An OBS Capable of One Year Deployments

伍兹霍尔海洋研究所(WHOI)将承担一项工程开发和测试计划，以升级一套海底地震仪(OBS)，部署长达一年。已向海洋科学界提供了大约30个开放式海洋观测系统。世界卫生组织在东海岸保留了一半的仪器，在西海岸的斯克里普斯维护了同样数量的仪器。这套仪器被设计成具有共同的能力和响应特征，并采用了模块化设计，因此各种组件可以很容易地升级。标准的电池组和数据记录器只允许部署两个月。科学要求越来越需要更长的部署时间，最长可达一年。其中两个标准OBS将改装新的电池组和防腐措施。其中一支部队将在海外部署一年，但会定期检查。这一开发和测试计划的结果将与使用该仪器的其他机构共享。

The Woods Hole Oceanographic Institution (WHOI) will undertake an engineering development and testing program to upgrade a suite of Ocean Bottom Seismometers (OBS') for deployments of up to one year. Approximately thirty OBS' have been made available to the ocean science community. Half of the instruments are maintained on the East Coast at WHOI, and an equal number on the West Coast at Scripps. The suite of instruments were designed to have common capabilities and response characteristics, and modular design was use2d so various components could be readily upgraded. The standard battery packs and data loggers allow for deployments of only two months. Scientific requirements increasingly call for longer deployments, lasting up to one year. Two of the standard OBS' will be converted with new battery packs and corrosion preventative measures. One of the units will be deployed offshore for a year, but checked on a regular basis. Results of this development and testing program will be shared with other institutions that use the instruments.
