Seabed 2030 Project Overview The Nippon Foundation – GEBCO Seabed 2030 Project Seabed 2030 Project Overview OGC Marine Summit 27th February 2019 Presented by: Dr Thierry Schmitt Chair of the Technical Subcommitte on Ocean Mapping (TSCOM) EMODnet Bathymetry Coordinator Version 1.0 – submitted to IODE Science Conference on 11th Feb 2019 French Hydrographic Service (Shom), FR

What is GEBCO? ‘ The General Bathymetric Chart of the Ocean’ ‘… a joint project of IHO & IOC, managed by the GEBCO Guiding Committee (GGC)’ ‘…aiming to provide the most authoritative, publicly-available bathymetry data sets of the world’s oceans.’ ‘… largely a voluntary community of international scientists and hydrographers collaborating with the support of their parent organizations.’ GEBCO Guiding Committee

18 % complete What is GEBCO? 1 km If the World Ocean is divided into 1x1 km blocks (grid cells), about 82 % of them do not have depth values. (Based on GEBCO 2014 grid) 18 % complete

What is Seabed 2030? A collaborative project between The Nippon Foundation and GEBCO to inspire the complete mapping of the world’s ocean by 2030 and to compile all bathymetric data into the freely-available GEBCO Ocean Map. Mr Sasakawa, Chairman, The Nippon Foundation June 2016 June 2017

Seabed 2030 Preferred data flow Horisontal resolution: 1 km (1x1 deep-water multibeam) Horizontal resolution: 60 m Swath width: 14-17 km (1x1 high-res multibeam) Horizontal resolution: < 5 m Swath width: <500 m

‘Map the Gaps’ = ocean NOT mapped Seabed 2030 Phase 1: Existing data Ingest all available existing data (Y) Catalogue embargoed existing data (Y) Develop new high resolution GEBCO product Develop user tools for GEBCO products X = 18 % complete GEBCO 2014 30-arc second Grid X + Y + Z = 100% Data IN GEBCO Data NOT in GEBCO ‘Map the Gaps’ = ocean NOT mapped

Phase 2: Mapping the Gaps Seabed 2030 Phase 2: Mapping the Gaps X + Y + Z = 100% Technology Innovation What can Seabed 2030 do to accelerate uptake of technology to accelerate rate of bathymetric mapping? Map the Gaps Use GEBCO Grid to inform location of future mapping Advocate for greater mapping activity Identify funding for mapping expeditions

Seabed 2030 Why Now? The need: Ocean under stress UN SDG-14 Solutions: innovation Big Data The Cloud IoT Open Data Information Technology Autonomy

How OGC can get involved Seabed 2030 How OGC can get involved Help us facilitating data sharing/interoperability through metadata, data format and any innovative ways to disembargo protected data Help us finding innovative ways to aggregate world-wide dataset in an efficient manner (DGGS) Help us implementing new ways of working collaboratively (Web services, cloud computing) on the wide range of dataset (raster, point cloud, vectors) Bathymetric data is a key information which sustain a wealth of other sciences and societal themes (ocean, climate, biology, defence, transport, …). Help us promoting this geospatial information which describes 2/3 of the earth surface.

March 2019 Seabed 2030 Upcoming events GEBCO 2019: Release of GEBCO 2019 – coming soon……… GEBCO 2019: GEBCO 15-arc second grid Future versions will go to multi-resolution grid (GEBCO 2020?) March 2019 What will % coverage be?
