Dust and Chlorophyll over the Mediterranean

GEOSS Web Services (GWS) Interoperability Demostration

Presented at the workshop

The User and the GEOSS Architecture

July 22, 2007, Barcelona, Spain


Ocean fertilization by atmospheric dust

Phytoplankton produce most of the oceanic biomass through photosynthesis

Photosynthesis by chlorophyll has been shown to increase with atmospheric dust fertilization

Ocean Fertilization by Atmospheric Dust

Oceanic Biomass by Phytoplankton

Evidence of Chlorophyll Enhancement by Dust

N. Pacific Ocean

Bishop et al.(2002), Science

E. Mediterranean

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.
