The cold winter always makes people feel itNatureThe magic of this season, the Yellow Sea in the north of the Shandong coastJimoAoshan Bay, T-shaped Bay and other sea areas are a spectacular scene - a large area of sea ice covers the entire sea area. These ice floes, which are more than 10 centimeters thick, are like blooming flowersThe seain the "sea."Ice flowersIt brings infinite beauty and awe to people.
Sea ice refers to the accumulation of ice in seawater, which is formed on the surface of the sea, in bays, or in the seaLakesThe surface of the water freezes due to the cold air temperatures. WhileJimoAoshan Bay, T-shaped Bay and other sea areas are affected by the impactCold spellStrongCold airseawater is quickly frozen by low temperatures at low tide, forming large areas of sea ice.
These sea ices are mainly composed of primary ice and ice skin, and are about 10 centimeters thick. Outwardly, these sea ices take on an irregular shape and cover beaches, reefs, and fishing portsDocksand other areas. The ice is covered with small holes and has a soft texture, and if you put down your feet, you will sink into the ice. As the temperature rises, the sea ice begins to melt, and the transparent sea ice blends with the seawater, making a sound as the waves push it. These ice cubes are colorful and crystal clear, as if they are in full bloomThe seaflowers.
The formation of sea ice in seawater is related to a number of factors, including air temperature, salinity and suspended solids. Seawater is less prone to freezing due to its high salinity. It is only when the temperature is extremely low and persists for a period of time that the salts in the seawater precipitate out to form sea ice. At the same time, impurities such as suspended particulates and snowflakes contained in the water are also involved in the condensation of the ice.
It is worth mentioning that the ice in sea ice is not salty because the ice is less dense than water, so the ice in the sea is also less dense, and most of the ice will float on the water. Therefore, when people taste the frozen ice of the sea, they will find that it does not have a salty taste.
For Qingdao residents who have lived by the sea for a long time, the sea ice phenomenon is a relatively novel landscape. The formation of sea ice not only brings beauty to peopleScenery, also for the lives of coastal residents andFisheriesIt had a certain impact.
First of all, the formation of sea ice makes:Fishing boatsRestricted and unable to go out to sea to fish normally, rightFishermenFishing activities bring a certain amount of trouble. It was originally planned to go to seaFishermenFind your ownFishing boatsFrozen in the sea, it became almost impossible to go to sea. At the same time, along the fishing portsDocksSurrounded by thick ice floe, it was not possible to dock and hand over cargo to the vessel normally.
Secondly, sea iceBearing capacityWeak, fluffy, and prone to cracking or melting, extreme caution is required when moving around on ice. Coastal dwellers walk on or engage in iceRecreational activitiesIt is necessary to pay attention to safety to avoid accidents. Experts advise coastal residents to avoid important activities on sea ice as much as possible to ensure personal safety.
The formation of sea ice is one of the great wonders of the cold winter monthsJimoThe presence of large areas of sea ice with a thickness of more than 10 centimeters in Aoshan Bay and T-shaped Bay has made people marvelNatureThe magic. The formation of sea ice has certain peculiarities, which are affected by factors such as air temperature, salinity and suspended solids. The appearance of sea ice for coastal dwellersFisheriesand daily life has had a certain impact, but it also brings beautiful scenery and awe to everyone. However, while admiring the sea ice, we should also pay attention to safety and avoid dangerous activities on the sea ice. Every timeNatureThe wonders of the world are worthy of our awe and admiration, and while experiencing the beauty of nature, we must also protect our own safety.
