The raw data of manuscript 'Abundance, composition, and environmental implications of iron minerals in high-permeable sandy beaches'

The raw data of manuscript 'Abundance, composition, and environmental implications of iron minerals in high-permeable sandy beaches'. The data include the data of 5 times 2D profile sampling of pore water presented in the article (salinity, redox potential, dissolved oxygen, total alkalinity, ammonium ion, phosphate ion, total dissolved phosphorus), sequential extraction and microwave digestion data (Fe Carb, Fe Ox1, Fe Ox2, Fe Mag, Fe Total, SOC, Al, Mn, P (Ox1), P (Ox2)), water level data (P1, P2, P3), and data comparison (comparison between spectrophotometry and ICP-OES).
