Louise Round, a marine animal medic, explained that “seal finger” is caused by the necrotic bacteria on their teeth. She said: “It’s a really nasty blood infection, it’s horrible. It ...
Seal finger was first described scientifically in 1907. [4] [5] It can cause cellulitis, joint inflammation, and swelling of the bone marrow; untreated, the course of "seal finger" is slow and often results in a thickened, contracted joint. [3] Historically, seal finger was treated by amputation of the affected digits once they became unusable.
Breaking swell waves at Hermosa Beach, California. A swell, also sometimes referred to as ground swell, in the context of an ocean, sea or lake, is a series of mechanical waves that propagate along the interface between water and air under the predominating influence of gravity, and thus are often referred to as surface gravity waves.
Here's why your fingers get swollen sometimes. Even healthy moves like walking can leave your fingers swollen. Usually, it's nothing to worry about. Here's why your fingers get swollen sometimes.
It has also been called depth intoxication, “narks,” and rapture of the deep. It can cause a decrease in the diver's ability to make judgements or calculations. It can also decrease motor skills, and worsen performance in tasks requiring manual dexterity. [10] As depth increases, so does the pressure and hence the severity of the narcosis.
When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. [1] The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp ...
The brine-rich water remains liquid, and its increased density causes this water to sink, setting the stage for the creation of a "brinicle". Its outer edges begin accumulating a layer of ice as the surrounding water, cooled by this jet to below its freezing point, ices up in a tubular or finger shape and becomes self-sustaining.
A recent research focused on the causes of Kallakkadal events [2] has established the link between North Indian Ocean high swell events and the meteorological conditions in the Southern Ocean using a combination of ocean wave observations and numerical model simulations. The study confirms that Kallakkadal events are caused by swells ...
