GEBCO Data Store
• A repository for bathymetric trackline and gridded data used to produce the GEBCO grid
• Differs from other data repositories because it seeks already-processed data; preserves users efforts
• Data contributions:– Public (free, open access)– Already processed and/or gridded/decimated– Grid cells flagged with constraint information– Metadata– Attributed to source organizations to encourage contributions– Low resolution versions of proprietary high res data
• Two-way access to data

GEBCO Data Store: Progress
Metadata Editing Made Easy (MEME)
• Web application tool that will enable contributors to easily create acceptable metadata and submit data through an HTML form
• Gathers information for data discovery, flag Source Identifiers (SID), and automatically generates high quality, ISO compliant metadata
• TSCOM members are providing data format and metadata guidance

IHO-IOC GEBCO Cook BookAt the 2009 GEBCO 25th Meeting of TSCOM, the “Cook Book Working Group” was formed to “create a manual that enables users to prepare and grid data for inclusion in GEBCO products,” resulting in:
• IHO-IOC GEBCO Cook Book published:- IHO Publication B-11 (April, 2012)- IOC Manuals and Guides, 63 (Oct. 2012)
• Available for Download: http://www.gebco.net
• EOS “News Brief” announcing Cook Book was published in EOS Trans. AGU, Feb. 2013
• Continually updated with new contributions, current version November 2013
• Article in Hydro Int’l (April, 2014) highlights Cook Book
• Used as educational resource, including:- UNH CCOM/JHC Ocean Mapping classes- Texas A&M University- used internationally

GEBCO Hi-Res Product• GEBCO Hi-Res is a prototype effort to create a new high resolution GEBCO product
• Global Multi-Scale Resolution Topography (GMRT) is a synthesis of terrestrial and seafloor
elevation data in image and grid form that can be viewed in various resolutions
• GEBCO_08 grid is combined with LDEO compilations and contributed grids
• Users can zoom-in, view data attributes, and access data
