9314259 Webb Webb Research Corporation is a small business that specializes in design and construction of profilers and neutrally buoyant floats for ocean science investigations. The company will design, con- struct, and field test six prototypes of a derivative Autonomous Lagrangian Circulation Explorer (ALACE-B). The primary focus will be the development of a new CO2-based buoyancy generation engine that will be simpler and lighter than previously employed mechan- isms for controlling the drifter's depth. ALACE drifters are neutrally buoyant instruments that drift at a precise pressure gradient within the ocean. They have the capability of carrying a variety of scientific sensors. By changing buoyancy, they can ascend to the surface to telemeter data ashore, then change buoyancy again to sink to their predetermined depth to make more measurements. ALACE-B is designed to operate in the upper 400 meters of the oceans and make up to 200 vertical excursions. Isopyncal drifters, such as ALACE, comprise an important asset to the ocean science research community, and the ALACE-B will provide a new low-cost, upper-ocean capability that meets the scientific requirements of a variety of planned research topics.

9314259韦伯韦伯研究公司是一家小型企业，专门从事海洋科学调查剖面仪和中性浮力浮标的设计和建造。该公司将设计、建造和现场测试6个衍生的自主拉格朗日循环探索者（ALACE-B）原型。主要重点将是开发一种新的基于二氧化碳的浮力产生引擎，该引擎将比以前使用的控制漂浮器深度的机制更简单、更轻。ALACE漂浮器是中性浮力的仪器，在海洋中以精确的压力梯度漂移。它们有能力携带各种科学传感器。通过改变浮力，他们可以上升到水面，在岸上遥测数据，然后再次改变浮力，下沉到预定的深度，进行更多的测量。ALACE-B的设计目的是在400米以上的海洋中工作，并进行200次垂直航行。ALACE等径漂移船是海洋科学研究界的一项重要资产，ALACE- b将提供一种新的低成本的上层海洋能力，满足各种计划研究课题的科学要求。
