During the July 25-August 29, 2017 Regional Cabled Array VISIONS’17 cruise onboard the R/V Roger Revelle using the remotely operated vehicle Jason more than 120 cabled instruments will be recovered and reinstalled on the submarine fiber optic observatory.
During this cruise,
- 6 instrumented science pods on the Shallow Profiler Moorings will be recovered, installed, and tested on the 12 ft across, 7 ton platforms at 200 m water depth as part of the Shallow Profiler Moorings. Each mooring hosts 18 diverse instruments;
- 2 Deep Profiler moorings will be recovered and renstalled, each hosting an instrumented Mclane wire crawler;
- 7 instrumented secondary junction boxes, each hosting an diverse array of instruments were recovered and reinstalled; and
- 2 Benthic Experiment Platforms will be recovered and reinstalled.
CTD water casts to measure ocean parameters, and fluid sampling and analyses of seawater, seep and hydrothermal fluids will be conducted for instrument verification.
Broadband Hydrophone V17
The high-frequency broadband hydrophone may be used to hear noises from oceanic creatures as well as human sources. During VISIONS 14, broadband hydrophones were installed at the Endurance offshore benthic package (LJ01C), nearshore b ...
Dissolved Oxygen Sensor V17
Dissolved oxygen is the most well-known gas in ocean waters, because several types of sensors are commercially available. These include membrane Clark-type cells and optode sensors. The OOI program uses both types of oxygen sensors o ...
Benthic Experiment Package V
The Benthic Experiment Package (BEP) is composed of a hazard-resistant frame, the inside of which hosts an UW-APL-designed Low Power communications housing, and a variety of sensors to measure oceanographic properties that include acidity (pH), ...
Acoustic Doppler Current Pro
An Acoustic Doppler Current Profiler (ADCP) provides a 3D water-current velocity for a small volume of the overlying water column by making very high-frequency acoustic (75- to 600-kHz) doppler shift measurements. These instruments ar ...
Seafloor Pressure Sensor V17
Real-time measurements provided by seafloor pressure sensors are of great importance because lunar tides, storms, and tsunamis strongly impact pressures at the seafloor and the flow of fluids into and out of the oceanic crust. In 2014 ...
Optical Attenuation Sensor V
Optical absorption and attenuation instruments allows total scattering to be derived for living and detrital particles in the ocean. This model is the WET Labs AC-S instrument. During VISIONS '14, optical attenuation sensors were ...
Benthic Flow Meter V17
The benthic flow meter measures the velocity of fluids flowing into and out of the seafloor at methane seep sites, which is critical to determining the amount (flux) of methane, hydrogen sulfide, and other gases that are emitted into the overlyi ...
Horizontal Electrometer Pres
The Horizontal Electrometer-Pressure-Inverted Echosounder (HPIES) is an instrument that utilizes a bottom pressure sensor, a 12-kHz inverted echosounder and a horizontal electrometer to measure the horizontal electrical field, the bottom pressur ...
CTD: Conductivity, Temperatu
A CTD is an instrument used to determine how conductivity (C) and temperature (T) measurements in the ocean vary relative to depth (D) and is a primary tool for measuring physical properties of the ocean. Salinity is determined from electr ...
Osmotic Fluid Sampler
Long term measurements of fluid chemistry are critical to understanding hydrothermal and methane seep environments because this impacts reactions in hydrothermal chimneys and in seep sediments and the associated biota that thrive inside and outs ...
3D Thermistor Array
A custom thermistor array, developed by UW RSN Project Scientist, Giora Proskurowski, includes four stacked triangular arrays with 24 individual temperature measurement points, providing a three-dimensional distribution of temperature. Temperatu ...
Resistivity Probe V17
Known as the "Res Probe," this novel seafloor instrument is designed to go inside the "throats" of high temperature (up to 480°C) black smoker chimneys to measure the resistivity and temperature of the hydrothermal vent ...
Bottom Pressure and Tilt Met
The Bottom Pressure and Tilt Meter (BOPT) is a custom instrument developed by Bill Chadwick at NOAA PMEL in Newport, Oregon The BOPT measures the inflation and deflation of the seafloor at the summit of Axial Seamount using a precision pressure ...
Mass Spectrometer V17
Measurements of dissolved gas concentrations such as carbon dioxide, methane, and hydrogen sulfide are critical to understanding volcanic, chemical, and biological processes in submarine environments. Carbon dioxide in magma chambers helps drive ...
High Definition Video Camera
The high-definition video camera on the OOI RSN cabled system obtains high resolution views of black smoker fluids and coupled biological activity at the Mushroom hydrothermal sulfide chimney within the ASHES hydrothermal field on the western si ...
Digital Still Camera V17
Only very rarely has there ever been long-term (~1-year) imagery taken of methane seep and hydrothermal vent sites, yet the information digital stills provide is crucial to understanding how these venting systems evolve and their linkages to bio ...
Shortperiod Ocean Bottom Sei
Short-period ocean-bottom seismometers (OBSSP) detect vibrations from small earthquakes ranging from 0.1 Hz to 100 Hz. These earthquakes are caused by local phenomena, such as melt movement beneath Axial Seamount and upward flow of hydrothermal ...
Broadband Seismometer V17
Broadband seismometers measure seismicity/earthquake activity along tectonic plate boundaries where key phenomena can occur: large-magnitude subduction zone earthquakes, localize earthquakes associated with faulting and spreading events, and sei ...
Turbulent Flow Current Meter
The VELD3 turbulent water velocity instrument measures how seawater mixes at the small scale. This behavior is important in understanding how hea ...
