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.

Shipboard Communication

Is there a need to receive data from shore on a regular basis?
Is there an expectation to use Skype or any other real-time video conference program?
Basic Internet access via HiSeasNet
Shipboard Communication Notes: There will be a need to receive data from our remote sensing team on shore in conjunction with mooring deployments for high resoultion remote sensing data products.
There will be occassional need of Skype access to participate in conference calls.

Checklist

SSSG Tech:
7 free-fall moorings. Each has a built-in anchor. They have no surface expression, and weigh about 600 kg each. The moorings will be pre-assembled and dropped from the A-frame.

The science compliment will be close to maximum. They will have one person (Carmen) assigned as the mooring tech.

There will be a hand lowered (5-10 meters) transducer (about 75 lbs).
Shipboard instruments required:
EK80 - Yes
Multibeam - Not critical, would like to us it to confirm landing locations
CTD - They have some instruments that they would like to mount to the CTD frame with hose clamps after removing some bottles. The CTD will be used to calibrate the bottom lander.

They have a mid-water net (450 meters) they would like to tow at 1-2 knots using the CTD cable.

Expect about 14 CTD casts interspersed with net tows. Need to have plan to switch wire between blocks.
