ODP 1027C Digital Optical Module Deployed 2018-06-25

The STRAW Digital Optical Module SN 49-2018-SD1.02 was deployed on 2018-06-25 at ODP 1027C. ODP 1027C is a borehole site used to pinpoint an area within Cascadia Basin. This device is a Digital Optical Module. Digital Optical Modules (DOM) have been a major part of the Strings for Absorption Length in Water (STRAW) project. The DOMs in this project detect light flashes from the Precision Optical Calibration Module (POCAM) as an emitter and and bioluminescence. The optical water properties can be deduced based on the detected light intensity and timing. This device is also used in the Pacific Ocean Neutrino Experiment (P-ONE) project. The components of the DOM in this project consist of photomultiplier tubes, scintillator muon trackers, and various other environmental sensors. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 3.0 digital infrastructure, with quality assurance and derived data products following established practices.

STRAW数字光学模块序列号SN 49-2018-SD1.02于2018年6月25日部署于ODP 1027C站位。ODP 1027C为一钻孔站位，用于精确定位卡斯卡迪亚盆地内的特定区域。该设备为数字光学模块（Digital Optical Module，DOM）。数字光学模块是水中吸收长度阵列（Strings for Absorption Length in Water，缩写STRAW）项目的核心组成部分。本项目中的DOM可探测来自精密光学校准模块（Precision Optical Calibration Module，POCAM，作为发射源）的光脉冲以及生物荧光；可基于探测到的光强与时序信息反演水体光学特性。该设备同时应用于太平洋中微子实验（Pacific Ocean Neutrino Experiment，P-ONE）项目。本项目所用DOM的组成部件包括光电倍增管、闪烁体μ子径迹探测器以及各类环境传感器。该设备部署于固定式平台之上。本次部署产生的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外共享；所有数据均遵循既定规范完成质量管控，并提供衍生数据产品。
