Abstract. We examine long spectral time series of inter-plume lanes observed on the 14th and 15th March 2000
with the Coronal Diagnostic Spectrometer (CDS) on-board SoHO. The observations were obtained in lines over
a wide temperature range, from the chromosphere to the corona. The statistical significance of the oscillations
was estimated by using a randomisation method. Our observations indicate the presence of compressional waves
