  Many of the most sensitive physics experiments searching for rare events,
like neutrinoless double beta ($0\nu\beta\beta$) decay and dark matter
interactions, rely on cryogenic macro-calorimeters operating at the mK-scale.
Located underground at the Gran Sasso National Laboratory (LNGS), in central
Italy, CUORE (Cryogenic Underground Observatory for Rare Events) is one of the
leading experiments for the search of $0\nu\beta\beta$ decay, implementing the
low-temperature calorimetric technology. We present a novel multi-detector
analysis to correlate environmental phenomena with the low-frequency noise of
low-temperature calorimeters. Indeed, the correlation of marine and seismic
data with data from a pair of CUORE detectors indicates that cryogenic
detectors are sensitive not only to intense vibrations generated by
earthquakes, but also to the much fainter vibrations induced by marine
microseisms in the Mediterranean Sea due to the motion of sea waves. Proving
that cryogenic macro-calorimeters are sensitive to such environmental sources
of noise opens the possibility of studying their impact on the detectors
physics-case sensitivity. Moreover, this study could pave the road for
technology developments dedicated to the mitigation of the noise induced by
marine microseisms, from which the entire community of cryogenic calorimeters
can benefit.
