The "oasis" of deep-sea life, the first whale drop in the South China Sea, less than 50 modern natural whales

Whale falls are ecosystems formed by whales falling into the deep sea after their death, and are known as "oasiss" of deep-sea life along with hydrothermal and cold springsChinese scientists have found whales in the South China Sea for the first timeYesterday, the Chinese Academy of Sciences "Exploration One" ship aboard the "Deep Sea Warrior" manned submersible successfully arrived in SanyaOne of the key achievements of the voyage, which began on March 10, was the first time scientists had discovered a whale drop about 3 meters long in the South China SeaWhale falls are ecosystems formed by whales falling into the deep sea after their death, and are known as "oasiss" of deep-sea life along with hydrothermal and cold springsExperts say that the current international discovery of modern natural whales fell less than 50, the whale fall has long-term observational valueOn the afternoon of April 2, , the Chinese Academy of Sciences "Exploration One" ship carrying the "Deep Sea Warrior" manned submersible, in 22 days, carried out 22 consecutive deep dives, completed the voyage science and technology mission, and successfully arrived in Sanyaat 3 p.mon the 2nd, "Discovery One" carrying 60 members of the scientific examination team successfully returned homeThe voyage began on March 10 with the completion of the Southern Ocean Laboratory-supported project "Key Processes and Drive mechanisms for typical seamount ecosystems in the western Pacific"One of the important achievements of the voyage was the first discovery of a whale landing about 3 meters long in the South China Sea, which refers to the ecosystem formed by the whale's death and falls into the deep sea, known along with hydrothermal and cold springs as an oasis of deep-sea lifeThis is the first time that our scientists have discovered this type of ecosystemTS16 voyage co-chief scientist Sun Yat-sen University Associate Professor Xie Wei: At present, less than 50 modern natural whales found in the world, these whales fall according to their degradation status and community structure, can be divided into three periods, mobile scavenger stage, opportunist stage, chemical self-cultivation stageThe South China Sea whale fell, the tail can still be observed with thefish tearing muscles, indicating that it is still in the first stage, possibly a dead whale, with long-term observational valuediscovery is of great significance for us to understand how marine ecosystems sustain deep-sea life and the conservation and utilization of deep-sea biodiversity resources in ChinaTS16 voyage co-chief scientist Sun Yat-sen University Associate Professor Xie Wei: Deep-sea life is usually in a poor food condition, a whale death, will quickly sink to the bottom of the sea, the nutrients to the deep sea, become an oasis of deep-sea life, breeding a rich and diverse liferecently, we Chinese scientists completed the first whale scientific expedition in the South China Sea, the harvest is very rich! Follow this tweet and experience what's gaining from this "whale" happy trip to the bottom of the South China Sea!first to master the basic small file of this scientific examination:the name of the science examination project: "South China Sea deep diving whale science examination voyage"purpose: to understand the current situation of deep diving and distant whale resources in the seasignificance: for the future further in-depth research on deep diving whales in the South China Sea, the formulation of appropriate ecological conservation measures and The development of the whale conservation development industry and otherparticipants in the development of scientific support: 16 scientists from the Marine Mammal Research Team of the Institute of Deep Sea Science and Engineering of the Chinese Academy of Sciencesthe voyage: a total of 14 days of sea exploration, a total range of about 2,500 km;time: May 10 from the South China Sea back to Sanyait is worth mentioning that this expedition is china's first in the corresponding waters in the South China Sea to carry out deep diving and distant whale scientific investigation, previously recorded China's whales of relatively few professional scientific research data, some of the information only from stranded cetaceansLet's take a look at the major gains of this expedition:team found a large number of cetaceans in the northern waters of the South China Sea, of which four species of deep-dive cetaceans can be identified, namely:sperm whales, Keshce, short-legged pilot whales, patterned whales (Reis dolphins)distant dolphin species 3 species, respectively:tropical spotted dolphins, striped dolphins, fudolphinsand 2 other species to be further identified(small make up good curiosity these 2 species is what ah! When we have new news will tell you the first time, please continue to pay attention to our South China Sea Voice son ha advertising end) to listen to what scientists say: the Chinese Academy of Sciences Institute of Deep Sea Science and Engineering Associate Researcher Lin Mingli: "the results of this expedition exceeded expectations, we found through this expedition, six of the seven species are the first time in the South China Sea field visit found, whale resources rich." other animal groups, with the exception of tropical spotted dolphins, are the first discoveries and records of researchers in the sea surveyed, , sperm whales and moths have observed mother-to-child pairs, indicating that there is a high probability of the presence of sperm whales and moths in the northern survey waters of the South China Sea South China Sea fishing nets and garbage and other threats to the survival of whales are distressing li Songhai, a researcher at the Institute of Deep Sea Science and Engineering of the Chinese Academy of Sciences, said: also found a lot of fishing nets in the course of the expedition, there is a lot of garbage on the surface of the water, the next step we have to find a way to make our environment better, so that these animals can better survive here, the population can continue to grow South China Sea Voice here calls on all sectors of the community to pay attention to the living environment of marine life such as whales, do not throw garbage into the ocean ah friends!
