CCMP By-Laws
The Draft of CCMP Governance Rules has been pre-approved by the CCMP Steering Committee and is now available for the CCMP Members to explore. Please login as a Member at our web site and take a look at the Draft. We are most interested in your comments and suggestions. In two months the draft will be put up for a vote by the Membership and will be enacted if approved.
Dave Potsiadlo takes off on new career
With much chagrin we announce the departure of the CCMP administrative assistant, David Potsiadlo. Dave was instrumental at making CCMP happen on the web. With his arrival the CCMP acquired the look and feel that we enjoy today. More recently he has made a huge jump mastering the more advanced web programming skills that brought a whole new level of functionality to our web pages.
We enjoyed working with you, Dave. Best wishes in your future work.
LTRANS
Yet another addition to the CCMP family of open source models - LTRANS, the Larval TRANSport Lagrangian model is an off-line particle-tracking model that runs with the stored predictions of a 3D hydrodynamic model, specifically the Regional Ocean Modeling System (ROMS). LTRANS has also been implemented for a finite element hydrodynamic model (QUODDY) but the code is not ready for release. Although LTRANS was built to simulate oyster larvae, it can easily be adapted to simulate passive particles and other plantonic organisms.
LTRANS is written in Fortran 90. It includes a 4th order Runge-Kutta scheme for particle advection and a random displacement model for vertical turbulent particle motion. Reflective boundary conditions, larval behavior, and settlement routines are also included. LTRANS was built by Elizabeth North and Zachary Schlag of University of Maryland Center for Environmental Science Horn Point Laboratory.
Check out the project web site Community modeling, data and model interoperability", organized among others by two CCMP Board members - Chris Duffy and Alexey Voinov.
The session focused on several issues relevant to CCMP, such as:
- Understanding the interoperability needs of the community in a participatory and collaborative effort
- Developing research scenarios that would benefit from interoperability. Build consensus about interoperability architecture and standards supporting these scenarios
- Expanding on environmental system observatory ontologies, in particular for mapping variables to concepts
- Discussing common access protocols, enabling models to automatically search for data needed and link to data servers. Design data interoperability for model input/output to help link models.
Other sessions at the conference included such topics as Data and sensor networks and environmental modelling, Intelligent Environmental Decision Support Systems, Integrated Catchment Management: How can modelling tools and techniques help?, Participatory and Conceptual Modelling – Making Models Amenable to Stakeholders’ Concerns, OpenMI applications and innovations, Environmental Modelling and Decision Support Systems, and others. The proceedings are available from the conference web site.
