Sedimentary Carbon

Abstract. Quantifying sedimentary carbon stocks in the coastal ocean is key to improving our understanding of long-term storage of carbon in the coastal ocean and to further constrain the global carbon cycle. Here we present a methodological approach which combines seismic geophysics and geochemical measurements to quantitatively estimate the total stock of carbon held within marine sediment. Through the application of this methodology to Loch Sunart a sea loch (fjord) on the west coast of Scotland we have created the first sedimentary carbon inventory for a fjordic system. The sediment of Loch Sunart holds 26.88 ± 0.52 Mt of carbon split between 11.05 ± 0.23 Mt and 15.02 ± 0.35 Mt of organic and inorganic carbon respectively. This quantitative estimate of carbon stored in Loch Sunart in significantly higher than previous estimates. Through comparison to Scottish peatland carbon stocks we have determined that Loch Sunart on a per are basis is a significantly more effective store of carbon. This initial work supports the concept that fjords are important environments for the burial and long-term storage of carbon and therefore should be considered as unique environments while considering coastal carbon stocks.

Abstract. Quantifying marine sedimentary carbon stocks is key to improving our understanding of long-term storage of carbon in the coastal ocean and to further constraining the global carbon cycle. Here we present a methodological approach which combines seismic geophysics and geochemical measurements to quantitatively estimate the total stock of carbon held within marine sediment. Through the application of this methodology to Loch Sunart, a fjord on the west coast of Scotland, we have generated the first full sedimentary carbon inventory for a fjordic system. The sediments of Loch Sunart hold 26.9 ± 0.5 Mt of carbon split between 11.5 ± 0.2 and 15.0 ± 0.4 Mt of organic and inorganic carbon respectively. These new quantitative estimates of carbon stored in coastal sediments are significantly higher than previous estimates. Through an area-normalised comparison to adjacent Scottish peatland carbon stocks, we have determined that these mid-latitude fjords are significantly more effective as carbon stores than their terrestrial counterparts. This initial work supports the concept that fjords are important environments for the burial and long-term storage of carbon and therefore should be considered and treated as unique environments within the global carbon cycle.

When developing information systems aimed at long-term storage of digital data, it is necessary to think over solutions that allow not only to ensure storage security, storage reliability, but also to ensure the safety of digital data in the event of a possible destabilizing effect, including a catastrophic one. That is, there is a need to ensure the stability of digital data under natural, man-made, anthropogenic or other stored influences. The first step towards digital data resilience is to assess data resilience. The aim of the work is to develop a methodological apparatus for assessing the stability of digital data in information systems operating in conditions of disasters and destabilizing factors. The article presents a methodological approach to assessing the stability of digital data, including long-term storage. The stability of digital data to destabilizing influences in the article is understood as the ability to recover in a minimum period of time both the data itself and the operability of applications responsible for the interpretation of this data, as well as the operability of other software and hardware, without which the use of digital data is not possible. The author of the article proposes a methodology for creating a mathematical model for assessing sustainability, presents a model for assessing the sustainability indicator in general. The main steps for the development of a mathematical model of stability are described. Areas of further research on the development of methodological and algorithmic apparatus for modeling the stability of digital data have been identified. The methodological approach proposed in the article can be used to solve the problems of stability of digital data of a fairly wide class of applied information systems operating in conditions of disasters and destabilizing factors. The proposed approach presupposes redundancy of software and hardware of information systems, additional time spent in the design for compiling models, additional costs for storing the "history" of the functioning of information systems, description of destabilizing factors, etc. However, according to the author of the article, this is necessary and justified to ensure the safety of valuable digital data with a long storage period.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.

The introduction and active use of information transmission and storage systems in the Ministry of Defense (MoD) of Ukraine form the need to develop ways of guaranteed removal of data from media after their use or long-term storage. Such a task is an essential component of the functioning of any information security system. The article analyzes the problems of guaranteed destruction of information on magnetic media. An overview of approaches to the guaranteed destruction of information on magnetic media of different types is presented, and partial estimates of the effectiveness of their application are given by some generally accepted indicators of performance evaluation. The article also describes the classification of methods of destruction of information depending on the influence on its medium. The results of the analysis revealed the main problems of application of software methods and methods of demagnetization of the information carrier. The issue of guaranteed destruction of information from modern SSD devices, which are actively used in the formation of new systems of information accumulation and processing, became particularly relevant in the article. In today's conditions of development of the Armed Forces of Ukraine, methods of mechanical and thermal destruction are more commonly used today. In the medium term, the vector of the use of information elimination methods will change towards the methods of physical impact by the pulsed magnetic field and the software methods that allow to store the information storage device, but this today requires specialists to develop new ways of protecting information in order to avoid its leakage.
