0321167 Checkley0320739 JacksonThis collaborative Major Research Instrumentation award to Scripps Institution of Oceanography (University of California at San Diego) and Texas A&M University provides funds for development of the SOLOPC, an autonomous profiling float that combines existing SOLO float profiler technology with a laser optic plankton counter (LOPC) to provide a means of assessing oceanic zooplankton distribution in addition to physical ocean properties and circulation. The initial objective is to develop an instrument that will produce 50-100 profiles over a period up to one year, during which it will transmit position and profile data via satellite when at the surface, and ultimately be recovered. The longer-term objective is to develop relatively inexpensive, expendable instruments, suitable for ocean basin-scale studies. The development effort builds on several generations of profiling floats, including ALACE and SOLO, which profile, drift and transmit physical oceanographic and position data via satellites to autonomously profile currents and physical properties of the ocean. The additional data here on zooplankton size with the LOPC will be augmented with a fluorometer for measuring chlorophyll a as well. Field evaluation and testing is incorporated in the three-year development effort in several ways. Initial evaluation of float parameters will be tested offshore from Scripps Institution in small boats. More complete testing will involve 20 days of UNOLS vessel time (Sproul, New Horizon), validating SOLOPC data against shipboard data collected with water samples and net tows, and the final testing will include deployment during a CALCOFI cruise off Southern California, with the floats transiting the standard grid of Southern California stations simultaneously with the research vessel. This instrumentation award is supported by the Division of Ocean Sciences at NSF. Scripps Institution of Oceanography provides cost sharing support from non-federal funds.***

0321167 Checkley0320739 Jackson 这项合作重大研究仪器奖授予斯克里普斯海洋学研究所（加州大学圣地亚哥分校）和德克萨斯 A&M 大学，为 SOLOPC 的开发提供资金，SOLOPC 是一种自主剖面浮标，它将现有的 SOLO 浮游生物剖面仪技术与激光光学浮游生物计数器 (LOPC) 相结合，除了物理测量之外，还提供了一种评估海洋浮游动物分布的方法。 海洋特性和环流。最初的目标是开发一种仪器，能够在长达一年的时间内生成 50-100 个剖面图，在此期间，它将在地面时通过卫星传输位置和剖面数据，并最终被恢复。 长期目标是开发相对便宜、适用于海洋盆地规模研究的一次性仪器。 这项开发工作建立在几代剖面浮标的基础上，包括 ALACE 和 SOLO，它们通过卫星进行剖面、漂移和传输物理海洋学和位置数据，以自动剖面分析海流和海洋的物理特性。 LOPC 中有关浮游动物大小的附加数据也将通过用于测量叶绿素 a 的荧光计得到增强。 现场评估和测试以多种方式纳入三年的开发工作中。 浮标参数的初步评估将在斯克里普斯研究所的海上小船上进行测试。 更完整的测试将包括 20 天的 UNOLS 船时间（Sproul、New Horizo​​n），根据水样和网拖收集的船上数据验证 SOLOPC 数据，最终测试将包括在南加州附近的 CALCOFI 巡航期间进行部署，浮标与研究船同时通过南加州站的标准网格。 该仪器奖由美国国家科学基金会海洋科学部支持。 斯克里普斯海洋学研究所提供非联邦基金的成本分摊支持。***
