The Clean Water Act in the USA and the Water Framework Directive (WFD) in Europe are the legal frameworks to facilitate the achievement of this goal. The question is raised of whether more information can be extracted from WFD-related groundwater data. To answer it, a methodology has been developed that is easy to use and could be implemented into official practice. A case study is presented in which the groundwater data of a sodic area in Austria (Seewinkel) is assessed. Eighteen parameters in groundwater sampled from 23 wells (1991-2011) were analyzed. With basic statistics, trend-, cluster-, Wilks’ λ and spatial sampling density analysis, local phosphorus and boron phenomena were described, along with the determining role of sulphate, groundwater flow, and the oxygen gradient in the area. As a final step, the spatial sampling density was determined. Regarding the current set of parameters, all the sampling sites are necessary and only in the case of certain parameters (Ca2+, Mg2+, K+, NO3-, pH) could one sampling site be abandoned. The methodology applied brings a new perspective to exploring groundwater data collected according to the requirements of the WFD.}, keywords = {Austria; Groundwater management; multivariate data analysis; Spatial sampling density analysis; European Water Framework Directive (WFD)}, year = {2014}, eissn = {1435-0157}, pages = {779-794}, orcid-numbers = {Hatvani, István Gábor/0000-0002-9262-7315; Kovács, József/0000-0002-6797-2504} } @article{MTMT:2715015, title = {Dendrokronológiai vizsgálatok a szokolya- királyréti fa harangláb anyagán}, url = {https://m2.mtmt.hu/api/publication/2715015}, author = {Kern, Zoltán and Árvai, Mátyás and Grynaeus, András}, journal-iso = {ARCHEOMETRIAI MŰHELY}, journal = {ARCHEOMETRIAI MŰHELY}, volume = {11}, unique-id = {2715015}, issn = {1786-271X}, year = {2014}, pages = {71-76}, orcid-numbers = {Kern, Zoltán/0000-0003-4900-2587} } @article{MTMT:1989093, title = {Multiple tree-ring proxies (earlywood width, latewood width and δ13C) from pedunculate oak (Quercus robur L.), Hungary}, url = {https://m2.mtmt.hu/api/publication/1989093}, author = {Kern, Zoltán and Patkó, M and Kázmér, Miklós and Fekete, József and Kele, Sándor and Pályi, Z}, doi = {10.1016/j.quaint.2012.05.037}, journal-iso = {QUATERN INT}, journal = {QUATERNARY INTERNATIONAL}, volume = {293}, unique-id = {1989093}, issn = {1040-6182}, keywords = {RECONSTRUCTION; CELLULOSE; climate; Precipitation; TIME-SERIES; dendroclimatology; NORTHERN FINLAND; SIGNAL-STRENGTH; STABLE-ISOTOPES; CARBON-ISOTOPE RATIOS}, year = {2013}, eissn = {1873-4553}, pages = {257-267}, orcid-numbers = {Kern, Zoltán/0000-0003-4900-2587; Kázmér, Miklós/0000-0003-1092-1316; Kele, Sándor/0000-0002-8607-7636} } @article{MTMT:1895896, title = {Introducing sampling frequency estimation using variograms in water research with the example of nutrient loads in the Kis-Balaton Water Protection System (W Hungary)}, url = {https://m2.mtmt.hu/api/publication/1895896}, author = {Kovács, József and Korponai, János and Kovácsné Székely, Ilona and Hatvani, István Gábor}, doi = {10.1016/j.ecoleng.2012.02.004}, journal-iso = {ECOL ENG}, journal = {ECOLOGICAL ENGINEERING}, volume = {42}, unique-id = {1895896}, issn = {0925-8574}, abstract = {In most of the world along with urbanization came the deterioration of surface waters. The case of Hungary's Lake Balaton (the largest shallow freshwater lake in Central Europe) and its catchment area was no exception. In the second part of the twentieth century it became clear that measures had to be taken to prevent further water quality deterioration. In order to do so, the Kis-Balaton Water Protection System (KBWPS) was established. To measure its effectiveness in filtering Lake Balaton's water input, total phosphorus and total nitrogen loads are regularly estimated. In this study the practice of temporal sampling frequency estimation is described using data series from the KBWPS in order to suggest a sampling frequency that is suitable for estimating annual nutrient loads and still produces a dataset from which environmental processes can be followed. In this case, temporal sampling frequency estimation was conducted using variogram analysis, before which trend removal was performed on four sampling sites and two daily sampled parameters for the years 1993–2007. Although the calculations were only carried out on two parameters they are applicable to other environmental parameters as well. Nutrient load estimation is used as a verification tool. The result of the variogram analysis pointed towards a three-day sampling frequency for the whole KBWPS in the case of total phosphorus and total nitrogen (if the purpose of the monitoring is nutrient estimation). This reduction in sampling frequency would make an approximately 50% cost reduction possible. The study gives an example of sampling frequency estimation which is a key question in every aspect of environmental science, so that hopefully it will be useful for scientists dealing with water protection issues.}, year = {2012}, eissn = {1872-6992}, pages = {237-243}, orcid-numbers = {Kovács, József/0000-0002-6797-2504; Korponai, János/0000-0003-0211-192X; Hatvani, István Gábor/0000-0002-9262-7315} } @inbook{MTMT:1503532, title = {Balaton-felvidéki tölgyek évgyűrűszélességének kapcsolata a Balaton vízszintingadozásával}, url = {https://m2.mtmt.hu/api/publication/1503532}, author = {Kern, Zoltán}, booktitle = {Környezettörténet}, unique-id = {1503532}, year = {2009}, pages = {357-366}, orcid-numbers = {Kern, Zoltán/0000-0003-4900-2587} } @article{MTMT:1334726, title = {Dendrológia alkalmazása a geomorfológiai kutatásokban (Dendro-geomorfológia)}, url = {https://m2.mtmt.hu/api/publication/1334726}, author = {Kiss, Tímea and Sipos, György}, journal-iso = {FÖLDRAJZI KÖZLEMÉNYEK}, journal = {FÖLDRAJZI KÖZLEMÉNYEK}, volume = {133}, unique-id = {1334726}, issn = {0015-5411}, year = {2009}, pages = {13-21}, orcid-numbers = {Kiss, Tímea/0000-0002-2597-5176; Sipos, György/0000-0001-6224-2361} } @article{MTMT:1378470, title = {Long-term summer temperature reconstruction inferred from tree-ring records from the Eastern Carpathians}, url = {https://m2.mtmt.hu/api/publication/1378470}, author = {Popa, I and Kern, Zoltán}, doi = {10.1007/s00382-008-0439-x}, journal-iso = {CLIM DYNAM}, journal = {CLIMATE DYNAMICS}, volume = {32}, unique-id = {1378470}, issn = {0930-7575}, year = {2009}, eissn = {1432-0894}, pages = {1107-1117}, orcid-numbers = {Kern, Zoltán/0000-0003-4900-2587} } @article{MTMT:1502634, title = {Changes of frost damage and treeline advance for Swiss stone pine in the Calimani Mts.
