RAPID: Funds to Complete Seafloor CORK Instrument Sleds for Imminent Deployment

PI请求MRI资金，以帮助完成3个仪器滑架的制造，计划于2011年秋季在North Pond部署。 需要RAPID请求的紧迫性是由于执行工作、彻底测试滑轨以及纠正/改善在长期测试阶段发现的不可避免的问题所需的提前期。私家侦探？我们认为，如果他们等待重新开始制造，他们将危及一个独特的机会，即在IODP在大西洋中脊西侧的北池安装了三个CORK天文台后，观察地下室环境的重要变化。热液流体的循环深刻地影响了洋脊侧翼和海盆的老化基底的化学和物理演化，并导致全球显著的热通量，上覆海洋的化学通量和动态微生物。拟议的项目开发创新的，多功能的仪器，用于研究这个偏远的，极端的生物圈，提供强大的采样/实验机会，提供访问原始基底流体。更广泛的影响：该项目结合了先进的技术开发与令人兴奋的前沿科学。许多研究生和本科生接触到整个开发过程以及仪器滑架的部署和科学输出。

The PI requests MRI funding to help complete the fabrication of 3 instrument sleds intended for deployment at North Pond in fall, 2011. The urgency necessitating a RAPID request is due to the lead time required to perform the work, thoroughly test the sleds and to correct/improve inevitable issues discovered during the prolonged testing phase. The PI?s feel that if they wait to restart the fabrication they jeopardize a unique opportunity to observe important changes in the basement environment following the installation of the three CORK observatories at North Pond, on the west flanks of the Mid Atlantic Ridge by IODP. The circulation of the hydrothermal fluids profoundly influences the chemical and physical evolution of the aging basement of the ocean ridge flanks and basins, and results in globally significant heat flux, chemical fluxes to the overlying ocean, and the dynamic microbiospere. The proposed project develops innovative, versatile instrumentation for studying this remote, extreme biosphere, providing robust sampling/ experimental opportunities with respect to providing access to pristine basement fluids.Broader Impacts: This project combines advanced technology development with exciting frontier science. Numerous graduate and undergraduate students with bee exposed to the whole development process as well as to the deployment and science output of the instrument sleds.
