Dust and Chlorophyll over the Mediterranean GEOSS Web Services (GWS) Interoperability Demostration The User and the GEOSS Architecture Presented at the workshop July 22, 2007, Barcelona, Spain

Ocean Fertilization by Atmospheric Dust Oceanic Biomass by Phytoplankton Evidence of Chlorophyll Enhancement by Dust N. Pacific Ocean Bishop et al. (2002), Science Phytoplankton produce most of the oceanic biomass through photosynthesis E. Mediterranean Photosynthesis by chlorophyll has been shown to increase with atmospheric dust fertilization However, precipitation, the wind and many other factors also influence the production of chlorophyll A scientific challenge is to quantify the chlorophyll-dust relationship

Summary • GEOSS System of Systems architecture is suitable for integrating data across geographical, disciplinary and organizational boundaries. • The current data access standardization is very spotty and fragile but non-intrusive mediator services can bridge the interoperability gaps. • Interoperability demonstrations are key steps toward configurable, robust data flow and processing networks.

GEOSS Workshop/Demo at IPY Geo. North Yellowknife, Canada 19 -20 August 2007

GEOSS Workshop at Geo. North • Workshop Theme: “The Impact of Climate Change and Variability on Biodiversity and Energy in the Arctic " – Organized by Ellsworth Le. Drew (ells@watleo. uwaterloo. ca) • Workshop precedes the First International Circumpolar Conference on Geospatial Sciences and Applications, Yellowknife, N. W.

GEOSS Workshop at Geo. North Draft agenda for August 20 th, afternoon 13: 00 Session Overview - George Percivall 13: 10 Open Standards for GEOSS Interoperability - Doug Nebert 13: 40 GEO Web Portal Candidate - Robert Thomas 14: 10 Overview of biodiversity demonstrations - Geo. Connections 14: 25 Biodiversity Demonstrations Robert Thomas, Compusult; Greg Yetman, CIESIN; Roman Gerlach (for Stefano Nativi, IMAA - CNR) 15: 20 Closing Discussion and wrap-up George Percivall Helping the World to Communicate Geographically

Presentation by D. Nebert Open Standards for GEOSS Interoperability • • GEOSS Concept Requirements on GEOSS Contributed Systems Open Standards for Geospatial Interoperability OGC Web Services Standards meet GEOSS Architecture Requirements Major OGC Specifications for GEOSS Market Implementation AI Pilot: Portal, Clearinghouse, scenarios What to watch for in the demos Helping the World to Communicate Geographically

Demonstration/presentation by Robert Thomas Geo. Web Portal Candidate Presentation • Committed to Standards • Our Vision of the Geo. Web Portal • The Compusult WES Geo. Web Portal A suite of applications providing a real-time, web-based, geospatially enabled portal to provide centralized interoperability, discovery, collaboration, sharing, access and management over highly disparate information. • How WES is Currently Used – Selected Organizations using Web Enterprise Suite • WES Geo. Web Portal Architecture Overview • WES supports the following standards: • WES Platform Independence – WES X software components have been designed and implemented to operate across multiple platforms. Operating Systems currently supported: • WES: The Total Geospatial Portal Solution • Geo. Web Portlets included in WES – Discovery, Discovery agents, Viewer, Publisher, Administration, Colaboration, Other • Benefits of a WES Geo. Web Portal Helping the World to Communicate Geographically

Demonstration overview • 1 st role - need for study - development in a region – initial problem scoping with focus on discovery of data sets, establish AOI and saving as context – Could start with news story report using geo. RSS (Robert) – Sends context document to analyst/researchers • 2 nd role: relation of development to caribou – accepting context document, adding additional data and layers to help evaluate problem statement. – something like how might caribou migrations be affected by changes in permafrost, roads, etc. – be sure to include polar projections • 3 rd role: butterfly biodiversity – Existing demo from INAA-CNR Helping the World to Communicate Geographically

Part 1 - problem statement (Doug e-mail) • 1. Where is the highest potential for oil-gas development in areas that are not currently developed? Show energy geologic provinces of potential. Show existing oil-gas development. Show existing leases. Show land status (protected lands, open lands, etc). • 2. Identify areas that could be economically accessed as extensions to existing infrastructure (pipelines, roads) that are not protected lands. • 3. Identify caribou migration patterns and discern any potential conflicts of territory. • 4. Identify snow cover, surface temperature, and vegetation patterns relative to the migration of the caribou. Are there cause-effect patterns or pressures on the migration? Helping the World to Communicate Geographically

Scenario Ideas - Robert • 1) possible oil pipeline may cross Caribou migration routes. Prompts investigation into the effects on Caribou migration from Energy Exploration/Development in combination with Climate change Issues. A totally fictional (geo)RSS feed • 2) Robert contacts Greg because I knew he had some new pipeline data from the start of the environmental assessment. – Greg: You would have to mock-up some pipeline data going from the east end of Great Slave Lake to the Beaufort Sea. – Greg could save this as a context and send it back to me. • 3) We would perform additional discovery of the Caribou migration layers, ice extents, vegetation etc. These layers could be then added to Google Earth (GE) as the analysis client (at this point our client and map server doesn't support the Polar Projection). Basically, we could show the different seasonally migration and ice extents, plus any other relevant layers, in switch able layers on GE. • 4) Scientific Analysis: Now it gets into the scientific analysis and I would be way out of my depth to suggest anything here. • 5) Conclusions: Building a pipe line when combined with climate change creates a risk to Carbou calving areas? ? ? ? Helping the World to Communicate Geographically

2. Research oriented scenario ideas - Terry • we need to broaden our approach in this scenario. – Most of the biodiversity issues have very subtle long term cause/effect relationships that require examination of data from many sources and interpretation by applications experts. • storyline in this scenario could be that we put the tools in the hands of the applications experts to bring together many disparate datasets (including time series') – We may not know if there is a correlation of significance between datasets but our tools allow the applications experts to study these data in ways that have not been possible in the past. • The sea ice is a case in point. While the correlation between sea ice and caribou migration is not obvious, the caribou calving grounds are very close to the sea coast. Maybe there is a connection here?

GEOSS Demos Lessons Learned • Application-specific demos are a great way to engage with user communities that would not necessarily look to OGC standards. • Emphasize message about using distributed components with open standards vs. standalone application • Tremendous enthusiasm and commitment of agencies and research groups to collaborate • Demo provides a fast-track to skills development and knowledge transfer. • Live demo is compelling but dependent upon communications networks that may not be reliable at workshops • Live demo should be accompanied by a pre-recorded demo • Presentation of the demo works best with two projectors: one for the client application, the other for a powerpoint presentation explanation • Start early to get satellite data • Desirable to involve participants from the local region • Keep it simple, focus on the magic of interoperability • GEOSS Demos are persistent using OGC Network – http: //www. ogcnetwork. net/GEOSSdemos Helping the World to Communicate Geographically
