Supersites Coordination Workshop

Brussels, June 10, 2013

Objective


… to reduce the vulnerability to geological hazards by improving the scientific understanding of hazardous events through worldwide scientific collaboration.

Supersites Strategic Plan (2011)

GEO Work Plan 2012-2015, Task DI-01-C2

Support the establishment of Supersites and Natural Laboratories.

Provide an electronic infrastructure allowing easy access to data (space & in-situ) and a wide range of tools, and a platform for on-line collaboration. Develop a consolidated Supersites Strategic Plan.

Objective

1. Global network of geohazard natural laboratories, consisting of sets of natural laboratories for Europe/Africa, the Americas and Asia/Oceania.

2. Seamless access to seismic, GNSS and SAR data for each of the natural laboratories.

3. Comprehensive multi-sensor SAR data acquisition plans: background acquisitions using low-resolution SARs and targeted acquisitions of specific sites using high-resolution sensors, maximizing the synenergy with in-situ networks.

4. Community-provided software applications for scientific data analysis using a Cloud e-infrastructure.

request

Free and open access to data for Supersites use

Types of Supersites


Permanent Supersites• Highest priority• Threat to humans and/or critical facilities• Scientific investigations aim at understanding processes

Candidate Supersites• … are Permanent Supersites under development.

Event Supersites• Recently affected by major geological event• important and rare opportunity for scientific investigation• Substantial scientific interest internationally

Natural Laboratories• Potentially larger areas• Potentially less densely monitored

Event Supersite selection


SAC Chair, Steering Committee Member, or Permanent Supersite PI nominates Supersite

Supersites Steering Committee accepts Site

CEOS Selection Criteria

recent earthquake, severe volcanic unrest or similar

important and rare opportunity for research

event motivates substantial scientific interest and investigations

Event Supersite benefits from space and in situ data made available


European Projects and the GSNL

MARsite, FUTUREVOLC, MED-SUV are contributions to the GEO GSNL

The projects

make use of and benefit from the GSNL

may supply the Supersite PI

Point-of-contact for Supersite – goes beyond EU project!

Interface to CEOS agencies

organize data access within the Supersite science team


Summary on GSNL


support focused scientific research on geohazards

Initial sites selected

Evolving and maturing – EU projects contribute

Coming next:- More locations and hazards- More data resources- Computing platforms
