jamming, or spoofng applies equally to the AIS ATONs
as it does to other maritime traffc. This threat reinforces
the continued need for training in position-fxing methods,
using visual and radar information, as well as its ongoing
integration with new electronic navigation aids.
Electronic Marine Safety Information: Analog to Digital
Electronic (or enhanced) marine safety information con-
solidates marine safety information display on the ECS/
ECDIS, which facilitates decision making. Transmitting
marine safety information, such as area notices or ATON
outages, is accomplished in part through an alphanumeric
marine safety information display directly on the display
of the ECS/ECDIS.
Electronic maritime safety information has the potential to
reduce the watchstander's workload by fltering informa-
tion, but it will require a shift from verbal to written (elec-
tronic) forms of communication. Integrating eMSI into the
scanning of bridge equipment displays may allow for height-
ened situational awareness and may ultimately increase the
amount of time spent looking out of the window.
The View From the Bridge
Navigators are taught to "keep ahead of the vessel." New
technology can make it easier to accomplish this objective,
but there must be vigilance to prevent overreliance on or
becoming overloaded with the available information.
The balance between the real and digital world is dynamic.
There will be a shift to greater electronic navigational aids
monitoring, as these same aids provide enhanced informa-
tion and support navigational decision making.
