An iceberg is a very large object that can be detected in the open sea both visually and by radar. In principle an iceberg can also be detected by sonar. Because a ship may steer to avoid a large parent berg, it may be in greater danger from undetected growlers or bergy bits drifting nearby.

An iceberg is ice that broke off from glaciers or shelf ice and is floating in open water. Icebergs are also classified by shape, most commonly being either tabular or non-tabular. Tabular icebergs have steep sides and a flat top.২৬ ফেব, ২০২১

Density also explains why most of an iceberg is found beneath the ocean’s surface. Because the densities of ice and sea water are so close in value, the ice floats “low” in the water. This means that ice has nine-tenths, or 90 percent of water’s density – and so 90 percent of the iceberg is below the water’s surface.

Icebergs are thick masses of ice floating in the ocean. The reason why ice floats and is lighter than water is that a certain mass of ice occupies more space than the same mass of water. This is related to the characteristics of hydrogen bonds. This iceberg is floating off the Otago coastline.১৯ জুলাই, ২০০৭

You can’t use your feet, so you have to use your arms to pull yourself up and onto the iceberg. Q: Cold temperatures, 45-metre icebergs, one-metre swells, this sounds like a dangerous hobby. A: It is risky and there is a chance that the iceberg could collapse and if it does, we could die.১৯ এপ্রিল, ২০১২

Icebergs form when chunks of ice calve, or break off, from glaciers, ice shelves, or a larger iceberg. On the iceberg surface, warm air melts snow and ice into pools called melt ponds that can trickle through the iceberg and widen cracks.

The Amery Ice Shelf in Antarctica has just produced its biggest iceberg in more than 50 years. The calved block covers 1,636 sq km in area – a little smaller than Scotland’s Isle of Skye – and is called D28.৩০ সেপ্টেম্বর, ২০১৯

Titanic struck a North Atlantic iceberg at 11:40 PM in the evening of 14 April 1912 at a speed of 20.5 knots (23.6 MPH). The berg scraped along the starboard or right side of the hull below the waterline, slicing open the hull between five of the adjacent watertight compartments.

Icebergs may reach a height of more than 100 metres (300 ft) above the sea surface, and have mass ranging from about 100,000 tonnes up to more than 10 million tonnes.

Iceberg B-15 was the largest recorded iceberg by area. It measured around 295 kilometres (183 mi) long and 37 kilometres (23 mi) wide, with a surface area of 11,000 square kilometres (4,200 sq mi)—larger than the whole island of Jamaica.

Lurking iceberg. But sometimes in stormy weather or as an iceberg cleaves from the glacier—a process called “calving”—it flips. Or, as an iceberg drifts into warmer seas, the melting of its massive underbelly can throw it off balance, upending it.২৬ জানু, ২০১৫

Sometimes you can smell an iceberg before you see it. As the ice melts, minerals give off an odor. It’s hard to tell the size of an iceberg because 90 percent of it is underwater.১২ এপ্রিল, ২০১২

According to the U.S. committee investigating the sinking, 1,517 lives were lost, and its British counterpart determined that 1,503 died. The crew suffered the most casualties, with about 700 fatalities. Third class also suffered greatly, as only 174 of its approximately 710 passengers survived.৯ এপ্রিল, ২০২১
