Occurrence pattern of SGLs shows that maximum number of lakes (> 80%) are persistent in nature, followed by drain-out (15–20%) and recurring type lakes (7–8%). Because of this, and because such lakes have caused major GLOF (glacial lake outburst flood) events before, international organisations have been developing lake, The Himalaya, the world's highest mountain ranges, are home to a large group of glaciers and glacial lakes. The analysis of 248 groundwater samples collected across one monsoonal season indicates that the anisotropic coastal aquifer is affected by salinity. 2. The results show that, in the past 30 years, (1) the survived glacial lake expansion was a dominant contributor to the increase of glacial lake area, accounting for about 67%, and new formed lakes contributed to the rest 33% of area increment; (2) glacial lake area was averagely increasing in all 100-m-elevation bands where the largest growth occurred at elevations of 5000-5300 m, indicating a vertical variety of climate changes; (3) the more closer the glacial lake is to its parent glacier, the greater the area increasing rate of the glacial lakes, and among 15 types of glacial lake-glacier distance variation, 60% of net lake area increment was due to the lakes directly connected with parent glaciers in the 2000s in Chinese Himalaya. The changing patterns of supraglacial lakes and proglacial lakes are rather complex, involving both lake disappearance and emergence. The annual mapping of SGLs was also performed for four consecutive years (2014–2017) to analyze their nature and occurrence pattern. The Lo Valdés Formation as redefined here overlies the Catedral Formation; it is 539 m thick in the type locality, 582 m thick at Cajón del Morado and 150 m thick at Cruz de Piedra. of water blooms in some ponds of NE India’.

At the same time, the results from a cryosphere programme of the Indian Space Research Organization (ISRO) started to arrive, where satellite data of Indian Remote Sensing Satellite (IRS) 1C and 1D were analysed. Phytoplankton is distinctly speciose in contrast to the reports from the sub-tropical reservoirs of Meghalaya (Sharma, 1995;Sharma and Lyngdoh, 2003), the floodplain lakes of Assam (Laskar and Gupta, 2009;Gupta and Devi, 2014;Devi et al. We conducted an integrated field mapping, geochronological study, and geochemical analysis of the Lesser Himalayan Sequence strata in the Kumaun and Garwhal Himalaya of NW India (78°00′-80°30′E). Phytoplankton indi-cates moderate species di-versity and depicts domi-nance and evenness varia-tions. During the Berriasian, the dominance of Cosmopolitans and abundance of Indo-Pacific taxa suggests that new pathways opened between Antarctica and South America–Africa. The succession of Olcostephaninae from the Chañarcillo Basin of northern Chile is described in the light of new collections and revision of historical material. The repetitive calculated values of all the morphometric parameters of different litho - tectonic zones were processed in the form of diagrams. A major conclusion is that trace geochemically reactive minerals in the bedrock contribute the bulk of the solute found in runoff. In addition, bioclast is more than microfacies element other in both stratigraphic columns. Himalaya, India, using multi-years satellite dataset of Landsat 3.5 /5 View 12+ photos. The largest lake in the Himachal Pradesh has been classified as other moraine-dammed lake (1.0±0.03km2) is sited at frontal of Samundra Tapu Glacier in the Chandra basin. Uttarakhand Himalaya. This will benefit in early warning and disaster risk reduction of downstream communities. This work applies binary maximum-length sequences (MLS) as periodic perturbation signals for sonar systems. The maximum number of glacier lakes are seen in the Miyar basin (156 counts), whereas minimum lakes are located in the Siul basin (06). The entire Himalayan region is prone to disasters, with many people being vulnerable to hydroclimatic threats such as extreme rainfall-driven floods, glacial lake outburst floods (GLOFs), landslide lake outburst floods (LLOFs), and landslides triggered by rainfall. cladocerans in December-January and copepods in May-June.

Limnological data of four high altitude lakes from the cold desert region of Himachal Pradesh, India, has been correlated with cyanobacterial diversity. which modifies the, Climatic change-induced glacier recession has been accompanied by formation and growth of proglacial lakes in the Himalayan region, which pose an emerging significant threat to the downstream communities/settlements in the form of outburst floods. In this study, twelve different microfacies types have been recognized, which can be grouped into five (micro) facies associations: peritidal, lagoon, shoal, semi restricted marine and open marine. Enhanced retreat rate of the glaciers have been observed in the Himalaya during recent years (Kumar et al. Currently, he is engaged in studies relating to productivity, population dynamics, seasonal distribution and species diversity of aquatic organisms in relation to hydrobiological factors of lentic and lotic waters of North India; assessment and impact of pollution; and bioindicators of pollution.

Out of a surprisingly large total of 156 lakes, the researchers found 16 lakes that are potentially dangerous in Himachal Pradesh. and OLI images, respectively. They are varied in different parts of the studied sections and the total amount of bioclasts in the section is more than other elements. The Pindari glacier has witnessed highest rate of retreat (73.27m) during 2009-2010. The Lo Valdés Formation is here divided into two formations, based on the lithological composition. This study is an important contribution to phytoplankton diversity of the reservoirs of India and the subtropical reservoirs in particular. The present observations may be interpreted as direct consequence of the rapidly changing climate wherein the glaciers are witnessing a negative mass balance and hence the retreat. The information helped to resolve IPCC controversy and provided invaluable insight into Himalayan cryosphere. The results of this study underline that regional climate is accelerating the cryosphere thawing and if the current trend continues, further glacier melting will likely occur. americanensis, Virgatosphinctes scythicus and Micracanthoceras microcanthum are registered for the first time in Chile. Eight third-order depositional sequences are identified on the basis of deepening and shallowing patterns in the microfacies. Here we suggest that the Baños del Flaco Formation reaches from the lower part of the Middle Tithonian to the lowermost part of the Lower Berriasian. This study provides primary data for future GLOF risk assessments. All the evaluating parameters except pH and residual sodium carbonate indicate a general unsafe characteristic of the subsurface water for domestic and agricultural utility. Because of its biological richness, the National Committee on Wetlands has designated Renuka Lake as a wetland of national importance. The discovery of a wing part with a large anal fan supports the presence of a gigantic palaeodictyopteran that can be assigned to Homoiopteridae. The trends of glacier lake evolution during the past few decades and their future development are still not well understood. Pro-glacial/moraine-dammed lakes are growing consequent to Uttarakhand Himalaya. Ammonoids have been obtained only from sandstone beds in the lower one-third and close to the top of the c. 350-m-thick section. According to the ecological index, major bioevents are recognized for the Upper Tithonian, with peak relative abundances and diversity, and for the Lower Berriasian, which is characterized by highest species richness. This late ablation period is characterized by low atmospheric input and lean flow in the glacier streams due to less availability of solar energy for supraglacial melting. (1994) ‘Ecology. Its index microfacies are carefully determined through studying of 152 thinsections. IMP CURRENT AFFAIRS PART 1-2 PDF DWONLOAD RRB NTPC. The mechanical eVects also extend farther afield due to the en- hancement of the northern westerly jet stream in the lee of the plateau. The rapid melting of glaciers had result of reduction of glacier mass with the increase in size of moraine dammed glacial lakes. The plankton revealed abundance during summer and post monsoon while the minimum number were recorded during winter. Upsection, sequence 2 represents a second cycle with transgressive facies during the Upper Tithonian and a regression in the Lower Berriasian. Analyses of the data show a progressive increase in number of glacial lakes and their areal extent. The lake is 87-m deep with a water volume of approximately 34.9-35.6 × 106 m3. The quantitative dominance of phytoplankton of the sampled reservoir concurs with the results from Meghalaya (Sharma, 1995;Sharma and Lyngdoh, 2003) and Mizoram (Sharma and Pachuau, 2016), Himachal Pradesh (Jindal and Prajapat, 2005; ...

Second, U-Pb detrital zircon dating suggests that metasedimentary strata in the Ramgarh Thrust hanging wall are correlative with basal units of the Outer Lesser Himalayan Sequence, removing the necessity that the Ramgarh Thrust hanging wall was allochthonous with respect to its footwall Lesser Himalayan Sequence units. In view of the record of the ammonoid genera Odontodiscoceras and Berriasella from the basal sandstone bed and Colombiceras, Deshayesites, Cleoniceras and Australiceras from the upper most sandstone beds, the age of the Giumal Formation is precised to range from Berriasian to Early Aptian. Intense sampling from the Giumal Formation exposed near the village of Chikkim (Spiti Valley, Himachal Pradesh, India) led to the recognition of a new Early Cretaceous ammonoid fauna. The corresponding quartz microstructures indicate that deformation occurred above 350 °C. Using MLS of pseudo-random nature, much higher signal-to-noise ratio (SNR), while keeping a similar spatial resolution as that using pulsed perturbation can be obtained.

The hydrogeochemistry is controlled by aquifer lithology with a general occurrence of ion exchange and acid–base reaction processes across the study area. lakes correspond well with the glacier recession. A lower and an upper member are distinguished by their lithological composition. Khajjiar Lake – Stunning Views. Our results highlight distinct temporal variations of di-versity parameters in comparison with the preliminary survey of June 1995–May 1996. Seven potentially dangerous lakes are identified and analysed qualitatively for outburst probability. However, in the period from July to September, the stream water carries the chemical signature of monsoonal precipitation. Therefore, based upon minimal observations, numerous conclusions were made about glacier mass, length, and area loss, leading to the erroneous conclusion by the Intergovernmental Panel on Climate Change (IPCC) in 2007.
