Meet the Doodlebuggers! Wait... what's a Doodlebugger?!

No seismic expedition is possible without it's hard-working Doodlebuggers! One of our own doodlebuggers, Shaun, gives us the full breakdown of seismic life at sea!

The official Doodlebugger patch
Doodlebugger:
As defined in the Urban Dictionary and edited for this blog: Term for field seismic personnel. Differentiated from a roughneck by their actual coarseness... Doodlebuggers search out oil, natural gas, and other precious commodities the world around by exciting the ground with explosives, drop weights, and more often than not pieces of specialized heavy equipment called vibrators or air guns. They work in the most extreme climates, brave the most dangerous countries, and suffer some of the worst wages in the oil and gas industry. Most importantly, doodlebuggers are renowned for their ability to drink. Doodlebuggers often work in camps in the middle of nowhere, and are rarely seen in their natural environment. Easily identified by their pot bellies and lack of shaving. They tell the BEST stories.... 

Meet Shaun!
Having worked as a Doodlebugger for close to 37 years, I have a pretty good idea of what the job entails and the lifestyle that it creates. 

In reality a Doodlebugger is a hardworking man or woman in the oil and gas industry, either on land or at sea on a seismic vessel. I can’t speak too much about the “Land Crews” but normally they work longer trips in worse environments than the ocean based crews (if the weather is ok).

Marine Doodlebuggers consist of 2 departments; Seismic and Maritime. The Maritime crew; Captain, Officers, Deck Hands, Engineers and last but certainly not least the Cooks and Stewards. Their role is to keep the vessel in “ship-shape” condition and running smoothly and safely. A well fed crew is always a happier crew. One Golden Rule, Never Annoy the Cook!!

The seismic crew is led by the Party Chief. He/She is the most senior member and in overall charge of the seismic activity and data quality. They work closely with the on board client reps and the office to ensure that the program is completed within the specifications and delivered on time to the client. As the title would suggest, The Party Chief is also in charge of buying at least a couple of rounds when the crew is back on land.

The 3 other roles within the seismic crew are all unique in what their responsibilities entail. Let’s start with the Navigation Department. A.k.a. Navigators, Nava-guessers or just Nav for short. Their main job is to keep the vessel “On-Line” as it acquires seismic data. High quality data is useless if we don’t accurately and precisely record where it was collected. They do have other duties, such as survey planning with the Party Chief, processing the navigation data after each seismic line is acquired and keeping their “in-sea” equipment ready for deployment. They are very often assisted by the “gunners.”

The next role is known as the “Observers”, “Obbies” or ACQ department. They work alongside the Navigators in the Instrument Room, Recording Room or Lab as it is called on Research vessels. They are tasked at insuring that the seismic cables and recording systems are capturing the precious seismic data. They are also found on the back deck deploying or recovering the seismic cables.

Josh explains how the air guns work to our science party during the induction

Last but by far not least the Mechanic, Handling Specialist or most commonly known as, “Gunner”, rounds out the list of seismic roles. Gunners are the mechanics, engineers and the “GO TO” seismic crew for just about everyone on the vessel. One of their traits is the ability to, “Improvise, Adapt and Overcome” any mechanical obstacle. Their main role is to maintain the energy source that is being used to obtain the seismic data. They started with dynamite and moved to air guns and vibrators. Land crews still use vibrators today, but they are much larger and mounted to large “Buggies”. Nowadays the air gun is the energy source used in marine seismic. Imagine the biggest air compressor at your local home improvement store. Now, strap a dozen of those together, charge them up and release all that power at once. (WARNING: trying this at home will likely land you in the hospital, and quite possibly the on the news.) Repeat this process every fifteen seconds or so for weeks on end. Needless to say, that activity is rough on the equipment, so things break often. The gunners are also tasked with keeping all the back deck equipment in perfect working order. The list of equipment is too varied and long for this blog. Just believe me when I say they have a lot to do on a large multi-streamer vessel. One last note with regards to the Gunner, never use this job description on any visa application!!!

Shelby shows us the ropes... literally!

I taught the science party how to make rope stretchers for "on-land" fieldwork emergencies!

By Shelby Brandt
A successful stretcher creation for our volunteered "victim" Tanner.

Like me, you’ve probably used some makeshift first aid gear at some point in your life. A cotton ball and tape instead of a band aid, or perhaps some contact solution to clean a wound. However, when living and working in a remote setting, the resources available can demand some creativity from the person providing first aid.

Northern Saskatchewan, Canada. What happens if you're injured out here?!

Picture this; you’re beginning your first field season as a geologist in the beautiful Northern Saskatchewan, Canada. It’s a fly-in fly-out camp only accessible by float plane or helicopter and you’re psyched to spend a summer off grid. One day, you and your assistant are mapping 4km from shore when suddenly, your assistant falls down a shear face. You run to their side and find they are knocked out. After several unresponsive minutes you call an emergency heli to come pick them up. There is no way you can carry them 4km to shore, and the bush is too thick for the helicopter to land where you are, but you don’t worry; you have 100ft of rope in your backpack! 

I worked in Northern Saskatchewan last summer as a senior assistant for the Saskatchewan Geological Survey. My job was to lead a junior assistant through the rocky terrain in order to map the rocks in this virtually unmapped region. In order to prepare us for the potential risks and challenges associated with working in these conditions, we were trained in Wilderness First aid by the Red Cross. During this 3-day course we learned how to make splints out of branches and scrap fabric, how to start fire with a flint stick, and many other unique skills like how to make a stretcher out of rope. 

The recipe for avoiding disaster:


To make your own rope stretcher, first you need 100 ft of rope. Lay the rope zig zag across the floor with each length about 2-3ft. At each corner you tie a knot to make a loop. You continue to zig zag your way down until the pattern is approximately the same length as the injured human, continually making knots with loops at each corner. Then you lay the human on top of your zig zag so the loops stick out by their sides with the loose end of the rope near their feet. You should put some sort of support (like a Sam Splint or board) under their head and cross their arms across their chest. Wrap the rope once around their legs then put the end through the last loop. Continue to zig zag your way back up the body by putting the rope back through the loops on alternating sides of the body.

Once all loops are accounted for, tie a secure knot. At this point, the patient should be rather secure in the net-type stretcher you have just made, however there is no way to lift it. To create a midpoint to lift from, you need to tie the rope near the left shoulder, let out about 4ft of slack, then tie a secure knot at the right shoulder. At the midpoint of the slack, tie another knot with a loop. Repeat this near the knees so you have two triangles with a loop at the top of each. Put the loose end of the rope through these loops and tie a very secure knot. You may also want to put a beaner through the loops for extra support. Now, you have a secure rope stretcher. When the helicopter comes to evacuate the patient, you can throw or pass the loose end of the rope up to the helicopter and they will be able to lift the patient up using your device.

I hope you are never, ever, in this situation where you need this skill. But the next time you need a team bonding activity or cool party trick, I’m sure a homemade rope stretcher will be a big hit.


Meet the Ship's Team! Todd Jensvold - Chief Science Officer

Science-at-sea would not be possible without the hard-working crew and technicians on-board! So let's meet some of them...



Meet Todd Jensvold, our on-board Chief Science Officer. He is the main source and manager of scientific operations on-board the Langseth. Without him and his team, there would be no data for us to collect!

HOW DID YOU GET INTO THIS JOB?
I came offshore as a “seismic helper” in the oilfield industry for Western Geophysical in 1993. My brother, Tony, was working there already and encouraged me to interview with them in Houston. I was just going to do it for a year or two.. that was 26 years ago! My first job offshore was on the Western Hercules in Trinidad. The oilfield gave me the experience and training that I bring to this job for LDEO (Lamont-Doherty) and academia.

HOW MANY SHIPS HAVE YOU WORKED ON?
I have worked on 13 or 14 different ships through the years. I actually worked on this ship (MGL) around 1995. She was a lot newer and was named the Western Legend back then. She’s been modified quite a bit since then!

DO YOU HAVE A FAVORITE PLACE YOU HAVE VISITED WHILE AT SEA?
This is a tough one. I have visited a lot of places! The last few years have been pretty cool for destinations that included New York, Chile, New Zealand, Greece, Hawaii and Alaska. I would have to say that New Zealand was my favorite place so far. The landscape was breathtaking and the people are so friendly and accommodating. I have also spent a lot of time in Brazil, Norway and India, too.

WHAT ARE SOME OF THE PERKS OF THE JOB?
Traveling to so many places is a wonderful perk. I have enjoyed working with so many interesting characters along the way, as well! LDEO is very cool because we get to work with a completely new Science Party during each unique mission. The scientists and students that make up these cruises are very diverse, enthusiastic and brilliant. We often have five or six nationalities represented on each cruise. The number one perk of this type of job is the schedule. We work for a month or so offshore and then take some time off between hitches to enjoy at home with family and friends. It’s definitely a different lifestyle than your basic Monday thru Friday, 9 to 5 type of job!

WHAT ARE THE CHALLENGES OF THIS TYPE OF WORK?
We have a small core group of technicians that make every mission happen. This ship has a diverse set of capabilities. We tow multi streamer 3D configurations for one job and the next job we may be deploying a single super long 2D streamer. We often deploy and retrieve OBS’s, too. We are constantly adjusting to different configurations, different geographical locations, different weather conditions and different groups of people. Everyone has high expectations and we want to deliver good data every time. I feel like we do a great job providing this to the academic community.

WHEN ON-LAND, HOW DO YOU SPEND YOUR TIME?
I love spending time with my family and friends, especially my two little grandkids! I am an avid mountain bike rider and like to participate in area races when I’m home. I have a little place on a lake in Minnesota and enjoy putzing around the lake and property. I volunteer at the soup kitchens and minister at the jails and shelters. A simple life.

Lending a helping hand on board

 In their spare time, some of our scientists have offered to help out with the routine tasks and activities on deck!


By Victoire Lucas


Between our two shifts of the day, we have about 9 hours of free time that we can use the way we want. During those breaks we can, if we wish so, give a hand and help a bit on the deck. Of course, we are not seamen and seawomen of experience yet, and there are some activities we can’t help with for safety reasons. But there are always ways to be useful, and here are two examples. 

Last week, with my shift mate Matthew Griffiths, we went to the emergency generator room to help with the maintenance of this engine. This maintenance is done once a week by Michael Hill (aka “Mike”), the electrician onboard. We helped Mike take a look around, check that everything was ready before testing the emergency generator: check the level of fuel in the tank, the level of oil in the generator, make sure that the vent was open etc. Mike explained how all of this works and we were able to do the maintenance following the protocol. After that, Matt and I received a very fancy diploma of “Honorary Marine Engineer” (Mum, I hope you’re proud of me). Under good supervision such as Mike’s, everybody can help! 

Another way to help is by painting the metal pieces on the upper deck. Indeed, there are many things that need a fresh new paint onboard, such as the hand rails and the cranes. We can help by painting the two coats of primer and then the coats of color paint. That way, the paint will protect those objects against the seawater and last longer. 


Morgane and I enjoying some time up on deck!
We of course have safety rules to follow: wear gloves and safety glasses all the time, and don’t go outside of the hand rails so we don’t risk to fall overboard. It is a fun activity that we can do in teams of two or three, and it’s nice to be working out there, watching the ocean. I usually paint one hour and half in the morning, and about two hours in the afternoon, this activity keeps me busy and it’s a good thing! 

I hope I will have time to paint many more hand rails before our arrival in Seattle. Now when I see the Langseth, I can say to myself “I’ve been participating in this!” and it makes me very proud.

Meet the Science Party! Dr. Steffen Saustrup

Hi all, I'm Steffen and I’m a Research Scientist Associate at the University of Texas Institute for Geophysics in Austin, Texas.

WHAT IS YOUR AREA OF RESEARCH?
I work in multichannel seismic acquisition, processing, and interpretation. I spend a lot of time in the field, much of it on ships. I also TA a field course in marine geology and geophysics each May. 

WHAT IS A FIRST TIME FOR YOU ON THIS CRUISE?
This is my first time to use two seismic sources in flip-flop mode. It’s also my first time to sail with so many people from France. 

WHAT ARE YOU EXCITED TO LEARN/DISCOVER ON THIS EXPEDITION?
I’m excited to try to image an undersea volcanic magma chamber in three dimensions. This is a really challenging environment for seismic imaging, but already our preliminary results show success. 

WHAT DO YOU LOVE ABOUT THE GEOSCIENCES?
I love that the geosciences involve so many of the other sciences all rolled into one field – I get to touch on chemistry, physics, biology, mathematics, astronomy, geography, and oceanography on a nearly daily basis. I love nature and I love history, which are what geology is all about. I love being in the field. I love forming a working team out of a group of skilled and talented strangers with a common goal. I love that geology is all around us. I love that I get to work with very smart and capable people, both in the office and in the field. I love travel, new places, new cultures, weird foods and strange money. I love boats and being on the ocean. I love working with cutting edge instruments and technologies. I love the feeling that I’m involved in important work. I love teaching. I love that what we do is not easy. I love that the people I work with – both the scientists and the non-scientists (deckhands, cooks, engineers, technicians, computer jockeys, admins, sailors) -- are all adventurers with a laugh and a story to tell. 

TELL US SOMETHING ABOUT YOURSELF!
My hobbies are music, sailing, fly fishing, dancing, cooking, and most recently painting. I’m lucky enough to have seen a lot of the world, including trips to both the Arctic and Antarctic. I’m passably good with Spanish, and Patagonia is one of my favorite parts of the world. I sort of fell into geophysics after I took my first introductory geology course as an elective, I had been a computer science major before that. Geology just plain made sense to me.
