Session OD11A: Ocean Observatory Science: Unprecedented Access to the Sea I; 8:00-10:00 AM – Room: RO1

8:00-8:15 AM Transforming Ocean Sciences in the Northeast Pacific: NSF’s Ocean Observatories Initiative Cabled Array is Now Operational.
Author: Deborah Kelley
Institution: University of Washington
Abstract OD11A-01: In July-August, 2015 the first operations and maintenance cruise was successfully completed for the high power and bandwidth underwater cabled component of the National Science Foundation’s Ocean Observatories Initiative: the Cabled Array. This system includes 900 km of backbone cable and 7 Primary Nodes, which provide 8 kW power and 10 Gbs bandwidth to myriad seafloor instruments (Manalang et al.,this meeting) and instrumented full water column moorings (McRae et al., this meeting). Over 33,000 m of extension cables connected to 17 secondary junction boxes support >100 instruments now streaming data live to shore. In concert, this array forms: 1) the most advanced observatory along the global mid-ocean ridge network were 20 instruments and a state-of-the-art mooring system are providing new insights into volcanic and overlying water column processes at Axial Seamount (which erupted April 2015, see Delaney et al., this meeting); and 2) an extensive, technologically-advanced coastal observatory spanning 80 m to 2900 m water depths off Newport, OR. Here, cabled, instrumented moorings, with up to 18 instruments each, and associated seafloor arrays provide real-time, coregistered geophysical, biogeochemical, and physical measurements at unprecedented temporal and spatial resolution. Nearly 1.5 years of continuous data (see Knuth et al., this meeting), two-way communication capabilities that allow responses to events, and continuing real-time data flow, will allow the community to investigate in ways never before possible earthquakes along the Cascadia margin with impacts on fluid flow and release of methane into the hydrosphere, underwater eruptions resulting in perturbations to hydrothermal systems, associated biological communities, and overlying water column properties, and linkages among biogeochemical and physical processes along the Cascadia margin.

8:15-8:30 AM The Ocean Observatories Initiative: Data, Data and More Data

Institution: Rutgers University
Abstract OD11A-02: The Ocean Observatories Initiative (OOI), a project funded by the National Science Foundation (NSF) and managed by the Consortium for Ocean Leadership, is a networked infrastructure of science-driven sensor systems that measure the physical, chemical, geological, and biological variables in the ocean and seafloor on coastal, regional, and global scales. OOI long term research arrays have been installed off the Washington coast (Cabled), Massachusetts and Oregon coasts (Coastal) and off Alaska, Greenland, Chile and Argentina (Global). Woods Hole Oceanographic Institution and Oregon State University are responsible for the coastal and global moorings and their autonomous vehicles. The University of Washington is responsible for cabled seafloor systems and moorings. Rutgers University operates the Cyberinfrastructure (CI) portion of the OOI, which acquires, processes and distributes data to the scientists, researchers, educators and the public. It also provides observatory mission command and control, data assessment and distribution, and long-term data management. This talk will present an overview of the OOI infrastructure and its three primary websites which include: 1) An OOI overview website offering technical information on the infrastructure ranging from instruments to science goals, news, deployment updates, and information on the proposal process, 2) The Education and Public Engagement website where students can view and analyze exactly the same data that scientists have access to at exactly the same time, but with simple visualization tools and compartmentalized lessons that lead them through complex science questions, and 3) The primary data access website and machine to machine interface where anyone can plot or download data from the over 700 instruments within the OOI Network.

8:30-8:45 AM A First: Detailed Tracking of an Erupting Undersea Volcano and its Impacts on the Overlying Ocean via a Submarine Electro-Optical Sensor Network.
Author: John Delaney
Institution: University of Washington
Abstract OD11A-03: The scientifically diverse and technologically advanced cabled array component of the NSF’s Ocean Observatories Initiative consists of 900 km of electro-optical fiber deployed from Pacific City, OR, across active portions of the Juan de Fuca (JdF) tectonic plate, and upward into the overlying ocean. This array, completed in 2014 on time and under budget, enables real-time, high-bandwidth, 2-way communication with seafloor and water column sensor arrays across: 1. the Cascadia accretionary prism, 2. the JdF spreading center, and, 3. portions of the overlying NE Pacific. Oceanographic processes in coastal waters, the California Current, and up to 400 km offshore, are captured by six remote-controlled, profiling moorings covering full-ocean depths. Currently, 6 primary nodes, 17 junction boxes, and ~85% of 150 instruments are transmitting data ashore to the Internet via the Pacific NW Gigapop (http://www.pnwgp.net/). All data are archived at the U. of Washington, pending completion of the OOI CyberInfrastructure in October 2015.
In 2014, community requests to access data to assess inflation at Axial Seamount, resulted in NSF releasing real-time data from 7 seismometers and 3 pressure sensors (IRIS: http://www.iris.edu/hq/). On April 20-22, 90 participants, met in Seattle to explore scientific responses to an eruption (http://novae.ocean.washington.edu). On April 24, Axial did erupt; seismic events rose dramatically to many hundreds/hour the Axial caldera floor dropped 2.4 m in ~16 hours and water temperatures rose by ~0.7°C, then declined in 3 weeks to normal values. Water-borne acoustic signals indicated seafloor activity along the rift zone north of Axial. Water column observations also indicated that a large plume of hydrothermal fluid was released during the eruptions. Follow-on field programs documented a 127 m thick lava flow on the northern rift, and a thin eruption within the caldera. These events signal a new era in Ocean Sciences as instantaneous Internet access to events far offshore begin allowing interactive responses to complex processes unfolding within our ocean. The attached figure shows the contact between 3.5 month old lava (black) and a much older flow.

9:00-9:15 AM The Ocean Observatories Initiative Data Management and QA/QC: Lessons Learned and the Path Ahead
Authors: Michael Vardaro, Leila Belabbassi, Lori Garzio, Friedrich Knuth, Michael Smith, Michael Crowley
Institution: Rutgers University
Abstract OD11A-05: The Ocean Observatories Initiative (OOI) is a multi-decadal, NSF-funded program that will provide long-term, near real-time cabled and telemetered measurements of climate variability, ocean circulation, ecosystem dynamics, air-sea exchange, seafloor processes, and plate-scale geodynamics. The OOI platforms consist of seafloor sensors, fixed moorings, and mobile assets containing over 700 operational instruments in the Atlantic and Pacific oceans. Rutgers University operates the Cyberinfrastructure (CI) component of the OOI, which acquires, processes and distributes data to scientists, researchers, educators and the public. It will also provide observatory mission command and control, data assessment and distribution, and long-term data management. The Rutgers Data Management Team consists of a data manager and four data evaluators, who are tasked with ensuring data completeness and quality, as well as interaction with OOI users to facilitate data delivery and utility. Here we will discuss the procedures developed to guide the data team workflow, the automated QC algorithms and human-in-the-loop (HITL) annotations that are used to flag suspect data (whether due to instrument failures, biofouling, or unanticipated events), system alerts and alarms, long-term data storage and CF (Climate and Forecast) standard compliance, and the lessons learned during construction and the first several months of OOI operations.

Abstract IS14A-2291: The Cabled Array portion of the National Science Foundation funded Ocean Observatories Initiative is a large scale, high bandwidth and high power subsea science network designed by the University of Washington Applied Physics Laboratory. Part of that system is a set of winched profilers which continuously scan the upper 200m of the ocean at their deployment sites.
The custom built profilers leverage the Cabled Array’s technology for interfacing collections of science instruments and add the ability to run predefined missions and to switch missions or mission parameters on the fly via command from shore. The profilers were designed to operate continuously for up to two years after deployment after which certain wearing components must be replaced.
The data from the profiler’s science and engineering sensors are streamed to shore via the seafloor network in real time. Data channel capacity from the profilers exceeds 40 Mbps. For profiler safety, mission execution is controlled within the platform. Inputs such as 3D gyro, pressure depth and deployed cable calculations are monitored to assure safe operation during any sea state. The profilers never surface but are designed to approach within 5m of the surface if conditions allow. Substantial engineering effort was focused on reliable cable handling under all ocean conditions.
The profilers are currently operated from subsea moorings which also contain sets of fixed science and engineering sensors. The profilers and their associated mooring instrument assemblies are designed for rapid replacement using ROVs.
We have operated this system for two years, including one annual maintenance turn and information relative to that experience will be included in the paper.

Poster #2394 The Ocean Observatories Initiative: Data Access and Visualization via the Graphical User Interface
Authors: Lori Garzio, Leila Belabbassi, Friedrich Knuth, Michael Smith, Michael Crowley, Michael Vardaro
Institution: Rutgers University
Abstract OD14A-2394: The Ocean Observatories Initiative (OOI), funded by the National Science Foundation, is a broad-scale, multidisciplinary effort to transform oceanographic research by providing users with real-time access to long-term datasets from a variety of deployed physical, chemical, biological, and geological sensors. The global array component of the OOI includes four high latitude sites: Irminger Sea off Greenland, Station Papa in the Gulf of Alaska, Argentine Basin off the coast of Argentina, and Southern Ocean near coordinates 55°S and 90°W. Each site is composed of fixed moorings, hybrid profiler moorings and mobile assets, with a total of approximately 110 instruments at each site. Near real-time (telemetered) and recovered data from these instruments can be visualized and downloaded via the OOI Graphical User Interface. In this Interface, the user can visualize scientific parameters via six different plotting functions with options to specify time ranges and apply various QA/QC tests. Data streams from all instruments can also be downloaded in different formats (CSV, JSON, and NetCDF) for further data processing, visualization, and comparison to supplementary datasets. In addition, users can view alerts and alarms in the system, access relevant metadata and deployment information for specific instruments, and find infrastructure specifics for each array including location, sampling strategies, deployment schedules, and technical drawings. These datasets from the OOI provide an unprecedented opportunity to transform oceanographic research and education, and will be readily accessible to the general public via the OOI’s Graphical User Interface.

Poster #2395 Quality Assurance of Real-Time Oceanographic Data from the Cabled Array of the Ocean Observatories Initiative.
Authors: Orest Kawka, Julie Nelson, Deborah Kelley
Institution: University of Washington, Grays Harbor College
Abstract OD14A-2395: The Cabled Array component of the NSF-funded Ocean Observatories Initiative (OOI) provides access to real-time physical, chemical, geological, and biological data from water column and seafloor platforms/instruments at sites spanning the southern half of the Juan de Fuca Plate. The Quality Assurance (QA) program for OOI data is designed to ensure that data products meet OOI science requirements. This overall data QA plan establishes the guidelines for assuring OOI data quality and summarizes Quality Control (QC) protocols and procedures, based on best practices, which can be utilized to ensure the highest quality data across the OOI program. This presentation will highlight, specifically, the QA/QC approach being utilized for the OOI Cabled Array infrastructure and data and will include a summary of both shipboard and shore-based protocols currently in use. Aspects addressed will be pre-deployment instrument testing and calibration checks, post-deployment and pre-recovery field verification of data, and post-recovery “as-found” testing of instruments. Examples of QA/QC data will be presented and specific cases of cabled data will be discussed in the context of quality assessments and adjustment/correction of OOI datasets overall for inherent sensor drift and/or instrument fouling.

Poster #2396 The Ocean Observatories Initiative: Data Acquisition Functions and Its Built-In Automated Python Modules
Authors: Michael Smith, Michael Vardaro, Michael Crowley, Scott Glenn, Oscar Schofield, Leila Belabbassi, Lori Garzio, Friedrich Knuth,Jonathan Fram
Institutions: Rutgers University, Oregon State University
Abstract OD14A-2396: The Ocean Observatories Initiative (OOI), funded by the National Science Foundation, provides users with access to long-term datasets from a variety of oceanographic sensors. The Endurance Array in the Pacific Ocean consists of two separate lines off the coasts of Oregon and Washington. The Oregon line consists of 7 moorings, two cabled benthic experiment packages and 6 underwater gliders. The Washington line comprises 6 moorings and 6 gliders. Each mooring is outfitted with a variety of instrument packages. The raw data from these instruments are sent to shore via satellite communication and in some cases, via fiber optic cable. Raw data is then sent to the cyberinfrastructure (CI) group at Rutgers where it is aggregated, parsed into thousands of different data streams, and integrated into a software package called uFrame. The OOI CI delivers the data to the general public via a web interface that outputs data into commonly used scientific data file formats such as JSON, netCDF, and CSV. The Rutgers data management team has developed a series of command-line Python tools that streamline data acquisition in order to facilitate the QA/QC review process. The first step in the process is querying the uFrame database for a list of all available platforms. From this list, a user can choose a specific platform and automatically download all available datasets from the specified platform. The downloaded dataset is plotted using a generalized Python netcdf plotting routine that utilizes a data visualization toolbox called matplotlib. This routine loads each netCDF file separately and outputs plots by each available parameter. These Python tools have been uploaded to a Github repository that is openly available to help facilitate OOI data access and visualization.

Institutions: Rutgers University and the University of Washington
Abstract OD14A-2397: The National Science Foundation’s Ocean Observatories Initiative (OOI), is a broad-scale, multidisciplinary facility that will transform oceanographic research by providing users with unprecedented access to long-term datasets from a variety of deployed physical, chemical, biological, and geological sensors. The Cabled Array component of the OOI, installed and operated by the University of Washington, is located on the Juan de Fuca tectonic plate off the coast of Oregon. It is a unique network of >100 cabled instruments and instrumented moorings transmitting data to shore in real-time via fiber optic technology. Instruments now installed include HD video and digital still cameras, mass spectrometers, a resistivity-temperature probe inside the orifice of a high-temperature hydrothermal vent, upward-looking ADCP’s, pH and pC02 sensors, Horizontal Electrometer Pressure Inverted Echosounders and many others. Here, we present the technical aspects of data streaming from the Cabled Array through the OOI Cyberinfrastructure. We illustrate the types of instruments and data products available, data volume and density, processing levels and algorithms used, data delivery methods, file formats and access methods through the graphical user interface. Our goal is to facilitate the use and access to these unprecedented, co-registered oceanographic datasets. We encourage researchers to collaborate through the use of these simultaneous, interdisciplinary measurements, in the exploration of short-lived events (tectonic, volcanic, biological, severe storms), as well as long-term trends in ocean systems (circulation patterns, climate change, ocean acidity, ecosystem shifts).

Poster #2399 The Ocean Observatories Initiative: Data pre-Processing: Diagnostic Tools to Prepare Data for QA/QC Processing
Authors: Leila Belabbassi,Lori Garzio, Michael Smith, Friedrich Knuth, Michael Vardaro
Institution: Rutgers University
Abstract OD14A-2399: The Ocean Observatories Initiative (OOI), funded by the National Science Foundation, provides users with access to long-term datasets from a variety of deployed oceanographic sensors. The Pioneer Array in the Atlantic Ocean off the Coast of New England hosts 10 moorings and 6 gliders. Each mooring is outfitted with 6 to 19 different instruments telemetering more than 1000 data streams. These data are available to science users to collaborate on common scientific goals such as water quality monitoring and scale variability measures of continental shelf processes and coastal open ocean exchanges. To serve this purpose, the acquired datasets undergo an iterative multi-step quality assurance and quality control procedure automated to work with all types of data. Data processing involves several stages, including a fundamental pre-processing step when the data are prepared for processing. This takes a considerable amount of processing time and is often not given enough thought in development initiatives. The volume and complexity of OOI data necessitates the development of a systematic diagnostic tool to enable the management of a comprehensive data information system for the OOI arrays. We present two examples to demonstrate the current OOI pre-processing diagnostic tool. First, Data Filtering is used to identify incomplete, incorrect, or irrelevant parts of the data and then replaces, modifies or deletes the coarse data. This provides data consistency with similar datasets in the system. Second, Data Normalization occurs when the database is organized in fields and tables to minimize redundancy and dependency. At the end of this step, the data are stored in one place to reduce the risk of data inconsistency and promote easy and efficient mapping to the database.

Poster #2423 Modular Seafloor and Water Column Systems for the Ocean Observatories Initiative Cabled Array

Abstract OD14B-2423: Over the past decade, cabled ocean observatories have become an increasingly important way to collect continuous real-time data at remote subsea locations. This has led to the development of a class of subsea systems designed and built specifically to distribute power and bandwidth among sensing instrumentation on the seafloor and throughout the water column. Such systems are typically powered by shore-based infrastructure and involve networks of fiber optic and electrical cabling that provide real-time data access and control of remotely deployed instrumentation. Several subsea node types were developed and/or adapted for cabled use in order to complete the installation of the largest North American scientific cabled observatory in Oct, 2014. The Ocean Observatories Initiative (OOI) Cabled Array, funded by the US National Science Foundation, consists of a core infrastructure that includes 900 km of fiber optic/electrical cables, five primary nodes, 18 seafloor junction boxes, three mooring-mounted winched profiling systems, and three wire-crawling profiler systems. In aggregate, the installed infrastructure has 200 dedicated scientific instrument ports (of which 120 are currently assigned), and is capable of further expansion. The installed system has a 25-year design life for reliable, sustained monitoring; and all nodes, profilers and instrument packages are ROV-serviceable. Now in it’s second year of operation, the systems that comprise the Cabled Array are providing reliable, 24/7 real-time data collection from deployed instrumentation, and offer a modular and scalable class of subsea systems for ocean observing. This presentation will provide an overview of the observatory-class subsystems of the OOI Cabled Array, focusing on the junction boxes, moorings and profilers that power and communicate with deployed instrumentation.

Poster #2455 Operationalizing Surface Piercing Profilers
Authors: Jonathan Fram, Jack Barth, Edward Dever, Bruce Rhoades, John Koegler
Institutions: Oregon State University, Sea-Bird Scientific
Abstract OD24A-2455: High vertical resolution profiles of surface waters with multi-parameter sensor packages are valuable for understanding coupled physical-biogeochemical ocean processes. Typically, these profilers are only able to be used for short periods of time due to lack of ruggedness, reliability, automation, and battery life. Over the last three years, the Ocean Observatories Initiative has partnered with WET Labs to improve a set of WET Labs Thetis profilers so that OOI can operate six of them year-round in waters up to 100 m in depth. These profiles sample 1-16 Hz while rising 25 cm/s. They include 8 instruments with more than a dozen sensors, and they have room for more. A smart winch on-board these profilers compensates for wave-driven heave, which enables them to surface and telemeter data via Iridium in up to 3 m waves, 10 m/s winds, and 40 cm/s mean water currents. Multiple firmware and electronics upgrades enable these profilers to automatically recover from problems, or at least put themselves in a state that minimizes the chance of loss/damage and allows for remote query & control via acoustic modem from a neighboring surface mooring. These and other improvements enable the system to capture periods of the year such as the beginning of the annual coastal upwelling-dominated period without fear from damage by spring storms. This contribution will show the new features, the overall capabilities, and the limitations of these profilers, and it will show what data are available from them through OOI.

Poster #1728 The OOI Ocean Education Portal: Enabling the Development of Online Data Investigations
Authors: Charles Lichtenwalner, Janice McDonnell, Michael Crowley, Annette deCharon, Carla Companion. Scott Glenn
Institutions: Rutgers University, University of Maine
Abstract ED44B-1728: The Ocean Observatories Initiative (OOI) was designed to transform ocean science, by establishing a long-term, multi-instrument, multi-platform research infrastructure at 7 arrays around the word. This unprecedented investment in ocean observation, funded by the National Science Foundation, provides a rich opportunity to reshape ocean science education as well. As part of the initial construction effort, an online Ocean Education Portal was developed to support the creation and sharing of educational resources by undergraduate faculty at universities and community colleges. The portal includes a suite of tools that enable the development of online activities for use as group or individual projects, which can be used during lectures or as homework assignments. The site includes: 1) a suite of interactive educational data visualization tools that provide simple and targeted interfaces to interact with OOI datasets; 2) a concept map builder that can be used by both educators and students to build networked diagrams of their knowledge; and 3) a “data investigation” builder that allows faculty to assemble resources into coherent learning modules. The site also includes a “vocabulary navigator” that provides a visual way to discover and learn about the OOI’s infrastructure and scientific design. The site allows users to browse an ever-growing database of resources created by the community, and likewise, users can share resources they create with others. As the OOI begins its 25-year operational phase, it is our hope that faculty will be able to use the tools and investigations on the Ocean Education Portal to bring real ocean science research to their undergraduate students.
