Science and Technology Log 

Earlier this week I went out on launch RA 6 to run some lines off Biorka Island.  The weather was a little dreary and cold but made much warmer by the crew, which consisted of Chief Boatswain Steve Foye, AB (Able Body Seaman) Leslie Abramson, and LTJG (Lieutenant Junior Grade) Nicola Samuelson.

Seas were a little rough running between 4 and 6-foot swells, but the crew did an excellent job staying on their lines and completing the task assigned. Conditions are not always ideal, yet the job must still be done.  If seas are too rough the crew will head to a bay or protected area that still needs to be worked.  Steering a boat in rough sea conditions isn’t easy.  Chief Foye was on board to assist AB Abramson if needed.  Leslie did an excellent job controlling the boat while down below LTJG Samuelson was collecting the data from the sonar.  LTJG Samuelson has finished her 2-year assignment with the RAINIER and will be heading to Rhode Island for her next duty station when we reach our next port stop of Juneau.

Personal Log 

This day was an interesting one. I learned when you feel nausea or seasickness it is better to eat something even though you don’t fell like doing so at the time.  I really enjoyed learning so much about the day-to-day data collection techniques used by the crew of the RAINIER. The equipment is quite sophisticated and the people using it are very well trained. LTJG Samuelson was very helpful in explaining how the data is collected, stored, retrieved, and used to make the nautical navigation charts that NOAA publishes.  The boatswain crews are well trained and do a good job piloting the launch boats through strong tide currents, rocky coastlines, and even rough seas.

Questions of the Day 

How deep is a fathom?

When a ship anchors there are red, white, and blue chain links to show how deep the anchor is. What is the length between these colors called?

How long is this length of chain?

How much does one anchor on the RAINIER weigh?

How much does one marked length of chain weigh on the RAINIER?

What is the keel of a ship?

What is meant when people are talking about a ship or boats draft?

What does it mean when a ships bell rings continuously for 5-6 seconds every minute when it is anchored in open water?

Thanks to Ordinary Seaman Megan Guberski for helping me to pose and answer some of these questions.
