摘要

Abstract

Subsurface mooring allows researchers to measure the ocean properties such as water temperature

salinity

and velocity at several depths of the water column for a long period. Traditional subsurface mooring can release data only after recovered

which constrains the usage of the subsurface and deep layer data in the ocean and climate predictions. Recently

we developed a new real-time subsurface mooring (RTSM). Velocity profiles over upper 1 000 m depth and layered data from sensors up to 5 000 m depth can be realtime transmitted to the small surface buoy through underwater acoustic communication and then to the office through Beidou or Iridium satellite. To verify and refine their design and data transmission process

we deployed more than 30 sets of RTSMs in the western Pacific to do a 1-year continuous run during 2016-2018. The continuous running period of RTSM in a 1-year cycle can reach more than 260 days on average

and more than 95% of observed data can be successfully transmitted back to the office. Compared to the widely-used inductive coupling communication

wireless acoustic communication has been shown more applicable to the underwater sensor network with large depth intervals and long transmission distance to the surface.
