A complete oceanographic Conductivity-Temperature-Depth (CTD) instrument package, a winged current meter, and two computers equip a new vessel at the consortium. With this new oceanographic vessel, the instruments are used for undergraduate courses in oceanography during summer sessions and weekend field trips. The basic unit in the new instrument package is a CTD logger, which is battery powered and records data in solid-state memory. The CTD measurements provide depth profiles to identify density differences between the surface photic layer and bottom layer in local coastal waters. Biological and chemical variables are measured simultaneously by adding sensors to the CTD for dissolved oxygen, turbidity (by optical backscattering), photosynthetically active light (PAR), and chlorophyll biomass (by in vivo fluorescence). To measure tidal water exchange through Chincoteague Inlet and thus determine fluxes of chlorophyll, nutrients, and zooplankton biomass, the consortium uses a Niskin winged current meter. One laptop computer initializes the CTD instrument package and provides data transfer at sea, and one desktop computer interfaces winged current meter and data analysis. With these instruments, students learn state-of-the-art research techniques to prepare them for graduate school or employment as research technicians. This project enhances the marine science program at the consortium, through which students at inland institutions are able to gain first hand field experiences in oceanography.

一个完整的海洋学电导率-温度-深度（CTD）仪器包，一个翼流速计和两台计算机装备在财团的新船。 有了这艘新的海洋学船，这些仪器在夏季课程和周末实地考察期间用于海洋学本科课程。 新仪器包中的基本单元是CTD记录仪，它由电池供电，并将数据记录在固态存储器中。 CTD测量提供了深度剖面，以确定本地沿海沃茨表面透光层和底层之间的密度差异。 生物和化学变量同时测量通过添加传感器的溶解氧，浊度（通过光学后向散射），光合有效光（PAR），叶绿素生物量（通过体内荧光）的CTD。 为了测量通过钦科蒂格湾的潮汐水交换，从而确定叶绿素、营养物和浮游动物生物量的通量，该财团使用了尼斯金翼式流速计。 一台膝上型计算机安装CTD仪器包并提供海上数据传输，一台台式计算机连接翼式流速仪和数据分析。 有了这些仪器，学生学习国家的最先进的研究技术，为他们准备研究生院或就业为研究技术人员。 该项目加强了该联盟的海洋科学计划，通过该计划，内陆机构的学生能够获得海洋学方面的第一手实地经验。
