Missing links in the study of solute and particle exchange between the sea floor and water column

Abstract

factors, which are identified in this review and may be moderated by others, such as currents, granulometry, nutrient and matter inputs, as well as living organisms. In turn, the occurrence of exchanges can influence adjacent environments and organisms. Major gaps in the present knowledge include the temporal and spatial variation in many of the processes driving benthic/pelagic exchange processes and the variability in the relative importance of individual processes caused by this variation. Furthermore the accurate assessment of some anthropogenic impacts is deemed questionable due to a lack of baseline data, and long-term effects of anthropogenic actions are often unknown. It is suggested that future research should be transdisciplinary and at ecosystem level wherever possible, and that baseline surveys should be implemented and long-term observatories established in order to fill the current knowledge gaps.
