A total of 183 core and cutting samples from seven exploratory wells were selected to be analyzed by Rock-Eval pyrolysis. These cores have been drilled through the Lam and Meem Members of the Madbi Formation and contain the major source rocks of Yemen´s sedimentary basins. Contents of total organic carbon were measured and Rock-Eval pyrolysis was performed to evaluate the hydrocarbon potential ...

Large bedforms in the nearshore (with heights of 10 – 50 cm and lengths of 1-10 m) are observed to occur frequently and to be ubiquitous throughout the surf zone (e.g., Clifton et al. 1971, Gallagher et al. 2002, Hay and Wilson 1994, Thornton et al. 1998). However, their dynamics are poorly understood and they are generally neglected in models of sediment transport, morphology change and nearsh...

In this study, we investigate phosphorus (P) and iron (Fe) cycling in sediments along a depth transect from within to well below the oxygen minimum zone (OMZ) in the northern Arabian Sea (Murray Ridge). Pore-water and solid-phase analyses show that authigenic formation of calcium phosphate minerals (Ca-P) is largely restricted to where the OMZ intersects the seafloor topography, likely due to h...
