Platform Description

The Global Irminger Sea array has two identical Flanking Moorings that make up the equidistant sides of a triangle of Moorings (20 km) from the co-located Profiler and Surface Moorings.  They are located in 2,800 meters of water southeast of Greenland in the North Atlantic.  The triangular configuration moorings provide unique spatial array through which instruments fixed to moorings continuously collect data through time and gliders sample the area between the moorings. The Irminger Sea site is one of four high latitude open ocean locations in the OOI that provide observations to gain better insight into global ocean circulation and climate.

Like other Flanking Subsurface Moorings, the Irminger Sea Flanking Subsurface Moorings contain instruments fixed at specific depths along the mooring riser throughout the water column to a depth of 2,600 meters. The flotation buoy for these subsurface moorings is located 30 meters below the sea surface. As they have no surface expression, these moorings communicate and send data to shore via an acoustic link to nearby gliders.

The Station Papa array has two identical Flanking Moorings that make up the equidistant sides of a triangle of Moorings (40 km) from the co-located Profiler and Surface Moorings. They are located in 4,250 meters in the Gulf of Alaska in the NE Pacific.

Platform Description

The Southern Hydrate Summit 1 Seafloor study site, situated on the continental slope off the coast of Oregon at a water depth of ~ 775 m, hosts abundant deposits of methane ice (methane hydrates) that are buried beneath, and sometime exposed at the seafloor. The deposits vent methane-rich fluids and bubbles that escape through seeps on the ocean bottom. At Southern Hydrate Ridge plumes of bubbles rise several hundred meters above the seafloor. Dense and fascinating communities of microbes and animals with symbiotic microbes in their guts are fueled by these escaping gases.  These seeps provide a unique opportunity to study ocean chemistry, quantifying chemical fluxes from the seafloor and the impacts of methane release on overlying seawater and biota.

Methane is a powerful greenhouse gas and, therefore, quantifying the flux of methane from the seafloor into the hydrosphere is critical to understanding carbon-cycle dynamics and the impacts of global warming on methane release, particularly in the context of the hydrates response to seismic events.

This Low-Power JBox (LJ01B) rests on the seafloor and contains geophysical and near seafloor water column instrumentation, and is attached to a fiber-optic cable. Instrumentation hosted on the JBox is largely geophysical in nature, hosting both short-period and broadband seismometers. The fiber-optic cable provides the JBox with significant power and 1 Gb communication bandwidth for two-way communication to instruments for their operation and transmission of data to shore. This JBox is also co-located with a Medium-Power JBox that collects a complementary suite of seafloor and water column measurements.

Platform Description

The ASHES hydrothermal field is located near the base of the western caldera wall of Axial Seamount at a water depth of 1552 m. It hosts numerous active hydrothermal sulfide chimneys, myriad lower temperature diffuse flow sites, and abundant vent biota. The focused study area is at the ~ 4 m tall actively venting sulfide chimney called “Mushroom” and a diffuse flow site adjacent to the base of the chimney. Instrumentation at this site is focused on understanding linkages between local and far-field seismic events on fluid chemistry and temperature, chimney evolution, and impacts on vent biota.

Seafloor instruments at the ASHES site are attached to a Medium-Power J-Box (MJ03B) through a series of extension cables. An ~ 4 km long extension cable from Primary Node PN03B provides the JBox with significant power (375 v) and bandwidth (1 Gbs) to operate the instruments and transmit data to shore. In addition to geophysical and temperature monitoring instrumentation attached the MJ03B JBox, the site also hosts a high definition video camera, linked to shore via a separate fiber optic cable that provides 10 Gb bandwidth from PN03B. This allows full resolution video to be transferred in real-time to shore, along with communications for pan and tilt capabilities, as well as lights.

The Axial Base Seafloor platform is located near the base of the Axial Seamount at the far western edge of the Juan de Fuca tectonic plate, at ~2,600 meters water deep. The site contains a Medium-Power JBox (MJ03A) and a Low-Power JBox (LJ03A).

Platform Description

The Axial Base Seafloor site is located near the base of the Axial Seamount at the far western edge of the Juan de Fuca tectonic plate, at ~2,600 meters water deep. The site contains a Medium-Power JBox (MJ03A) and a Low-Power JBox (LJ03A). Axial Seamount is the largest and most magmatically robust volcano on the Juan de Fuca Ridge. Axial Seamount is far from the continental shelf (>350 km) and represents an open-ocean or pelagic site in the continuum of observing scales represented in the OOI’s Cabled Array. Here, large-scale currents including the North Pacific Current, the subpolar gyre and the northern end of the California Current interact. These currents transport heat, salt, oxygen, and biota, all of which are crucial to the region’s ecosystem. However, their variability arises from forcing as varied as tides and winds to interannual (El Niño) to decadal (Pacific Decadal Oscillation) timescales.

As with other JBoxes, these rests on the seafloor, contain geophysical and near seafloor water column instrumentation, and are attached to a fiber-optic cable. The fiber-optic cable provides the JBoxes with a significant power and 1 Gb communication bandwidth that provides two-way communication to instruments for their operation and transmission of data to shore. This seafloor site is co-located with a Deep and Shallow Profiler Mooring, which collect complementary water column data.

The Axial Base Deep Profiler Mooring located near the base of the Axial Seamount at the far western edge of the Juan de Fuca tectonic plate, at ~2,600 meters water deep. Axial Seamount is the largest and most magmatically robust volcano on the Juan de Fuca Ridge.

However, their variability arises from forcing as varied as tides and winds to interannual (El Niño) to decadal (Pacific Decadal Oscillation) timescales. Because of its close proximity to the magmatically active volcano, instruments on the profiler may also capture perturbed water masses resulting from underwater eruptions at the summit and along the flanks.

As with other Cabled Deep Profiler Moorings, this mooring contains a Wire-Following Profiler that transmits data both through WiFi, as well as through an inductive link at its basal docking station that is connected to the cable.  The Wire-Following Profiler hosts six instruments and moves through the water column along the mooring cable, continuously sampling ocean characteristics over a specified depth interval (150 meters below sea surface to near bottom).  The fiber-optic cable provides the mooring with significant power and bandwidth and is co-located with a Low-Power Jbox, that collects complementary water property data.
