Operations Area

US Outer Continental Shelf from VA to FL
Lat/Lon: 30° 0.1′ N / -77° 0.0906′ W
Depth Range: 200 m / 1050 m
Will the vessel be operating within 200 NM of a foreign country? no

Science Objectives

  • Establish an ecosystem observation network that provides baseline monitoring and supports predictive modeling of the soundscape and its relationship to marine life and the environment of the Mid- and South Atlantic Planning Areas.
  • Assess baseline soundscape and ecosystem conditions in support of predictive environmental modeling and trend analyses in the planning areas.
    • How do soundscape and ecosystem components vary with water depth across the OCS?
    • How do the soundscape and ecosystem components vary with latitude along the OCS?
    • Where are the hot spots of human activity for consideration in ecosystem/habitat health impacts?
  • Assess the spatial and temporal distribution of the soundscape and biological scatterers, including their expected variation and correlation with distance from the mooring locations.
    • What are the environmental factors that define and constrain the horizontal range of appropriate extrapolation of observations measured at the stationary mooring sites?

Science Activities

1. Initial deployment of 7 bottom landers.
2. Recovery of first bottom lander on return trip, data download, and re-deployment.
3. Sound propagation experiments (12-18 hours) with ship deployed transducer after bottom lander deployment.
4.  CTD casts in association with each lander deployment and multiple with sound propagation experiment.
5. Zooplankton net tows in conjunction with each lander deployment.
6. Fine-scale acoustic survey transects.
