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

2. 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

3. 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

4. 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.

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

6. ‘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

‘Map the Gaps’ = ocean NOT mapped

7. 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

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

9. 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.

10. 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?)
