  abstract = {{F}ine-scale currents, {O}(1-100 km, days-months), are actively involved in the transport and transformation of biogeochemical tracers in the ocean. {H}owever, their overall impact on large-scale biogeochemical cycling on the timescale of years remains poorly understood due to the multiscale nature of the problem. {H}ere, we summarize these impacts and critically review current estimates.{W}e examine how eddy fluxes and upscale connections enter into the large-scale balance of biogeochemical tracers. {W}e show that the overall contribution of eddy fluxes to primary production and carbon export may not be as large as it is for oxygen ventilation. {W}e highlight the importance of fine scales to low-frequency natural variability through upscale connections and show that they may also buffer the negative effects of climate change on the functioning of biogeochemical cycles. {S}ignificant interdisciplinary efforts are needed to properly account for the cross-scale effects of fine scales on biogeochemical cycles in climate projections.},
