Descr: I am continuing to operate 3 broadband seismic stations from the CRSEIZE experiment on the Nicoya Peninsula in Costa Rica to augment coverage for the Abers/Fischer ongoing experiment. While my project has ended and I am not funded, Abers/Fischer are funded by NSF. I am only requesting GPS clocks to keep these stations running and I will cover the cost of shipping these to UC Santa Cruz. If these clocks can arrive at UC Santa Cruz by the AGU meeting (Dec. 13), they can be hand delivered to Costa Rica by our scientific collaborators who will be at the AGU meeting in San Francisco.
