Virtual Tour of the Oregon II
I know many of you may have never been on a ship before and are probably curious to know what it is like to be aboard the Oregon II. I’m going to take you on a little virtual tour, but first you will need to know some common terms that are used to refer to certain areas on the ship.
What It Means
|Bow||The front of the ship.|
|Stern||The back of the ship.|
|Starboard||The right side of the ship when facing the bow.|
|Port||The left side of the ship when facing the bow.|
|Forward||The direction towards the bow of the ship.|
|Aft||The direction towards the stern of the ship.|
|Bridge||The location of the command center for the ship.|
|Mess Hall||The dining area.|
|Stateroom||Where crew members sleep.|
At the bow of the ship is where most of the scientific collection equipment is deployed/released. The CTD (conductivity, temperature, depth), the neuston net, and the bongo nets. (I will talk about each one of these in upcoming blogs.) There are several large cranes that help lift these up off the deck and swing them over the edge of the ship to be released into the water. When you are at the bow and the cranes are running, it is very important to keep yourself safe. Everyone who is at the bow when the cranes are operating is required to wear a hard hat and a PFD (personal floatation device). You never know if a cable will snap or the wind will swing the equipment towards you. There is a sensor on the PFD that is activated when large amounts of saltwater touches it, like if you were to fall overboard. Once salt water touches the sensor, the PFD will inflate and keep you afloat until you can be rescued.
At the stern is where the samples from the neuston cod end and the bongo cod ends are collected and preserved in jars for scientists to examine at a lab. This is also where the large trawling net is deployed. The scientists spend most of their time at this part of the ship.
What Makes the Ship Sail?
The bridge is where the officers of the Oregon II work. It is located toward the bow of the ship. The bridge has all of the navigation tools necessary to steer the ship to the next sampling station. There is also a lot of weather equipment that is monitored and recorded throughout the day. The bridge is where you’ll find the best views of the ocean because it is almost completely surrounded by windows and it’s higher than any other room on the ship.
This room is where all of the maps are stored. While there are more technologically advanced methods used for navigation on the ship located in the bridge, it is important to have physical maps on hand to refer to, especially if the instruments stop working for any reason.
Before we untied our ship from the dock I received a full tour of the engine room. This is where the heart of the ship is. Everything in the engine room powers the ship. Our water is even purified down here using reverse osmosis (passing water through a membrane to filter the water). Because of this machine, we can filter salt water into fresh water to use on the ship.
It was great to venture down to the engine room before we set sail because I was told that it can get up to 110 degrees when the engines are running! It is a large space, but it feels small because of the large equipment. There are two of everything, which is especially important if something needs repair. Below is a picture of the two engines. The other is a picture of one of the generators.
Living on a Ship
My stateroom is compact, but its main purpose is for sleeping so size isn’t really an issue. There is a bunk bed, a sink with a mirror, latching drawers for clothes, and a hide-away desk. There is also a compact tv that is attached to the bottom of the top bunk and folds up when it is not in use. I only use the room to sleep and get ready for my shift because my bunkmate works the opposite watch shift as mine (midnight to noon), and I want to be the least disruptive as possible. After 12 hours shifts, sleep is really needed and helps reenergize you in time for the next watch.
The head is the same as a bathroom. On the Oregon II there are private and communal heads. The private heads are for the officers and are typically connected to their staterooms. The communal heads are open for any crew member to use. There are also communal showers for the crew to use. All of the toilets use salt water that is pumped onboard. The reason fresh water is not used is because it is a precious source on the ship and is not readily available from the ship’s surroundings. The sinks, showers, drinking fountains, and ice machines all use fresh water. Fresh water on the ship should never be wasted. Water for the sinks is timed so that there will never be a faucet that is accidentally left on. Showers are to be kept to a maximum of 10 minutes, though it is encouraged that they be even shorter.
Galley and Mess Hall
This is one of my favorite places. The galley is where our ship’s cooks prepare all of the wonderful food for the crew. The mess hall is where we all eat during meal times. During meal times it can be quite crowded in the mess hall as there are only 12 available seats and over 30 crew members onboard who are ready to eat. There is an “eat it and beat it” policy to help ensure that everyone who comes down to eat will be able to find a spot. Despite this, it is still a great way to converse with the crew and talk about events from the day before giving up your set to another hungry crew member.
This is the place where crew members who have some down time can gather and socialize, though down time can be rare. There is satellite tv, a couple of computers, and hundreds of movies to choose from. Some available movies haven’t even been released onto DVD for the common household yet, but they are available to the military. They do this because not everyone has access to current movies when they are away from home for extended periods of time. All of the DVDs are encrypted and can ONLY work on the machines aboard the ship. I was excited to find a copy of The Hunger Games and I plan on trying to watch it before my trip is over.
Labs on the Oregon II
The Wet Lab
The Wet Lab is where all of the samples from the groundfish trawls are sorted, counted, measured, weighed, and sexed (gender identified). Buckets filled with animals from the nets are dumped onto a large conveyor belt and spread out to make sorting the different species out into individual baskets easier. Everything in the wet lab can get wet except the sensors connected to the machines. We need to be cautious around the sensors when we are cleaning up after a sampling so as not to get water in them.
The Dry Lab
The Dry Lab is where all of the computers are located that record all of the data from the samplings. As the name of this lab states, everything in it is dry. Water should never come into contact with the equipment in here because it can seriously damage it. In between samplings, this is typically where the scientists gather to wait for arrival at the next sampling station.
The Chem Lab
This is where all of the plankton samples are stored. It is also where water samples taken from the CTD are tested for dissolved oxygen (DO). The CTD does have its own DO sensor, but it is always best to test something more than once to ensure you are collecting accurate data.
When I woke up the next morning, I decided to venture out into downtown Pascagoula which was only a 5 minute walk away from the ship. It is a quaint area with little shops and restaurants. I met up with the two volunteers and we picked a business that had the best of both worlds, a restaurant and a shop, to have a wonderful breakfast. We had to be back on the ship by 12:30 for a welcome meeting, but we took some time to snap a few pictures of our floating home for the next 12 days. We were underway shortly after 2 pm (1400 hours in military time). It was fun to watch our ship depart from the dock and enjoy the light breeze. It wasn’t long until we had another meeting, this time with the deck crew. We learned about the safety rules of working on deck and discussed its importance. The rest of the afternoon was spent relaxing and getting my sea legs. The gentle rocking does require you to step carefully, especially when you have to step through the water tight doors!
Right after lunch I got to jump right in and help finish bagging, labeling, and cleaning up the wet lab for the team that was just finishing up their shift. After we had finished it was time to conduct my first plankton sampling. We went out on deck at the bow of the ship to prepare the CTD (conductivity, temperature, depth) device for deployment/release. After the CTD was released and brought back on deck, we deployed the neuston net to collect species samples from that same station. (I’ll explain the importance of this type of net in a later blog.) Once the collection time was complete, the neuston net was brought back on deck where we detached the cod end and placed it into a large bucket. Cod ends are plastic cylindrical attachments with screened holes to let water run through but keep living things inside during collection. The neuston cod end’s screens have 0.947mm sized openings. We then deployed the bongo nets to collect samples of even smaller species like plankton. (I will describe the purpose of the bongo nets in a later blog.) When the nets were brought back on deck, we detached the cod ends from the two bongo nets and placed those into buckets as well. The screens on the cod ends for the bongo net are even smaller than the neuston’s at only 0.333mm. When all of the nets were rinsed to make sure nothing was still stuck to the inside of the nets, we brought the buckets back to the stern of the ship to further rinse the samples and place them into jars for further examination by scientists.
