Science Log

What an exciting day! The first time we launched the ROV (Remote Operated Vehicle) into the ocean at our first MPA (Marine Protected Area) in North Florida. The amount of manpower and communication that goes into something like this is just extraordinary. The deckhands must be available and working with the crane to gradually place the ROV into the water, the crew must be on the bridge communicating with the scientists and the deckhands to maneuver the ship where needed, and finally the scientists have to be working gathering data and making sure the ROV is placed where the MPA site is located. Even before the ROV is launched something called a CTD (Conductivity Temperature and Depth) is lowered into the ocean to gather water temperature, salinity, and depth. This CTD device is lowered twice in one day, once at the beginning of the day and once at the end of the day to give the scientists some raw data of the waters.

The ROV will usually “dive” for about an hour while the scientists record live footage. One scientist is actually driving the ROV from inside the ship. The ROV has four propellers that run from an electric motor supplied by the electricity source provided by the ship. It almost looks like he’s playing a video game when he is driving. It’s got two joysticks and a monitor that he follows.

Another job is where a scientist is keeping track of the 37″ TV monitor. He or she records the species of fish seen along with longitude, latitude, depth, and floor surface. Yet another scientist is working taking still and video photographs from the ROV while providing audio narration to aid in video analysis when reviewing back in the lab.

All the above is going on and still don’t forget the communication between the bridge and the scientists. If the scientists want to move the ship just about 400m due East then he will radio up to the captain on the bridge and the ship will move 400 m due East being very careful not to run over the ROV or cause any other safety concerns. Safety is NOAA’s biggest concern!

Take a look at the animals I have seen today:

Amberjack fish
Red snapper fish
Yellow tail snapper fish
Lion fish
Toad fish
Hog fish
Shark
Ramora fish
Reef butterfly fish
Soldier fish
Black coral
Goliath grouper!!!
Scamp fish
Moray eel
Sea turtle
Barracuda fish

Look these up and send me a photo….. I’ll let you know if that’s what I see!

Science Log

We sailed last night to our first “station” – The North Florida Marine Protected Area – and by 7:00 am this morning the ROV pilots Lance Brown and Glenn Taylor were going through the “pre-flight” checklist on the ROV; Lance working the controls in the lab, Glenn outside taking care of the deployment and extraction of the vehicle on the starboard weather deck. Soon they were meeting with the Lead NOAA scientist Andy David to talk through the operations of the deployment and extraction and more specifically the methodology of what they were trying to accomplish at this site.

The North Florida MPA area has been protected since 2004 – meaning no sailing or fishing occurs in this area. Some of the area has been mapped by multi-beam sonar – so what scientist then do with ROV technology is “Ground-Truthing” in which after examining the multi-beam maps – choose features to explore and check visually how they compare with their maps. Since the ROV sends real time video feed to the lab, the scientist watch and note the features, the animals that are present or not present in the habitat. They also perform a down shot every 2 minutes, or stop the ROV – point the camera down and take a picture – later in the lab they quantify the habitat by gridding the photograph and counting the number of species. Todays North Florida site tested sites inside the Marine Protected Area as well as sites/features outside the MPA for comparison as well as to help make future decisions of extending possible areas into the protective zone or even species.

After the scientists met, the Pisces crew and captain Jeremy Adams met on the weather deck to talk through the operation – sync their communications and what if scenarios. In all, there were 3 ROV dives which went extremely smooth, mainly due to the organization and communication of everyone involved.

The highlights of the dive were the spectacular features of the exposed limestone near the drop offs and the amazing habitats – for all my preparation the diversity of fish was overwhelming – I could identify a few featured fish like the Lionfish, barracudas and Moray Eels – I was unprepared to see a real sea turtle hanging out by some rocks or a Goliath Grouper which came out of nowhere. I learned many new fish which I hope to be able to call out from the monitor tomorrow like the Reef Butterfly, Squirrel Fish, Amberjack, Scamp, Soldier fish, Purple and Yellow Tail Reef Fish. I was helpful in identifying some of the Occulina deep coral species, the sponges (which you couldn’t miss) as well as pick out old fish line, a bottle and and an old anchor jammed into the rocks near the edge.

I’ll let the pictures and video slices tell most of the story. We are cruising all night again to our most northern site Edisto – off South Carolina and then work back from there.

Today we were ported in Jacksonville, FL. It was load up and set up day for the additional scientists and the ROV (Remote Operated Vehicle).

The ROV is similar to a traveling robot that will be lowered down onto the ocean floor and will be remotely operated from the ship while recording ocean life at each MPA (Marine Protected Area) that we visit. Since PISCES is a brand new ship she wasn’t equipped for all the hardware and software needed for the ROV; therefore, all the engineers, deckhands, scientists, and crew were involved in a speedy setup. The scientists also loaded a fish trap just in case we need extra data in addition to the ROV.

We set off to our first MPA in North Florida to do our first ROV trial testing in the morning to get some live data. I am so anxious to see how the ROV works and what sort of data we will receive. I know I will sleep well tonight because I was working right along side everyone. Remember all those measurements I have you take and then convert them from English to metric units? That’s what I had to do today. We had to measure how far the equipment was in respect to the size of the ship, etc. You want to know how you will use what you learn in ‘real life’? Well, here it is!

I did see a dolphin today, but too quick for a pic! SRRY 🙂

Also, I was able to watch the launch of the space shuttle Atlantis.

Science Log

We arrived late last night back in Jacksonville, Florida docking at the Atlantic Marine Docks – taking on 8 scientists who will leading the ROV operations – over the next few days. The next morning was a flurry of activity as the science crew began to unload their equipment and the crew of the Pisces operated the cranes and prepared the the sides of the ship and the winches for deployment of the ROV.

While Jeannine stayed aboard to help running cables and rigging the GPS equipment needed for pinpointing the position of the ROV relative to the ship – I chose to join the scouting party inland; myself, Lieutenant Dunsford, Engineer Tony Assouad and Lead Scientist Andy David made contact with local at the village of “Walmart” and acquired much needed supplies.

Gear was stowed and the equipment set up, the science party met for their safety briefing, followed by a larger conversation of what we will be accomplishing over the next couple of days. We plan to take the “Deep Ocean ROV” to at 3 sites – testing in and outside the MPA or “Marine Protected Area” about sites a day. We will be running mostly day time operations and transitioning to next station at night as well as doing some multibeam mapping – using the same type of technology I mentioned in yesterday’s blog. When the Pisces arrives in an area it will begin to “mow the lawn” – doing transects back and forth to create a map of the ocean floor below so the scientists can better choose targets or areas to avoid during the daytime ROV operation. For the most part we are assisting the scientists with the launching and retrieval of the ROV as well as monitoring what the ROV sees from a TV in the Dry Lab on the Pisces.

Like a lot of science the ROV will be recording a ton of data which will be more carefully evaluated over the next few months after the voyage. Many of the places we document in and out of the MPA will be explored again to see changes – so in a way this study sets a baseline for future missions. I am excited to see how they launch the ROV, which will give me some ideas for when my Innovation Technology Seminar launches their little rovers in a few weeks. The operator/pilot of the rover will be inside the dry lab talking through a headset to another rover scientist outside monitoring the 900 feet of cable – talking to a deck crew member operating a winch. We are hoping not only for calm waters on the surface for deployment-but quiet currents below so ROV has the opportunity to explore, rather than ride the current.

A few porpoises rolled along side the ship enough to enjoy, but too quick to get a good picture. Only the gray pelicans on the dock would stand still to pose. Before we pulled out of Jacksonville we climbed to the top of the Flying Deck to watch the Space Shuttle Atlantis launch in the distance. Even though we didn’t do much today it was still a pretty great day. 🙂

Science Log

Of the many things I have learned so far there are three things that are standing out in my mind right now that I can share…..1) there is so much ionization in the ocean (salinity) that if it’s not neutralized it can cause many rusting/electrical problems on the ship 2) water on the ship is purified by passing through a UV light before it is sent for drinking and using on the ship 3) plank owners are called the very first crew members on a new ship!

When I went on the tour of the engine room or should I say rooms. The engineer pointed to a sign that read “cathode”. Well, I know my physical science students remember that a cathode is an electrode where an electric current flows out of a polarized electrical device. Anyway, the ship has all this salt water flowing in (lots of NACL) that has an electric charge so it has to be neutralized using the cathode so the water doesn’t cause any high electrical charges that can be dangerous with so much high voltage already running on the ship. Cool, huh?

Then the engineer explained the process of making water. The ship goes through about 1800 gallons of water per day. Through the process of purifying the water at the final stage is a tiny box with a long rectangular tin attached to a long thick wire. Above this box water flows through another tube flowing across the rectangular box. It reads ‘CAUTION: UV radition light’. As the water flows across the UV light it is emitting short wavelengths of ionizing radiation to rid of any living microorganisms in the water making it suitable to drink.

Finally, another crew member discussed the aspect of the ‘plank owners’. This is an individual who was a member of the crew of a ship when that ship was placed in commission. So since PISCES was commission on November 6, 2009 and the entire crew that is with me now on the ship was a member of the crew then they are all the plank owners of PISCES and I am the office plank owner Teacher at Sea!
