Geospatial data on the sediments of Lake Balaton

Area of Science:

• Environmental Science
• Limnology
• Geochemistry

Background:

• Freshwater lakes globally face water quality degradation, with eutrophication partially reversed by conservation efforts.
• Understanding lake sensitivity to anthropogenic impacts and climate change-induced internal process alterations remains incomplete.
• Lake Balaton, a key freshwater ecosystem, exemplifies these widespread water quality challenges.

Purpose of the Study:

• To create a comprehensive sediment dataset for Lake Balaton.
• To facilitate in-depth analysis of lake internal processes and environmental changes.
• To provide a foundational resource for research on human-influenced freshwater lakes.

Main Methods:

• Collection and analysis of 4211 lake bed sediment samples from Lake Balaton.
• Measurement of key geochemical parameters including pH, calcium carbonate, organic carbon, total nitrogen, soluble phosphorus, and potassium.
• Quantification of trace elements such as magnesium, zinc, copper, and manganese.

Main Results:

• A robust database of sediment parameters has been established for Lake Balaton.
• The dataset encompasses a wide range of physical, chemical, and elemental properties.
• This detailed sediment information is crucial for understanding lake dynamics.

Conclusions:

• The compiled sediment database is a valuable asset for future research on Lake Balaton.
• This resource will support investigations into the complex interactions within freshwater lake environments.
• The findings underscore the importance of detailed sediment analysis for managing lakes affected by human activities and climate change.
