We reconstruct a Plio-Pleistocene microscopic tephrostratigraphy for DSDP Site 231 in the Gulf of Aden. Systematic microtephrostratigraphy increases the potential for identifying tephra horizons for regional stratigraphic correlation and age control, as well as providing information about eruptive histories. Microtephra reveal three main pulses of volcanism c. 4.0–3.2 Ma, 2.4 Ma and 1.7–1.3 Ma,...
Stylophora pistillata is a widely used coral "lab-rat" species with highly variable morphology and a broad biogeographic range (Red Sea to western central Pacific). Here we show, by analysing Cytochorme Oxidase I sequences, from 241 samples across this range, that this taxon in fact comprises four deeply divergent clades corresponding to the Pacific-Western Australia, Chagos-Madagascar-South Af...
1 The 5,000-nautical mile (nmi) coastline of the wider Gulf of Guinea offers seemingly idyllic conditions for shipping. It is host to numerous natural harbors and is largely devoid of chokepoints and extreme weather conditions. It is also rich in hydrocarbons, fish, and other resources. These attributes provide immense potential for maritime commerce, resource extraction, shipping, and developm...
The study presents geologic investigation of Yemen and the Gulf Aden with a special focus on geophysical, seismic, tectonic topographic mapping performed by integrated approach QGIS GMT scripting. Cartographic visualization is crucial in analysis, data processing prognosis mineral resource prospects. region was formed as result Arabian African plates movements still tectonically active. Besides...
Symphysanodon andersoni was described in 1974 from a single specimen collected southwest of Socotra Island, near the entrance to the Gulf of Aden. A more recent report (2003) of its capture in the Gulf of Kutch, Arabian Sea, was based on a misidentification. The second known specimen of the Bucktoothed Slopefish, S. andersoni, (at 204 mm SL the largest known specimen of the genus Symphysanodon)...
Four new species are assigned to the genus Teretia Norman, 1888 in the family Raphitomidae Bellardi, 1875 and herein described: Teretia neocaledonica sp. nov., T. sysoevi sp. nov., T. tongaensis sp. nov. from the southeastern Pacific and Teretia tavianii sp. nov. from the Gulf of Aden. The new species represent the first Indo-Pacific record of a genus previously known in the recent molluscan fa...
