Drainage sampling site selection

Baltic Soil Survey Those countries which have taken part in the Baltic Soil Survey (BSS) can use the BSS soil samples in the FOREGS mapping. If you want to do so, please use the randomly selected points provided by the GSF to select the nearest BSS sampling site. The stream sediment, stream water and optional overhank sediment samples should be taken from the same small catchment and the floodplain sediment from the adjacent large drainage basin. You can decide whether you want to use the BSS samples or take new residual soil samples. If you use a BSS sample, mark it on the field observation sheet.
