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.

该项目的总体目标是在较长时间内（1年或更长时间）监测洛加切夫热液区的环境参数（温度、压力、地震活动），为所有生物群落的长期调查和所有热液羽流、其来源及其长期发展的研究提供一套基本数据。温度监测工作的一个重点是评估裂缝和断裂的低温扩散流出。此外，还将开发一个探测器，用于测量选定地点的温度，并实时传输，以指导航天器的操作决策。所有仪器的部署和回收（水柱剖面记录仪除外）完全取决于是否有深海潜水器或潜水器，这就不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场的基本仪器。
