Daily Log

What should we do if someone fell overboard or if we had to abandon ship?

Today we are just off the southern coast of Nova Scotia, Canada. It has been foggy all day so we cannot see very far past the ship’s railing. If anyone fell overboard it would be extremely difficult to find them. With the water temperature at 7 degrees C a person would be hypothermic very soon if they were in the water.

I helped Anne again with today’s ozonesonde. The launch did not go as smoothly as yesterday’s. Before releasing the balloon the computer was not receiving a signal from the sonde. After Anne checked out a number of things that could be wrong we attached a different radiosonde, which is the part that sends the signal to the computer. With that change the problem was immediately solved. The sonde detected three layers of ozone pollution and of course the good ozone layer.

The ship’s crew keeps a written record of all ships sighted from the bridge. Today I typed the information into a computer spreadsheet. The scientists will then be able to compare these contacts to their pollution data.

Safety is a major concern on the ship. At school we have fire drills, here on the BROWN we have Abandon Ship and Man Overboard drills. Today when we heard the Abandon Ship alarm (6 short blasts from the whistle followed by one long blast), we rushed to our stateroom (bedroom), grabbed our life jacket, long pants, long sleeve shirt, hat and survival suit. If this were a real emergency we need to have clothes that will protect us from the weather and sun while we are floating in a life raft. We then rushed to our preassigned meeting areas on deck. One of the ship’s crew called roll. Afterwards we practiced putting on our bright red survival suits. The suits are designed to help keep us warm, floating and easy to see.

When the Man Overboard alarm was sounded (three long blasts from the ships whistle) the scientists and myself met in the main science lab to get a head count. Meanwhile as part of the drill, the crew had thrown a “dummy” overboard. They quickly launched one of the small boats and sped away to rescue the “man overboard”. The dummy was rescued quickly. If someone were to fall overboard while the ship is moving and no one realized they were missing, it would be very difficult to find and rescue them since we would not know how far away to look.

Questions of the Day

What is the maximum amount of ozone pollution an area can have without being in violation of the Environmental Protection Agency (EPA) standards?

What is the temperature of the water in degrees F here off the coast of Nova Scotia?

What is the bridge of a ship?

What does hypothermic mean?
