BODC upgrades network infrastructure

The British Oceanographic Data Centre (BODC) has recently upgraded its network infrastructure to cope with the demand on services. This investment will allow us to maintain our high standards in web data delivery, cater for the 30% year on year increase of registered web users and help us achieve our aim of making all of our data holdings accessible via the web.

Our recent network upgrade provides

  • dual fibre-based Gigabit connections to the internet for maximum resilience and redundancy for our web sites and services
  • load balancing between our web servers with Gigabit connections to the internet and back office application servers, giving a tenfold increase in available bandwidth
  • 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.

GDA Software Interface version 2.12 released

Version 2.12 of GEBCO Digital Atlas (GDA) software interface has been released. This supersedes previous versions and is available for download by existing GDA users, along with instructions on how to install and use the software.

The GDA is a reference source for the bathymetry of the world's oceans. It contains a global set of digital bathymetric contours, coastlines and gridded bathymetric data sets. It is accompanied by a software interface, which allows the user to display, query and export data from the various GDA data sets.

Version 2.12 of the software interface includes the following additional features

  • view and access data from both GEBCO gridded bathymetric data sets, the GEBCO One Minute Grid and GEBCO_08 Grid
  • export the gridded data in an ASCII format suitable for conversion to an ESRI raster file using ESRI data conversion software

The GDA is currently distributed on CDROM and does not include the GEBCO_08 Grid. An updated DVD product is planned for release shortly to include both gridded data sets.
