Science and Technology Log

While I have been at sea,  I have spent time exploring Pisces and getting to know the people on board. This research vessel is 209 feet long, 50 feet wide, and it has a draft of 20 feet.  It is large enough to hold 39 passengers. The crew of the vessel during my sail consists of 5 NOAA Officers, 5 deck crew, 5 engineers, 4 technicians, 2 stewards and 5 scientists.

NOAA Ship Pisces

NOAA Ship Pisces

Pisces is loaded with science equipment. It has the capability to run acoustic surveys, marine mammal surveys, and various fish surveys. The onboard wet lab is used to process the marine life brought in on trawls, long lines, or bandit reels. In the dry lab, the mission data is stored and processed by the scientists and survey technicians on the ship.  There is a side sample station on the starboard deck where the cameras and ROVs are launched and the trawls are deployed on its stern. The centerboard, on the hull underneath the ship, has mounted sensors that send back various types of data for the scientist to use. This vessel was also engineered to be quiet while underway so it won’t scare marine life. The ship shares the oceanographic, hydrographic and weather data it gathers daily to the outside world.

The Commanding Officer gave me a tour of the bridge.  The bridge is the navigation center. The vessel can be operated from one of four different stations. The science that is being conducted determines where the officer will navigate from. The technology on the bridge is quite amazing.  The dynamic positioning system allows the vessel to stay within certain parameters when supporting science missions. It functions almost like an auto-pilot to keep the ship in the proper position.

"Moo"ving the ship

“Moo”ving the ship

 

NOAA Ship Pisces is like a floating city.   I had the opportunity to explore the engine room with the ship’s first assistant engineer to see how this mini-city works.  He showed me how they process sewage and garbage aboard the vessel. I learned how the vessel creates its own water and power.  I saw the huge engines. This ship has two 8 cylinder engines and two 12 cylinders engines that power the ship. I also learned how the bilge/ballast system keeps the ship stable and how the bow thruster aids in steering

Personal Log

Most of the days pass quickly and I lose track of time.  I can’t believe I have been at sea for 10 days. Having a different type of workday is very unusual to me.  I have taught for almost 18 years so school days are what I know. It is different to work with adults all day instead of children.  It is a definite change of pace. Today is a slow day. We are currently standing-by due to a weather delay. We have moved closer to shore and are riding out the storm.  Hopefully, we will be able to be back up and running tomorrow.

I will surely miss the trips to the galley when I get home. I have probably gained five pounds on this trip. The stewards that cook on this ship do an amazing job.  It is nice to have already prepared meals. I have gotten spoiled by not cooking too. I know will miss the view when I get back to land. Watching the waves never gets old.  I could stare at the water all day. Even when it is stormy the ocean is beautiful.

Being away from home is hard.  It’s difficult not to harass my team teachers about my classroom while I am gone.  I know that my students are well taken care of but it is hard not to worry. The letters from my students, emails from family,  texts from my husband, messages from friends, and sweet videos from my granddaughter help me combat homesickness.

Did You Know?

The Gulf of Mexico is home to 21 marine mammals and 5 sea turtle species

Student questions

How many species of sharks are in the gulf?  There are approximately 49 shark species in the gulf.
