mapping Brendan DollardEnvironmental TechnologistCleanTechEnterprise Ireland
• Development of automated predictive models of the Irish Sea
and selected inshore regions
• Website will be developed to display the output from the
models developed within PRISM.
• Website will be developed to allow end users to make “what
if” calculations on environmental issues.
• Website will be developed to promote the tourism and leisure
industries by providing forecasts of wind, sailing and surfing
conditions.
Objectives of the PRISM project
Overview of the Prism.ie System
Provides easy to interpret map access to output from Irish Sea computer wave and hydrodynamic forecast models.
Dynamically reads output from models that run on a daily basis and prepares these for web viewing.
Allows model data animation - scroll through six hourly forecast.
Graphing of detailed data at key locations. Provides a technology approach that is readily extendible
to other models and applications.
Models in PRISM
Irish Sea model – POLCOMS NE Atlantic model – ECOMSED Dublin Bay model – SWAN, DIVAST
• Forecast outputs: 48 hrs time period covered

Automation - overview
• Machine specification - 32 bit IBM XSERIES_255 server
- operational system: LINUX
- 8 processors Intel(R) Xeon(TM) MP CPU 3.00 GHz
• Timing - ~ 70 minutes for POLCOMS model (1 processor)
- ~ 125 minutes for ECOMSED models (1 processor)
- ~ 95 minutes for SWAN models run in parallel (6 processors)
- ~ 25 minutes for DIVAST model (1 processor)
- < 2 minutes for pre-processing - ~ 5 minutes for post-processing and uploading to ftp site

Request
Outlines the steps in polling, download, parsing, loading, optimising of model data. Importantly this dynamically creates raster layers of the model results and optimises
these for web display. Dynamic creation of wind vectors also is facilitated.

Outcome
A web based system useful in its own right. Capable of extension to other sea areas –
computational models are already largely in place. System approach allows ready extension to other
computational models (river, air, noise, transport). Delivered under a research project and now an
operational system.
A better understanding of the environment through the use of computer models that will result in practical tools suitable for use in planning and management decisions.
The results and tools that are being developed within the project have been placed on web pages that the public will be able to access. One aspect of the work will concern safety at sea and the education of the public to the dangers that are inherent in marine leisure activities.
Benefits
The project was highly successful in its goals of developing ocean modelling expertise in both Ireland and Wales, in producing operational forecasts that can be viewed by the public via dedicated web pages, and in creating a networking environment that brought together a community of researchers and end users.
