05-Jan-2002: Photo descriptions are not all typed up yet. ----------------------------------------------------- Picture descripts from TTN136B - Kurt Schwehr Role #'s are based on developer numbers from SavOn and Kodak 1st Role 779-08 Flying into Eureka. First landing attempt was a pass. We went up and around over the ocean for another try. Saw a while on our pass. This is looking south to down town Eureka on the right. 779-09 A mansion in down town eureka. It's a private club of some sort. 779-11 Looking west from the road out to the bluff. Jenna and I had just taken a walk at the nature presurve just off the highway (about ˝ - 1 mile?). This is the very southern part of the bay. 779-12 This is at the end of the road. There is a locked gate blocking the road just before it goes down the hill. Looking north. Can't quite make out the paper mill. 779-13 Just to the right of 779-12. 779-14 Wind swept pine tree. 779-15 Pete, Chris, ?, and Rob. I think this is core 3 about to be extruded. Rob is off to find a piece of wood to put on the bars off the side so that we wouldn't loose the core catcher in the ocean. Cores 1 and 2 were done during Friday night (the first night at sea). 779-16 JP, Denise?, Stef?, Jenna?, Robin, Kurt Processing a section of the core. 779-17 JP, Pete, Denise, Stef, Jenna, Robin, Kurt (leaning down). Processing the very top of the core. Have to cut off the top of the PVC to get out the piston. Then syphan off the top water to find the top of the core. Put a tape measure down until it hits the mud. Then measure the same distance down the core and mark the top of the mud. Then cut it. The stuff at the top is really soupy. The green brown container on the right has the OSU coring supplies in it. 779-18 Kurt, JP, Denise, Jenna. Don't know what we are looking out at. I tried to carry the yellow field book in my fanny pack. It didn't work so well. Used the fanny pack mostly for the electrical tape and markers. We were always having to ask who had what tool… tape, tape measure, markers, screw drivers. Should have brought monofillament line and given a bit to each person for splitting sections. Worked better than the putty knife or the twist and slide method. 779-19 Chris Jenna, JP, Denise We may be looking for the whale we say. This is the OSU HiAb crane. It has two winches. Visible is the one with rope line. Not visible is the wire line winch that broke. The chief engineer came out and tried to fix it with no luck. 779-20 Both cranes in action. The main crain is hooked onto the weight with the friction device and trigger hook. The scope wire is taped on the trigger arm. The HiAb is lowering the trigger core. 779-21 Chris, Tony, Pete I think this is core #4 sice Tony is on Duty. Chris is operating the HiAb while Tony and Pete hook the trigger core to the trigger arm. 779-22 Looking through the work room out to the sutar box core and the A-frame. Standing in the staging bay. In the front are three stanchions we use for working on cores. The sea gulls like to perch on top of the A- frame. 779-24 The CTD and water sampling cage. CTD, oxengen, and other instruments are located at the bottom. 779-25 Tony, 1st Mate, and Pete? Working on getting the trigger core set up. 2nd Role 783-01 Chief Mate? He is working with the crane operator to get the piston core past the bottom of the ship. 783-02 Pete, Tony, Rick, Chris Pete is using a large air drill to remove the nuts on the friction device. 783-04 Rick is having the crane raise up the piston core now that the trigger core and friction device have been taken off. 783-05 Chris is moving over the trigger core to the staging bay. 783-06 Rick, Chris, Pete, Tony The weight (4000lbs) and piston core barrel are just coming up out of the water. At the bottom of the image, you can see that the first bar along side of the ship has to be back out of the way for the core to be swung up to vertical. It is then placed under the core barrel to support it. 783-08 Rick, Pete, Chris, Tony, Engineer Rick is giving the crane operator the signal to bring the weight into the blue weight stand. 783-09 Rick, Pete, Chris Corer is about to go into the weight stand. 783-10 Rick, Pete, Chris, Tony The core is in the weight stand and about to be secured. 783-13 Kurt, Stef, Jose, Robin. Jose is cutting off the empty top core liner from the trigger core while the rest of us hold the core in place to keep it from rotating. 783-14 Robin, Denise, JP, Jenna, Kurt, Pete Engineers are working on the HiAb in the background. Stef is in the foreground cutting the top sections of the piston core. The wire is coming out of the end of the core barrel. 783-15 Stef, Denise, JP, Robin, Jenna, Kurt, Pete, Chris Engineers in the background. I am cutting off the top section while JP holds the top. This one caused a little trouble. 783-16 Stef, Denise, JP, Robin, Jenna, Kurt, Pete, Chris Can see the mud from the core hanging out. 783-17 Jenna, Denise, JP, Jose, Stef. Relaxing in the main science room after finishing a core. 783-19 Chris using the HiAb during the night time coring. 783-22 Kurt changing out of boots and into tennis shoes so as to not track mud all through the ship. 783-23 Stef in the main science room. 783-24 Jenna changing out of work gear in the main science lab. 783-25 I think this was an attempt to photograph the tail of the whale we saw. 3rd Role 780-01 Jenna and Denise handling a section of the core as it is pushed out of the core berel. This is probably the bottom 10 meters of the core. After the crown bit(?What was I trying to say??) are removed, the bottom end of the core is capped. Then the pusher rods are used to extrude the core out the bottom. There is a compressed air pusher, but Pete said it is a real pain. 780-02 Denise, Jenna, Robin, Kurt, Stef, Jose, ?, Chris Preparing to move the top 20 feet of the core from the bars on the side of the ship to the deck stanchions. It was hard to move around this crowded area with a long heavy core. Jpse is making sure all the stanchions are the right direction. 780-03 Chris, ?, Stef, Kurt, Jenna?, Denise, Robin?, Jose We have just moved the top 20 feet from the outer bars to the deck stanchions. Chris is pulling the cable that runs down the barrel to the piston which is wedged in the top of the core. On the deck by Chris' feet is the metal bottom fitting. This is the piece that holds the the core catcher and has a sharp bottom end for penetrating the sediment. Many of the core catrchers were mangled. After the first two cores, Pete added the board under the end of the core barrel to keep the bottom fitting and the core catcher from running too far. The rope seen on the bottom fitting is attached before the restraining pin is removed. As on core 1, gas can send the bottom piece shooting off. This keeps it from sailing off into the ocean. Cores 1 and 4 were gassy enough to push off the cap. Behind Jose is the rack that holds core barrel sections. The push rods are stored in the top left barrel section. 780-04 Pete, Jose, Robin, Jenna, Denise, Kurt. When the tuve comes up, it is pretty muddy. We had to towel down the core to remove mud and water before we can tape on end caps. To put on end caps, the standard way is to "burp" the core by sliding a standard (flathead) screw driver under the cap lib to allow air or water to get out as the cap is pushed on. Since we waterd a small hole in the end caps to allow the cores to degass without forcing off the end caps, we typically punched a hole with a screwdriver or putty knife as the end cap went on. Denise is about to use electrical tape to seal the edges of the end cap. 780-05 Pete, Chris, Jose, Stef, Kurt, Denise When the core is layed on the stanchions, we measuire off 150 cm sections. Then ove group cleans and labels the center of each section. We label two sides of the core so when it is split, both will have labels. Marking was done without knowledge of where it will be split. Jose is about to use the large pipe cutters at the mark by his left hand. It takes at least one other person to hold the core while someone cuts. Using the pipe cutters can be tricky. The correct way to turn them is counter intuitive. We had trouble with old blades breaking off and getting lodged in the cut. 780-06 ?, Jose, Denise, Kurt, Robin. Robin is marking the bottom of the core with "BOT." 780-07 Denise, Jose, Kurt, Pete Jose is in the process of cutting the core liner. Near the top of the core, mud ofter comes out once you first break through the liner. This makes the cutter slippery and hard to use. 780-08 Denise, Jose Here you can see mud coming though where Jose has already broken through. Once through, it is hard to keep the cutter corretly on the surface. The blade sinks into the core and lossens grip of the tool. Then you are trying to cut all of the PVC left at once. 780-09 Kurt, ?, Stef. Stef has the putty knife we used to cut the mud petween two core sections. Sometimes, the mud is pretty stiff. 780-11 ?, Jose, Denise, Stef. Just after Stef cut the mud with the putty knife, Jose is about to put on a "BOT" end cap. The mud looks solid. Each "work vest" has a safety strobe light for if you end up overboard at night. 780-12 Robin, Stef Robin is labeling the top of a section with an up arrow. After so many hours of work and not much sleep, I can't believe how cheerful everyone was. 780-13 Jose, Chris, Kurt, Denise Jose is cutting the liner while Kurt and Denise hold each side. 780-14 ?, Jose, Pete, Denise, Kurt, Chris, ? Mate, Robin, Jenna Jose inspects the pipe cutter and progress cutting. 780-15 Kurt, Denise, Jenna, Robin. Jenna looks like she is having fun. 780-16 JP, Jose They are securing the last of the cores in the reefer (fridge). There was some excellent know work between the undergrads and JP. 780-17 Jose, JP JP ties up the one last really long section of the core to the wall. 780-18 Chris, Denise, Jenna. Denise usees left over mud as war paint. At this point, we are done coring and Chris is breaking down the coring gear. (Is this right??) They had about an hour and a half of work to do over the edge of the ship. The ship can't be underway while people work over the railings. Jenna is holding the Ziplock bag with mud from the core catcher. 780-19 Evening sets on Sunday. Looking aft from the 02 deck as we do hydrosweep. 780-20 Failed attempt to replicate the from the bow dophin picture. Ship reflected in the water without a flash. 780-20 Same as 780-20 but with a flash. 780-22 Left to right: Kurt, Chris, Stef, Robin, Jose, Denise, JP, Jenna, Pete. The science team, but missing Rob and Tony. We are in the computer room. I am leanin up against the hydrosweep console. Behind Jose's head is the wind speed and direction display. Can't remember what display is behind Pete's head. Then at the edge is the cable/wire tension and length out displays and graph. The secondary ship controls are what Pete is leaning against. 780-23 Same at 780-23 638-01 The brid that drove Rob crazy. Whenever the door from the deck to the main science lab was left open, it would come in. It pooped on the walls and computers. Rob had Stef chase the bird around trying to get it out of the ship. This shop is in the main scince room nect to the door to the computer room. 638-02 The bird posing b y a whindow in the computer room. 638-03 Jose working on his chemistry in the computer room. There was a TV/VCR in there so people would grab movies for us to watch while we worked. Behind Jose is the CISCO 2600(?) router for the ship. The area to the left is where Rob and Tony tended to hang out with all the computers. 638-04 Dolphins racing along side the ship. 638-05 JP, Denise, Stef watching the dolphins on the aft deck, port side. 638-06 Dolphins 638-07 Dolphins 638-08 Denise, JP, Stef, Engineer watching the dolphins from the aft deck. 638-09 Denise, JP, Stef, Engineer. Two dolphions are right nect to the rear of the ship. Can just make out their splashes. 638-10 Jose getting ready to deploy the CTD cage. This was between hydrosweeping and the last core. The CTD will provide a sound velocity profile to use with the hydrosweep data. 638-11 Stef and Jose. Jose is standing on the cage checking out the trigger mechanism for the water sampling bottles. (Nansen bottles?) 638-12 Stef and Jose inspecting the water samplers. 638-13 Stef, Jose, Robin Getting the CTD ready to deploy. 638-14 Robin, Jose, Stef Jose and Stef guide and steady the CTD cage as it is taken out over the side of the ship. 638-15 Robin, Stef, Jose guid e the CTD over the side. 638-16 Robin, Stef, Jose guid e the CTD over the side. 638-17 Robin, Stef, Jose send the CTD on its way. 638-18 CTD cage under water on its way down. 638-19 Really good view of the CTD cage underwater. 638-20 Denise and JP in the computer room. Behind Denise on the side of the rack is the berthing/sleeping assignments and calendar. Inside this rack is the stereo system. Behind JP is the Linux box use dto display hydrosweep progress with MB-system and ghostview. They used Afterstep for a window manager. 638-21 Kurt The CTD cage is coming back onboard. I am waiting to guide it to where it will be strapped back down. 638-22 Chris, Kurt, JP. Getting ready to steady the CTD cage. It is swinging around pretty good. 638-23 Chris, Kurt, JP. The CTD is almost back in place. Chris is reading the piston coreer for the next and last core (#7). 638-24 Jenna and Denise on the 02 deck. 638-25 Jenna and Denise on the 02 deck. 5th Role 781-01 Kurt standing one deck above the main deck with my eyes closed. 781-02 Same as 781-01 but with eyes open. Can see the separate crane for the CTD and rosette cage. The crane has only 1 degree of freedom. 781-03 Denise with a trigger core ready for deployment. In the front, you can see the core catcher basket inside the metal housing. The bottom edge is pretty sharp. 781-04 Gray, Tony, Pete Getting the trigger arm and scope cable ready. Someone has to hold down the trigger arm or the main core can come unhooked. The trigger core is ready to get hooked up and is sitting by their feet. 781-05 Robin sitting on a big winch of some sort watching the setup from a safe distance. This must be Sunday morning. 781-06 JP, Tony, Pete Pete is guiding the trigger core into place. Above the lip of the weight stand is the loop of the 4000 lbs weight that drives the core in. Attached to the loop is the friction device with the trigger arm. The scope is taped on with electrical tape to the trigger arm. I am not shure what the black foam ring on the trigger core is for. 781-07 Gray, JP, Tony, Pete The trigger core has been lowered into place and been attached. 781-08 Chris, Gray, Tony Pete Gray is giving the start down signal to the crane operator. The piston core will be lowered very slowly until it is past the bottom of the ship. The wire out is zeroed when which part hits the water? 781-09 Denise, Pete, Jose, Kurt, Gray, Tony, Jenna, JP While the core is on its way down, we wait in the main computer room. We filled out OSU core report forms for each core. We watched the displays behind the pole to get wire tensions and to see where in the process we are. Between the last two minotrs on the left is the output of the ships gyros. 781-10 Gray and Pete Gray is watching over the cores as they are on the way up along side the boat. Pete is ready with the rope used to pull up the trigger core. The normal winch on the HiAb broke during core 3 (I think). 781-11 Gray, Pete, Tony, Chris. Just before the friction device breaks the surface. You can see the first two bars on the side of the ship are out of the way for when the core is rotated up along side. 781-12 Gray, Pete, Chris, Tony Gray is telling the bridge to bring in some more line. 781-13 Gray, Pete, Chris Gray is tetting the crane to mive in towards the ship. The friction device and trigger arm are at a height that Pete can get to them. 781-14 Pete and Chris Pete has attached the trigger core to the HiAb and is bringing it up along side the ship. The friction decive and trigger arm are still attached to the line with the piston core on it. 781-15 Tony, JP, Kurt Chris lifted up the trigger core. We then pull the core into the ship and the three of us pull the core into the staging bay and place the top of the core on a stanchion. 781-16 JP, Kurt, Jose, Pete, Tony Pete is unhooking the trigger core from the HiAb's 2nd winch. 781-17 Kurt, Robin, Jose. Robin is using a large socket wrench to remove the four bolts that hold on the top bracket. In the background is the rack of core liner. I don't know why they had thinner liner along too. Maybe for the previous ops before my cruise. 781-18 Gray and Pete The core is now firmly attached to the weight stand. 781-19 Jose, Jenna, and Logan. Jenna is drilling out the grommets that hold hown the end fitting and core catcher. The bottom of the fitting is pretty sharp so as to penetrate the mud much more efficiently. 781-20 Robin, Jenna, Jose, Denise They have just split the trigger core into two sections. Jose is holding up the uncapped top of the bottom section. 781-21 Pete and Chris They are attaching the push tods to the top of the piston core so that it can be pushed out. 781-22 Jenna, Robin, Stef Waiting for the chance to work on the next core. A good view of the sutar box core in the top right of the picture. 781-23 JP, Gray, Kurt, Stef, Robin, Pete, Chris Jenna, Jose Can see chris holding the push rod as Pete attaches it. 781-24 Jenna, Denise, Robin Jenna is capping the bottom of the core before it is pushed out the bottom. 781-25 Denise, Robin, Kurt, Jenna. Denise is passing the core over the lip of the wood on to Robin. We have to stop when the end of the first section comes out so we don't pull much mud out of the tubes. 6th Role 77801 On the evening of the 4th, Sunday, all of the science team except myself and the two marine techs had to get off on a tug to go back to Eureka. The Thompson was very stable, but the tug (Koos Bay?) was definitely not. It was a scary transit from one to the other. I think this shot shows the deck hands working the rope lader into place. 778-02 This shot shows someone climbing down the rope ladder to the tug. I didn't use a flash because distracting people could put them at serious risk. From all the straks of the tug, you can see how much it is moving. I was using 400 speed Kodak Max Film. Should have had 800 for this shot.
