The sampling campaign in “Krka” National Park, Croatia / 10.09.2019

Samples of water, tufa and bedrock were collected in the Krka – Zrmanja river system in collaboration with colleagues from Ruđer Bošković Institute (Zagreb, Croatia)

In the first week of September 2019, we performed the second sampling campaign of the project in one of the most prominent tufa systems in Mediterranean, the Krka river valley and the Zrmanja river, which is hydraulically connected to the Krka river. The Krka river is characterised by a series of lotic and lentic flow sections separated by picturesque tufa barriers, which have been subject to several geochemical studies in the last few decades.  The Krka – Zrmanja river system shares some typical hydrological and morphological features with the smaller Krka river system in Slovenia, but is characterised by different and variable climate at the transit from continental to sub-Mediterranean and Mediterranean climate, therefore it present an excellent natural laboratory for geochemical and isotopic studies of recent and ancient fluvial carbonate systems. The comparison of  geochemical and isotopical characteristics of carbonate formations from Slovenian and Croatian Krka river systems, we will be able to get better insight into the impact of variable climate parameters on the influence of climate on accumulation of tufa and carbon storage in terrestrial carbonates.
