Oceans of Tomorrow sensor interoperability for in-situ ocean monitoring
The Oceans of Tomorrow (OoT) projects,
funded by the European Commission’s FP7 program, are
developing a new generation of sensors supporting physical,
biogeochemical and biological oceanographic monitoring.
The sensors range from acoustic to optical fluorometers to
labs on a chip. The result is that the outputs are diverse in a
variety of formats and communication methodologies. The
interfaces with platforms such as floats, gliders and cable
observatories are each different. Thus, sensorPeer ReviewedPostprint (author's final draft
Applying OGC sensor web enablement to ocean observing systems
The complexity of marine installations
for ocean observing systems has grown significantly in
recent years. In a network consisting of tens, hundreds
or thousands of marine instruments, manual
configuration and integration becomes very
challenging. Simplifying the integration process in
existing or newly established observing systems would
benefit system operators and is important for the
broader application of different sensors. This article
presents an approach for the automatic configuration
and integration of sensors into an interoperable
Sensor Web infrastructure. First, the sensor
communication model, based on OGC's SensorML
standard, is utilized. It serves as a generic driver
mechanism since it enables the declarative and
detailed description of a sensor's protocol. Finally, we
present a data acquisition architecture based on the
OGC PUCK protocol that enables storage and
retrieval of the SensorML document from the sensor
itself, and automatic integration of sensors into an
interoperable Sensor Web infrastructure. Our
approach adopts Efficient XML Interchange (EXI) as
alternative serialization form of XML or JSON. It
solves the bandwidth problem of XML and JSON.Peer ReviewedPostprint (author's final draft
Geo-processing in cyberinfrastructure: making the web an easy to use geospatial computational platform
International audienceAccess to data on the web has become routine based upon open standards from IETF and W3C. Access to explicitly geospatial data is routinely done using data access standards from the OGC. Geoprocessing services on the web are now being developed. Processing of data must be done to apply or fuse the data to meet specific applications. Standards and implementations for processing of data on the web are just now becoming established. For geospatial data, the OGC has defined the Web Processing Service (WPS) interface standard. Now is a critical time to bring convergence to WPS profiles that make the web an easy to use geospatial computational service. Access to network accessible processing services is bringing geoprocessing to the cyberinfrastructure
Report of the workshop on the Implementation of Multidisciplinary Sustained Ocean Observations (IMSOO)
To date, largely independent observing systems have evolved to meet the needs of particular disciplines and end users – many of these still measure only ocean physical variables routinely. The Implementation of Multidisciplinary Sustained Ocean Observations (IMSOO) workshop was held to identify priority steps to further multi-disciplinary collaborations in coordinating continuous and long-term ocean observations for the benefit of better understanding of the ocean and its ecosystems, as well as human impacts and vulnerabilities. The workshop was designed to follow the approach of the Framework for Ocean Observing (FOO), within which societal and scientific requirements for measurements as well as the feasibility of making such measurements combine to prioritize Essential Ocean Variables (EOVs). With the goal of supporting the global implementation of the FOO, an international and multi-disciplinary group of experts in ocean observations and modelling successfully addressed the three major aims of the workshop which were:
To build on the established societal and scientific requirements expressed in EOVs and identify the key applications and phenomena that will benefit from co-located multi-disciplinary sustained observations;
To identify near-term innovation priorities for observing platforms and sensors to enable multi-disciplinary observations; and
To identify programmatic and professional connections between existing and emerging observing networks and modelling efforts that will increase multidisciplinary observations and analyses. To provide an innovative mechanism fostering convergence across the ocean disciplines, the workshop focused on three “demonstration themes”, chosen because they represent global and challenging problems that are best addressed through collaboration of physical, biogeochemical and biological observations and analyses
The Brokering Approach for Multidisciplinary Interoperability: A Position Paper
Global sustainability research requires an integrated multi-disciplinary effort underpinned by a cyber infrastructure able to harness big data and heterogeneous information systems across disciplines. Two approaches are possible to achieve the interoperability desired across such systems and data: federating, and brokering. This position paper argues that the former is appropriate to single discipline or domain environments, but that brokering is more scalable and effective in complex multi-disciplinary domains. The paper identifies the principles of brokering, and gives examples of practical implementation relating to data discovery, semantic searching, and data access achieved in the EuroGEOSS project. The value of the EuroGEOSS brokering approach has been demonstrated in extending the data resources available through the Global Earth Observation System of Systems (GEOSS) from a few hundred to over 28 million in a matter of 3 months. Brokering offers therefore a real chance to facilitate truly multi-disciplinary big data science and address the scientific challenges of our time
Towards a Best Practice for Developing Best Practices in Ocean Observation (BP4BP): Supporting Methodological Evolution through Actionable Documentation
IOC Manuals and Guides, 84
Abstract
Ever-increasing complexity and multi-dimensionality of ocean investigations present a
challenge for the ocean community as we collaboratively (co-)develop methods to research,
monitor, and use our oceans. To support transparent sharing of methods, and ultimately agree
on best practices in ocean research, operations, and application, the IOC Ocean Best
Practices System (OBPS) was initially developed as an Ocean Data Standards project
deliverable of the International Oceanographic Data Exchange (IODE) who in 2017 joined with
the AtlantOS/ODIP/RCN Best Practices Working Group (BPWG) to develop it into a System.
In 2019 the IOC Ocean Best Practices System was approved as a
UNESCO/Intergovernmental Oceanographic Commission (IOC) Project, jointly funded by the
IODE and GOOS Programmes. In this document, we provide guidance on how to best use the
OBPS templates, allowing greater discovery, machine readability, sharing, and
understandability of methods and best practices. We clarify how to optimally populate the
different sections of an OBPS template, and describe how those sections support the evolution
of each OBPS submission, towards a global best practice. Further, we discuss some general
challenges in developing methods into community-accepted best practices. While this
document focuses on the OBPS, it also offers a perspective on the general challenge of
structuring and harmonising method documentation. We invite the community to provide
feedback on this document (link to Community review), to contribute towards a generalised
best practice for advanced methodological management across the ocean community
Facilitating open exchange of data and information

The definitive version was published in Earth Science Informatics 8 (2015): 721-739, doi:10.1007/s12145-014-0202-2.By broad consensus, Open Data presents great value. However, beyond that simple statement, there
are a number of complex, and sometimes contentious, issues that the science community must
address. In this review, we examine the current state of the core issues of Open Data with the
unique perspective and use cases of the ocean science community: interoperability; discovery and
access; quality and fitness for purpose; and sustainability. The topics of Governance and Data
Publication are also examined in detail. Each of the areas covered are, by themselves, complex and
the approaches to the issues under consideration are often at odds with each other. Any comprehensive
policy on Open Data will require compromises that are best resolved by broad community input. In
the final section of the review, we provide recommendations that serve as a starting point for these
discussions.The

Relating Best Practices to Standardization in Ocean Science
Over the past decade, the Ocean Best Practices System, hosted and maintained by the International Oceanographic Data and Information Exchange of UNESCO's Intergovernmental Oceanographic Commission, has grown to become a trusted and stable repository for all types of ocean Best Practices documentation. Given the nature of the information it contains, the repository embodies a unique resource base for supporting initiatives aimed at strengthening standardization in Ocean Science. Based on this consideration, the Ocean Best Practices System is forming a new task team to explore and evaluate the potential role that the comprehensive Best Practice information it secures could play in identifying and prioritizing processes for furthering this objective. Particular care is being taken to keep the work open and transparent through constant community engagement and by linking with international bodies/organizations dealing with measurement
