The annual mean temperature increase is about 0.6°C/10 years. The annual temperature increase due to a linear trend is maximum in May–June. During these months of hydrological spring, the rate of increase in sea surface temperature (SST) is approximately one and a half times greater than in October–November. During most of the year, the general warming of the surface water layer is not accompanied by a significant increase in the intramonthly SST variance. Such an increase is observed only in some months of transition seasons, especially during the period of hydrological spring, when the absolute value of extreme thermal anomalies and their area increase significantly. The maximum amplitudes of interannual SST variations are confined to the northwestern part of the Black Sea. Changes in the fields of the atmospheric pressure and wind have a significant impact on the spatiotemporal structure of SST. Long-term trends in the surface pressure over the Black Sea indicate an intensification of regional cyclonic activity in the atmosphere (especially pronounced since 2009), which leads to the increased generation of negative SST anomalies of significant amplitude. Such anomalies occur mainly in the warm half of the year (especially in May and October) due to the development of upwellings of wind origin of various types. In May and October, negative SST anomalies in the range of ‒(6–5)°С are characterized by the maximum areas. Warm anomalies are also most often recorded in May and (to a lesser extent) in October. They are generated by anomalous heat fluxes on the sea surface, including those in the shallow areas of the shelf, and spread to open areas of the water basin due to horizontal advection, predominantly of wind origin. The described patterns of spatiotemporal SST variability and their causes are illustrated by a comprehensive analysis of wind and SST fields of high spatial resolution during the development of extreme thermal anomalies.</p>","PeriodicalId":54911,"journal":{"name":"Izvestiya Atmospheric and Oceanic Physics","volume":"16 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140885011","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}

The lithospheric magnetic anomalies field as a reflection of the consequences of the Indian lithospheric plate subduction under the Eurasian plate is discussed in the context of modern ideas about the geological and tectonic structure and geophysical processes of the region. The sign inversion of the magnetic anomalies over the northern part of the Indian Plate observed on <i>T</i><sub><i>a</i></sub> maps is supposed as a result of the lower crust heating due to mantle processes, the rise of the Curie isotherm and, as a consequence, the loss of the initial magnetization of the lower crust. In order to study the WHS territory and its surroundings in detail, maps of the lithospheric magnetic anomalies field are constructed at the lowest level of CHAMP orbit as possible, which leads to an increase in their resolution by nearing the field sources.

In this study, we consider a methodology for identifying and mapping the negative impact of gold mining enterprises on the natural environment based on a long-term series of free-available Landsat and Sentinel-2 satellite images. This study is carried out using the example of Tenkinsky, Susumansky, and Yagodninsky districts in Magadan oblast, where the largest gold deposits are located. Identifying features of active mining areas, as well as abandoned ones (on which vegetation began to recover), have been found in satellite images. Based on the expert interpretation of the images and NDVI analysis, it is found that about 2% of the study area has been affected by gold mining. The processes of vegetation recovery are identified only on 10% of the degraded lands. In the Tenkinsky district, the area of disturbed lands for the period 2001–2021 increased more than seven times, which is associated with a substantial increase in gold mining. Using the C2RCC processor (module of the SNAP software package), the content of suspended solids in the water of the most impacted rivers, the Berelekh, Ayan-Yuryakh, and Kolyma, has been estimated in comparison with natural values (typical for noncontaminated water). We have found that the main source of suspended matter in the rivers is the alluvial gold deposits located in the floodplain of the Berelekh River. At the same time, the seasonal variability of water contamination is determined by the hydrological situation. In particular, water turbidity decreases during low water periods and increases during high-flow periods.</p>","PeriodicalId":54911,"journal":{"name":"Izvestiya Atmospheric and Oceanic Physics","volume":"12 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139667398","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}

Vegetation indices calculated from satellite images are usually considered indicators of green phytomass; they are used for its areal estimates. The task of this study is to establish the informativity of the normalized differential vegetation index (NDVI) depending on the fractional structure of living and dead aboveground phytomass, seasonal dynamics of the biological cycle, hydrothermal conditions, and landscape position. The results of monthly measurements of aboveground phytomass fractions on 13 sites in phytocenoses of forest feather grass and feather grass formations in the Burtinskaya steppe (Orenburg Nature Reserve) from May to September 2015–2020 were used. The NDVI values were calculated for each period from Landsat satellite images at all sites. Hypotheses about geobotanical, hydrothermal, phonological, and landscape factors of NDVI informativity were tested by calculating the Spearman correlation coefficients using the dispersion and multiregression analysis. The discrepancy between the seasonal peaks of the NDVI and green phytomass is not consistent with the common concept of a direct indicator value of the NDVI. The total live biomass correlates more clearly with the index in June and July; the correlation is lower in the end of the season. The NDVI index turned out to be sensitive not so much to the reserves of green phytomass, but more to the mass and proportion of forbs and the ratio of live and dead phytomass. In late spring and early summer, the NDVI is most closely associated with forbs and, in July, with cereals. The hypothesis about the possibility of screening green mass with standing dead biomass was confirmed, which leads to a decrease in the NDVI despite the preservation or growth of green phytomass. The NDVI may underestimate the real green phytomass if there is a sharp increase in the mass of standing dead biomass, usually in the second half of summer and early autumn. The NDVI more adequately reflects the state of the aboveground phytomass of steppe communities that have not been exposed to fires for a long time when compared with burned communities and fallows.</p>","PeriodicalId":54911,"journal":{"name":"Izvestiya Atmospheric and Oceanic Physics","volume":"186 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139667267","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}

Deposits similar to glacial ones have been found in the river valleys of the northern mountainous framing of the Ubsunur Basin, in its foothill part, suggesting the presence of Pleistocene glaciers extending into its flat plains. It is also assumed on this basis that, similarly to Lake Khar-Nur, the peculiar sandy massifs located in the basin could preserve relic zones of permafrost, the thawing of which contributed to the moistening of local landscapes.
