The InterRidge Office is calling for articles to be included in this year's InterRidge News, Vol. 21, published in November 2012, and we would very much like to hear from contributors. Suitable material includes preliminary results of research related to ridges, back-arc basins and ophiolites. Also, we are looking for general articles on shipboard or immediate post-cruise results, new equipment, opinion articles and workshops reports. In particular, we would want you to supply 1-4 high resolution images with any article (minimum pixel width = 1000). InterRidge News is intended for the rapid publication of preliminary results and cruise reports that do not appear in other publications. All articles and images must be submitted by email to the InterRidge Office (firstname.lastname@example.org) by 1 September 2012. Please see the following webpage for formatting guidelines: http://www.interridge.org/IRNewsletter/formatting If you intend to submit an article, the IR Office would appreciate knowing in advance.
