SNP is situated in the Solu Khumbu district, in the north eastern region of Nepal and represents the Northernmost part of the Dudh Koshi River Basin, which is part of the Koshi River Basin or SaptaKoshi Basin , one of the seven major hydrographic basins into which Nepal is subdivided. The SNP covers an area of 1141 km2 and is surrounded on all sides by the highest mountain ranges on Earth. The terrain is extremely irregular, with altitudes that reach 8848 m. The lower topographic limit of permanent snow cover is located at an altitude of 5500 5600 m. The climate of the SNP is driven by the Asian monsoon. The lake bedrock is mainly Late Tertiary Granites, with a primarily quartz silicate composition and a low weathering rate. Soils are absent or very thin in most of the catchments. Vegetation cover is restricted to small areas of alpine meadow. The lake surface area is 0.009 km2. The lake lies above 5000 m a.s.l., the tree line limit. The lake is ice covered for ca. 9 10 months every year from October November to June July . Chlorophyll a concentrations are below 1µg l 1 and are probably controlled by strong grazing pressure from a large pigmented keto carotenoid of astaxanthin type zooplankton community. Total phosphorus concentrations mean values are about 2 µg P l 1, whereas total nitrate concentrations are about 120 µg N l 1. Concentrations of particulate organic carbon POC and dissolved organic carbon DOC are very low. Paleolimnological studies covering the last ca. 3500 yrs B.P confirmed the high sensitivity to climatic forcing of this environment with oscillation that mimic warm and cold period and the recent warming. Paleolimnological results are in agreement with the evidence of long term monitor data on lake chemistry strong variability in lake chemistry, which in turn drives the variability in lake production and the composition of algal assemblages La rete italiana per la ricerca ecologica di lungo termine Lo studio della biodiversita e dei cambiamenti Capotondi, Lucilla; Ravaioli, Mariangela; Acosta, Alicia; Chiarini, Francesca; Lami, Andrea; Stanisci, Angela; Tarozzi, Leone; Mazzocchi, Maria Grazia Published version https //doi.org/10.5281/zenodo.5584749 Capitolo Contributo in volume simona.musazzi MUSAZZI SIMONA gianni.tartari TARTARI GIANNI marinamarcella.manca MANCA MARINA MARCELLA claudia.giardino GIARDINO CLAUDIA angela.boggero BOGGERO ANGELA liciamaria.guzzella GUZZELLA LICIA MARIA michela.rogora ROGORA MICHELA franco.salerno SALERNO FRANCO paolo.cristofanelli CRISTOFANELLI PAOLO alessandro.oggioni OGGIONI ALESSANDRO angela.marinoni MARINONI ANGELA andrea.lami LAMI ANDREA mariano.bresciani BRESCIANI MARIANO gabriele.tartari TARTARI GABRIELE erica.matta MATTA ERICA paolo.bonasoni BONASONI PAOLO eLTER European Long Term Ecosystem and socio ecological Research Infrastructure Advance_eLTER Advancing the European Long Term Ecosystem, critical zone and socio ecological Research Infrastructure towards ESFRI eLTER PLUS European long term ecosystem, critical zone and socio ecological systems research infrastructure PLUS eLTER PPP eLTER Preparatory Phase Project DTA.AD001.003.002 European Long Term Ecosystem and socio ecological Research Infrastructure eLTER IREA DTA.AD001.347.006 eLTER PLUS IREA DBA.AD002.319.001 ELTER PPP |
