Hydro-carbonates with alkali metal cations (Na+ + K+), distinguished as soda, are found only in local areas in fault zones and those of granite intrusion contacts. They are the least mineralized (no more than 100 mg/dm3) in the seasonally thawed layer and river valley taliks, but even there, in separate foci at the elevation of above 1600 m, soda water springs with the mineralization exceeding 200 mg/dm3 occur. Soda waters in Cretaceous coal-bearing deposits within intermountain artesian basins are the most mineralized (up to 3000 mg/dm3). The association of these waters with deep fault zone has been assumingly traced. The sharp increase of the dissolved carbon dioxide and the carbonic acid anions in waters at local river valley sites is offered as the indicator of the current ingress of carbon dioxide into underground waters. Soda waters with mineralization exceeding 600 mg/dm3 , contained in some samples, are referred to balneal. Hydrogeochemical methods are proposed for further study of the role of deep faults in soda waters formation as well as for the possible use of them for curing and preventing diseases.","PeriodicalId":341033,"journal":{"name":"Bulletin of the North-East Science Center","volume":"103 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127459731","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}

Six pollen zones were defined for this interval, which spans marine isotope stages (MIS) 101 and 100. Pollen zones 1 and 2 (MIS 101) as well as zones 3 and 4 (MIS 100) indicate the presence of Larix and Larix-Betula forests during interglaciations. The plant communities reflected in the spectra of zone 3 represent the warmest climates during the early Gelasian Age. During MIS 100, the period of maximum climate cooling is marked by the regional presence of shrub and herb dominated tundra (pollen zone 5). During the interstade (MIS 100, zone 6), the vegetation was dominated by Larix forest tundra. Pollen zones 3 and 4, which have spectra more indicative of interglacial rather than glacial plant communities, are more consistent with climate of MIS 101 and not MIS 100, as suggested by the core's age model. The incorrect age assignment of the boundary between these stages indicates that the Lake El'gygytgyn age model needs revision.","PeriodicalId":341033,"journal":{"name":"Bulletin of the North-East Science Center","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116200232","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}

It was established that eggs remaining after spawning in the pollock female body cavity are not resorbed simultaneously. 2 months after mass spawning, 2.7 % of them still retain fertility, and, with artificial insemination, they are characterized by high survival, suffering no violations during embryogenesis. Data on the embryonic development of the species, the timing of the steps and main stages of embryogenesis, and the amount of heat required to achieve them are given. It is shown that pollock eggs and pre-larvae from residual fertility are significantly smaller in metric parameters than those from natural spawning, but morphologically are identical to them. Regional features of morphometric indicators for eggs and newly hatched pollock larvae in the northern part of the Sea of Okhotsk were revealed.","PeriodicalId":341033,"journal":{"name":"Bulletin of the North-East Science Center","volume":"53 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132801776","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}

It has been established that in April through late June this species is represented in the littoral by individuals in the second year of life (1+) (body length 35-67 mm, body weight 0.19-1.37 g) as well as by individuals aged 2+ to 7 years (64-143 mm, 1.09-15.9 g, respectively), which form two rather well-separated size groups of fish. In August, as the size of individuals in the second year of life (1+) increases, these groups merge, forming a single bimodal curve of size composition. In the second half of June, underyearlings of the stone cockscomb, 16-20 mm long with a body weight of 20-30 mg, begin to appear in the intertidal zone, forming the third size group from 20 to 35 mm with a body weight of 40-230 mg in July. Therefore, starting from July, in the intertidal zone of Avacha Bay, the stone cockscomb of all age groups, from underyearlings to individuals 7+ years old, lives. Data on seasonal changes in the ratio of juveniles and adult fish in the intertidal zone are presented.","PeriodicalId":341033,"journal":{"name":"Bulletin of the North-East Science Center","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132294937","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}
