In a sense, the finer-resolution analysis pursues the same goal as the usage of progressively reduced grid sizes in succeeding from coarse-resolution to eddy-permitting and then to eddy-resolving in numerical models of ocean circulation. Thus, the high-resolution regional climatologies are now closing the gaps existing between observations and model simulations allowing meaningful data-model comparisons in critical data-rich regions, such as the Northwestern Atlantic, Northeast Pacific Ocean, and several others. In this paper, we briefly review the locations, timing, purpose, and specificity of the regional ocean climatologies developed at the National Center for Environmental Information of the National Oceanic and Atmospheric Administration. We describe the Northwestern Atlantic Regional Climatology, version 2 in more details and demonstrate how this regional climatology contributes to a better understanding of the long-term climate state and variability","PeriodicalId":489105,"journal":{"name":"Journal of marine science research and oceanography","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139625018","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}

Subsequently, various conservation measures were implemented by the government and non-governmental organizations to improve sustainable agricultural production. This study was designed to identify, measure, and describe indigenous and introduced soil and water conservation practices in four zones of Southern Ethiopia, namely Wolaita, Hadiya, Kambata Tambaro, and Dawro. It was found that biological, physical, and agronomic measures were implemented in the study area. However, the technical evaluation results reveal that certain practices, such as traditional cutoff drain, fanya juu, soil bund, stone-faced soil bund, brushwood, and gabion check-dams face technical, social, and institutional challenges. The results also indicate that less attention has been given to indigenous SWC practices by different stakeholders including government organizations (GOs), non-governmental organizations (NGOs), and research institutes. As a result, their respective dimensions were not modified, effective measures were not upscaled, and circulated to other areas with similar agroecology and farming systems. In general, farmers in the study area are well acquainted with soil erosion, its causes, and the consequent reduction in land productivity. The results of our research will undoubtedly aid in identifying and documenting the practices that have been identified for future reference.","PeriodicalId":489105,"journal":{"name":"Journal of marine science research and oceanography","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135917123","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}
