Biological and environmental rhythms in (dark) deep-sea hydrothermal ecosystems
During 2011, two deep-sea observatories focusing on hydrothermal vent ecology were up and running in the Atlantic (Eiffel Tower, Lucky Strike vent field) and the Northeast Pacific Ocean (NEP) (Grotto, Main Endeavour Field). Both ecological modules recorded imagery and environmental variables join...

| description | During 2011, two deep-sea observatories focusing on hydrothermal vent ecology
were up and running in the Atlantic (Eiffel Tower, Lucky Strike vent field)
and the Northeast Pacific Ocean (NEP) (Grotto, Main Endeavour Field). Both
ecological modules recorded imagery and environmental variables jointly for a
time span of 23 days (7–30 October 2011) and environmental variables for up
to 9 months (October 2011–June 2012). Community dynamics were assessed based
on imagery analysis and rhythms in temporal variation for both fauna and
environment were revealed. Tidal rhythms were found to be at play in the two
settings and were most visible in temperature and tubeworm appearances (at
NEP). A ∼ 6 h lag in tidal rhythm occurrence was observed between
Pacific and Atlantic hydrothermal vents, which corresponds to the
geographical distance and time delay between the two sites. |
