“…9 shows the classification of icing based on the sea surface temperature of the Baltic Sea. As a result, severe and moderate icing happens when the sea surface temperature (SST) is less than +2°C and +4°C, respectively [4]. The diagram shows that severe icing mainly occurs for SST lower than +2°C and moderate icing mainly for SST lower than +4°C.…”

The paper presents results of research based on analysis of marine icing nomograms, models and charts using in the sea navigation. The problem of ships icing occurs in specific weather and geographical conditions. Every year numbers of vessels navigate in these areas meet a phenomenon of icing. Ice on decks of ships can be formed from fresh water or sea (salt) water. Ships operating in waters where the phenomime of icing is occurred use for safety navigation icing nomograms and icing charts. Icing charts are created based on icing models. The main aim of the article is to perform a review of currently used in the sea navigation icing nomograms and icing maps, based on icing models, used in navigation to depict the phenomenon of icing.

“…Limitations of nonrenewable energy sources such as oil, coal, natural gas, and uranium [2,15,16], including the high cost of exploration, exploitation, and transportation, as well as ancillary factors such as political issues [17], have resulted in concerns over energy. Additionally, burning fossil fuels for electricity generation, heating and cooling needs is deemed a major contributor to emissions of GHGs [3,[18][19][20][21][22][23].Carbon dioxide (CO 2 ) is a principal GHG agent, and new, long-residence CO 2 is being added to the atmosphere through fossil fuel use. The burning of fossil fuels has produced nearly 500 billion tons of CO 2 since the early 18th century, with almost half of it remaining in the atmosphere [6,24,25].…”

Geothermal Energy for Sustainable Food Production in Canada’s Remote Northern Communities

et al. 2019

The cold, remote, northern regions of Canada constitute a challenging environment for the provision of reliable energy and food supply to communities. A transition from fossil fuels to renewables-based sources of energy is one positive step in reducing the greenhouse gases from the energy supply system, which currently requires long-distance transport of diesel for electricity and heating needs. Geothermal energy can not only displace diesel for part of this energy need, it can provide a base-load source of local energy to support food production and mitigate adverse impacts of food insecurity on communities. In this proof-of-concept study, we highlight some potential benefits of using geothermal energy to serve Canada's northern communities. Specifically, we focus on food security and evaluate the technical and economic feasibility of producing vegetables in a "controlled environment", using ground sources of heat for energy requirements at three remote locations-Resolute Bay, Nunavut, as well as Moosonee and Pagwa in Ontario. The system is designed for geothermal district heating combined with efficient use of nutrients, water, and heat to yield a diverse crop of vegetables at an average cost up to 50% lower than the current cost of these vegetables delivered to Resolute Bay. The estimates of thermal energy requirements vary by location (e.g., they are in the range of 41 to 44 kW of thermal energy for a single greenhouse in Resolute Bay). To attain adequate system size to support the operation of such greenhouses, it is expected that up to 15% of the annually recommended servings of vegetables can be provided. Our comparative analysis of geothermal system capital costs shows significantly lower capital costs in Southern Ontario compared to Northern Canada-lower by one-third. Notwithstanding high capital costs, our study demonstrates the technical and economic feasibility of producing vegetables cost-effectively in the cold northern climate. This suggests that geothermal energy systems can supply the heat needed for greenhouse applications in remote northern regions, supplying a reliable and robust source of cost-competitive sustainable energy over the long-term and providing a basis for improved food security and economic empowerment of communities.Energies 2019, 12, 4058 2 of 25 and food insecurity, water scarcity, ocean pollution, and environmental threats, such as climate change, ozone layer depletion, acid rain, greenhouse gas (GHG) emissions, and air pollution [3,[6][7][8][9][10][11][12][13][14].

“…In addition, documented icing events required for model verification, as well as forecasting oceanographic and meteorological parameters that affect the spray-icing process, are also associated with a great deal of uncertainty. The vessel characteristics, geometry of vessel/platform-wave interactions, location of equipment and facilities on-board are other parameters that make spray ice modelling even more complex [1,3,9,15,16].Despite such challenges, some researchers have developed models to give an estimation of spray icing rate [9,[17][18][19]. However, these models have received little verification, and their complexity is, therefore, not necessarily justified by observations.…”

Marine icing is considered a major concern for vessels operating in the Arctic Ocean. Interaction between vessels and waves is the major source of sea spray that, under certain conditions, can lead to ice accretion on the vessels and thus create hazardous situations. Various models have been developed for the estimation of ice accretion rate using meteorological and oceanographic parameters. Various data sets are also available containing observations of spray icing events for different Arctic offshore regions. However, there is limited climatological information that can be used for providing decision-makers with the necessary information on optimal options and solutions in advance for assessing, managing, and mitigating the risks imposed by spray icing. In this study, a Marine-Icing model for the Norwegian Coast Guard (MINCOG) is adapted to study and analyze ice accretion on vessels operating in sea areas between Northern Norway and Spitsbergen, their temporal and spatial variations, as well as their statistical distributions over the region. This study uses NOrwegian ReAnalysis 10 km data (NORA10) of atmosphere and ocean parameters as input to the icing model from 1980 to 2012. The developed spray icing maps representing spatial and temporal variation of icing severity and spray-ice accretion rate, as well as the probability of the occurrence of icing events at different junctures and periods, can be used for risk-based decision-making tasks involved in industrial activities including shipping and offshore logistics operations in these sea areas.
