Andrew Seybold: Santa Barbara Amateur Radio Club Helps Chart Ships
in Local
Waters

This screen shot was taken from the
website tracking Automatic Identification System-equipped vessels in
and around the Santa Barbara Channel on a recent Sunday
afternoon.
At any given time there are hundreds of boats and ships in and around
Santa Barbara passenger, cargo, tankers, yachts, U.S. government,
including the Coast Guard, and many
other vessels. Did you know there are two ways of tracking them on
a map? The first is run by the government and this data is not
available to the average boating enthusiast, but the second is an
open-source system that tracks all of these vessels around the
world.
Each tracked vessel has an Automatic Identification System (AIS) device
onboard. The larger commercial and government ships have a type-A device
that sends out data every few seconds while the smaller vessels are
equipped with type-B devices that send out information less frequently.
In the Santa Barbara area there are two stations that track this data.
The first is located at UC Santa
Barbara and the second, which was just installed, is operated by the
Santa Barbara Amateur Radio Club (SBARC).
The nonprofit SBARC also has plans to install two more of these
receivers, one on a mountain site north of Santa Barbara and one on
Santa Cruz Island.
The data that is collected from each of these receivers is sent via the
Internet to a central processing center located in Greece and then
distributed on the web. Click here
to view the data or
click
here to view the local data. You can click on each ship and see
exactly what it is. If there are pictures available they are included,
and you can track where it came from and where it is heading.
Any vessel that is equipped with an AIS device is tracked as long at the
device is on. Depending on the ship, the device might be shut off; for
example, a police boat or Coast Guard vessel, and, of course, panga boats
won’t have operational AIS devices either! Many
marine radios offer built-in AIS and they are very inexpensive. They
are not only used to track the vessels but also for collision avoidance
since boat owners or captains can see other vessels around them even if
they do not have radar onboard.
These sites are also viewed by the Coast Guard and others and are used to
track the vessels, including their speed and if there is a problem with
pollution from the ship. Speed is important because there are limits in
this area to protect whales and other sea animals. Now with a click of a
mouse, the exact speed of all of the ships in the area can be tracked and
any exceeding the recommended speeds can be contacted by radio and warned
to slow down. The last part of the system enables a ship to send out a
distress signal that is then received by the ships around it, and
therefore are close enough to offer assistance.
MarineTraffic.com data is interactive, so users can see exact details of
a vessel’s journey.
Although the government’s system is for its use only, the open-source
system is available to all on the Internet. However, many times
government vessels in these waters will run with their AIS system on to
help prevent collisions, and recently we tracked several
Navy ships and one submarine that had
surfaced and was heading into port. If more boats in this area opt into
AIS (pleasure craft only need type-B AIS equipment), the waters around
Santa Barbara will be even safer for all.
This is only the newest in a series of services being offered by the
Santa Barbara Amateur Radio Club. We already host
a camera on Diablo
Peak on Santa Cruz Island that is used by many pilots and ships that
are heading for the islands. Another camera location is provided to
homeowners in the Mission Canyon
Association; it looks toward the mountains from the SBARC location in
the city.
We also run numerous weather stations that are all connected via the
Internet and are used by the National
Weather Service, paragliders and others. We provide an emergency
communication link between homeowners associations and the
Santa Barbara
County Emergency Operations Center, as well as assist public safety,
the American Red
Cross, Santa Barbara County Chapter and others during major
incidents, parades, marathons and the
Old Spanish Days Fiesta
Parade. And we monitor the local emergency beacon channel that is
used by airplanes as well as boats, and provide direction finding
assistance when an alarm is received at one of our sites.
