Currently there are over 2800 scientists active in mid-ocean ridge research on our mailing list. We are constatnly adding new entries to the electronic directory, which contains a listing of each researcher's field of interest and expertise as well as their full address information. Links are also provided to personal or departmental web pages. Vol. 11(1), 2002 3 InterRidge Office Updates The InterRidge Wishhhhhh List.... On suggestion of the IR Steering Committee, we have opened the InterRidge Wishhhhhhh list to facilitate and poromote sample exchange between ridge scientists. Please submit requests for samples, to the IR Office. Iwould like to encourage all ridge scientist to check the Wishhhh list and share samples with your international colleagues. The success of this initiative is dependent on YOU! Below are three requests for samples. If you have such samples to share, please contact the appropriate scientists. I wish I could get my hands on ........ Requested samples..... Request for: CHIMINEY SAMPLES Samples of manganese encrusted chimneys as well as hydrothermal or hydrogenous ferromanganese samples and associated sediments collected from any other midoceanic ridge system". Contact: Ranadip Banerjee <[email protected]> or <[email protected]> SEARCH FOR GRAPHITE Sediment trap deposits collected nearby vents, and/ or grab samples of particulates from vents (0.0X to 1 gram quantities). Old collections are OK. ROCK SAMPLES If such materials are available in your drawers, Rock samples from Laxmi Basin, Laxmi please contact: Jacques Jedwab continental block or any protruding seamounts <[email protected]> in eastern Arabian sea for physical/chemical studies Contact: A. Shivaji ([email protected]) I wish c uld get my ands on ..... Would you like to get your hands on certain samples; be they rocks, crabs or tubeworms! Send your ‘wish list’ to the InterRidge office and we will post it on the IR website and print it in the next issue of IR news.
