A climatic trigger for the giant Troll pockmark field in the northern North Sea
Mazzini, Adriano; Svensen, Henrik; Forsberg, Carl Fredrik; Linge, Henriette; Lauritzen, Stein-Erik; Haflidason, Haflidi; Hammer, Øyvind; Planke, Sverre; Tjelta, Tor-Inge (Peer reviewed; Journal article, 2017-04)Pockmarks are seafloor craters usually formed during methane release on continental margins. However, the mechanisms behind their formation and dynamics remain elusive. Here we report detailed investigations on one of the ... -
Delimiting morphological and volumetric elements of cave surveys as analogues for paleokarst reservoir modelling – A case study from the Maaras cave system, northern Greece
Lønøy, Bjarte; Pennos, Christos; Tveranger, Jan; Fikos, Ilias; Vargemezis, George; Lauritzen, Stein-Erik (Journal article; Peer reviewed, 2021)Active karst systems can offer good analogues for paleokarst reservoir modelling as they can provide links between present karst system geometries and the final reservoir architecture. Although clastic sediments are a ... -
Detecting multiscale karst features including hidden caves using microgravimetry in a Caledonian nappe setting: Mefjell massif, Norway.
Solbakk, Terje; Fichler, Christine; Wheeler, Walter H; Lauritzen, Stein-Erik; Ringrose, Philip (Peer reviewed; Journal article, 2018-11-20)Cave passages and karst features form negative density contrasts expressed in gravity field anomalies. We present an interpretation approach for microgravimetry, applicable for challenging geological settings with heterogeneous ... -
Geocellular rendering of cave surveys in paleokarst reservoir models
Lønøy, Bjarte; Tveranger, Jan; Pennos, Christos; Whitaker, Fiona; Lauritzen, Stein-Erik (Journal article; Peer reviewed, 2020)Infilled and collapsed cave systems are an important component of many paleokarst reservoirs. Incorporating these features into industrial reservoir models commonly relies on geostatistical modelling methods that often ... -
Morphology and life history divergence in cave and surface populations of Gammarus lacustris (L.)
Østbye, Kjartan; Østbye, Eivind; Lien, Anne May; Lee, Laura R.; Lauritzen, Stein-Erik; Carlini, David B. (Peer reviewed; Journal article, 2018-10-25)Cave animals provide a unique opportunity to study contrasts in phenotype and life history in strikingly different environments when compared to surface populations, potentially related to natural selection. As such, we ...
