Hello all,
The last full week of being out on the R/V Hugh R. Sharp, what a wonderful time it was. This was probably the easiest time for me with mostly demobilization and remobilization for a one-day cruise with the Office of Naval Research. The plan was to deploy four bottom mounts and one line of small sensors, then finally a few days to enjoy Delaware for all its flat glory.
For Sunday, we arrived to Lewes around 0500, but since we got in when it was low tide, we couldn’t go into the channel until 0700. We were all just waiting ducks until the tide started to rise. The final tie off for the scallop trip finally ended. Since everyone was beat from the past few weeks, everyone tried to leave early to get some actual sleep in their beds and rest up for a demobilization and remobilization for a two-day cruise working with the Office of Naval Research. The boat was tied off in an easier fashion due to the nature of having lines on the dock instead of throwing them overboard. By 1200, the majority of the crew had left. All we ended up completing was removing trash. Tomorrow will be a hard day.
We ended up with Christian later that night where he showed us around Rehoboth, DE. WE had some food a one of the restaurants and went back to the ship for an early 0700 morning. An early day to sleep at last.
For Monday, an early morning to get all the large equipment off the deck and a few items onto the deck. We started around 0700 where we started with removing the sorting table, dredge ramp, HABCAM ramp, and HABCAM tracks. This part was mostly easy; we just needed to hook up lifting straps to the crane and move it to the shore where one of the shore-support would get the forklift move the items back to their spots. We spend a good few hours removing these large items. The last major removal was the laboratory van which was a little bit more involved due to a rigid metal lifting harness needed to be attached to the crane and then lifted to the van. We had to get on top of the van to attach the metal harness to van and off went the van. Next was washing the deck with ‘on-off rust remover’ to remove the rust that had built up being at sea. While I was working on that, a few guys removed the port side winch block as it was not going to be used for the next cruise with the Office of Naval Research
After everything that could be taken off was, now its time to add some gear to the deck. We added a Zodiac type boat, as they call it a NAZ (not a zodiac) back to the 01 deck where it normally is; we added a huge 7200 pound winch to the center of the deck; we added a couple of cleats near the A-frame and the rails back to the port side of the deck; and we added a few counter weights as the winch was shifting the boat a little to starboard. All was easily done with the crane, a few lifting straps, shackles, and a tag line or two. We secured all the items with either bolts or rachet straps. By this time the science team had arrived, but they were working in the low bay in the operations building to work on getting their two spider bottom mounts and two larger platform bottom mounts ready for deployment on Wednesday. This was basically the end of our day as well because we got most everything done.
Later that day, the cook, Hunter, took Shaun, Huxley and I to Dewey Beach to show us the little beach town. It was an interesting place that reminded be of a smaller Jersey Shore. Beaches and restaurants all around. Unfortunately, it started to rain a few hours in, and we ended up leaving back to the ship. I was able to get a good night sleep to keep getting ready for tomorrow.
For Tuesday, another early morning at 0700, a great time to wake up with so much time having to finally sleep. After breakfast, Christian gave Shaun and I news that we needed to get the multibeam set up and installed before we leave tonight as it was a last-minute addition to the cruise plan. The multibeam was stored in a cargo container, but it wasn’t clean since they removed it, so a lot of TLC was needed before it was ready to be used. We also needed to take out one of the unused pods currently in the keel to put it in its place. Christian and Tim Deering were showing me the tricks of the trade to clean it off. I was using wooden dowels to scrap off the buildup of mud and barnacles. They did this because it was a soft and wouldn’t scratch the transducers. I will tell you; it took many hours of cleaning because they were satisfied with it. We also had to replace a couple zinc plates and rinse with water. Once it was cleaned, the other trick they told me to use for anti-fouling was vacuum grease and cayenne pepper. Tim told me fishermen used to use this for anti-fouling as paint cost too much as the time. Once greased up, we were good to move it to the ship. All the while, Shaun had been removing the metal grate that holds the pod in place in the keel so that it could be removed with the crane. First, lunch with sandwiches from the local sandwich shop. As soon as got done, we got the old empty keel pod out by Christian and Shaun going in the keel and hooking up to the crane. Huxley and I were guiding it out as the crane operator rose it up. A line was tied to it and we guided it back to shore where it was placed on the forklift. Next, we lifted the multibeam pod and placed it into the keel. This time I went down to put and tighten the grate. Then we ran the cable through the passage and into the dry-lab where we hooked it up to the computer. We finally got it all hooked up and it was ready to go. Most of the crew had left at this point, but soon the science team would start loading all their gear. All we needed was a forklift driver, a crane operator and Shaun, Huxley and I. We started with the gravity corer attached to a wooden frame, then the two spider bottom mounts, an hour later the two platform bottom mounts. We talked with the science team on how to secure all them down, then we went at it. A few large containers were added, and everything was on board. The plan was to leave at 2000 and start the next day at 0500. The crew came back around 1900 and we started off. Since all the deployments were during the day, Christian, Shaun, Huxley and I went to bed shortly after.
For Wednesday, another early morning at 0500 this morning. We were getting ourselves ready before the science team wake up. The game place was to deploy a platform, then a spider, then a platform and lastly a spider. Before each deployment we would do a corer sample to make sure we at an acceptable location and deploy. After everything is in, we will do a little multibeam over the sites and back to Lewes.
The first deployment of the platform was pretty quick. After we had to core sample finished, we used the winch to and four tag lines to inch it close to the transom until right at station. The science team had rigged up a removal compass to adjust the direction of the platform once in the water. Ever so slightly, they inched it closer with four men on the tag lines. It went over without any problems. It did take some time to get the compass right as the current and the boat made it a bit difficult. A couple of surface floats were laid out and the first site was done. Next was a spider which was easily moved into position by five men. We had to rig up two shackles to the side of the A-frame to get a line around the spider to lower it into the water easily, this was done pretty easily with two people on the spider to stabilize it. The first one went in without a problem, we adjusted its direction and it went in without a problem. Lunch time was shortly after then the last two. Another core sample was taken and another platform was released into the water. Again pretty quick and easy. The last spider was set in as well a little while later without an issue and we were done with everything on deck. The final task was the multibeam.
They had one of their personnel working on the multibeam, but she hadn’t used it in some time and our crew was not fully familiar with the system. I spent much time watching her figure out how to set up the system, get a base map, plot points, and figure out what was needed for the calibration test. Roll, pitch and yaw we needed to be calibrated using flat points in the water with two lines going in opposite directions for each variable. Once she figured out good points, we get the boat driver geared up to follow transect lines and we off. It took a good three hours before getting to this point, but only one and half hours was needed to actually perform the passes. Once we made multiple passes across the transect line for the bottom mount sites and calibration, we set for Lewes. By 2000, all was said and done back at the dock and ready for bed.
For Thursday, the demobilization was a quick one today, with mostly just the bins and corer needing to be removed from the deck. This took maybe two hours and our day was over. All the science team were quick to leave by 0900 and my time aboard the Hugh R. Sharp was basically over. No more work was going to be getting done as the crew was taking a short vacation after being out at sea for so long.
I spend the last few days in Delaware going around with Christian to show me the sights. I saw downtown Lewes with a few restaurants, but mostly I hung out with the graduate students for the University of Delaware. I talked with them about their projects and the type of work they were doing. By Monday morning, I was back in Florida and ready to take on the next part of my life. The last few days were quick, but unfortunately not much occurred after all the work was done for. I had to prep for a cruise with the Ocean Circulation Lab at the USF College of Marine Science so much time was spent getting all my needed paperwork for that.
This had been an amazing experience, with lost of meeting of people and learning much about being a marine technician. I think I want to pursue a master’s degree after being a part of all this from talking with the different scientist involved. Here comes my next phase!
A bittersweet time to leave. I had too much fun and worked extremely hard to learn what it takes to be a marine technician. I found my enjoyment of all the tasks at hand, but I feel a strong pull in specializing with a master’s degree. I definitely loved doing the work, but I’m feeling very motivated from all these experiences to keep it going and get a higher education degree in oceanography. I want to be out at sea and collecting data for my own research projects. I am definitely more affective when being on deck and collecting data, so I should use this experience to continue that for whatever I get into with it. I’m super appreciate for every opportunity I got in this; I really felt like part of the crew when I was here. Time to get myself in gear and get to grad school! Thanks for everything Christian, Huxley, Tim D., Tim N, Andy, Chuck, Hunter, Pam, Chris, Casey, Jimmy, Joe, and all the science team. I will never forget this and will continue to strive for greatness.
Best,
-Sebastian D.
