The biological productivity of the ocean
The biological productivity of the ocean
Reconstructions of ocean productivity using sediment records typically involve the accumulation of biogenic matter (organics or mineral hard parts) in the sediment; therefore, these studies speak to export production rather than NPP. However, if export production is reconstructed, it is at least a fair assumption that NPP would have changed in the same direction. Moreover, as described below, the export of organic matter out of the surface ocean can have broad biogeochemical and climate implications, so reconstructing export production is valuable in itself. One of the greatest challenges for reconstructing ocean productivity is the potential for changes in the fraction of export production that reaches the seabed and is preserved into the sediments, which could be misinterpreted as changes in productivity. The development and improvement of such reconstructions is an active area of research.

Abstract
Reconstructions of ocean productivity using sediment records typically involve the accumulation of biogenic matter (organics or mineral hard parts) in the sediment; therefore, these studies speak to export production rather than NPP. However, if export production is reconstructed, it is at least a fair assumption that NPP would have changed in the same direction. Moreover, as described below, the export of organic matter out of the surface ocean can have broad biogeochemical and climate implications, so reconstructing export production is valuable in itself. One of the greatest challenges for reconstructing ocean productivity is the potential for changes in the fraction of export production that reaches the seabed and is preserved into the sediments, which could be misinterpreted as changes in productivity. The development and improvement of such reconstructions is an active area of research.
