On 11 October 2021, the National Oceanic and Atmospheric Administration (NOAA)requested that OOI’s Coastal Endurance Array buoys provide hourly meteorological data to the National Data Buoy Center (NDBC) because a nearby NDBC buoy (46029, Columbia River bar) had gone offline. OOI buoy data are typically telemetered every two hours due to sampling schedule and bandwidth constraints (the actual sampling rate is higher).
Endurance Array team members examined sampling and telemetry schedules for the Endurance offshore coastal surface moorings to see if they could accommodate NOAA’s request. The team concluded that meteorological data from the moorings could be updated hourly while still meeting OOI sampling requirements.
“To help ensure continuity of data to the NDBC, we plan to distribute hourly meteorological data from the Endurance Array Oregon and Washington offshore sites for the duration of the outage at NBDC 46029,” said Edward Dever, lead of the Coastal Endurance Team. “We’re pleased to respond to NOAA’s request and hope these data prove useful to operational weather forecasts and marine safety.” The Oregon and Washington offshore sites have NDBC buoys designations of 46098 and 46100, respectively.
The Endurance Array team will continue to review the performance of the buoys and ensure the updated telemetry schedule does not impact OOI sampling. If data users do experience any impacts from this change in sampling frequency, please contact Jon Fram at Jonathan.Fram@oregonstate.edu.Read More
In September 2021, the Coastal Endurance Array began rolling out a much-needed upgrade to their underwater cameras. Endurance Array Innovator Chris Holm engineered a camera using off-the-shelf components to meet the specific needs of capturing environmental conditions and marine life in proximity to the Endurance Array moorings. The prototype was put in place on the inshore mooring (CE01) during the 15th turn of the Coastal Endurance Array.[media-caption path="https://oceanobservatories.org/wp-content/uploads/2021/10/camera.png" link="#"]The newly configured Endurance Array underwater camera is attached to the inshore mooring, ready for deployment.

The innovation came in multiple steps. Holm first tried to salvage the camera’s hardware and reprogram the camera with new software. He hit a snag, however, in that the motherboard that controlled the camera was no longer supported.
Since it didn’t make sense to rebuild the camera using an out-of-date motherboard, Holm looked into finding a new camera on the market. It had to be suitable for use underwater, with the capability to go into a low-power mode. “What is really needed for low-light conditions underwater is a camera with a large physical sensor, but with fewer megapixels,” explained Holm.
“Since the moorings run on battery power, the cameras need to be able to go into a very low-power sleep state in between taking photos,” said Holm. “If the sleep current is high, the deployment life is low. So, we were trying to find an off-the-shelf solution for a way to go into low power.”
After some searching, Holm obtained a Raspberry Pi High Quality Camera. Although the Raspberry Pi doesn’t come with native power management capabilities, Holm found he could use Sleepy Pi, an add-on-board from Spell Foundry that can power the Raspberry Pi on and off.
For its launch, the camera is programmed to autonomously take a burst of three images every four hours. The system can also take photos when triggered by a Data Concentration Logger (DCL) and can be partially configured remotely. Future iterations will be fully configurable remotely via the DCL.
The final touch to this first iteration was figuring out how to turn the lights and lasers on and off. Holm used a relay board from Waveshare Electronics to power the original systems lights and lasers. The lights adjust their brightness depending on the voltage being sent through a signal line which is controlled by the GPIO pins of the Raspberry Pi.
Altogether, the system is very suitable for the Endurance Array’s needs and is an extremely cost-effective, off-the-shelf solution. The cameras also can be easily swapped out if the Endurance team decides to upgrade the cameras.
Since this newly configured camera was put in place in early September, Holm said, it has been performing flawlessly, with the auto-exposure working well. Since this mooring uses a cell modem to transmit data, the team has been able to see the photos the camera is taking in near real-time. Once the formal approval process for the camera’s integration and use across the OOI is completed, Holm will be building more camera systems for the Endurance Array to deploy on the offshore and shelf moorings during the spring.
Since the cameras and its settings can be upgraded and/or optimized for different use cases, depending on what an investigator is interested in (such as marine snow or benthic organisms), Holm would like to hear from scientists about what they’d like the camera to focus on. He created a survey for data users interested in the underwater cameras.
“It would be very helpful to know what kind of data would be most useful to scientists using the system,” he said.

In spite of rocking seas, a generator in need of repair, and a medical delay, the Coastal Endurance Array team successfully completed its mission to turn the array for the 15th time, achieving all of its science objectives.
Weather conditions in the northern Pacific were less-than-ideal for two of the three legs of the two-week expedition. At one point, winds speeds of 25-30 knots, with accompanying waves of up to 10 feet, caused a weather delay in operations and subsequent alterations in cruise plans.
“While it was comfortable to be aboard the R/V Thomas G. Thompson even in such conditions, sea conditions were borderline for entering or exiting Newport and deploying or recovering most platforms, “explained Chief Scientist Jonathan Fram, who led the 10-member science party. “Fortunately, we had good weather during the first leg of the cruise, which gave us some leeway to address weather-related downtime and other delays during latter legs of the cruise. We were able to switch the order of some activities, delay some deployments, and ultimately got most everything in and out of the water as planned during our time at sea.”[media-caption path=”https://oceanobservatories.org/wp-content/uploads/2021/09/Screen-Shot-2021-09-28-at-5.20.52-PM.png” link=”#”]When seas were calm, the team was able to deploy moorings like this one. After deployment, they headed back to port with a deck full of recovered equipment.[/media-caption]
The team successfully deployed and recovered six surface moorings, four gliders, and two profilers. They also recovered two additional profilers and an anchor from 2020. In addition, the team conducted CTD water sampling and also conducted sampling for researchers with instruments on Endurance Array moorings. The team succeeded in collecting fouling communities growing on buoy panels for researcher Linsey Haram of the Smithsonian Institution and organisms on devices attached to two multi-function nodes for Oklahoma State researcher Ashley Burkett.
While in the roaring sea, the team tested potential instrument replacements and new sampling strategies. They also assessed first-time implementation of technical improvements including a new solar panel frame to prevent sea lions from unplugging the panels, an underwater camera constructed with off-the-shelf replacement parts to ensure longevity and resilience, and a stretch hose from a new manufacturer with a slightly different design than previous versions.
“In spite of having to repeatedly change our plans,” adds Fram, “we were pleased to be able to meet all of the cruise objectives. The ocean in the Pacific Northwest is too harsh for scientists to go to sea often in fall and winter, so it is important to refresh this array of autonomous platforms that will keep recording and delivering data during rough times.”Read More
On September 8th, a science team of ten and three students from Oregon State University will depart the dock at Newport, Oregon, aboard the R/V Thomas Thompson for the 15th turn of the Coastal Endurance Array. The team will recover and deploy seven moorings. Four of the moorings are located on the Washington Shelf, with the remaining three on the Oregon Shelf. It’s a busy expedition. The team also will be recovering four and deploying three Coastal Surface Profilers and recovering three gliders that are low on power. When not turning the arrays, they will be taking CTD (connectivity, temperature, and depth) casts to verify and calibrate instrumentation. Because of the quantity of the equipment to be recovered and deployed, the cruise will consist of three legs.
“As we head to sea for the fifteenth time to turn this array, it’s remarkable to consider that the Endurance Array has been generating data for researchers, teachers, and others interested in the ocean, every day, 24/7 for the past seven years, said Jonathan Fram, who is the chief scientist for Endurance 15. “Our data has helped identify everything from warm blobs to low-oxygen events, to even the impact of forest fire smoke miles from shore.”[media-caption path=”https://oceanobservatories.org/wp-content/uploads/2021/09/Screen-Shot-2021-09-03-at-3.17.24-PM.png” link=”#”]Members of the Coastal Endurance Array 15 team prepare moorings for moving to pier for loading onto the R/V Thomas Thompson.

To help advance science, the Endurance 15 team also will be sampling for researchers with instruments on the Endurance Array moorings. The team will collect fouling communities growing on panels attached to its deployed buoys for researcher Linsey Haram of the Smithsonian Institution. They will also collect settling organisms on devices attached to two multi-function nodes for Oklahoma State researcher Ashley Burkett.
The team also will be testing potential instrument replacements and new sampling strategies for coastal moorings. Additionally, they will be assessing technical improvements to the moorings and instrumentation that range from a new solar panel frame design to prevent sea lions from unplugging the panels to improvements to cameras deployed on the moorings with off-the-shelf replacement parts to ensure longevity and resilience.

In its August 2021 newsletter, Oregon Sea Grant highlights the work of OOI’s Endurance Array Team at Oregon State University. Sea Grant Scholar Charlotte Klein interviewed the Endurance Array Principal Investigator Ed Dever, who describes some of challenges in keeping arrays operational in a challenging offshore environment.

OOI uses the SAMI2-pH sensor from Sunburst Sensors, LLC to measure seawater pH throughout the different arrays. Assessing the data quality from this instrument is an involved process as there are multiple parameters produced by the instrument that are then used to calculate the seawater pH. These measurements are subject to different sources of error, and those errors can propagate through the calculations to create an erroneous seawater pH value. Based upon the vendor documentation and MATLAB code Sunburst provides to convert the raw measurements, OOI data team members have created a set of rules from those different measurements to flag the pH data as either pass, suspect or fail.
The resulting flags can be used to remove failed data from further analysis. They can also be used to help generate annotations for further Human in the Loop (HITL) QC checks of the data to help refine quality metrics for the data. OOI team member, Chris Wingard (OSU), has written up the QC process as a Python Jupyter notebook. This notebook and other example notebooks are freely available to the scientific community via the OOI GitHub site (within the OOI Data Team Python toolbox accessed from https://oceanobservatories.org/community-tools/ ).
In this notebook, Wingard shows how the quality rules can be used to remove bad pH data from a time series, and how they can be used to then create annotations. The impact of using these flags is shown with a set of before and after plots of the seawater pH as a function of temperature. The quality controlled data can then be used to estimate the seasonal cycle of pH to set climatological quality control flags.
Here an example is shown using data from a pH sensor on the Oregon Inshore Surface Mooring (CE01ISSM) near surface instrument frame (NSIF), deployed at 7 m depth (site depth is 25 m).[media-caption path="https://oceanobservatories.org/wp-content/uploads/2021/07/EA-Highlight.png" link="#"]Figure 25: pH data from the Oregon Inshore Surface Mooring (CE01ISSM) near surface instrument frame (NSIF). Good data are shown in black, failed data in red. Note that simple range tests on the final calculated pH are often not enough to distinguish good from failed data. The automated QC processing examines intermediate measurements and fails data if intermediate measurements are outside acceptable ranges and propagated to final measurements.[/media-caption] [media-caption path="https://oceanobservatories.org/wp-content/uploads/2021/07/EA-highlight-2.png" link="#"]Figure 26: Good data together with annual cycles (red) constructed with available good data from initial deployment through 2021.

From 21-25 June, 37 members of the Ocean Observatories Initiative (OOI) community are participating in the National Science Foundation-sponsored Phase 2 Innovations Lab to identify the best location within the recently designated geographic region of the Mid-Atlantic Bight (MAB) between Cape Hatteras and Norfolk Canyon for the Pioneer Array relocation.
During the week, participants will work to identify the observatory opportunities that can be offered by the new Pioneer Array location. They will explore how the Pioneer Array sensors and platforms can be optimized to achieve science and education goals at a new site, based on environmental, logistical, and infrastructural considerations. The group will also evaluate challenges presented by deployment of Array infrastructure at a new location, and discuss the potential for partnerships and collaborations at a new site.
The MAB region offers opportunities to collect data on a wide variety of cross-disciplinary science topics including cross-shelf exchange, land-sea interactions associated with large estuarine systems, a highly productive ecosystem with major fisheries, and carbon cycle processes. This geographic region also offers opportunities to improve understanding of hurricane development, tracking and prediction, and offshore wind partnerships. The relocation of the Pioneer Array will take place in 2024.
The Ocean Observatories Initiative Facilities Board (OOIFB), in partnership with KnowInnovations, is facilitating the Phase 2 Innovations Lab. “We selected a diverse mix of Lab participants to achieve a broad range of disciplines and professional expertise, career stage (from early to senior), gender, cultural background, and life experience. By involving such a wide range of people in the conversations this week, it is our hope that the innovative quality, outputs, and outcomes of the Lab will be enriched,” said Kendra Daly, chair of the OOIFB. “And, throughout the year, we will continue to work with the community on the exciting optimization process via scientific meetings, seminars, and other means to ensure we receive broad input.”Read More
The sea surface is the hardest place to work, according to Jonathan Fram, Project Manager of the Coastal Endurance Array. That’s because at the surface, waves are constantly sloshing around. At any time, a large wave can tug on mooring winch lines, creating sudden tension, which can wear down cables and even cause them to break.
Scuba divers know that surface waters are rough, but below a certain depth—about one wave orbital below the surface—the waters calm significantly. Unfortunately, a lot of great science takes place at the surface, so it’s important for sampling instruments like the Coastal Surface Piercing Profiler (CSPP) to be able to withstand the waves at and near the surface. Fortunately, OOI engineers have found ways to meet the many challenges of working in this rough environment.
“The Coastal Endurance Array Team has made changes to the CSPP to make it more robust, so that we can get the kind of continuous time series that are so valuable to scientists,” said Fram.
A CSPP spends most of its time near the sea floor, but either two or four times a day, the profiler winches itself up to the surface, taking samples as it ascends. Once it reaches the surface, the profiler sends its data back to shore and then quickly returns to the safety of the seafloor. Profilers are important ocean observatory tools because they can help capture what is happening at certain depths where stationary instruments aren’t present. “We’ve had times where you get a persistent chlorophyll bloom at a certain depth where there is zero mooring data,” explained Fram. “So the CSPP sampling is needed to make sense of what’s happening. It’s impossible to have all the instruments at all depths. The CSPP fills in this gap.”
Last year, the Coastal Endurance Array team reviewed their activities looking for ways to reduce lost time at sea. One thing they discovered was that the anchor systems of the CSPPs were unreliable. To deal with this problem, the team created a new kind of anchor. The old profiler anchors had a chain between the profiler and anchor that helped dampen the waves so that the device was not tugged on when resting in between profiles. The chain, however, made it difficult to deploy the anchor in an upright position. Anchors need to be deployed upright so their recovery floats can be acoustically released. The team redesigned the anchors so they now behave like a weeble wobble toy that is weighted so it always rights itself. This new design makes it hard to deploy an anchor upside down, making the anchors more reliable.
The team also made updates to the modems that send data to shore. When the CSPP is at the surface, the winch must stay on because it keeps the antenna vertical. This time-on takes up about a quarter of the battery power. To reduce the power demand, the team switched out some of the iridium modems for cellular modems, which has allowed the CSPPs to send data more quickly. A faster modem means that the profiler spends less time at the surface, not only saving power, but reducing the risk of being damaged by a large wave. The team is currently working on upgrading to faster cellular modems that can connect further from shore.
“At the same time we are making these updates on the Oregon Shelf Mooring, we’re also implementing them on the Washington Shelf Mooring,” said Fram. “So an improvement on one platform is also leading to an improvement on another platform.”
A third innovation involves improvements to the batteries.
“When waves tug on the winch, it goes from being a power sink to a power source. That sometimes creates power spikes that can fry the connectors. So we’ve rewired the batteries to make them more robust,” explained Fram. The rewiring is expected to reduce the number of power failures and keep the CSPPs running continuously. “Since April when we first started using the rewiring scheme, we’ve had four profilers in the water with no problems for six weeks,” said Fram.
The team also is in the process of replacing batteries that power the profiler with their own design of rechargeable batteries. While OOI engineers prefer to use commercially available parts for easier repair and replacement, when parts on the market don’t fit their needs, they design their own. The new batteries will be more reliable than those they are replacing. The newly designed batteries will also be deployed on the wire-following profilers on the Coastal Pioneer Array.
“My focus is on making all of the Coastal Endurance instrumentation work,” said Fram. “When we’re able to get a full three months’ deployment through the winter, through super rough seas, that makes my day. Making improvements is what I look forward to the most.”Read More
The OOI’s Coastal and Global Array teams regularly use Teledyne-Webb Slocum Gliders to collect ocean observations within and around the array moorings. The gliders fly up and down the water column from the surface down to a maximum depth of 1000 meters, collecting data such as dissolved oxygen concentrations, temperature, salinity, and other physical parameters to measure ocean conditions.
OOI shares its glider data with the Integrated Ocean Observing System (IOOS) Glider Data Assembly Center (DAC). IOOS serves as a national repository for glider data sets, serving as a centralized location for wide distribution and use. It allows researchers to access and analyze glider data sets using common tools regardless of the glider type or organization that deployed the glider.
OOI serves data to these repositories in two ways. When the gliders are in the water, data are telemetered, providing near real-time data to these platforms. Once the gliders are recovered, data are downloaded, metadata provided, and data are resubmitted to the Glider DAC as a permanent record.
The behind-the-scene process transmitting this huge amount of data is quite complex. OOI Data Team members, Collin Dobson of the Coastal and Global Scale Nodes at Woods Hole Oceanographic Institution (WHOI) and Stuart Pearce of the Coastal Endurance Array at Oregon State University (OSU) teamed up to streamline the process and catch up on a backlog of submission of recovered data.
Pearce took the lead in getting the OOI data into the DAC. In 2018, he began writing code for a system to transmit near real-time and recovered data. Once the scripts (processing code) were operational by about mid-2019, Pearce implemented them to streamline the flow of Endurance Array glider data into the DAC. Dobson then adopted the code and applied it to the transmission of glider data from the Pioneer, Station Papa, and Irminger Sea Arrays into the repository.
As it turned out, timing was optimum. “ I finished my code at the same time that the Glider DAC allowed higher resolution recovered datasets to be uploaded,” said Pearce. “So I was able to adjust my code to accommodate the upload of any scientific variable as long as it had a CF compliant standard name to go with it.” This opened up a whole range of data that could be transmitted in a consistent fashion to the DAC. CF refers to the “Climate and Forecast” metadata conventions that provide community accepted guidance for metadata variables and sets standards for designating time ranges and locations of data collection. Dobson gave an example of the name convention for density: Sea_water_density.
“Being CF compliant ensures your data have the required metadata and makes the data so much more usable across the board,” added Dobson. “If I wanted to include oxygen as a variable, for example, I have to make sure to use the CF standard name for dissolved oxygen and report the results in CF standard units.”
The Endurance Array team was the first group to add any of the non-CTD variables into the Glider DAC. This important step forward was recognized by the glider community, and was announced at a May 2019 workshop at Rutgers with 150 conveyors of glider data in attendance. One of Pearce’s gliders was used as the example of how and what could be achieved with the new code.
To help expedite the transfer of all gliders into the DAC, Pearce made his code open access. The additional metadata will help advance the work of storm forecasters, researchers, and others interested in improving understanding ocean processes.
OOI shares data with partner repositories and institutions that host similar data but have different user bases. These partnerships expand the data available for forecasting models, help provide insight into current ocean conditions, and serve as important resources for many ranging from fishers and other maritime users to land-based researchers and students.
With the exception of the Station Papa Array, the OOI Coastal and Global Arrays maintain surface buoys. Instruments deployed on these buoys measure meteorological variables such as air temperature, barometric pressure, northward and eastward wind velocities, precipitation, solar radiation, and surface water properties of sea surface temperature and salinity. Other instruments on the moorings collect wave data, such as significant wave height, period, and direction. These data are then consumed by national and regional networks to improve accuracy of weather forecasting models.
The Regional Cabled Array (RCA) consists of fiber-optic cables off the Oregon coast that provide power, bandwidth, and communication to seafloor instrumentation and moorings with instrumented profiling capabilities. A diverse array of geophysical, chemical, and biological sensors, a high-definition camera, and digital still cameras on the seafloor and mooring platforms, provide real-time information on processes operating on and below the seafloor and throughout the water column, including recording of seafloor eruptions, methane plume emissions and climate change. These data are available for community use. Since 2015, the RCA has fed data into Incorporated Research Institutions for Seismology (IRIS), the primary source for data related to earthquakes and other seismic activity. In addition, data including zooplankton sonar data, are being utilized within the Pangeo ecosystem for community visualization and access and pressure data are incorporated into NOAA’s operational tsunami forecasting system.
Helping Improve Models and Forecasting
One of the recipients of OOI data is the National Data Buoy Center (NDBC), part of the National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service. NDBC maintains a data repository and website, offering a range of standardized real-time and near real-time meteorological data. Data such as wind speed and direction, air and surface water temperature, and wave height and direction are made available to the broader oceanographic and meteorological community.
“Many researchers go to NDBC for their data, “said Craig Risien, a research associate with OOI’s Endurance Array and Cyberinfrastructure Teams, who helps researchers gain access to and use OOI data. “NBDC is a huge repository of data and it’s easy to access. So there’s a low barrier for researchers and students who are looking for information about wind speed, water temperature and a slew of other data. OOI contributing to this national repository significantly increases its data reach, allowing OOI data to be used by as many people as possible. “
OOI sea surface temperature data also make their way into the operational Global Real-Time Ocean Forecast System (RTOFS) at the National Centers for Environmental Prediction (NCEP), another part of NOAA’s National Weather Service. RTOFS ingests sea surface temperature and salinity data from all available buoys into the Global Telecommunications System (GTS). OOI glider data also are pushed in near real-time to the US Integrated Ocean Observing System Glider Data Assembly Center (DAC). From there, the data goes to the GTS where it can be used by the operational modeling centers such as NCEP and the European Centre for Medium-Range Weather Forecasts.
The GTS is like a giant vacuum sucking up near real-time observations from all sorts of different platforms deployed all over the world. On a typical day, the GTS ingests more than 7,600 data points from fixed buoys alone. As a result of this vast input, researchers can go to the GTS, pull available data, and assimilate that information into any model to improve its prediction accuracy.
Advancing Forecasting of Submarine Eruptions
As the first U.S. ocean observatory to span a tectonic plate, RCA’s data are an invaluable contributor to IRIS’s collection. Since 2015, the user community has downloaded >20 Terabytes of RCA seismometer data from the IRIS repository. Fourteen different sampling locations include key sites at Axial Seamount on the Juan de Fuca mid-ocean ridge spreading center, near the toe of the Cascadia Margin and Southern Hydrate Ridge. RCA data are catalogued and available on the IRIS site, using the identifier “OO.”[caption id="attachment_21046" align="alignleft" width="300"] Data from short period seismometers installed at RCA’s Axial Seamount and Southern Hydrate Ridge sites are streamed live to IRIS. Credit: UW/NSF-OOI/Canadian Scientific Submersible Facility, V13.[/caption]
“RCA is a critical community resource for seismic data. Axial Seamount, for example, which erupted in 1998, April 2011, was the site of more than 8,000 earthquakes over a 24-hour period April 24, 2015 marking the start of large eruption,” explained Deb Kelley, PI of the RCA. “Being able to witness and measure seismic activity in real time is providing scientists with invaluable insights into eruption process, which along with co-registered pressure measurements is making forecasting possible of when the next eruption may occur. We are pleased to share data from this volcanically and hydrothermally active seamount so researchers the world over can use it to better understand processes happening at mid ocean ridges and advance forecasting capabilities for the first time of when a submarine eruption may occur.”
Providing Data with Regional Implications[caption id="attachment_21047" align="alignright" width="203"] Data from Endurance Array buoy 46100 are fed into WCOFS, where they are accessible to maritime users. Credit: OSU[/caption]
OOI also provides data to regional ocean observing partners. Data from two Endurance Array buoys (46099 and 46100), for example, are fed into a four-dimensional U.S. West Coast Operational Forecast System (WCOFS), which serves the maritime user community. WCOFS generates water level, current, temperature and salinity nowcast and forecast fields four times per day. The Coastal Pioneer Array is within the future Northeastern Coast Operational Forecast System (NECOFS). Once operational, Pioneer’s observations will potentially be used for WCOFS data assimilation scenario experiments.
Coastal Endurance Array data are shared with the Northwest Association of Networked Ocean Observing Systems (NANOOS), which is part of IOOS, and the Global Ocean Acidification Observing Network (GOA-ON). Endurance data are ingested by the NANOOS Visualization System, which provides easy access to observations, forecasts, and data visualizations. Likewise, for GOA-ON, the Endurance Array provides observations useful for measuring ocean acidification.
Data from three of the Pioneer Array buoys also are part of the Mariners’ Dashboard, a new ocean information interface at the Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS). Visitors can use the Dashboard to explore the latest conditions and forecasts from the Pioneer Inshore (44075), Central (44076), and Offshore (44077) mooring platforms, in addition to 30+ other observing platforms throughout the Northeast.
“We are working hard to distribute the OOI data widely through engagement with multiple partners, which together are helping inform science, improve weather and climate forecasts, and increase understanding of the ocean,” added Al Plueddemann, PI of the Coastal and Global Scale Nodes, which include the Pioneer, Station Papa, and Irminger Sea Arrays.
