研究了1万吨级深海液体闪烁探测器探测~1 MeV能级电子反中微子的科学潜力。这种仪器设计为便携式，可在深海（3-5公里）中使用，可以对地球地幔放射性衰变产生的反中微子进行独特的测量。这些信息涉及到地质学中一些最基本的问题，如地球的起源、板块构造、地磁场，甚至间接地涉及到全球变暖。多个地点的测量将加强潜在的洞察力。在粒子物理学方面，我们已经确定了一个独特的作用，在研究反中微子从核电厂复杂的，在55-60公里的范围内离海岸。不仅可以精确测量大多数中微子混合参数，包括$\theta_{13}$（取决于大小），而且中微子质量等级可以用一种迄今为止没有讨论过的方法来确定，并且不依赖于物质效应。该探测器正在纸上、实验室和海上进行积极的研究。一个跨学科的国际合作正在形成，一个重大提案的计划正在进行中，随后将在几年内进行建设。
The science potential of a 10 kiloton deep-ocean liquid scintillation detector for ~1 MeV energy scale electron anti-neutrinos has been studied. Such an instrument, designed to be portable and function in the deep ocean (3-5 km) can make unique measurements of the anti-neutrinos from radioactive decays in the Earth'.s mantle. Ths information speaks to some of the most fundamental questions in geology about the origin of the Earth, plat e tectonics, the geomagnetic field and even somewhat indirectly to global warming. Measurements in multiple locations will strengthen the potential insights. On the particle physics side, we have identified a unique role in the study of anti-neutrinos from a nuclear power complex, at a range of 55-60 km off shore. Not only can precision measurements be made of most neutrino mixing parameters, including $\theta_{13}$ (depending on magnitude), but the neutrino mass hierarchy can be determined in a method not heretofore discussed, and one which does not rely upon matter effects. This detector is under active study on paper, in the laboratory, and at sea. An interdisciplinary and international collaboration is in formation, and plans are in motion for a major proposal, to be followed by construction over several years.
