Date Created: 2015-02-03

This survey images the southern Magdalena Fan. It is in the upper slope where MTCs and channel-levee complexes dominate the stratigraphy. The images are published in Ortiz-Karpf et al, 2015. The role of mass-transport complexes in controlling channel avulsion and the subsequent sediment dispersal patterns on an active margin, the Magdalena Fan, offshore Colombia.

Changes in channel architecture in response to underlying bathymetry Regional Project

Variance extraction at the base of the post-avulsion channel. Notice the downdip increase in sinuosity due to underlying bathymetric anomalies (see cross-sections). A more detailed explanation can be found in Ortiz-Karpf et al (2015). The link to the paper can be found in the docs and links tab.

Changes in the architecture of a channel-levee complex in response to an underlying MTC. Regional Project

Date Created: 2015-03-20

Variance extractions of channel top and MTC top. Lines show the location of the channel seismic cross-sections. The cross sections illustrate the changes in the architecture of the channel-levee complex in response to its location with respect to the underlying MTC. A more detailed explanation can be found in Ortiz-Karpf et al (2015). The link to the paper can be found in the docs and...

Post-avulsion evolution Regional Project

Seismic cross-section showing the deposits (units F and G) resulting from the avulsion of the channel-complex in unit E. See the related scenes for the 3D relationships of the units.

Seabed dip map from the 3D seismic volume. The seabed displays a network of slope channel-levee complex-sets, MTCs and lobes. The image is published in Ortiz-Karpf et al, 2015. The link to the paper is available in the docs and links section.

Shallow subsurface MTCs Regional Project

VSA Author: Andrea Ortiz Karpf
Scenes: 0
Interpretations: 0
Date Created: 2015-03-19

Variance extraction coloured by subsurface elevation at the composite basal shear surface of shallow subsurface MTCs. The point values correspond to subsurface elevation. The MTC is continuous across a gorge between two anticlines. A more detailed explanation can be found in Ortiz-Karpf et al (2015). The link to the paper can be found in the docs and links tab.
