Fun with Dredging

         The dredging has set in full force. We dredged for three days nonstop save for the occasional repair to the dredge. My job is assisting in bringing a dredge up out of the sea onto the table, dumping the contents, and setting it it back out again. Once a dredge is completed the deck has to be washed down with the seawater hose as there is a surprising amount of organic debris left from the dredge. A dredge takes around an hour to complete depending on what we catch. The ease of the dredge entirely depends on what is hauled up. Those that are filled with large rocks, are sandy or muddy, and those that are extremely large in quantity are the hardest to shovel and sort. I’ve seen all sorts of amazing creatures that were caught in the dredge. Not only have there been scallops, but I have seen octopuses, squid, mussels, monk fish, skates, hermit crabs, sand dollars and sea stars at the top of my head. The first few days of the week were consumed by continuous dredging and made for quick but arduous watches.

         Shortly into the beginning of my watch on June 1st, we did one last dredge before we secured the dredge on deck. It was time to head into Woods Hole, MA to refuel. We steamed into port at around 9:30 am and had a couple of hours off until it was time to head out again. Before I could go and explore the town, we had to dump the garbage. This was a fun process of chucking trash bags over the side of the Sharp onto the dock where the bags were then brought to the trash bins nearby.  I enjoyed wandering the town and in particular enjoyed the food and coffee at a cafe called Pie in the Sky. All too quickly, it was time to head back to the ship and we were off by noon.

            The next watch, the midnight since leaving Woods Hole, the sea had picked up considerably and there were strong winds. We were not able to dredge in this weather and all we could do for hours was wait for the weather to die down. By daybreak the seas had calmed and we were able to place the Habcam in the water. As Habcaming requires nothing of the techs, the day was spent peacefully and quietly up in the bridge. The peace was broken by the time my next watch began on the 3rd. When I woke up we were back to dredging since the one of the computers of the Habcam had broken. One of the dredges we pulled up that early morning was of note, we had caught ourselves an old lobster trap, two lobsters included! After breakfast we got great news from science saying that they fixed the computer and the Habcam was ready to be put back in. Once it was deployed, there have been no further issues and we have been Habcaming up until today. Tomorrow we will be back to dredging but we had a certainly had a nice break.

See  you next week,

RV Langseth: First week out at sea

This past week has been very busy. We spent all weekend getting ready to head out on Monday. I spent most of my weekend rebuilding the air guns. We were able to leave port about 9 am on Monday morning. While transiting to the survey site we deployed the cross cable, doors, and head floats. The doors are 4m tall floats that have fins designed to spread the cross cable to cover the intended area. While deploying and recovering the doors my job was to help disconnect the lift ropes and then run the 50 Ton winches that let the doors out and in. We were able to fully deploy the p-cable and streamer on Tuesday but we had to fix a few issues. Last night I got my first try as a data acquisition technician. This means that I was in charge of making sure the guns were firing at a proper rate and also logging any shots that were missed or not recorded.

            One of the best things about living on a boat is the food. Every night we have had a different meal. We have had everything from fish, steak and scallops, to chicken, potatoes, and pie. I will try and post next Wednesday but it depends on how well the mission is going.

Quick update

Been awhile since my last detailed post, but time flies and I’ve been way too busy to even muster the urge to type anything useful.  

This last week I had the fortune to work aboard the USCGC Healy for a 4 day shakedown cruise.  The goal of a shakedown cruise is to get all of the science and technical aspects working since the ship had been sitting essentially unused for a few months.  Dusting off the cobwebs on computer based systems are always fun because they always seem to turn on with new issues. Overall our cruise went well, with the main exception being the 4 hour delay due to engine failure before we left the dock.  Our main issues revolved around the Met System that displays the flow through information, the multibeam, and the CTD.  

On the cruise I learned and practiced many useful techniques.  Its amazing how every technician you meet has a different way of doing things, a prime example being CTD terminations.  On the shakedown cruise my OSU tech coworker and I got to work with some awesome Scripps technicians since the Healy shipboard tech support group is made up of a collaboration of OSU and Scripps (STARC) and the Coast Guard’s MSTs and ESUs.  Overall it was a great experience.  

As for present day.  I am currently back in Corvallis Oregon working in our office space.  I am still inventorying the multiple boxes of Triaxus related gear before I can even think about piecing it together. However I only have till Sunday before I fly off to meet the R/V Oceanus for a month at sea.  I am hoping my coworker starts to feel better otherwise I may be the lead marine tech running this upcoming cruise.  It would be entertaining and fun to run the cruise for sure, but I still have to read over the cruise plan and expected science to be completed.
