title: International District Vent Field 1

description: The International District Vent Field 1 Medium-Power Junction Box (MJ03C) supports instruments to investigate the chemistry and temperatures of high temperature and diffuse flow vent sites within the International District Hydrothermal Field located along the eastern rift zone of Axial Seamount at a water depth of ~1,520 meters. Axial Seamount on the Juan de Fuca spreading center is an optimal site for a long-term observatory, as it is the most magmatically robust volcano on the spreading center and only one day by ship from the Washington and Oregon coasts. Additionally, the caldera hosts numerous active hydrothermal fields and abundant sites of diffuse flow. The main study sites include the actively venting chimneys called El Gordo, Escargot, and Diva. The El Gordo site also hosts a digital still camera and microbial DNA sampler. Coupled with the geophysical array on the summit of Axial Seamount, these instruments are designed to better understand linkages between seismicity, fluid temperatures and chemistry, and the evolution of biological communities over time in highly dynamic environment commonly perturbed by volcanic eruptions. A ~2.2 km-long electro-optical cable from Primary Node PN03B provides the junction box with significant power (375 V) and bandwidth (1 Gbs) to operate the instruments and transmit data to shore.

title: Eastern Caldera

description: The Eastern Caldera Medium-Power Junction Box (MJ03E) supports geophysical instruments in the Eastern side of the 3-km-across caldera at the summit of Axial Seamount, at a water depth of ~1,520 meters. The instruments are designed to measure local seismic events associated with migration of melt and volatiles within the volcano, as well as far-field seismic events. They also measure uplift and deflation of the seafloor associated with ingress of melt within the underlying magma chamber, and collapse of the seafloor during diking-eruptive events. This site was chosen because Axial has erupted in 1988, 2011, and again in 2015. During the 2015 event, over 8,000 earthquakes were measured with the cabled geophysical array, and data were streamed live back to shore in real-time. A 635 meter-long electro-optical cable from Primary Node PN03B provides the junction box with significant power (375 V) and bandwidth (1 Gbs) to operate the instruments and transmit data to shore.

title: Single- and Double-Layer Potential Matrices

description: These files contain precomputed single- and double-layer potential matrices used in the 2D wave scattering examples for the jaxhps package. These matrices are used to discretize a boundary integral equation which simulates the Sommerfeld radiation condition. See https://arxiv.org/abs/2503.17535 for more details.

After unzipping the folder, you will see files with filenames like SD_k{kval}_n{nval}_nside{nsideval}_dom1.mat. Each file contains S and D matrices for a particular discretization and wavenumber. The files are saved in MATLAB file format. The values in these filenames are:



kval is the wavenumber for the Helmholtz problem. The forward scattering example in the jaxhps package uses kval=100, and the inverse scattering example uses kval=20. 

nval corresponds to the order of the Gauss panels used in the HPS discretization. The HPS method uses a quadtree to discretize the spatial domain, and each leaf in the quadtree has an order nval discretization on each side.

nsideval corresponds to the number of leaves along a side of the domain. A quadtree with depth L will have 2^L leaves along each side.


 

Once downloaded, you can run the 2D wave scattering examples and specify a discretization level and wavenumber; the example scripts will automatically load the correct file.

title: Mechanisms of copper and zinc bioremoval by microalgae and bacteria grown in nutrient rich wastewaters

description: Swine farming produces large quantities of nutrient-rich wastewater, which often contains metals such as Cu and Zn, used as feed additives for pigs. These metals must be removed from the wastewater before discharge but their retention in the biomass can limit its subsequent utilization. Photobioreactors are a very promising alternative for swine wastewater treatment, as the consortium of microalgae and bacteria growing symbiotically in these reactors allows high nutrient and metal removal efficiency at moderate costs. This work studies the mechanisms of removal of Cu(II) and Zn(II) by the two types of microorganisms growing in these photobioreactors. A microalga commonly used in wastewater treatment (Scenedesmus almeriensis) and an activated sludge were kept in contact with synthetic wastewater containing 100 mg/L of Cu and Zn. After 72 h, Scenedesmus almeriensis removed 43% of Cu and 45% of Zn, while activated sludge removed 78% of Cu and 96% of Zn. Single and sequential extractions of the biomasses using different extracting reagents revealed that biosorption on protonable groups is the dominant removal mechanisms. Mild reagents solubilized 69% of Cu and 94% of Zn from the microalgae and 76% of Cu and 93% of Zn from the activated sludge. Low metal concentrations in the oxidizable and residual fractions evidenced minimal bioaccumulation inside the cells. FTIR and ESEM-EDX analysis confirmed biosorption by ion exchange and complexation as the main metal remediation mechanisms. The weak bonds of the biosorbed Cu and Zn ions are beneficial for the valorization of biomass and the obtaining of safe bioproducts.

title: Axial Base Shallow Profiler Mooring

description: The Axial Base Shallow 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, ~350 km from the continental shelf, and represents an open-ocean or pelagic site in the continuum of observing scales represented in the Regional 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. Their variability ranges across timescales from daily tides to seasonal winds to interannual El Niño events to Pacific Decadal Oscillations. 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. This mooring contains a Shallow Profiler (SF01A) and Platform Interface Controller (PC01A), hosted on a 12 ft across, 7 ton platform connected to the fiber-optic cable. The Shallow Profiler houses 10 scientific instruments and is tethered to a winch that pays out fiber optic cable allowing the profiler to rise through the water column until a fixed depth below the oceans surface, determined by currents and wave conditions at the surface. Eight instruments are also housed within the Platform Interface Controller mounted 200 m below the sea surface on the mooring platform. The electro-optical cable provides the mooring with power and 10 Gb communication bandwidth and is co-located with a Low-Power junction box that collects complementary geophysical and near-seafloor water property data.

This mooring contains a Wire-Following Profiler that hosts six scientific instruments and moves through the water column along the mooring riser, continuously sampling ocean characteristics over a specified depth interval (150 meters below sea surface to near bottom) and is connected to an electro-optical cable that provides a large supply of power and bandwidth. The Axial Base Deep Profiler Mooring is co-located with a Low-Power junction box that collects complementary geophysical and near-seafloor water property data.

title: Ashes Vent Field

description: The ASHES hydrothermal field is located near the base of the western caldera wall of Axial Seamount at a water depth of 1,552 meters. 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 junction box (MJ03B) through a series of electro-optical cables. A ~4 km long extension cable from Primary Node PN03B provides 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 to MJ03B, the site also hosts a high-definition video camera linked to shore via a separate 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 the lights and pan-and-tilt capabilities.

title: Southern Hydrate Summit 2 Seafloor

description: The Southern Hydrate Summit 2 Seafloor study site, situated on the continental slope off the coast of Oregon at a water depth of ~775 meters, hosts abundant deposits of gas hydrates (methane ice) 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 and can rise in plumes several hundred meters above the seafloor, also fueling dense communities of microbes and animals with chemosynthetic symbiotes. These seeps provide a unique opportunity to study ocean chemistry, quantify chemical fluxes from the seafloor, and observe 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 following seismic events. This Medium-Power junction box (MJ01B) rests on the seafloor adjacent to a highly active methane seep called Einstein’s Grotto. Instrumentation at this site is designed to monitor chemistry of the seep, image the seep and associated biota in detail, and image the bubble plume as it rises several hundred meters above the seafloor. This junction box is attached to an electro-optical cable that provides significant power and 1 Gb two-way communications bandwidth, and is co-located with a Low-Power junction box that collects a complementary suite of geophysical and near-seafloor water column measurements.

title: Oregon Slope Base Seafloor

description: The Oregon Slope Base Seafloor site is located adjacent to the continental slope off the coast of Oregon at a water depth of ~2,900 meters. The site contains a Medium-Power junction box (MJ01A) and a Low-Power junction box (LJ01A). Here, ocean water properties are profoundly impacted by the California Current and internal waves. The coastal region of the Pacific Northwest is a classic wind-driven upwelling system where nutrient-rich deep waters rise to replace warmer surface waters, resulting in high marine productivity that attracts zooplankton, fish, and marine mammals. Near-bottom fauna are periodically negatively impacted by the flow of deep waters with very low oxygen concentrations (hypoxic events), and upwelling of corrosive, acidified waters onto the continental shelf. This area is also adjacent to the Cascadia Subduction Zone, which is characterized by episodic seismic tremors. The seafloor junction boxes contain geophysical and near seafloor water column instrumentation, and are attached to an electro-optical cable that provides significant power and 1 Gb two-way communications bandwidth. This seafloor site is also co-located with a Deep and Shallow Profiler Mooring, which collect complementary water column data. When coupled with other Cabled Array and Endurance Array installations off the central Oregon coast, the Slope Base infrastructure allows for measurements of a variety of coastal phenomena, including cross-shelf and along-shelf variability.
