Modelling and processing of flexural wave noise in sea ice
Jensen, Kristian (Master thesis, 2016-04-12)One of the most common problems with seismic data obtained on sea ice is the presence of flexural ice wave noise on the seismic raw data. Flexural wave noise occurs on seismic data acquired on ice in the so-called transition ... -
Point-spread function convolution to simulate prestack depth migrated images: A validation study
Jensen, Kristian; Lecomte, Isabelle Christine; Gelius, Leiv-J.; Kaschwich, Tina (Journal article; Peer reviewed, 2021)Seismic migration commonly yields an incomplete reconstruction of the Earth model due to restricted survey aperture, band-limited frequency content and propagation effects. This affects both illumination and resolution of ... -
Seismic modelling and deconvolution of prestack depth migrated images through ray-based Point-Spread Functions
Jensen, Kristian (Doctoral thesis, 2021-12-15)Seismic modelling involves simulating the propagation of waves through an Earth model to retrieve information about the subsurface. If an a priori Earth model is known, seismic modelling allows geoscientists to assess how ... -
Seismic on floating ice: data acquisition versus flexural wave noise
Johansen, Tor Arne; Ruud, Bent Ole; Tømmerbakke, Ronny; Jensen, Kristian (Journal article; Peer reviewed, 2019)Geophysical surveying of the Arctic will become increasingly important in future prospecting and monitoring of the terrestrial and adjacent areas in this hemisphere. Seismic data acquired on floating ice are hampered with ...
