The currently observed Arctic warming will increase permafrost degradation followed by mineralization of formerly frozen organic matter to carbon dioxide (CO2 ) and methane (CH4 ). Despite increasing awareness of permafrost carbon vulnerability, the potential long-term formation of trace gases from thawing permafrost remains unclear. The objective of the current study is to quantify the potential long-term release of trace gases from permafrost organic matter. Therefore, Holocene and Pleistocene permafrost deposits were sampled in the Lena River Delta, Northeast Siberia. The sampled permafrost contained between 0.6% and 12.4% organic carbon. CO2 and CH4 production was measured for 1200 days in aerobic and anaerobic incubations at 4 °C. The derived fluxes were used to estimate parameters of a two pool carbon degradation model. Total CO2 production was similar in Holocene permafrost (1.3 ± 0.8 mg CO2 -C gdw(-1) aerobically, 0.25 ± 0.13 mg CO2 -C gdw(-1) anaerobically) as in 34 000-42 000-year-old Pleistocene permafrost (1.6 ± 1.2 mg CO2 -C gdw(-1) aerobically, 0.26 ± 0.10 mg CO2 -C gdw(-1) anaerobically). The main predictor for carbon mineralization was the content of organic matter. Anaerobic conditions strongly reduced carbon mineralization since only 25% of aerobically mineralized carbon was released as CO2 and CH4 in the absence of oxygen. CH4 production was low or absent in most of the Pleistocene permafrost and always started after a significant delay. After 1200 days on average 3.1% of initial carbon was mineralized to CO2 under aerobic conditions while without oxygen 0.55% were released as CO2 and 0.28% as CH4 . The calibrated carbon degradation model predicted cumulative CO2 production over a period of 100 years accounting for 15.1% (aerobic) and 1.8% (anaerobic) of initial organic carbon, which is significantly less than recent estimates. The multiyear time series from the incubation experiments helps to more reliably constrain projections of future trace gas fluxes from thawing permafrost landscapes.
There is no doubt that the digital world we are entering is not only a new logical stage in the development of the technological sphere of humanity, but also of all existing legal and socio-political realities. While common and harmonized definitions and legal definitions do not yet exist, digital technologies are already rapidly gaining ground for offensives. Digitalization is becoming a major factor in the economic growth of any country's economy. Digitization is a modern trend for the development and consistent improvement of all business processes in the economy and related social spheres, based on increasing the speed of mutual exchange, accessibility and security of information. The experts highlight eight key points of the digital economy: the state and society, marketing and advertising, finance and commerce, infrastructure and communications, media and entertainment, cybersecurity, education and human resources, startups and investments. Therefore, in determining the main goals of the digital economy can be identified: smart cities, autonomous transport, protection against cyberattacks, responsible attitude to personal data, elimination of digital inequality, telemedicine, smart agriculture, mechanisms of trust in the Internet. The implementation of any new technologies, the process, of course, is long and carries many unknown yet challenges and dangers to humanity, they are usually combined into three different groups: socio-economic, techno-organizational, natural. All this is quite fully understood in the twentieth century, introducing scientific and technological achievements in the real economy through the development of regulatory and legal factors (labor laws, environmental legislation, rules, norms, standards, practice of state and public control over their observance). The development of mass (conveyor) production of its time in general stimulated a deep study of social and legal issues of the real economy - adequate pay, a system of benefits and compensation, moral and material incentives for harmful working conditions and more. Borrowing the experience of G. Ford, we began to study the socio-psychic factors that characterize a person's attitude to work, psychological climate in the team, family, motives for work; socio-political factors for creating favorable working conditions, for invention and innovation. We have remembered that in the absence of legal rules and laws, there is always a likelihood of danger, which has become an axiom of danger, that in nature there are no phenomena absolutely safe for human life, factors - everything is dangerous and requires the formation of certain working conditions. We have also remembered that there are many examples where a lack of knowledge and a lack of methodologically based science and education justification for the practical implementation of knowledge and technology into the real economy leads to serious engineering, humanitarian and educational problems and even catastrophes. And at the same time, entering the electronic era, we are extremely light-hearted in the legal issues of defining the fundamental concepts of "information", "information resource", "information security" and more. Key words: information, informatization, information and communication technologies, information and communication security, information and communication activity, information space, information war, humanities, scientific and educational policy, information legislation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
