Abstract

Highlights

• Application of mobile underwater in situ gamma-ray spectroscopy.
• Localization of pockmarks emanating groundwater.
• Radon progeny 214Bi proved an efficient radiotracer for localization purposes.
• Potassium 40K is suggested as additional to radon radiotracers to localize fluid emanation areas whenever sediment is in mixture with the fluid or resuspension of sediment occurs.

Abstract

Eckernförde Bay in the Baltic Sea is well-known for the pockmarks areas which are located in the centre and off the southern shore-line of the bay emanating groundwater in a non-continuous but episodic way. Mobile underwater in situ gamma-ray spectroscopy is exploited proving that both 214Bi and 40K are efficient radiotracers for localization of seepage areas whenever either sediment is in mixture with the emanating fluid or resuspension of surface sediment occurs as a side effect of the fluid emanation.
