Lecture: Seawater pH Change History and Ocean Acidification

On May 9, 2012, Pro.Wei Gangjian, the researcher of Guangzhou Institute of Geochemistry CAS and member of State Key Laboratory of Isotope Geochemistry, visited ISL and did the academic exchange. Pro.WEI was invited by researcher Xiao Yingkai and researcher HAN Fengqin from Geology and Environment Laboratory of Salt Lake.
During the visit, Pro.WEI delivery a lecture about the theme of “Seawater pH Change History and Ocean Acidification” from the basic characteristics of the surface ocean pH change, the fate of coral reefs in the context of ocean pH change during ocean acidification and ocean acidification since the Industrial Revolution. XIAO Yingkai and Pro.WEI got depth discussions on scientific issues in reconstruction of seawater pH by using the coral boron isotope.
Pro.WEI concentrates his research interests on the fractionations and their mechanisms of both traditional and non-traditional stable isotopes during varied processes on earth's surface, with a specific interest in developing new methods/techniques for current existed or new isotopic systematic. The response of the isotopic systematic to climate and environmental factors is particularly investigated, and applied in researches of climatic.

The USA Oak Ridge National Laboratory Researchers Visit ISL

The USA oak ridge national laboratory researcher Wang Wei visited ISL from July 16th to 19th under the invitation of Wu Zhijian researcher.
Wang gave an academic report in four floor conference room of ISL, which named:”organic nano-material preparation and application in energy and the environment fields”. He firstly compared and analyzed the feasibility as well as relative merits of nuclear, water, electricity, geothermal, solar energy, which are the ways to solve energy and environment problems. Then, he shown and explained the latest research results of catalyst based on inorganic nanometer material, which can be used in solar energy material to solve the above problems.
His lecture involved related theory of solar energy utilization, preparation, the design of the structure analysis, performance characterization of inorganic nanomaterial, as well as the application of the components. He detailed answered the questions of the professors and students from ISL under lively and warm atmosphere.

　 (Experts visit salt lake . Photo by chemistry lab of Salt lake resource )
Respectively invited by shanshan resources Co., LTD (Hong Kong) and mining investment group of Chile, Ma Haizhou visited salt lake and enterprise of Argentina and Chile accompanied with 4 technicians in October 2010.
The world of saline lake lithium resources mainly distributed in Bolivia, Chile, Argentina. They are located in South America Andes , holding 52.46% of the world total reserve base According to statistics, the rest are in China, the United States and other countries. Important li-containning salt lakes of the world are Uyuni (Bolivia), Atacama(Chile), Hombre Muerto(Argentina) , taijnar and zabuye (China).The world's leading producer of lithium SQM(Chile), Chemtell( Germany) and FMC (United States) are all in South America, Chemetall and SQM are respectively developing in two different area of the salt lake Atacama, as well as FMC is in Argentina Hombre Muerto salt lake, their output occupied 70% of lithium global market.
During scientific expeditions in South America, Ma Haizhou successively made field trip of Atacama, Hombre Muerto, Maricunga, Cauchari and Diablillos etc 12 salt lakes, especially check drilling core, construction of salt pan and process flow. They also made communication with executives and technical person of SQM, Lithium Americas Corp. (LAC) and Rodinia Minerals Inc.
They got a lot of perceptual knowledge of the formation and evolution and sedimentary characteristics of South America salt lake through the investigation, deepen the understanding of development and mining process of world-class lithium resource ,which made a great significance for ISL to participate in the research of South America salt lake ,explore suitable chemical way and develop new research field.

UCLA Professors Visit ISL

(Prof. Madsen giving a lecture. Photo/RCL)
US professors, David B. Madsen, David Rhode and P. Jeffrey Brantingham, as well as their three postgraduates, from University of California at Los Angeles (UCLA) visited ISL for an exchange lasted from 12th June to 9th July 2010, at the Invitation of Research Prof. LAI Zhongping.
Profs. Rhode, Madsen and Brantingham, together with Dr. HOU Guangliang, from the Department of Geography Qinghai Normal University, respectively gave four lectures, titled (1) Packrats, Pollen and Pine I: Midden Evidence for Vegetation History in Northwest Colorado, (2) Packrats, Pollen and Pine II: The Flat Tops Pollen Records and Implications for Regional Millennial-scale Climate Cycles, (3) Did Modern Humans Evolve in China, and (4) The Relationship Between Environmental Evolution and Prehistoric Culture of Eastern Qinghai.
In his report, Rhode recounted that there still retained some packrats animal lairs since the Holocene Epoch in caves of Colorado, United States, in which the animal dung and plant tungguls that animals left when they nested their grounds glued together and were reserved till now. Through the chemical dating of the plant tungguls and the analyzing of the sporopollens, we can find out the evolutionary process of vegetation from different periods and areas, and its space migration, as well as the relation with the climate.
Madsen told about the record of sporopollens uncovered in the drillhole cores of Grizzly Lake at Colorado. Based on the varying ratio between land spruce and pine sporopollens, the regional vegetation and climatic evolutions in a scale of thousand years and scale of thousand years in the region since the Holocene Epoch were recreated.
Brantingham narrated the evolution of modern Chinese people and analyzed the evolutionary process of human from the aspect of gene and archaeology, including chronology and morphological features of stoneware.

Hou Guangliang gave an account of the relation between environmental evolution and the prehistoric culture of the east of Qinghai. He concluded that the cold climate event happened about 4000 years ago had changed the culture of eastern Qinghai: (1) the prehistoric culture decayed and shrank to the southeast; (2) the mode of production began to change; (3) the society disintegrated and marched toward multicultures. The audience includes some research staffs and students of ISL, and postgraduates from Northwest Institute of Plateau Biology, CAS and Qinghai Normal University (QHNU).
The US visitors, Dr. Hou and some members of Prof. Lai's research group made a joint investigation at Qinghai Lake and Qaidam Basin.
