We Will Learn
1. Why universal communication on the high seas is
important;
2. How the U.S. Integrated Ocean Observing System (IOOS)
supports safe and efficient maritime operations; and
3. The International Code of Signals (ICS).

Intro to International Code of Signals
-
International Code of Signals
First Code of Signals developed in 1850’s
Current International Code of Signals revised in 1965
• Safety of navigation and persons• Can be communicated visually
(flags), radio (alphabet),
radiotelegraph and horns (morse code) • Each letter of the ICS
alphabet also has a name and flag to
represent the signal

Clear and precise communication is essential to safe navigation
on high seas and in and out of ports. Safe navigation protects
people, environment, and cargo.
For example, if one of these ships was experiencing engine
failure in this densely packed shipping lane, they may communicate:
Foxtrot, Delta, Kilo, Victor to other ships nearby. They could
repeat those ICS letters over their radio, and/or fly these flags
Indicating that they are disabled (Foxtrot), keep clear (Delta),
they would like to communicate (Kilo), and they require assistance
(Victor).

What will we do?1. Practice decoding a word given to you
in International Code of Signals format. You will use the ICS
guide to determine each of the five letters.
2. Create a class banner using ICS symbols. For the activity,
your class will come up with a saying for the banner. Each student
will need:
• White paper or cardstock (about 6x6”)• Crayons, colored
pencils or markers
(red, black, yellow and blue, depending on the symbol
assigned).

Now let us make a class banner!1. Select a saying for the class
banner
• Same number of letters and/or numbers as the number of
students
• Ideas include: School mascot, Go science!, etc.
2. Assign a letter for each student to color
3. Then color the letter!
4. String banner and hang in classroom
