Drifter Resources

Student-built, fishermen-deployed, satellite-tracked “drifters” provide a low-cost means to monitor currents off the New England coast and beyond. These instruments are constructed according to oceanographic standards to move with the current and report their positions on a regular basis. One of the primary motivations for drifter deployments is to help validate circulation models.

Why drifters?  Over the past decade, funding has increased in support of using surface drifters for environmental monitoring that far exceeds the study of surface currents and circulation.  Research using drifters has included investigations into plankton dispersal, movement of harmful algal blooms, oil spills, and tidal power assessments.

Drifters are equipped with a beacon that transmits its location to an end-user via satellite, although other environmental sensors may be attached.  Teachers work with a local boater or fisherman to have the drifter deployed offshore and to retrieve the drifter. Shore-based deployments may also be possible.

Key Concepts:

  • Drifting buoys are part of the Global Ocean Observing System (GOOS).
  • Drifting buoys collect data on sea surface temperature, sea level pressure, and ocean surface current patterns.
  • Knowledge of the ocean surface currents can be used to predict the track of a buoy.
  • Drifting buoys transmit data to satellites, which send them to data collection centers where they can be accessed online.

 

Potential Focus Questions:

  • How are ocean surface currents formed?
  • What are some of the ocean surface currents and where do they flow?
  • What kinds of data can drifting buoys collect?
  • How can we predict the track of a drifting buoy?
  • How can the data from drifting buoys be used?
