1) Acquire multichannel seismic reflection data on
Kermadec arc ridges, including a pseudo-3-
dimensional experiment on Brothers Volcano; 2)
Collect multibeam echo-sounder data – including the
entire water column - over seamounts and rifts; 3)
Collect rock and biological specimens from Havre
Trough rifts. The data will be used to develop models
for the formation of the Kermadec arc and rifting of
the Havre Trough, and to assess the biota of deep
rifts.
To test hypotheses relating to hydrothermal
emissions and associated chemosynthetic faunas on
the Mid-Cayman Rise. This is the deepest known
seafloor seafloor spreading centre and is located in a
poorly ventilated and geographically isolated deep
ocean basin. It specifically targets a region identified
as a priority for investigation by the International
Census of Marine Life to advance the understanding
of global vent biogeography. In addition, its unique
samples will provide resources for the wider marine
biotechnology and microbial metagenomics research
communities.
To investigate the effects of hydrothermal circulation
on both the geophysics and oceanography in the
Panama Basin.
Investigating biogeochemical cycling in the South
EPR hydrothermal plume (as well as Peru upwelling).
