Mission: 2009 United States/Canada Pacific Hake Acoustic Survey
Geographical area of cruise: North Pacific Ocean from Monterey, CA to British Columbia, CA.
Date: July 29, 2009
Weather Data from the Bridge (0800)
Wind speed: 10 knots
Wind direction: 345° from the north
Temperature: 14.1°C (dry bulb); 13.8°C (wet bulb)
Sea water temperature: 10.6°C
Wave height: 1 ft.
Swell direction: 320°
Swell height: 3-5 ft.
Air pressure: 1011.0 mb
Weather note: There are two temperature readings taken on the Miller Freeman. The dry bulb measures the current temperature of the air. The wet bulb measures the absolute humidity of the air; uses a thermometer wrapped in a wet cloth. The dry and wet temperatures together give the dew point and help to determine humidity.
Science and Technology Log
Those aboard the Miller Freeman: including NOAA Corps, crew, and scientists were randomly selected to answer the following question.
How are science and the environment important to the work you do?
Here are some of their responses:
The engineers aboard the Miller Freeman are a group of hard working people. There are always engineers on duty 24 hours/ day to ensure the ship is running properly. Jake DeMello, 2nd engineer, gave me a tour of the Miller Freeman’s engine room. Jake attended California Maritime Academy where he received his Bachelor of Science degree in Marine Engineering. He has a 12-4 shift which means that he works from noon to 4:00 p.m. and then again from midnight to 4:00 a.m.
Before taking the job aboard NOAA’s Miller Freeman, Jake worked on a Mississippi River paddle boat traveling from New Orleans north past St. Louis through the rivers’ many dams and locks. He reminisced on one memorable moment aboard the paddleboat; the day he saw Jimmy Dean, the famous singer and sausage maker. Jake and the other engineers do many jobs around the ship including checking the fuel and water levels throughout the day and fixing anything that needs repairing. The Miller Freeman is equipped with a machine shop, including lathe and welding equipment.
Among the jobs of the engineer is reporting daily fuel levels including:
- Hydraulic oil used for daily fish trawls, CTD, gantry, and winch operations.
- Gasoline used for the “Fast Recovery Boat.”
- Diesel fuel used for the main engine.
- Lube oil used for main engines and generators.
Fresh water production: The ship’s water desalination machine transforms 2,000 gallons of sea water into fresh drinking water daily. The ship’s water tanks hold a total of 7,350 gallons of fresh water. Another job of the engineer is taking soundings throughout the day/night. Taking soundings means measuring the levels of liquid in the tanks. There are tanks on both the starboard and port sides of the ship. The engineer needs to be sure that fuel levels are evenly distributed so that the ship will be evenly balanced in the ocean.
Vocabulary: Starboard: right side of the ship. Port: left side of the ship.
I write this off the coast of Oregon in the North Pacific Ocean. It has been an amazing 17 days aboard the Miller Freeman. I feel honored to have participated in NOAA’s Teacher at Sea program. It has truly changed the way I look at science in the classroom and has given be a better understanding of how scientists conduct research on a day to day basis in the field. I am excited to have made so many learning connections between the real world of scientific study and the elementary school science classroom. I thank NOAA, the Teacher at Sea program and the entire crew, NOAA Corps, and scientists aboard the Miller Freeman for this opportunity.
