All sites from all global ORION conceptual
proposals in 2005. The 3 most coordinated
proposals were derived from OceanSITES efforts.

• CRITERIA used for site selections
• high value and impact to many disciplines
• building a NETWORK, not just collection of
  single sites
• review process/results
• contribution to acoustic network on basin-scale
  (either complete or to leverage additional
  acoustic sites)
• avoid very remote locations since shiptime has
  to come from OOI
• use SPAR buoys only where really necessary for
  the science
• use acoustic rather than EOM moorings where
  sufficient (saves hardware, ROV, shiptime and
  shipsize)
• BUT
• want to demonstrate and gain experience with EOM
  moorings early in the project
• have at least 1 mid-latitude SPAR site
• reach the goal of 1 high-latitude SPAR site
  toward end of period

• PHASING
• Start with small number of sites that can
  demonstrate early in the project the capabilities
  being built, the technologies available, the
  value and impact also with sites that can give
  guidance for future developments (gathering
  experience).
• No SPAR technology available so early in project.
• Most sites need a surface mooring for
  communication with seafloor network, possibly
  power, met sensors, PLUS a subsurface mooring
  with biogeochemical profilers in upper ocean, and
  a modest seafloor network.
• 5 of the most highly ranked multi-community
  interest sites one mid-latitude, one
  high-latitude, one EOM, one with established
  timeseries and infrastructure, one with
  international coordination

EOM
Total capital and install cost estimate 10Mio

• Over following years, phase in additional sites
• only 1 intensive RIDGE type seafloor network
  with SPAR buoy can be afforded. Offer 6Mio
  to RIDGE community for ONE site, either Lucky
  Strike (Mid Atlantic Ridge), or 9N (East Pacific
  Rise)
• install a high-latitude SPAR at Southern Ocean
  Site off Chile (high-priority site for many
  communities) and move the acoustic discus
  mooring from there to western South Pacific
• complete Pacific Basin network and expand North
  Atlantic, taking into account European efforts
  there

OceanSITES action - Note no transport sites,
those fit better into NOAA interests - how much
can locations be moved for optimizing acoustic
paths - where is international coordination
necessary/desirable ? How ? (purposely left
out sites with dominating presence by other
countries, e.g. PAP, but also included some where
coordination is desirable/expected like
equatorial Atlantic, Irminger Sea) - any
feedback on the process/proposal ?
