Recent licensing rounds in offshore Mozambique have sparked interest in sediment routing histories and the potential for discoveries analogous to those in the Rovuma area. When evaluating clastic reservoir quality in frontier areas, it is important to take the provenance of the detrital sands into consideration. If the hinterland draining into the...

This paper outlines a novel workflow for utilising hinterland datasets to predict reservoir quality and distribution in frontier exploration regions and applies this methodology to a case study in the Nile Delta. Geochemical data are intersected with drainage areas to derive first-order bulk chemical compositions. Drainage polygons are modified usi...

The relationship between the maximum specific growth rate (μ, d-1) of the coccolithophore Emiliania huxleyi and photon flux density (PFD, μmol photons m-2s-1) was quantified using a combination of quantile regression and culture experiment data from the literature (n = 1387). This relationship, used in ecosystem models incorporating E. huxleyi or c...

The response of the coccolithophore calcite and particulate organic carbon (POC) ratio, also known as the rain ratio, to calcite saturation state (Omega(calcite)) is increasingly being used as an input parameter for modelling ocean feedbacks to changes in atmospheric pCO(2). Previously, this relationship has only been determined from a small number...

A revised estimate of the relationship between the maximum growth rate (mu(max), d(-1)) of Emiliania huxleyi and temperature (T, degrees C) was made using quantile regression and literature data from culture experiments (n = 1415). For modeling E. huxleyi bloom formation and coccolithophore functional group growth rate, this relationship is commonl...

Culture experiments were used to assess the applicability of Emiliania huxleyi coccolith morphology as a palaeo-sea-surface salinity (SSS) proxy. Coccolith morphology was dependent on salinity over a range reflecting present day marine conditions; both coccolith size and the number of coccolith elements increased linearly with increasing salinity....

We analysed the morphology of Emiliania huxleyi from globally distributed plankton samples and demonstrate that the size of E. huxleyi placoliths is highly correlated with in-situ sea surface water salinity. A standard step-wise multiple linear regression analysis was used to link morphological parameters of E. huxleyi to in-situ salinity and in-si...
