This award provides one-half the funding necessary to support a major equipment acquisition at the Woods Hole Oceanographic Institution (WHOI). WHOI is committed to providing the remaining funds needed for the acquisition of a large-radius, high- transmission, secondary ion source mass spectrometer system, more commonly referred to as an ion microprobe. Recent technological developments have made the new generation ion probes capable of measuring isotopic species with extremely high abundance sensitivity and micron-level spatial resolution in samples of geological interest. The WHOI ion microprobe will be installed and maintained at the Woods Hole campus and operated as a facility open to the national geoscience research community. The analytical capabilities of the new instrument will be employed in research areas including the early evolution of the Earth, upper mantle dynamics (melting, melt extraction, generation of basalts), deep-seated metamorphic processes (rock-fluid physicochemical interactions), and environmental geochemistry (use of oxygen isotopes and trace metal distribution in foraminifera and bivalve shells to monitor changes in temperature and nutrient content of seawater).

该奖项提供了支持伍兹霍尔海洋研究所（WHOI）主要设备采购所需资金的一半。WHOI致力于提供所需的剩余资金，用于购买大半径，高透射，二次离子源质谱仪系统，更通常被称为离子微探针。最近的技术发展使新一代离子探针能够在地质样品中以极高的丰度灵敏度和微米级的空间分辨率测量同位素。WHOI离子微探针将在伍兹霍尔校园安装和维护，并作为向国家地球科学研究界开放的设施运行。新仪器的分析能力将用于研究领域，包括地球的早期演化、上地幔动力学（熔融、熔体提取、玄武岩的产生）、深层变质过程（岩石-流体物理化学相互作用）、环境地球化学（利用有孔虫和双壳类动物壳中的氧同位素和痕量金属分布来监测海水温度和营养成分的变化）。
