abstract = {The export of neritic material from the top of carbonate platforms is a key process
in the construction of their slopes. However, our knowledge of the supply pattern
of materials from platforms is dominantly based on platforms lying in the
euphotic zone during the present sea-level
highstand. This is a somewhat biased
perspective as through geological time not all platforms were euphotic. The Saya
de Malha Bank in the Mascarene Plateau is an example of a modern mesophotic
carbonate platform, and as such, its flooding and export patterns differ from those
of euphotic ones. Using cores collected on the western slope of the Saya de Malha
Bank, the export patterns of the platform since the last glacial maximum were
explored. Material on the platform edge is winnowed and transported to the slope
by multiple possible processes. The material on the platform is a combination of
high and low magnesium calcite as well as high and low strontium aragonite,
integrating pelagic and neritic sources. The ratio of these constituents varies over
time with changes in the platform production capability as it was flooded and
drowned during the Holocene transgression. The material from the platform is
transported in both confined flows, mainly during lowstands, and unconfined
flows, mainly during late transgression and early highstand. In the present state
of the highstand, supply may have diminished, leading to erosion of the canyon
shoulders.},
