The lake is polymictic and usually fully mixed due to the wind fetch of its relatively large surface area of ~750 ha. The River Spree enters the lake from south-east and the outflow is situated in the north-west of the lake. The lake has an average retention time of about 6-8 weeks. Due to its location in a transition zone from a maritime to a more continentally characterized climate, the lake experiences large annual and inter-annual variability in local weather conditions. Data availability spans the time period from 1979-ongoing. Sampling intervals are weekly and biweekly during the winter months. We monitor phytoplankton, zooplankton,  and major nutrients and abiotic variables at at weekly temporal scales at 5 different locations across the lake. Fish, macrophytes, MZB, periphyton are sampled yearly.\r\nAdditionally, we run an automatic lake station (https:\/\/www.igb-berlin.de\/messstation-mueggelsee) continuously recording water temperature, pH, oxygen, conductivity, fluorescence in -situ in real time. Moreover, the station is equipped with a meteorological station monitoring air temperature, wind, humidity, precipitation, global radiation. M\u00fcggelsee is a GLEON (Global Lakes Observatory Network http:\/\/www.gleon.org\/ ) and an LTER -D site. \r\n\r\n\r\n","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1979,"yearClosed":null,"relatedSites":null,"siteName":"M\u00fcggelsee","shortName":"LTER_EU_DE_020","siteType":"Stationary land-based site","protectionLevel":[{"label":"Category V \u2013 Protected Landscape\/Seascape\/Area","uri":"http:\/\/dd.eionet.europa.eu\/vocabularyconcept\/cdda\/IucnCategoryValue\/V"}],"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/photos\/Hintze_IGB_4582.jpg","alt":"not defined"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":12,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":null},"precipitation":{"yearlyAverage":560,"monthlyAverage":null,"unit":"mm","referencePeriod":null},"biogeographicalRegion":"continental","biome":"freshwater_lakes","ecosystemType":[{"label":"Fresh Water Lakes","uri":null},{"label":"Lakes","uri":null},{"label":"Small lakes","uri":null}],"eunisHabitat":[{"label":"Inland surface waters (C)","uri":null},{"label":"Permanent eutrophic lakes, ponds and pools (C1.3)","uri":null},{"label":"Surface standing waters (C1)","uri":null}],"landforms":null,"geoBonBiome":["Fresh water lakes"],"geology":null,"hydrology":null,"soils":null,"vegetation":null},"geographic":{"boundaries":"POLYGON ((13.622446060181 52.430091020643, 13.630857467651 52.426950901309, 13.65008354187 52.426113498372, 13.672399520874 52.43364955213, 13.678407669067 52.435010091179, 13.674287796021 52.444741953195, 13.652830123901 52.447880804995, 13.648366928101 52.447253052528, 13.63429069519 52.44693917294, 13.627939224243 52.443590984827, 13.622961044312 52.441812156384, 13.620729446411 52.435951978223, 13.622446060181 52.430091020643))","coordinates":"POINT (13.648776 52.438074)","country":["Germany"],"elevation":{"avg":32,"min":32,"max":32,"unit":"msl"},"size":{"value":730,"unit":"ha"},"relatedLocations":null},"focusDesignScale":{"experiments":{"design":"no experimentation","scale":"micro sites"},"observations":{"design":"only observation","scale":"beyond catchment"},"observedProperties":[{"label":"chlorophyll content of water","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10088"},{"label":"conductivity","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22089"},{"label":"dissolved nutrient","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22107"},{"label":"dissolved organic carbon in water","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10307"},{"label":"ecosystem parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20939"},{"label":"ecosystem structure","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/21475"},{"label":"genetic parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20942"},{"label":"inorganic nutrient content","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22137"},{"label":"lake temperature","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10011"},{"label":"nitrogen content","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22174"},{"label":"percent organic carbon","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22183"},{"label":"photosynthetically active radiation intensity","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22186"},{"label":"reflected global radiation irradiance","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22209"},{"label":"secchi depth","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22226"},{"label":"total organic carbon","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22297"},{"label":"water acidity","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22030"},{"label":"water depth","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22310"},{"label":"water parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20945"},{"label":"water reflectance","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10391"},{"label":"water salinity","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10308"},{"label":"water temperature","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22313"},{"label":"water transparency","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10392"}]},"infrastructure":{"accessibleAllYear":true,"accessType":"boat","allPartsAccessible":true,"maintenanceInterval":3,"permanentPowerSupply":true,"operation":{"permanent":true,"notes":null,"siteVisitInterval":1},"notes":"At M\u00fcggelsee the IGB runs an automatic lake station located ca. 400m off-shore.
