The Impact of Fine-Scale Currents on Biogeochemical Cycles in a Changing Ocean.

Fine-scale currents, (1-100 km, days-months), are actively involved in the transport and transformation of biogeochemical tracers in the ocean. However, their overall impact on large-scale biogeochemical cycling on the timescale of years remains poorly understood due to the multiscale nature of the problem. Here, we summarize these impacts and critically review current estimates.
