numerous pelagic organisms, most of which are able to emit light. {H}ere we present a unique data set consisting of a 2.5-year long record of light emission by deep-sea pelagic organisms, measured from {D}ecember 2007 to {J}une 2010 at the {ANTARES} underwater neutrino telescope in the deep {NW} {M}editerranean {S}ea, jointly with synchronous hydrological records. {T}his is the longest continuous time-series of deep-sea bioluminescence ever recorded. {O}ur record reveals several weeks long, seasonal bioluminescence blooms with light intensity up to two orders of magnitude higher than background values, which correlate to changes in the properties of deep waters. {S}uch changes are triggered by the winter cooling and evaporation experienced by the upper ocean layer in the {G}ulf of {L}ion that leads to the formation and subsequent sinking of dense water through a process known as "open-sea convection". {I}t episodically renews the deep water of the study area and conveys fresh organic matter that fuels the deep ecosystems. {L}uminous bacteria most likely are the main contributors to the observed deep-sea bioluminescence blooms. {O}ur observations demonstrate a consistent and rapid connection between deep open-sea convection and bathypelagic biological activity, as expressed by bioluminescence. {I}n a setting where dense water formation events are likely to decline under global warming scenarios enhancing ocean stratification, in situ observatories become essential as environmental sentinels for the monitoring and understanding of deep-sea ecosystem
