Clinoform systems: Review and dynamic classification scheme for shorelines, subaqueous deltas, shelf edges and continental margins
Patruno, Strefano; Helland-Hansen, William (Peer reviewed; Journal article, 2018-10)Clinoforms are inclined and normally basinward-dipping horizons developed over a range of spatial and temporal scales in both siliciclastic and carbonatic systems. The study of clinoform successions underpins sequence ... -
The distribution of rivers to terrestrial sinks: Implications for sediment routing systems
Burr Nyberg, Bjørn; Gawthorpe, Rob; Helland-Hansen, William (Peer reviewed; Journal article, 2018-09)Empirical observations used to constrain controls on large global modern river systems typically use catchment delineations depicting drainage patterns of rivers to oceans. A key component in the spatial and temporal ... -
Editorial: Sedimentary System Response to External Forcings: A Process-Based Perspective
Romans, Brian W; Fosdick, Julie C; Poyatos More, Miquel; Helland-Hansen, William (Journal article, 2020) -
The largest delta plain in Earth's history
Klausen, Tore Grane; Nyberg, Bjørn R.; Helland-Hansen, William (Peer reviewed; Journal article, 2019-03-22)Delta plains host heavily populated and extensive agricultural areas with strong anthropogenic overprints on the natural evolution of these important landforms. Furthermore, modern delta plains have formed over a short ... -
Linking an Early Triassic delta to antecedent topography: Source-to-sink study of the southwestern Barents Sea margin
Eide, Christian Haug; Klausen, Tore Grane; Katkov, Denis; Suslova, Anna; Helland-Hansen, William (Peer reviewed; Journal article, 2018-01)Present-day catchments adjacent to sedimentary basins may preserve geomorphic elements that have been active through long intervals of time. Relicts of ancient catchments in present-day landscapes may be investigated using ... -
Progradation rates measured at modern river outlets: A first-order constraint on the pace of deltaic deposition
Aadland, Tore; Helland-Hansen, William (Peer reviewed; Journal article, 2019)We present a compilation of modern shoreline progradation rates measured close to river outlets entering deltaic coastlines, and we discuss how these observations relate to the overall evolution of both modern and ancient ... -
The Svalbard Eocene-Oligocene (?) Central Basin succession: Sedimentation patterns and controls
Helland-Hansen, William; Grundvåg, Sten-Andreas (Journal article; Peer reviewed, 2021)A synthesis has been undertaken based on regionally compiled data from the post early Eocene foreland basin succession of Svalbard. The aim has been to generate an updated depositional model and link this to controlling ... -
Turbidites in the Eocene of Spitsbergen: can they tell us something about the Sørvestsnaget Basin?
Grundvåg, Sten-Andreas; Helland-Hansen, William; Safronova, Polina (Conference object, 2017) -
Using climate to relate water-discharge and area in modern and ancient catchments
Eide, Christian Haug; Muller, Reidar; Helland-Hansen, William (Peer reviewed; Journal article, 2018-06)Models relating sediment supply to catchment properties are important in order to use the geological record to deduce landscape evolution and interplay between tectonics and climate. Water-discharge (Qw) is an important ...
