Logatchev Longterm Hydrothermal Field Environmental Monitoring

该项目的总体目标是在较长一段时间(一年或更长时间)内监测Logatchev热液气田的环境参数(温度、压力、地震活动)，为生物群落的所有长期调查和热液羽流、其来源及其随时间的发展的所有研究提供基本数据集。温度监测工作的重点之一将是评估从裂缝和裂缝中扩散出来的低温外流。此外，还将开发一种探头来测量选定位置的温度并实时传输，以指导ROV的操作决策。所有仪器(水柱剖面记录仪除外)的部署和回收完全取决于是否有深海遥控潜水器或潜水器，这就避免了需要昂贵的释放系统。拟议的技术开发将为SPP 1144的所有成员提供监测其他海底热液油田的基本仪器。

The overall goal of the project is to monitor environmental parameters (temperature, pressure, seismicity) at the Logatchev Hydrothermal Field over a longer period of time (1 year or longer) to provide a basic data set for all long-term investigations of biological communities and for all studies of the hydrothermal plume, its sources and its development over time. One focus of temperature monitoring effort will be to assess the low temperature diffuse outflow from fissures and fractures. In addition a probe will be developed to measure temperatures at selected locations and transmit them in real-time to guide ROV operational decisions. The deployment and recovery of all instruments (with exception of the water column profiling loggers) depends entirely on the availability of a deep sea ROV or submersible, which avoids the need for expensive release systems. The proposed technical development will provide the basic instrumentation for monitoring other submarine hydrothermal fields for all members of the SPP 1144.
