NEPTUNE Canada

Main Endeavour vent field

• water sampler (RAS) with attached temperature sensor
• benthic and resistivity sensors (BARS) and temperature probe
• Tempo-mini, which integrates the following instruments on a single platform:
  • video camera with LED lights and anti-biofouling devices
  • temperature probes
  • Aanderaa optode oxygen sensor
  • CHEMINI (total Fe) system
• Cabled Observatory Imaging Sonar System (COVIS)
• short-period seismometer

Mothra hydrothermal vent field (planned)

• microbial incubator
• benthic and resistivity sensors (BARS)
• short-period seismometer

Regional circulation moorings

Installed: Northeast, Northwest

Planned: South, Southwest

Four regional circulation moorings, each including:

• ADCP (75 kHz)
• current meters
• CTD

A bottom pressure recorder, part of the West Coast "tsunami-meter" experiment, is also positioned near the northeast regional circulation mooring.

Seismicity study site (planned)

• broadband seismometer (360s - 50Hz)
• strong motion accelerometer
• current meter
• differential pressure sensor

Seismometer network

In addition to this seismicity study site, seismometers will be installed across the Endeavour study area:

Short-period seismometer locations

• main Endeavour vent field
• near the northeast regional circulation mooring

Standard seismometer locations

• Mothra vent field
• approximately 500m east of the node

Differential Pressure within the Sediment

• piezometer

ODP 1027 Instrument Platform

• broadband seismometer (360s - 50 Hz)
• Conductivity Temperature Depth (CTD) gauge

ODP 1027 Seismometer Auxiliary Platform

• acoustic current meter
• differential pressure gauge

ODP Borehole 1026B

• CORK pressure sensor
• CORK temperature sensor

ODP Borehole 1027 (planned)

• CORK pressure sensor

• controlled source electromagnetic (CSEM) system
• broadband seismometer
• bottom pressure recorder (BPR)
• CTD
