What is SeaRISE?
Sea-level Response to Ice Sheet Evolution (SeaRISE) is a community organized effort to estimate the upper bound of ice sheet contributions to sea level in the next 100--200 years. SeaRISE objectives include
- developing a set of common input data. These efforts are available from the Data portion of this wiki.
- designing and executing a set of numerical experiments employing a wide range ice sheet models. A notional list can be found in the SeaRISE White Paper; details of actual agreed-to cases are found in Experiments.
- refining details of rapidly responding areas in particular experiments with ice stream/ice-shelf or ice-shelf/ocean regional models
Participating models will compare output to determine both the contribution to sea level, as well as associated uncertainties.
What's new / What happened?
- A SeaRISE White Paper (circa 2008) describes the general approach and is available on this wiki.
- Regular telecons  began October 2008 and are accessible online. These are being hosted at the LANL trac site, where there are also notes on other working groups, meetings/workshop, and links to related efforts .
- The Data continue to undergo refinement, and this page should be checked frequently.
- Ready, set, MODEL! Sensitivity Experiments for the Greenland and Antarctic ice sheets have been completed by the SeaRISE participants and model simulations are now available to the scientific community. Publications describing the effort and results are available from the wiki.
- SeaRISE participants are starting to define the next steps for the effort, so keep an eye open for news on the new wiki...
Just how does this work?
One of the core missions of the SeaRISE effort has been to establish common model inputs. Those can be found in the Data portion of the wiki.
Bringing an ice sheet model into a present day configuration is a challenge. If the model is computationally efficient enough, it is possible to subject the model to a glacial cycle to approach the present state in a dynamic way. Guidelines for doing this are located on the Model Initialization pages.
The second core mission of SeaRISE is the formulation and execution of numerical experiments that will inform sea level rise estimates. Those experiments are specified on the Experiments pages.

What's a wiki?
This is a wiki (what I know is...), which means that the content is developed collaboratively. In the upper right corner of the window, there is a link to log in. If you do so, you can register an account. After registering, you should receive an email. Clicking on the link in the email will verify your identity, and you can then alter the contents of the wiki.
You are encouraged to use the wiki pages to alter the formulation of numerical experiments, point out any inconsistencies or inaccuracies you find in the data sets, and post results and figures that you'd like others see and discuss.
Wiki editing is like other markup languages, such as HTML, or Latex, but mostly easier. If you're accustom to writing equations in Latex, you'll find it very comfortable. This is link to a wiki editing guide, and much of what you need to know can be learned by looking at the source of other wiki pages, including those at Wikipedia.
As the assessment effort has progressed, firm commitments to participate in the experiments have emerged. These pages contain information about participating models, and their characteristics.
