Scales of variability of phytoplankton composition and biomass in Algoa Bay, South Africa
… at an Algoa Bay oyster farm. Time series of winds, sea surface temperatures (SSTs) and fluorescence were presented for the period from September/October 2010 to May/June 2012. The time series showed strong seasonal and interannual variability in the winds and SSTs. SSTs ranged from …

The sedimentology and petrology of the new red sandstone of the Elgin Basin, North East Scotland
… from the main Norwegian Basin to the east.To the south of the basin at Elgin, deposition began during the Upper Permian with a series of sheetflood deposits which graded laterally into seif dunes to the north. Deposition during the Triassic is dominated by aeolian barchan dunes although minor …

Environmental variables influencing spatial and temporal patterns of fish spawning and recruitment
… the life cycles of some fish species found off South Africa and Norway were synthesized using data collected from the literature. The comparison of temporal patterns in spawning of South African fish species showed variable spawning times and intensity depending on the environmental conditions …

Statistical relationships between palagic fish catches and long-term series of environmental conditions in the southern Benguela region
… Monthly means of sea surface temperature, north-south wind component, west- east wind component and sea level were used as environmental indices. Over the period 1950 to 1985, annual pilchard catches are found to be negatively correlated to sea surface temperature in the Namaqualand and Agulhas …

Understanding the source and distribution of marine macro-plastics in coastal environments
… facing coastlines (i.e., facing the prevailing south-westerly winds). These findings identified that although the Clyde Sea could be considered a source of pollution to the remote northwest coast, it was at low densities. The next stage was to validate the predictions of the particle tracking …

Tephrostratigraphy, petrography, geochemistry, age and fossil record of the Ganigobis Shale Member and associated glaciomarine deposits of the Dwyka Group, Late Carboniferous, southern Africa
… in argillaceous units of the Dwyka Group in southern Nambia and South Africa which are the earliest witnesses of volcanism in Karoo-equivalent strata of southern Africa. The aim of this study is to present the field appearance of these marker beds, to characterise their mineralogy, …

Palaeoceanographic conditions and palaeoproductivity changes from the sub-Antarctic island South Georgia since the late deglacial, using marine micropalaeontology and geochemistry
… conditions and palaeoproductivity on the South Georgia shelf spanning the late deglacial through the Holocene. South Georgia lies within the path of the Antarctic Circumpolar Current (ACC) and the Southern Hemisphere Westerly Winds (SWW), south of the current position of the Antarctic …
