DuennebierOCE-0124603 Funds are requested for the design, construction and testing of a small experiment module (SEM) for use in ocean bottom observatories. The purpose of this module is to reduce the effort necessary to conduct relatively simple observatory experiments at the ocean floor. Ocean bottom observatories will soon be providing opportunities for investigators to conduct scientific investigations using power from the observatory and transmitting data to shore through the observatory. The interface between the observatory and the scientist's sensors is intimidating for many investigators, requiring consideration of sampling, filtering, digitizing, timing, power, and data formatting, as well as construction of sophisticated electronics, pressure vessels, buoyancy devices, and related hardware. The proposed module will greatly simplify this task, allowing investigators to concentrate on their science, rather than on engineering. While those investigators with engineering expertise available will not necessarily need such an interface, the installation of relatively simple experiments coupled to a SEM will be far less complicated, making it easier and more cost effective for many to participate in observatory science. We envision a package similar to the SEM available at nearly every science node of major ocean bottom observatories. The prototype proposed here should point out any shortcomings in our conceptual design for such a device, and establish its usefulness to the community. The prototype of this package will include ports for connection of up to twelve sensors, including an absolute pressure sensor for tsunami detection. It is proposed that the first SEM at the Hawaii-2 Observatory will be installed during the next visit to the site in 2002 or 2003. Future versions of the SEM can be modified to the needs of a particular observatory.

申请的资金用于设计、建造和测试一个小型实验舱，供海底观测站使用。该单元的目的是减少在洋底进行相对简单的观测实验所需的工作量。海底观测站不久将为调查人员提供机会，利用观测站提供的电力进行科学调查，并通过观测站将数据传送到海岸。天文台和科学家的传感器之间的接口对许多研究人员来说是令人生畏的，需要考虑采样，过滤，数字化，定时，电源和数据格式，以及复杂的电子设备，压力容器，浮力装置和相关硬件的建设。拟议的模块将大大简化这项任务，使调查人员能够专注于他们的科学，而不是工程。虽然那些具有工程专业知识的研究人员不一定需要这样的接口，但将相对简单的实验与SEM相结合的安装将不那么复杂，使许多人更容易参与天文台科学。我们设想一个类似于SEM的软件包，几乎可以在主要海底观测站的每个科学节点使用。这里提出的原型应该指出我们在这种设备的概念设计中的任何缺点，并确定其对社区的有用性。该套件的原型将包括多达12个传感器的连接端口，其中包括用于海啸探测的绝对压力传感器。建议在夏威夷-2天文台安装第一台扫描电镜，并在2002年或2003年下一次访问该地点时安装。扫描电镜的未来版本可以根据特定观测站的需要进行修改。
