Charlotte (North Carolina), ISSN 0749-0208. Jet-grouting has been widely used as a ground improvement method in several fields of geoengineering, but most of the case studies have focused on embankments and excavations. This paper describes the performance of a gravity block-type quay wall in the southwest coast of Korea where the underlying soft clayey soils were improved by jet-grout columns. The scheme and properties of jet-grouting and the construction history and measured behavior of the wall-soil system are presented. A finite element analysis was conducted to estimate the settlement, lateral displacement, and horizontal earth pressure of the quay wall. The computed results compare well with the field data during and after construction. The effect of area replacement ratio, quantifying the degree of ground improvement, on the response of the quay walls was also investigated. The field and numerical results show that the jet-grout columns enhanced the performance of the block-type quay wall over soft soils.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141688988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Charlotte (North Carolina), ISSN 0749-0208. The current study was carried out between September 2022 to September 2023 from SE coast of Tamil Nadu for Parapenaeopsis shrimp. This shrimp, estimated to rank third in shrimp production, landed as 2216, 2032, and 1704 kg from Thoothukudi, Mandapam, and Nagapattinam landing centers, respectively. The catch per unit effort was calculated to check the abundance of this species and ranged from 21.83 to 96.41 kg, averaging 46.33% in both years. The total length of males and females was observed in the range of 5.5 to 10.5 cm and 6.5 to 12.5 cm, respectively. Female shrimp attained first maturity at 6.5 cm, whereas male shrimp were 5.5 cm. The gonadosomatic index was calculated and found to be the highest (5.64–5.78) in March and September and the lowest in April and October for both years. The absolute fecundity for P. maxillipedo was recorded and ranged from 38,500 to 1,32,000 ova per female. The highest index of relative importance was observed in October and April for both male (57.04) and female (73.82) shrimp. To estimate von Bertalanffy's growth equation in P. maxillipedo, the asymptotic length and growth coefficient (K) growth parameters were combined for both sexes and analyzedas 13.55 cm and 1.5 y–1, respectively. The total mortality and natural mortality (M) were observed as 3.04 and 2.86 y–1, respectively. Hence, fishing mortality was 0.18 y–1, and the exploitation rate (E) was 0.06. The length at first catch per length (LC/L) and M/K values were calculated using the Y/R model as 0.52 and 1.2 for males and 0.48 and 1.3 for females, respectively. E was observed as 0.06, which was lower than the maximum E of 0.4, which showed that the P. maxillipedo fisheries along the SE coast of Tamil Nadu were at unexploited conditions.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141699480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Charlotte (North Carolina), ISSN 0749-0208. Coastal sand dunes are dynamic and fragile ecosystems found along some sandy shorelines. They are typically supported by a wide variety of specialized floral and faunal life. Coastal sand dunes are especially common in temperate coastal areas but are less abundant in tropical or subtropical coasts. A comprehensive study of flora in the Manalkaadu sand dune ecosystem was completed from August 2022 to May 2023, using 50-m × 5-m belt transects. The study area was divided into nine distinct locations for systematic sampling. Ipomoea imperati (Vahl) Griseb., a dicotyledonous flowering plant commonly known as fiddle-leaf morning-glory of the Convolvulaceae family, was recorded for the first time in the Manalkaadu sand dunes of the Northern Province in Sri Lanka during the study. Ipomoea imperati has smooth trailing stems that are covered with alternately arranged lanceolate, fleshy dark green leaves with a notched apex. Ipomoea imperati bloomed from September 2022 to March 2023 in the study area, and the funnel-shaped flowers were fused with white petals and yellow centers. In the area where it was discovered, the species withstood high substrate temperatures (about 29°C to 35°C), sand scouring, and moderate burial by accreted sand. Out of nine sampling locations, I. imperati was found in five locations. The plant density (two to six), plant percentage frequency (40% to 60%), Shannon Wiener diversity index (0.54 to 1.43), species evenness (0.50 to 0.90), and richness (2 to 5) were also analyzed. Thus, the density of I. imperati in five sampling locations was considered to be moderate, whereas the diversity was very low. It is designated as endangered in the National Red List 2020—Conservation Status of the Flora of Sri Lanka.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141698466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building community resilience and adaptation to climate change: Integrating disaster risk reduction in the coastal regions of Bangladesh. Journal of Coastal Research, 40(4), 792–802. Charlotte (North Carolina), ISSN 0749-0208. Building community resilience is very significant in reducing climate shocks and disaster risk. There is some insufficiency in community resiliency among coastal communities of Bangladesh, so they are still suffering from disastrous events like cyclones, floods, riverbank erosion, heavy rain, salinity, and tidal surges. So, this study critically examined the impacts of disasters on coastal communities and how they can build their resilience to reduce disaster risk. This study emphasizes the local adaptation strategies for risk reduction and the barriers faced by the local coastal community that hinder disaster resilience. The study was conducted from November 2022 to March 2023. A mixed-method research approach was utilized to assess the situation. In order to gauge the resilience of the community, the study focused on social, economic, infrastructure, and institutional dimensions based on different established climate disaster resilience indexes and frameworks. Key informant interview and face-to-face interview methods were used for data collection. Findings showed that the main barrier to sustainable adaptation and community resilience is the poor socioeconomic conditions of the community in the study area. Lower rates of quality education, limited livelihood opportunities, lack of other resources, and repeated disastrous events cause poor socioeconomic situations for those communities. The results show that the area is highly dependent on agriculture and fishing, so there needs to be special consideration given to disaster tolerance cultivation. In addition, the collaboration of locally grounded adaptation solutions and technological solutions should be emphasized for sustainable adaptation and will be necessary to ensure sustainable livelihoods. The study suggests that policymakers prioritize social and institutional support in building community resilience to reduce disaster risk.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141689361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Observer systems for monitoring and collecting catch information from pelagic fisheries are essential in ensuring the sustainable harvesting of pelagic fisheries resources. The emergence in recent years of electronic observers that rely on video surveillance is gradually becoming a complementary or alternative measure to human observers. Electronic observers' security and ease of use make full electronic monitoring (EM) of ocean-going fishing ships possible while ensuring complete data availability. The development and improvement of its standards are the keys to ensuring the large-scale application of EM. This paper summarizes and justifies the minimum standards for EM for pelagic fishing by analyzing the standards and current status of human observers, documenting the functions and applications of EM systems, comparing the monitoring capabilities of human observers and EM, and analyzing the characteristics of the three main fishing methods: purse seine, trawl, and longline, respectively, in terms of equipment platform technology, data collection, and data management. The development of EM standards can clarify the cost of the entire monitoring process, ensure the compliance and economics of EM, and achieve effective long-term monitoring of pelagic fishing.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141699996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, cellular changes and biological indices in the liver tissue of the common sole, Solea solea (L. 1758), are investigated based on sex, size groups, and seasons. The specimens used in the study were obtained monthly between 2019 and 2020 from commercial trawlers and small scale–fishing operations in the fishing grounds of Izmir Bay, the Aegean Sea coast of Turkey. A total of 240 common sole fish (166 female, 66 male, 8 immature) were used in this study. In the obtained specimens, the male: female ratio was determined as 0.39:1 (χ2 = 33.19; p > 0.05), whereas the length–weight relationship was calculated as W = 0.009TL2.97 (R2 = 0.86) for females and W = 0.009TL3.27 (R2 = 0.91) for males. Four size groups (19–22, 23–26, 27–30, >30cm) were established in the study. Significant histological changes, such as macrovesicular steatosis degenerations, were observed in the liver tissue of the examined fish, especially in larger size groups. Females exhibited higher levels of condition and hepatosomatic index values compared with males, possibly because they are more susceptible to liver degeneration. During the summer months, liver degeneration is more striking due to hunger among common soles. Based on these results, 36.7% of the specimens caught from fishing grounds in Izmir Bay have normal liver tissues, whereas 11.3% have macrosteosis and 8.3% have a sinusoidal hemorrhage.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141712547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Iva frutescens L., also known as marsh elder, has a broad distributional range, from the Atlantic coast of Nova Scotia, Canada, to Florida in the United States and from Florida on the Gulf of Mexico to the central Texas coast. Iva frutescens typically occurs in the upper tidal ecotone of salt marshes with more terrestrial upland vegetation. Marsh elder is a hardy shrub that is relatively intolerant to flooding but has a relative tolerance to low soil salinity. Iva frutescens recovers quickly after cutting and fire and may be important in blocking the invasion of Phragmites australis into reconstructed salt marshes. Borrichia frutescens and I. frutescens are associated with the phenomenon of associational resistance.

Charlotte (North Carolina), ISSN 0749-0208. Mangroves are essential to the stability of coastal regions, especially when facing the threat of climate change. However, deforestation, land use changes, and rising sea levels destroy mangrove forests. Based on bibliometric analysis, this paper aims to gain insight into the impact of climate and land use changes on mangroves. By searching Scopus, 534 pieces of literature from 2013 to 2023 were found, and they were analyzed based on bibliometric information and article metadata. Trends and hotspots of the impact of climate and land use changes on mangrove research were explored using VOSviewer software. The results of a network co-occurrence analysis revealed that mangroves, climate change, land use change, blue carbon, and wetlands represent the most popular central areas of study. The results of this paper show that the countries with the greatest number of publications on mangroves and climate and land use changes are the United States, Australia, India, Indonesia, and China. The research findings revealed that remote sensing and geographic information systems (GIS) are the most recently used technologies to enhance the research field of ecosystem monitoring in mangrove research. Maintaining and increasing carbon sinks through sustainable management of mangrove ecosystems have been a potential priority in climate change and mangrove ecosystem research development. This research highlights trends in the impact of climate and land use changes on mangrove ecosystem research over the past 10 years. It identifies areas that require further research investment to promote future research collaboration.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141694448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
