A Redesign and Enhancement of the Low Light Auto-Radiometer (LoLAR) for Deep-Sea Irradiance Measurements.

P.I.伊迪丝·威德（海洋研究所港口分支）提案编号：0221097 PI建议升级弱光自动辐射计（LoLAR）。LoLAR是一种水下辐射校准探测器，由NSF和ONR联合资助开发。该仪器目前安装在约翰逊-海联潜水器上，可下潜至1 000米深处，以测量与中层生物垂直分布和迁移模式有关的下沉流辐照度，并对生物发光进行现场测量。LoLAR将光电倍增管的高量子效率与固态自动校准电路相结合。所申请的资金将用于根据经过验证的自动校准概念重新设计LoLAR，利用最新的技术发展，可以大大降低系统的成本、尺寸和复杂性，目的是开发一种多功能仪器，供更广泛的用户使用。

P.I. Widder, Edith (Harbor Branch Oceanographic Inst.) Proposal #: 0221097The PIs propose to upgrade the Low Light Auto-Radiometer (LoLAR). LoLAR is a submersible, radiometrically calibrated detector that was developed with joint funding from NSF and ONR. It is currently deployed on the Johnson- Sea-Link submersible, down to depths of 1000 m to measure downwelling irradiance with respect to the vertical distribution and migration patterns of mesopelagic organisms, as well as to make in situ measurements of bioluminescence. LoLAR combines the high quantum efficiency of a photomultiplier tube with a solid-state autocalibration circuit. The funds requested would be used to redesign LoLAR based on a proven auto-calibration concept, using recent technological developments that make it possible to greatly reduce the cost, size, and complexity of the system with the intent of developing a versatile instrument that can be made accessible to a wider range of users.
