The field trip, hosted by Scott Burns (Portland State University) and Jim O'Connor (USGS), will provide attendees with the opportunity to visit the Columbia Gorge to the east of Skamania Lodge to see the geology and past geological processes for this beautiful area. The first stop at Cascade Locks will focus on the most famous landslide in the Pacific Northwest, the Bridge of the Gods Landslide plus a new landslide this winter off of Greenleaf Peak. Buses will then make their way up the gorge toward the Hood River discussing geological hazards of landslides and rockfall and flooding. Interesting volcanic outcrops will be seen near Hood River. In Hood River we will stop to see the new delta in the Columbia River created by the debris flows on Mt. Hood in November 2006. The final leg of the trip will include a stop at Rowena Overlook where attendees will learn about the Missoula Floods, the tectonics of the area, and mima mounds. On the way back to Skamania Lodge, we will stop in Hood River at a winery to sip the local wines and talk about terroir - the relationship between soils, geology, climate and wine.
A separate registration fee of $35 is required to participate in the field trip. Seats are limited.

Station footprints for EarthScope Magnetotelluric (MT) stations will be prioritized with respect to key tectonic processes exemplified in the US and in accord with the national USArray passive seismic coverage. Travel support is offered but attendance is limited; those interested should contact Phil Wannamaker at pewanna@egi.utah.edu.
The Controlled-Source Seismology Community in the US has held a series meetings over the past months and formed an IASPEI U.S. National Committee on Controlled-Source Seismology that spans all scales of the application of controlled-source techniques. The goals of this organizations include: facilitate controlled-source experiments and their interpretation; promote controlled-source capabilities and integration with other scientific communities; develop innovative experiment designs; a knowledge base of best practices for fieldwork; software development and sharing; and a forum for discussions of needed technological developments; enable access to industry data and expertise, facilitate academic - industry interactions; develop plans for national field project support (i.e., manpower and equipment); support of the U.S. research-and-education community, with an emphasis on continental controlled-source seismology; and be open to anyone wishing to support these goals, and provide information regarding current progress that is easily accessible through a web site. The purpose of this workshop is to gather the Controlled-Source Seismology community and discuss how to pursue these goals and move forward.

This year, the DMC tutorial will highlight jWEED, a map-based client application that lets you receive waveforms for earthquakes with user selectable attributes. The attributes include geographic location, time and magnitude as well as several event-station attributes (distance, azimuth, path). A user does not need to know which stations were operating at the time of the earthquakes. By leveraging information stored at the DMC, jWEED eliminates administrative burdens like calculating travel times and writing the email request format called "breq_fast". We will show users how to use jWEED to generate either batch requests or pull the data back to their workstation interactively. After a thorough tutorial on JWEED, we will solicit input from users as to how JWEED can be improved to meet your data requirements. This feedback will help to ensure that the IRIS user community is well served by the tools that the DMC has to offer. DMC staff will be on hand to answer any questions you might have during this short course.

IRIS-DMS will sponsor a one-day tutorial on how to utilize multi-node parallel computing by using the MPI (Message Passing Interface) library within your geophysical software codes. Many of us have access to in house or campus multi-processor computers. However, in order to access many computing nodes at one time, particularly those distributed across a cluster, our software codes need to be programmed to ask for and to compute on the many nodes. Currently the most commonly used method to perform this task is MPI, a set of library calls that performs the communication to the multiple processors. MPI enables an application code to access from two to 512+ nodes (desktops to national supercomputer sites). The full-day pre-workshop tutorial will provide an overview of multi-node parallel computing strategies including one-task-many times (e.g., thousands of cross-correlations) and one-task parsed and distributed across many processors (e.g., 3D finite difference algorithm). Future directions of parallel computing will also be discussed. MPI basics will be presented. During the tutorial, participants will gain hands-on experience of writing simple codes containing MPI and then on how to run these codes. Tutorial instructors will provide access to a multi-node facility at their national computing centers; participants should be familiar with UNIX/Linux and either C or Fortran.
