blow-downs do not occur. These come from the spectral cusps, unambiguously representing incoherent internal tides.
In the MC case we visually inspected all time-series, see Fig. 4. We compare
neighbouring instruments to elucidate whether the disruption of the ‘string of pearls’
was actually due to a blow-down event or to some other phenomenon. We were particularly cautious in not removing those phenomena since they introduce natural variability we do not want to remove from our time-series. See for example panel (f) in
Fig. 4. Compare events at mooring lmc8 during July and August of 2008 (not marked
as NaN) with those during February and March of 2009 (marked as NaN). At first
sight one could say both disruptions of the ‘string of pearls’ are due to a blow-down
event, but taking a closer look one realises they are not. The marked events involve
