I was sent to join this cruise half way through because a lot of the scientific party had to leave and nobody more qualified than me could be found at such short notice! I have never been on a cruise before and had no idea what to expect, or any idea how complex and time consuming 3D seismic acquisition is. I have learnt so much about the technical side of acquisition and a little bit about the processing side; however I have also gained a lot of non-scientific tips and tricks!
Here are my top 5 tips:
1) ‘Boring science is good science’ – If you are bored on a 6 hour watch that is a good thing because it means that everything is running smoothly and good data is being collected. Having things to do is always a bad sign! Things have been running pretty well recently and as a result I have greatly improved my crossword skills.
2) Things will break, don’t panic! – This is a hand me down ship filled with second-hand instruments from industry vessels. Because of this a lot of the equipment is temperamental and repeatedly needs to be fixed. However, I have also seen instruments that have been offline for days randomly start working again so you never know!
3) Duck tape has a million uses – There is no end to the list of things duck tape is used for on this ship: keeping weights in place on streamers, keeping your laptop on the desk during bad weather, taping your ladder to your bunk so it doesn’t bang during rough weather and keeping ropes in place on the deck to name a few. It seems like any problem can be fixed with tape.
If you don't want your office chair rolling around or you need a cable tie just use tape!
4) Hoard food – When food you like is put out in the mess then take it while you can. A few days ago a gigantic tub of mini snickers and bounty bars was put out in the mess….I have never seen chocolate disappear so fast!
5) Taking a shower is the most dangerous activity on the ship – I recommend keeping either an elbow or hand on the wall at all times so you can feel when you start to move. I think taking a shower is probably the best form of exercise on the ship because of the amount of effort and energy it takes just to balance. Also, never soap the bottom of your feet in rough seas. That is probably classified as an extreme sport!

Located next to the Galley we have our Library which has a lot of good books (I was reading the Che Guevara's travel book before the beginning of this part II, I really want to finish it!) and these excellent chairs...they're really comfortable, believe me. You can also find a variety of mystery, fiction and scientific books on the shelves.
The library with a wide variety of books
Yeah, but John actually I'm not a book lover ...No problem! This is what you need! A 42-inch TV screen and a big collection of movies and TV shows. Ah, and don't forget the PS3, which makes the crew's free-time fun. I have to admit something to you, I've never used the movie room, but maybe sometime I will go there to catch a movie or documentary.The movie room with seating for plentyBut if you're an athletic person, this is your place, the gym!
It's a little bit small, but if you think we're in the middle of the ocean, the luxury of having some equipment must be appreciated.
The gym ... be careful when the ship is moving!So, there is a treadmill, some free weights, etc. Be aware of the pitch, roll and heave! These are the movements made by the ship. Instead of explaining them, I'll post an image which can perfectly illustrate what I'm trying to say.
The differences between pitching, rolling, and heavingFor those who appreciate an indoor sport, we also have a ping-pong table. It's located one level below the Galley, at the Main Deck. I didn't use this table either, but I'll launch a challenge: Try to play ping-pong during rough seas! Imagine how cool a ping-pong game is inside a ship facing waves of 5 or 7m (or even higher).
The ping pong table ... this could get interesting in rough seasThank you...or should I say Obrigado?

The back of the lab where most of the preprocessing and quality control is done.Additionally, we use this bank of terminals to monitor for the presence of critters in the water, the weather and sea conditions, and the health of the EM122 multi-beam. Sitting back from the semi-circle of computers is another set of desks where the we, the students and scientists, stake our claim. Outfitted with no-slip fabric and duck tape, we have covered the back of the room with our computers, which we use for pre-processing and quality control (QC) of the incoming data.
That about covers the main lab, they keep it pretty cold down here for the sake of the computers so I’m headed up to grab another sweatshirt before I get frost bite. Stay warm out there!
For those of you who have been following our adventure here's a comparison of the sea-state. I know that the few of us who have been out here for both halves definitely appreciate the difference, and for those joining for the second half it looks like smooth seas ahead!
Also, we have now reached 10,000 page views!! So thanks Mom (and everybody else).

We started our tour of the R/V Langseth almost a month ago with a walk through of the mess hall and now with our return to the high seas are excited to pick back up where we left off. Let’s begin with our sleeping quarters.
As we all know, the most important aspect of real estate is location, location, location and the same can be said for room assignments when at sea. On first glance, you might be tempted to opt for a room on a higher floor accompanied by a nice porthole to allow full view of the spectacular sea outside. However, hold that thought! Remember that the further above sea level you are, the more you will move with each passing wave. What may feel like a peaceful sway down on the lower levels can turn into a ferocious veer strong enough to topple chairs on the top deck. Thus, if you have any inclination that you could succumb to seasickness it is probably best to pass on the picturesque vista and opt instead for a windowless cabin below. Fortunately, for many of the scientists mental struggles over room selection never occurred as cabins had been assigned to us before we walked up the gangway. Most of the students aboard are sleeping in a suite of cabins that share a common living space endearingly termed the “Snake Pit”. The origin of the room’s namesake remains mysterious, perhaps previous groups of students did some sort of battle there? Or fought snakes? Who knows, for now though it represents a comfortable room where many spend their off time reading books from the library or taking short siestas in between work.
The "Snake Pit" where students read and lounge between shifts
All of the cabins aboard share similar features such as a set of bunk beds and matching closets. Depending on the individual setup, you might find yourself lucky enough to also have a set of desks and perhaps even a small couch though these furnishings are found mostly in the higher rooms reserved for the principle scientists and the superior ship mates. Given that work continues around the clock on the Langseth, all bunk beds include an individual light for private reading and also black out drapes to both prevent any light from your bed reaching your room mate and conversely any light from your room mate reaching you. Additionally, all rooms come with either adjoining shared or private bathrooms (termed “heads”). Given the combination of rolling waves and slippery tiles, it could easily be said that the heads may be some of the most injury prone rooms aboard. Thus whenever attempting to take a shower, remember to always keep one hand on the hand rail and if the ship starts swaying don’t neglect to hold on tight otherwise you might suddenly find yourself autonomously ejected onto the cold, wet floor.

I think that about does it for now, dinnertime is just around the corner and I can smell the ahi tuna from here. Buenas Noches!
Being at sea again allows me to look back at our extended stay in Vigo (Galicia). The port city of Vigo is a unique and beautiful place. The summer months are particularly nice as this part of the Atlantic coast is rainy most of the year. Vigo is just about 2hrs north of Porto (Port wine), which is in Portugal. The proximity to Portugal and the fact that in the past teaching the English language was not stressed within the school system leads to a population that speaks a mixture of Portuguese and Spanish, but not much English. As a result my (poor) Spanish was definitely put to the test as well as my ability to communicate using what are best described as elementary level sketches.
What Vigoites lack in English they make up in hospitality and a relaxed outlook on life. In short, the idea of a "siesta" is not lost on them. While the bars (and there are hundreds if not thousands) are usually open, the restaurants do not open until 8:30 p.m., and generally not at all on Sunday. However, we did manage to find one that is, and it happened to have very good (and cheap) Tapas. Although off the beaten path it quickly became one of our favorites.
A view down the alley to one of our favorite bar/restaurants.Vigo also has some amazing beaches! After what amounted to a 45 minute walk or a 6 Euro (~$8) cab ride from the ship we could either lay a towel down and get some sun or grab a drink at one of the bars that are literally on the sand. I was shocked to say the least in the shear number of people that were at the beach, and it seemed like there were more during the weekdays than the weekends. Must have something to do with the laid back lifestyle (?)
Playa Samil on a Tuesday.The best beach (Rodas) in the world (The Guardian, 2007) can be found on one of three islands about 45 minutes (16 Euro, ~$20) by ferry named Illas Cies. The archipelago of Cies is also a Spanish National Park. An interesting thing about these islands is that they look like an above sea analog to what we are seeing sub-seafloor in the data. That is to say that they consist of a series of faulted crustal blocks (granite). The style of faulting is termed "Normal," which means that the hanging wall moved down relative to the foot wall. This type of faulting is indicative of extension and is expected along the length of this margin.
A view of Cies from Playa Samil with faults indicated by the arrows.The part that we had been so patiently waiting for arrived after almost 3 weeks in this unique place. While I will not miss being in port, I am happy to have had the chance to see and experience this part of the world as it truly is a beautiful place.

Welcome back to our blog! As of yesterday morning, we are back at sea and shortly we will resume acquiring 3D data. The repairs to the engine were more difficult than originally thought. We had the Rolls Royce engineers with us for the whole time, working with our fine engineers on the ship. You may not know that Rolls Royce makes really big engines like those in the Langseth. They worked to clean out the engine, ordered a number of parts, and the parts gradually arrived in Vigo. The engine was reassembled and tested at the dock. It worked again!We sailed from Vigo at 0700 on 15 July with a partially new science team. Several people left the ship because they had conflicts with the extended cruise. They were Donna, Tim, Cesar, Mari, Brian, Steve, Luke, Marianne, Miguel, and Toby. Remaining were Dale, James, Raj, and Sarah. We could hardly do with a science team of four, so we recruited six newcomers. They are Natalie Accardo (Lamont), Milena Marjonovic (Lamont), Gaye Bayrakci (Southampton), Joao Pedro Tauscheck Zielinski (Madrid), Tessa Gregory (Southampton), and Katherine Coates (Southampton). We will try to get photos and bios up shortly.We are deploying the seismic gear now. We have two streamers out and the third almost out. We hope to begin acquisition in the morning.We are all excited about continuing our cruise and completing the 3D survey.

It has been a while since we last updated this blog. The reasons are many. The primary reason for the delay is that we have had singular focus in launching our next project, a project that for many is a dream come true.
Before we launch into that and officially start the 2013 field season, let’s do a quick recap of our team’s efforts since last August.
Our academic year started with a bang: our new research project, which was an unexpected off shoot of our efforts to study climate, fire, and forest ecology, was funded by the National Science Foundation in September 2012.
Since then, our team has spent much time presenting prior results, new preliminary results and processing samples. Many, many samples.
First, kudos to Nicole Davi work improving a tree-ring based reconstruction of the Kherlen Gol in Mongolia (gol = river). Many of the chronologies used were collected between 2009 & 2011 as a part of the Climate, Fire, and Forest Ecology project. The new work, “Is eastern Mongolia drying? A long-term perspective of a multi-decadal trend” can be found here.
Second, we need to congratulate Cari Leland on persisting and publishing the first paper from her thesis: “A hydroclimatic regionalization of central Mongolia as inferred from tree rings “ – link
Cari’s effort set the stage for our second paper on the climate history of the Mongol Breadbasket: “Three centuries of shifting hydroclimatic regimes across the Mongolian Breadbasket“ – link
Finally, Tom Saladyga got a nice piece of his dissertation published with the article, “Privatization, Drought, and Fire Exclusion in the Tuul River Watershed, Mongolia“ – link
We have a few manuscripts in development from our Climate, Fire, and Forest history project, which ends in 2013. And, we are very happy that Byambaa is on the doorstep of completing her dissertation. This project is coming to a very nice completion and we are thrilled.
We are equally thrilled with the start of our new project, “Pluvials, Droughts, Energetics, and the Mongol Empire”. We’ve gotten a silly amount of press here, here, here, here, and here – it has been great. Both institutions have made nice videos and overviews of the project: here is an example of WVU‘s and here is LDEO‘s. Awareness of this project has been widespread. We meet new scholars from various parts of the world and it seems they are already familiar with the new study. Neil presented preliminary results at the PAGES meeting in Goa, India – that was hard work
Amy Hessl garnered two invites based upon our work. The first was a workshop primarily populated with historians on migration and empires across Eurasia. The setting and out-discipline experience was fantastic. The second was an archeology-based workshop on Chinggis Khaan in Jerusalem – sounds like that was equally hard work!
We are now gathering in Ulaanbaatar to launch the first season of ‘complete’ field work. By complete fieldwork, I mean that we will not only be collecting tree cores and cross-sections from dead trees, but Avery Shinneman Cook will be leading the effort in collecting lake sediments in central Mongolia to better understand long-term environmental history and the impact of the Mongol Empire on the landscape in and around the ancient capitol, Karakorum.
Prior to that, we will hold a 4-day workshop introducing ourselves to our wonderful and diverse team (a dream team? Besides Amy Hessl and Neil Pederson, team members include: Baatarbileg Nachin, Hanchin Tian, Nicola Di Cosmo, Avery Shinneman Cook, Kevin Anchukaitis, Oyunsanaa Byambasuren, and PhD students, Caroline Leland and John Quinn Burkhart) and their specific research. We will visit historical sites and lakes to begin the discussion on how to address some questions originally posed in our grant: did the rise of the Mongol Empire, driven literally by horsepower, benefit from an abundant climate and a surplus of ecosystem energy? Did the construction of the Mongol population, army, and herds of grazers significantly impact the landscape? Answers to the ful climatic context of the Mongol Empire has been a primary goal of the Mongolian-American Tree-RIng Project, (MATRIP) since the mid-1990s. We finally have the chance to address these questions. We do not know the answers yet, but stay tuned.
Brief Observations on an alternative approach to Mongolia:
This is my 9th trip to Mongolia. It is hard to believe that I have visited this far-away land so many times. But, when I smell the steppe as we enter the airport, I relax and hit a new mode that is akin to putting on old slippers. I go through customs with nary a concern knowing that Baatar will be waiting for me with a warm greeting and hug. The drive to UB is filled with the same conversation – “How are you? How is Mongolia? How are things going? How is your family? How are your students? My, Mongolia has changed“. It is wonderful.
What changed for me this year was how I got to Mongolia. I typically venture west and enter through eastern Asia. This time, I traveled east, stopping in Turkey, re-fueling in Bishkek, and then flying over western China and western Mongolia.
The sky was clear upon entering western China and the scenery was stunning. Really. I stopped my movie and just drooled out the window [akin to a dog?]. It adds a few hours of travel time at most, but I’d do it again.
