The second of these methods is called a cluster release. Basically, we just put all the drifters over the side at the same time and in the same location. This type of deployment is similar to a sudden release from a location.
The map displayed here is an example of a cluster release. The drifters were deployed at 10:08AM at the mouth of the Lubec Narrows. It is interesting to note how they dispersed and moved at varying speeds. Some ended up in Johnson Bay, others hung out in an eddy off Rodgers Island before moving into Cobscook Bay.
