What is EDMED?

EDMED is a comprehensive reference to the marine datasets and collections held within European research laboratories. It provides marine scientists, engineers and policy makers with a simple mechanism for data discovery.

Its origins date back to 1991 and it has undergone various revisions under the SEA-SEARCH and SeaDataNet initiatives. It has established itself as a European standard for indexing and searching datasets relating to the marine environment.

It covers a wide range of disciplines, for example

marine meteorology and atmospheric chemistry
physical, chemical and biological oceanography
human impact on the environment
fisheries and aquaculture
coastal and estuarine studies
marine geology and geophysics

EDMED catalogues datasets, irrespective of their format. Entries describe

digital databases or files
analogue records — paper charts, hard-copy tabulations
photographs and videos
geological samples
biological specimens

Directory entries are prepared by institutes and collated nationally. These national directories are combined to provide a single centralised system managed by BODC.

New National Oceanography Centre Director appointed.

2010-04-19T17:33:00.001+01:00

The British Oceanographic Data Centre (BODC) wishes to welcome Professor Edward Hill as the new Director of our host laboratory, the NERC's National Oceanography Centre (NOC). He takes up his new role with immediate effect and we are looking forward to working with him.

Professor Edward Hill ©

NOC was formed on 01 April 2010 by bringing together into a single institution the NERC-managed activity at the National Oceanography Centre, Southampton (NOCS) and the Proudman Oceanographic Laboratory (POL) in Liverpool.

Professor Hill, the former director of NOCS, was selected to lead the new centre following an open recruitment and selection process. Professor Andrew Willmott, the former director of POL, will be a key member of the senior leadership team for NOC.

NOC will work in close partnership with the wider marine science community to create the integrated research capability needed to tackle the big environmental issues facing the world. Research priorities will include the oceans' role in climate change, sea level change and the future of the Arctic Ocean.

BODC joins the SeaDataNet Virtual Data System

2010-03-08T11:04:00.002Z

The British Oceanographic Data Centre (BODC), with an initial contribution of more than 10,000 data series, has joined 24 other SeaDataNet partners actively providing data through the SeaDataNet Virtual Data System. The system is based on an index, the Common Data Index (CDI), which is populated with ISO19115-based metadata records to describe data stored in either netCDF or a simple ASCII format.

SeaDataNet partners in Europe ©

The CDI is searchable through a portal interface, which provides a range of filtering options to identify data (profile, time series or trajectory) of interest that may be added to a 'shopping trolley' for subsequent delivery.

Most data in the system are freely available under the terms and conditions of the SeaDataNet licence but some may require negotiation with the data owners before they can be released. User registration, which includes agreeing to the SeaDataNet licence, is mandatory.

The SeaDataNet partnership brings together 49 major European institutes and marine data centres from 35 countries in and around Europe. These include

40 National Oceanographic Data Centres and Satellite Data Centres — representing the backbone of the marine data and information infrastructure
Research laboratories and modelling centres — experts in the development of value-added products
Four International Organisations

They manage large sets of data, originating from their own institutes and from other parties in their country, using a variety of data management systems and configurations.

BODC request (ASCII) format — your opinion

2010-02-10T14:15:00.003Z

Data standardisation, in terms of both parameters and file format, is essential in professional data management.

BODC distributes data in a variety of standard formats. One of these, our BODC request (ASCII) format, has been in existence since the early 1980s. It comprises several lines of fixed-length header information (basic metadata) followed by the data cycles (and associated quality control flags) listed one per line.

BODC request (ASCII) format — change required ©

Until now we have refrained from changing this standard, as we were aware that our regular users had developed code for automatic data handling. Increasingly, however, the header design is limiting the information we need to present as well as being out of sync with standards elsewhere.

As part of our continuing commitment to improve our service to the marine community we feel that now is the time to consider a major update to our ASCII data format and we would value your opinion.

Such a change may cause inconvenience so we want to provide you with an opportunity to comment before we embark on an update. We would be pleased to hear your comments. When contacting us, please include information on the software you regularly use with this data format. This will help us tailor the design change to your needs.

New National Oceanography Centre (NOC) covers marine science from the coast to the deep ocean

2010-02-04T14:38:00.003Z

A new, national research organisation that will work in partnership with the UK marine research community to deliver integrated marine science and technology from the coast to the deep ocean goes live from 1 April this year.

The National Oceanography Centre (NOC) will be formed by bringing together into a single institution NERC-managed activity at the National Oceanography Centre, Southampton (NOCS) and the Proudman Oceanographic Laboratory (POL) in Liverpool.

The NOC will work in close partnership with the wider marine science community to create the integrated research capability needed to tackle the big environmental issues facing the world. Research priorities will include the oceans' role in climate change, sea level change and the future of the Arctic Ocean.

Integrated research — to tackle the big environmental issues facing the world. ©

A major element of the new approach will see the designation of a set of Partners of the NOC — comprising research institutes and key university groups — working collaboratively to support world-class strategic research, technology development and training the scientists of the future. Together with a wider group of Associates, these organisations will form the NOC Association, sharing in the delivery of a community developed strategy for marine science.

The NOC will have a key role in providing national capability to meet the needs of the whole UK marine research community including Royal Research Ships, deep submersibles and advanced ocean technologies. It will also be home to the global mean sea level data archive, the UK’s sea level monitoring system for flood warning and climate change, the national archive of subsea sediment cores and the British Oceanographic Data Centre (BODC).

How does this affect BODC?

As a national facility for storing and distributing marine data this initiative provides a strong framework to further our commitment to act for the entire community. We provide a resource for science, education, government and industry.

We are working hard to improve our data services and the way in which you can access and download data and information from our web site. For example, there are almost 68,000 data series available online from the National Oceanographic Database (NODB) 'online shopping' facility, with the number typically increasing at about 1,500 a month. This opens the way to the secure delivery of BODC's data holdings via various external data portals.

Open Service Network for Marine Environmental Data (NETMAR)

2010-01-28T11:24:00.002Z

The British Oceanographic Data Centre (BODC) is participating in the Open Service Network for Marine Environmental Data (NETMAR) programme, which will help provide a framework for marine environment data portal harmonisation and interoperability across Europe.

The objective is to provide a software toolkit for building data portals in a consistent manner. The toolkit will be developed through the use of emerging web standards, such as chained Open Geospatial Consortium (OGC) Web Services.

An example of a service chain ©

The end product will be configurable by user communities interested in developing a data portal and will offer search, download and integration tools. Further processing of data will also be available in order to provide derived products suitable for decision making in the marine environment community.

NETMAR is a European Union Framework 7 funded programme, which will bring together seven organisations from four countries to achieve its goal. It starts in February 2010.

What is our role?

In order to make the resulting portals truly interoperable, NETMAR requires a detailed definition of the services being called and the data requested. This will be achieved through the development of a multi-domain and multilingual ontology of environmental data and information services, to allow searches across human language and scientific domains.

BODC, building on the experience of the Enabling Parameter Discovery and NERC DataGrid (NDG) projects, will be involved in the development of these semantic web ontologies.

This will allow 'smart discovery' when searching for data. For example, searching on the word 'precipitation' or 'précipitation' in a data portal would return all data labelled with, say 'rain', 'pluie', 'snow' or 'neige'.

New GEBCO bathymetric grids released

Iceland to Scotland: crossing the Nordic Seas gateway

2009-07-16T11:31:00.007+01:00

Two BODC data scientists (Mark Hebden and Julia Calderwood) participated on both legs of the RRS Discovery 340 cruise in the North East Atlantic Ocean.

Mark compiling quality metadata ©

On the first leg, between Iceland and Scotland, they joined colleagues from the Scottish Association for Marine Science (SAMS) and the National Oceanography Centre, Southampton (NOCS) to monitor the Atlantic waters flowing north towards the Arctic Ocean. This work is performed annually under the Extended Ellett Line project; an ocean monitoring initiative that dates back to 1975.

The second leg of the cruise, around Western Scotland, examined how stratification and turbulent mixing are influenced by shelf topography, and the consequences for pelagic and benthic biogeochemical processes. This study was performed by scientists at the Scottish Association for Marine Science, with Oceans 2025 funding.

Mark and Julia were onboard RRS Discovery to assist with the sampling programmes, and to compile quality metadata records.

For more information about life onboard this research cruise, see the RRS Discovery 340 cruise blog.

UK Severe Storm - download near real-time sea level data from BODC

2008-03-09T20:53:00.001Z

Forecasters at the UK Met Office have issued severe weather warnings for much of the UK from Sunday to Tuesday. Winds of 70 m.p.h. are expected across southern and western parts of the British Isles with perhaps up to 80 m.p.h. in exposed areas as severe weather brings the risk of high waves and flooding.

The Environment Agency has issued a severe flood warning for the whole of the Devon and Cornwall coast amid storm warnings for south and west Britain.

Near real-time sea level data from the UK Tide Gauge Network is available for download from the British Oceanographic Data Centre(BODC).

High waves and flooding forecast ©

The UK National Tide Gauge Network of 45 tide gauges was set up as a result of severe flooding along the east coast of England in 1953 and is now owned and funded by the Environment Agency.

The Tide Gauge Network forms part of the National Tidal & Sea Level Facility (NTSLF). NTSLF is hosted by the Proudman Oceanographic Laboratory (POL) and BODC is responsible for the management of the tide gauge data and their access via the web.

The NTSLF was established in 2002 to reflect the importance of national sea level monitoring to the public and government, as well as to the academic community. Quality controlled processed data are available for download — free of charge.

More about RaTS

The RaTS programme is funded by NERC. It involves the long-term monitoring of a nearshore marine environment in the Antarctic. Its aims are to

aid interpretation of the local ecology
test a series of hypotheses concerning interactions between surface and deep waters and the environmental forcing of the nearshore environment

Sampling began in January 1997, at a site (Site 1) approximately 4 km from the coast of the BAS station at Rothera. Weather and ice permitting, an upper open hydrographic cast and discrete water sample (at a depth of 15 m) are collected every fifth day during summer and every seventh day during winter.

If Site 1 is inaccessible then the secondary station, Site 2, is occupied; if neither are accessible then a water sample is collected near the wharf at Rothera (Site 3) but no hydrography cast is taken.

Secure Sockets Layer (SSL/https) connections to protect your personal data as it traverses the web
protection from Denial of Service (DoS) attacks

Our Information Technology (IT) infrastructure (servers and networks) are maintained by our local IT support group (POL Computing). In turn, POL Computing are supported by NERC's IT Solutions & Services (iTSS) who provide specialised expertise.

We will continue to work closely with these groups to maintain and develop the IT infrastructure we depend on as part of our commitment to improving access to our data holdings and web services.

BODC celebrates 40 years

2009-04-24T15:29:00.006+01:00

This month marks BODC's 40th birthday. Our history began in April 1969 when the Natural Environment Research Council (NERC) created the British Oceanographic Data Service (BODS), located at the National Institute of Oceanography, Wormley, Surrey.

Over last the 40 years we have witnessed many changes; these include our name, location and organisational structure, the evolving nature of data collected by the science of oceanography and the technology we depend on.

However, our fundamental role as a national facility for preserving and distributing marine data has remained constant.

The changes - a brief timeline

April 1969 — The British Oceanographic Data Service (BODS) created — primarily to handle hydrographic data.
1975 — BODS transfers to Bidston Observatory, Wirral as part of the newly formed Institute of Oceanographic Sciences. The National Oceanographic DataBank (NODB) is developed, a batch-based COnference on DAta SYstems Languages (CODASYL) system running on a Honeywell computer, located at their offices in Acton, London. Our Parameter Dictionary is born.
1976 — BODS is the focus of a high-level review of offshore industry requirements. As a result, BODS becomes the data banking section of the Marine Information and Advisory Service (MIAS). MIAS-DBS is funded by NERC and the Department of Energy and Industry. Its primary activity is to manage data collected by the UK Offshore Operators Association's (UKOOA) network of weather ships, oil rigs and large-scale data buoys.
1977 — A Honeywell 66/20 mainframe computer is installed at Bidston Observatory.
1979 — MIAS becomes involved in international initiatives designed to standardise data curation.
1980 — The Honeywell computer is upgraded to become a model 66 type 60B, with 512KB of memory, 1.3MB of disk storage and six magnetic tape drives.
1982 — The in-house transfer system is developed; data inventories are accessible via Fortran programs and data are quality assured using paper or microfiche plots.
1985 — We spend £5000, the equivalent of six months' Data Scientist salary at that time, to purchase our first personal computer.
1987 — The arrival of the IBM 4381 computer (costing £400,000 — with 7.5GB of disk storage) and the Oracle Relational Database Management System (RDBMS). We begin to develop in-house visualisation software on two Silicon Graphics workstations (costing £40,000 apiece) to aid quality assurance. Data are still archived onto magnetic tapes.
April 1989 — the MIAS-DBS is restructured and renamed BODC.
1989 — An 'end to end' approach, working alongside marine scientists during the lifetime of projects to ensure good data management practices, is developed during the first NERC Community Research Project, the North Sea Project. The NODB samples schema is designed to store discrete samples, such as biological and chemical data from water bottle rosette systems. Our involvement in international project data management begins. An extra 5GB of disk storage is purchased for the IBM 4281 computer.
1990 — Work begins at BODC to develop and maintain the General Bathymetric Chart of the Oceans (GEBCO) Digital Atlas on behalf of the GEBCO community. Our Parameter Dictionary has expanded to contain around 5,000 parameters.
1992 — BODC adopt a UNIX system and data are archived in a Mass Store, a hierarchical storage system. BODC make data available to the marine community via its first CDROM product.
1993 — We undertake quality assurance responsibilities for UK Tide Gauge Network (DATARING) data.
1995 — Our first web presence.
1996 — During the year BODC service 1,035 customer requests for data and information.
2000 — The BODC web site is launched, providing online data catalogues and inventories of our data holdings. The additional functionality helps increase the number of annual requests to 4,644.
2002 — BODC develops formal partnerships with NERC’s marine research centres to encourage good data management practices.
2003 — Our Parameter Dictionary expands rapidly to almost 19,000 parameters.
2004 — We move to our current location, the Joseph Proudman Building, located on the University of Liverpool campus.
2005 — Our current web site is launched, providing expanded functionality.
2006 — The BODC Parameter Dictionary becomes available online through the NERC DataGrid Vocabulary server. Our online data request facilities are updated to include GIS map search facilities.
2007 — We complete an extensive modernisation of our visualisation and data handling software, enabling improved efficiency and portability, thereby enabling use by external users.
2008 — As part our role serving the national and international marine community we host and maintain twelve data portals and web sites.
2009 — Continual improvements to our web applications and functionality means that we now service ~100,000 requests for data and information per year. The next step is to provide an online 'shopping' facility allowing users to select data for auto-delivery from our entire data holdings.

Our continuing commitment

We are looking forward to meeting the challenging needs of marine data management in the future as data are precious; they are fundamental to the understanding of the processes that control our natural environment.

The data we hold helps provide answers to local questions or planet-wide issues, such as the prediction of the impact of global warming - something that not only affects us, but will also affect the quality of life of our children and grandchildren. The better we can predict these events, the better we can protect ourselves in the future.

* information about the GEOTRACES programme

GEOTRACES is an international programme that aims to improve our understanding of biogeochemical cycles and large-scale distribution of trace elements and their isotopes in the marine environment. The global field programme will run for at least a decade and will involve cruises, run by a variety of nations, in all ocean basins.

Although still in its infancy, the GEOTRACES programme's aim is to compile a global dataset for all key GEOTRACES parameters. This dataset will eventually be available to the wider science community in accordance with the GEOTRACES data policy.

Edward Mawji has been appointed the BODC coordinator. He will be working closely with the GEOTRACES scientists to establish common metadata and format protocols and will also be responsible for the quality control and secure archiving of data that will be collected during cruises.

Exploring the ocean floor with Google Earth

If you could peer beneath the ocean waves and glimpse the seafloor far below, you would see deep basins, vast mountains chains and long trenches. This is known as bathymetry.

Understanding bathymetry helps us understand the rest of the planet as this landscape helps steer ocean currents that in turn affect climate change. It also influences hazards facing coastal communities, such as approaching tsunamis.

The General Bathymetric Chart of the Oceans (GEBCO) community has been working for many years to provide the most authoritative, publicly-available bathymetric data sets for the world’s oceans. The recently released GEBCO 30 arc-second bathymetric grid (GEBCO_08) has been used as a basis for the 3D model of the oceans within Google Earth 5.0, to allow us to view the underwater landscape.

The GEBCO_08 bathymetric grid has been developed using a combination of ship track soundings and satellite-derived gravity data.

The GEBCO_08 Grid and the GEBCO One Minute Grid are both available to download from the British Oceanographic Data Centre (BODC).

GEOTRACES International Data Assembly Centre (GIDAC)

The British Oceanographic Data Centre (BODC) has been chosen to host the GEOTRACES International Data Assembly Centre, which is funded by the US National Science Foundation and the UK Natural Environment Research Council.

As part of this commitment, BODC will receive data from national oceanographic data offices and compile datasets for all GEOTRACES key parameters.

Edward Mawji has been appointed the BODC's coordinator. He will be working closely with the GEOTRACES scientists to establish common metadata and format protocols and will also be responsible for the quality control and secure archiving of the data that will be collected during cruises.

GEOTRACES is an international programme focused on understanding biogeochemical cycling of important trace elements and isotopes in the oceans. It is anticipated that the programme will run for approximately ten years and involve in excess of twenty research cruises, run by a variety of nations.

BODC participates in the HUMBOLDT project

2008-11-05T16:02:00.007Z

The British Oceanographic Data Centre (BODC) is participating in the HUMBOLDT project, which will help provide a framework for geo data harmonisation and service integration across Europe.

The objective is to build and test tools to allow organisations to exchange data and information more easily, with the aim of enabling an improved response to disaster management.

More information is available from the BODC HUMBOLDT project pages.

What is BODC's role?

One of the key tasks within the HUMBOLDT project is to test the architecture and tools created. To achieve this objective various scenarios will be developed and applied under realistic conditions, for example: an oil spill in international waters.

BODC's involvement is in adapting an existing operational oil spill model. This is being carried out in collaboration with the National Centre for Ocean Forecasting and will use live feeds of ocean currents and weather provided by the Met Office.

The model will be used to test the software components developed by the HUMBOLDT team in other work packages, focusing on interoperability between oil spill models, thus allowing data and information to be exchanged easily in the event of an international incident.
