Bottom Observatory Small Experiment Module

申请资金用于设计、建造和测试用于海底观测站的小型实验模块（SEM）。该模块的目的是减少在海底进行相对简单的观测实验所需的努力。海底观测站将很快为调查人员提供机会，利用观测站的电力进行科学调查，并通过观测站将数据传输到岸上。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、滤波、数字化、定时、电源和数据格式，以及复杂电子设备、压力容器、浮力装置和相关硬件的构造。拟议的模块将大大简化这项任务，使研究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，但安装相对简单的实验与SEM相结合将远不那么复杂，使许多人更容易参与天文台科学，成本效益更高。我们设想在几乎每个主要海底观测站的科学节点上都有一个类似于SEM的包。这里提出的原型应该指出我们对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连接多达12个传感器的端口，其中包括用于海啸探测的绝对压力传感器。据建议，夏威夷2号天文台的第一台扫描电镜将在2002年或2003年下次访问该地点时安装。未来版本的扫描电镜可以修改，以满足特定天文台的需要。

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.
