath. Calmer water equals better ice. If the ice is gray or slushy looking it should be ...
The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron, and Walter Findeisen []), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation vapor pressure over water and the lower saturation vapor pressure over ice.
Meltwater (or melt water) is water released by the melting of snow or ice, including glacial ice, tabular icebergs and ice shelves over oceans. Meltwater is often found during early spring when snow packs and frozen rivers melt with rising temperatures, and in the ablation zone of glaciers where the rate of snow cover is reducing.
Natural events such as landslides or the slow melting of a frozen moraine can incite drainage of a supraglacial lake, creating a glacial lake outburst flood. In such a flood, the lake water releases rushes down a valley. These events are sudden and catastrophic and thus provide little warning to people who live downstream, in the path of the water.
The movement of the water is influenced and directed by gravity and the melting of ice. [1] The melting of ice forms different types of glacial streams such as supraglacial, englacial, subglacial and proglacial streams. [1] Water enters supraglacial streams that sit at the top of the glacier via filtering through snow in the accumulation zone ...
The pond, which is approximately one foot deep, is composed almost entirely of fresh water melted from the ice beneath. [1] [3] A web camera is stationed beside the pond to monitor changes. It was built by the Polar Science Center. [1] On July 26, 2013, the depth was estimated to be approximately 40 cm. [1]
It's common for kids to have a meltdown after school. Here's why it happens — and how to handle it in the moment, according to experts.
