Science Objectives

ADEON is generating long-term measurements of both the natural and human factors active in the mid-south Atlantic Outer Continental Shelf (OCS) region, thus informing the ecology and soundscape of the OCS.  These data will provide further a mechanistic understanding of the cumulative impacts these factors have on marine resources and provide insight for ecosystem-based management efforts.  Long-term observations of living marine resources and marine sound will assist Federal agencies, including BOEM, ONR, and NOAA, in complying with mandates in the Endangered Species Act (ESA), Marine Mammal Protection Act (MMPA), and Sustainable Fisheries Act (SFA).

  • 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.
  • Develop standardized measurement and processing methods and visualization metrics for comparing ADEON observations with data from other monitoring networks.
  • 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 bottom-lander locations.
    • What are the environmental factors that define and constrain the horizontal range of appropriate extrapolation of observations measured at the stationary bottom-lander sites?

Science Activities

This expedition is the last of five cruises for the ADEON project focused on recovering 7 bottom landers at six sites along the outer continental shelf (OCS) of the United States east coast.  In addition to the lander work, station sampling will occur at each location consisting of CTD profiles, net trawls for biological specimens, and a fine-scale, lawnmower pattern active acoustic survey. At the ADEON JAX site, Jason operations will be conducted to recover an ADEON lander that was not recovered during the AR040 cruise in 2019. Jason engineering dives will also be conducted for 2 days mid-cruise.
Itemized tasks are as follows:
1. Recover 6 ADEON landers by acoustic release
2. Recover 1 ADEON lander at JAX with ROV Jason
3. Conduct 2 ROV Jason engineering dives
4. Deploy 3 landers at HAT, WIL, and SAV
5. Conduct CTD casts at 6 ADEON sites
6. Conduct zooplankton net tows and fine-scale acoustic survey transects at 5-6 ADEON sites
