An iceberg in the Arctic Ocean. An iceberg is a piece of fresh water ice more than 15 meters (16 yards) long [1] that has broken off a glacier or an ice shelf and is floating freely in open water. [2] [3] Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits".
Sea lion attacks on humans are rare, but when humans come within approximately 2.5 meters (8 ft), it can be very unsafe. [26] In a highly unusual attack in 2007 in Western Australia, a sea lion leapt from the water and seriously mauled a 13-year-old girl surfing behind a speedboat. The sea lion appeared to be preparing for a second attack when ...
The Steller sea lion (Eumetopias jubatus), also known as Steller's sea lion or the northern sea lion, is a large, near-threatened species of sea lion, predominantly found in the coastal marine habitats of the northeast Pacific Ocean and the Pacific Northwest regions of North America, from north-central California to Oregon, Washington and British Columbia to Alaska.
A sea-lion, illustrated in A Complete Guide to Heraldry (1909). In heraldry, the term sea-lion (sometimes called a morse) [1] refers to a legendary creature that has the head and upper body of a lion, but with webbed forelimbs and a fish tail. [2] These occur most frequently as supporters, but also occur as crests and occasionally as charges. [1]
It is also a common cause of the flooding of houses when water pipes burst due to the pressure of expanding water when it freezes. [9] This iceberg can stay afloat in spite of its size because it is less dense than water. Because ice is less dense than liquid water, it floats, and this prevents bottom-up freezing of the bodies of water.
One such photo showing an iceberg that, experts say, the massive Titanic ocean liner may have likely struck before sinking to the bottom of the Atlantic, is the first one believed to be taken by a ...
The Australian sea lion (Neophoca cinerea), also known as the Australian sea-lion or Australian sealion, is a species of sea lion that is the only endemic pinniped in Australia. [2] It is currently monotypic in the genus Neophoca , with the extinct Pleistocene New Zealand sea lion Neophoca palatina the only known congener. [ 3 ]
Drifting sea ice pressure ridges can also gouge the seabed. Seabed gouging by ice is a process that occurs when floating ice features (typically icebergs and sea ice ridges) drift into shallower areas and their keel comes into contact with the seabed. [1] [2] [3] As they keep drifting, they produce long, narrow furrows most often called gouges ...
