Meta-data-set: Groundwater sampling Hel Peninsula/ Poland from 30.09. - 07.10.2010

1.) General description of the data set:

Major elements, trace metals, radium, tritium and nutrient data of sea water, pore water and groundwater seepage and sediments (one site influenced by groundwater, one less influenced) at Hel peninsula (Puck Bay/Poland). Additionally, seepage was sampled from benthic seepage-meters. Seepage rates of the groundwater compounds were measured with benthic chambers seepage meter mode. Pore water samples were additionally obtained with groundwater lances on groundwater impacted and less impacted sites. Two well water samples from different aquifers were taken for isotopic and geochemical analyses (δ¹⁸O-H₂O, δD—H₂O, δ¹³C-DIC). The temperature field of the surface sediments was recorded via temperature profiles measured with lances.
