The ash content was highest in Cystoseira Barbata (19.20%). The protein content ranged between 9.88% – 10.21%. The performances of soxhlet and cold press extraction methods were compared in determining the lipid content of macroalgae. The cold pressing extraction method was shown to have a higher yield of lipid extracts than the soxhlet extraction method. The most abundant fatty acid in the macroalgae species was palmitic acid (C16:0, 35.35 – 47.34%) from saturated fatty acids (SFAs). Oleic acid (C18:1, 18.78 – 25.25%) and palmitoleic acid (C16:1, 14.24 – 15.36%) were other plentiful fatty acids from monounsaturated fatty acids (MUFAs) in the studied species. Linoleic acid (C18:2ω6), α-linolenic acid (C18:3ω3), and docosahexaenoic acid (C22:6ω3) from polyunsaturated fatty acids (PUFAs) levels varied from 3.67 – 4.64%, 4.32 – 5.68%, 1.21 – 2.75%, respectively. It was concluded that the proximate composition and types and contents of fatty acids vary depending on species, season and geography.","PeriodicalId":176110,"journal":{"name":"International Journal of Environment and Geoinformatics","volume":"15 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139270967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Descriptive statistics, independent sample T test, one-way analysis of variance ANOVA and Post hoc tests, Pearson Correlation test and regression analysis were used in the analysis of the data. In this study, internal reliability coefficients were determined as .89 for EBS and .83 for EISIFA. It can be said that the participating university students exhibited a high level of EISIFA (4.01 ± 0.54) and a moderate level of EBS (3.45 ± 0.62).

There is an ever-increasing demand for high-resolution bathymetric data for those fields since only a small portion of the world seas and oceans have been explored, observed, and charted so far. There are some sources which provide publicly available global bathymetric data to its stakeholders and users such as widely used European Marine Observation and Data Network (EMODnet) and General Bathymetric Chart of the Oceans (GEBCO). In general, it is challenging for researchers to select the best fit for their studies among available datasets, due to the fact that their sole reliability is not well-assessed. The purpose of our study, thus, is to compare those publicly available bathymetric data with field measurements obtained from the surveys carried out by the Office of Navigation, Hydrography and Oceanography for an area of interest in the southeastern Black Sea comprising various characteristics as to the bottom topography (i.e. homogeneous elevation, steep slope, mild slope, etc.). Validation is conducted focusing on these distinct features by means of visual assessment and quantitative comparison. Results reveal that, even though there is an overall agreement, local discrepancies are also present. Nonetheless, GEBCO and EMODnet datasets are proved to be great assets for any hydrospatial application that does not necessarily require high spatial resolution.","PeriodicalId":176110,"journal":{"name":"International Journal of Environment and Geoinformatics","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124948072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building disaster-resilient communities has become the goal of many disaster risk reduction (DRR) frameworks. This study aimed at quantifying the resilience of the population of Mauritius towards natural disasters using statistics drawn from secondary sources of data. A Composite Disaster Resilience Index (CDRI), which ranged from 0 to 100, was established. Four indicators and sixteen sub-indicators which reflected domains of resilience in terms of community capacity, economic, built-up environment and social, were used to develop the CDRI. Geographic Information System (GIS) was used to map the CDRI across 144 administrative areas, which included 124 Village Council Areas (VCAs) and 20 Municipal Council Wards (MCWs), for a visual representation. Resilience indices were classified into least and most resilient. Results showed a spatial variation in resilience levels towards natural disasters across the administrative areas. Nearly fifty percent of the eleven most resilient communities were found in urban areas (MCWs). Twelve administrative areas were the least resilient towards natural disasters and emerged from rural (VCAs) and marginalised areas only. Coastal villages of Grand Sable, Quatre-Soeurs, Bambous-Virieux, Le Morne and Case Noyale formed a cluster of least resilient communities along the East coast. A t-test analysis revealed a statistically significant difference in resilience levels between urban and rural regions at p < 0.05. Results suggested that infrastructure and the social capacity building were likely to be less developed in rural areas than in urban areas. Findings also demonstrated that most VCAs and MCWs performed less well in community resilience when compared to the rest of the dimensions of resilience. Results provided evidence with potential to help decision-makers in the allocation of resources to improve resilience in Mauritius.","PeriodicalId":176110,"journal":{"name":"International Journal of Environment and Geoinformatics","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115690733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ship Inspection Report (SIRE) programme Vessel Inspection Questionnaires (VIQ) inspections form one of the additional inspections complementing the regular Flag State and Port State Inspections. By consulting tanker crew and inspectors as field experts, this study utilizes a quantitative method to propose an approach for minimizing the most observed remarks of SIRE VIQ inspections.

As a result, several classification techniques exist, which are roughly classified as pixel-based and object-based classification methods. Based on the foregoing, this study provided an integrated method of deriving land use from a coarse satellite image. Location coordinates of the land uses were acquired with a handheld Global Positioning System (GPS) instrument as primary data. The study classified the image quantitatively (pixel-based) into built-up, water, riparian, cultivated, and uncultivated land cover classes with no mixed pixels, and then qualitatively into educational, commercial, health, residential, and security land use classes that were conflicting due to spectral similarity. The total accuracy and kappa coefficient of the pixel-based land cover classification were 92.5% and 94% respectively. The results showed that residential land use occupied an area of 5500.01ha, followed by educational (2800.69ha); security (411.27ha); health (133.88ha); and commercial (109.01ha) respectively. The integrated method produces a crisp-appearance like the object-based image classification method. It eliminates the \"salt and pepper\" appearance that a traditional pixel-based classification would have. The output can be a vector or raster model depending on the purpose for which it is created.","PeriodicalId":176110,"journal":{"name":"International Journal of Environment and Geoinformatics","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133934827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
