Selected Data About Geographic Locations

Selected Data About Geographic Locations

Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

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.
