	C cycle in Lake Kivu
		Lake Kivu is a meromictic lake with a relatively shallow euphotic layer (~18m) usually smaller than its oxic mixolimnion (20-60 m), and with a weak thermal gradient in the mixolimnion.
		Lake Kivu has unique limnological characteristics, with temperature and salinity increasing in the deep water layers, due to the input of geothermal sources at the bottom of the lake.
		As in all Eastern Africa, the Lake Kivu region is characterized by a windy dry season (from June to September) and a calmer rainy season (October-May).

	Lake Kivu - Definition, explanation
		Lake Kivu is one of three known exploding lakes, along with Cameroonian Lake Nyos and Lake Moroun, that experiences lake overturns.
		Lake Kivu's methane was only originally thought to be a cheap natural resource for export and the generation of cheap power.
		Once the mechanisms that caused lake overturns began to be understood the risk the lake posed to the local population began to be understood.

		Lake Kivu is one of three known exploding lakes, along with Cameroonian Lake Nyos and Lake Monoun, that experience violent lake overturns.
		The gaseous chemical composition of exploding lakes is unique to each lake; in Lake Kivu's case, methane and carbon dioxide due to lake water interaction with a volcano.
		Lake Kivu has recently been found to contain approximately 55 billion cubic metres of dissolved methane gas at a depth of 300 metres.

	AVEC: Case Studies - Recovery of Gas from Lake Kivu
		There is a lake in Rwanda, Lake Kivu, where scientists have established that at depths of around 300m the water is partially saturated with methane and carbon dioxide.
		After planning to return to the lake for demonstrations in February, these finally were scheduled in mid-May. In the intervening time somebody managed to cut an anchor rope despite 24-hour guards, causing the other anchor to seriously tangle the underwater piping and cabling and then break.
		One of the big surprises observed on the lake was the effect of lake water on different metallurgies and eco-systems in the lake.

	CVO Website - Volcanic Lakes and Gas Releases
		Only three lakes in the world are known to contain high concentrations of dissolved gas in their bottom waters: Lakes Nyos and Monoun in Cameroon and Lake Kivu in East Africa.
		Lake Monoun is near the center of a volcanic field that includes at least 34 recent craters, and there is evidence that eruptive activity has occurred there as recently as a few hundred years ago.
		However, the chemistry of the lake water and sediments, the uniformly low lake temperature (23-24=B0C), and the absence of new tephra in or around the lake suggested to the research team that the August 1984 event was not the result of an eruption or a sudden ejection of volcanic gas from the lake.

		In this city of Bukavu, for example, on the shores of Lake Kivu, the population has doubled as a result of the conflict, with refugees seeking the relative security of an urban centre where some UN peacekeepers are based.

		There was a total coverage of all strata; the entire shoreline of Lake Kivu as well as that of its numerous islands were surveyed and thus a 100% of all FEU's, active on Lake Kivu between 29.06 and 30.08.1991, were accounted for.

	Lake Kivu Home
		Lake Kivu has remained stably stratified for thousands of years; however, in the last few decades much attention in the scientific field has been directed towards the lake.
		A heat flux into the lake, or other meteorological and limnological forces may cause an overturn, or later described “rollover”, of the lake releasing the dissolved CO from pressure and causing a discharge of gas that could devastate communities located on or near the lake (Rice, 2000; Kling, 1989).
		This study attempts to show the contrary; that a possible release of fatal gas is a hazard associated with the lake and the increasing levels of volcanism and rifting in the area.

	Methane gas. Kivu lake
		A small volume of lava entered Lake Kivu but had no significant consequences on the physico-chemistry of its deep gas-charged waters.
		As detected by sudden major rise in the lake level, this eruption was also remarkably associated with perhaps up to 0,6-1 m of ground subsidence in the Goma area along the axis of the rift and thus aligned with the newly formed fractures.
		Geological evidence that volcanic centers have occurred on the SW and S volcanic rift zones at or below the level of the lake render such considerations fundamental as the volcano and rift integrated multidisciplinary monitoring system is further developed.

		Lake Kivu has never had a lake overturn but along with Monoun and Nyos it is one of the three lakes in the world which contain such large amounts of carbon dioxide making it very possible that the lake could overturn at some point.
		This showed that approximately every thousand years an event occurred which caused all living creatures in the lake to be wiped out and huge amounts of vegetation to be swept into the lake, which is consistent with a lake overturn.
		If the lake was to overturn huge amounts of carbon dioxide would be released, suffocating millions of living creatures, but the lake also contains a large amount of methane which could cause explosions above the lake.
