    Changes in lipid content, lipid class composition and fatty acid composition of developing eggs and unfed larvae of cod (Gadus morhua) (1988)

    Notes: Abstract Changes in the lipid class and fatty acid composition of developing eggs and unfed larvae of cod (Gadus morhua L.) were studied with the objective of determining probable requirements of cod larvae for dietary lipid. The eggs were collected on 24 March 1985 from holding tanks containing cod which had been caught off the northwest coast of Scotland. Phosphatidylcholine (PC) was the only lipid class to decline in absolute terms during embryogenesis. Catabolism of neutral lipid was initiated during the first week after hatching, and the rate of neutral lipid utilisation increased after the larvae had completely absorbed their yolk sacs. The quantity of triacylglycerol (TAG) remained constant during embryogenesis, but the percentage of 22:6(n-3) int TAG increased substantially during this period. It was calculated that ca. 33% of the 22:6(m-3) released during the process of PC catabolism was incorporated into TAG and sterol ester. The results suggest that PC, replete in appropriate essential fatty acids, should represent a major proportion of the lipid in artificial diets for fish and crustacean larvae.

    Seasonal changes in sedimentation of particulate matter and lipid content of zooplankton collected by sediment trap in the Arctic Ocean off Axel Heiberg Island (1989)

    Notes: Summary Sedimentation of particulate matter measured at a depth of 100 m varied from 0.2 to 6.0 mg dry weight m-2 d-1 over approximately monthly intervals between September 1986 and June 1987 on the continental shelf of the western Arctic Ocean north of the Canadian Arctic Islands. Detritus deposited during December and January, the period of maximum sedimentation, contained relatively low amounts of organic carbon and nitrogen (4.0% and 0.5% of dry weight, respectively) with a carbon: nitrogen ratio 〉 7. Maximum rates of organic carbon and nitrogen sedimentation (0.60 and 0.12 mg m-2 d-1, respectively) during February were associated with debris enriched with organic matter (organic carbon and nitrogen content of 17.0% and 3.4% of dry weight, C:N=5). Dry weight of macrozooplankton, predominantly Calanus hyperboreus and Metridia longa, separated from preserved trap contents, equalled or exceeded by up to an order-of-magnitude the weight of sedimented debris. Lipid content of CV and adult female stages of C. hyperboreus decreased from 46%–64% of dry weight in September to 20%–30% in January. Females of C. hyperboreus with lower lipid levels (7% of dry weight) between April and June were probably in a post-reproductive condition.

    The impact of the Messinian salinity crisis on the petroleum system of the Eastern Mediterranean: a critical assessment using 2D petroleum system modelling (2016)
    Geological Society of London
    Details
    Publication Date: 2016-10-15
    Description: The offshore Levant Basin demonstrates one of the most phenomenal natural examples of a working petroleum system associated with a relatively rapid unloading and loading cycle caused by the Messinian salinity crisis (MSC). In this study, 2D basin and petroleum systems modelling suggests that the geologically instantaneous water unloading of approximately 2070 m, and subsequent rapid salt deposition and refill, impact the subsurface pore pressure and temperature in the underlying sediments. The pressure drop is modelled to be instantaneous, whereas the impact on temperature is more of a transient response. This has important consequences for the shallow sub-Messinian biogenic petroleum system, which is assumed to have experienced fluid brecciation associated with massive fluid escape events. Deeper Oligo-Miocene sediments are far less affected, thus indicating a ‘preservation window’ for biogenic gas accumulations, which host the recent discoveries (Tamar, Leviathan, Aphrodite). Hydrocarbon accumulations of a ‘bubblepoint oil’ composition are modelled to have experienced cap expansion during the drawdown, with the pressure drop being the primary control. This study suggests that seal-limited traps are expected to have undergone a catastrophic seal failure, whereas the impact of the MSC is modelled to be less destructive for size-limited and, particularly, charge-limited traps.

    Gravity-driven deformation of a youthful saline giant: the interplay between gliding and spreading in the Messinian basins of the Eastern Mediterranean (2016)
    Geological Society of London
    Details
    Publication Date: 2016-10-15
    Description: The triggers and drivers for salt-related deformation on continental margins are intensely debated, reflecting uncertainties regarding the diagnostic value of certain structural styles, in addition to the fundamental mechanics associated with the two principal mechanisms (gliding and spreading). Determining the triggers and drivers for salt-related deformation is important because they provide insights into continent-scale geodynamic processes, the regional kinematics of gravity-driven deformation, and sediment dispersal and hydrocarbon prospectivity. The processes associated with and the timing of deformation of Messinian salt in the offshore Eastern Mediterranean are uncertain, and thus so is our understanding of the geodynamic evolution of this tectonically complex region. We here use an extensive 2D and 3D seismic reflection dataset to test models for the salt-tectonic development of Messinian salt. We contend that gliding and spreading were not mutually exclusive, but were likely to have overlapped in time and space, being associated with local and far-field tectonics (gliding), as well as differential overburden loading (spreading). We also argue that intrasalt strain and seismic-stratigraphic patterns can be explained by a model invoking a single, post-Messinian period of salt-related deformation, rather than a more complex model involving two separate deformation events that occurred during and after salt deposition.
