Little eco-gestures

It has been super long time since I’ve written a post in my blog. It has been a crazy summer for me: hen-do party in Madrid (yes, scientists also party hard J), University friend’s wedding in Puerto Real (where I was first made!), preparation for cruise (not only normal packing preparation but also getting catamaran and buoy ready for the first ever real deployment), visitors at home for a week, cruise in the Baltic Sea for four weeks, holidays in Ibiza for ten days, SOLAS conference in Kiel for a week (where I co-chaired my first discussion session). I can write a post for each of this points (I will definitely do for the Baltic Sea cruise) but today I want to tell you about something different.

By now all the readers of this post know I work with CO2 in the ocean. During more than 11 years I have been actively working on this, I am often asked the question/comment along these lines; “you study CO2 but you cruise the Polar oceans” or “a lot of CO2 problem but you go to a conference in Hawaii”. Although cruises are still necessary to understand the complexity of our ocean, the oceanography community is investing a lot more effort in the “environmental friendly” platform like Argo buoys, fixed platforms with automatic sensors, gliders… Also it is also necessary to meet with your fellows in conference for networking, plan future research… However, more and more video-calls and conferences are used to discuss plans and papers.

But today’s post is about the personal little actions one can do to contribute less to the carbon budget. Of course you don’t need to be a carbon expert to do that but for me it makes more sense to be as consistent as possible with my life. I have a car and a bike and I try to cycle four days per week to work (believe me it is not always easy in North-Germany for a Mediterranean island girl). The fifth day I use the car because I go from work directly to a German course with my husband. We don’t use plastic bags for shopping and we avoid buying products with lots of packing (my friends, bananas have the most clever natural way of packing themselves, they don’t need an extra packing!). I do not use disposal tampons or slips but silicone cup and clothes washable slips (also these super white products are not really healthy). I always used alum deodorant, clothes tables napkins..

I don’t buy a lot of clothes, with travelling I learn we really don’t need that much to live comfortably. I admit I’m a fan of the charity shop (my angry aunties say I wear death’s clothes), where you give a second chance to a lot of things that otherwise would be waste. I had strange conversation with the cell phone customer service department who tried to reward me with a new cellphone because I’ve been such a loyal and good costumer: “No, I don’t want a new phone, mine is working fine” and the lady repeated again and again with surprise “but madam, it is free, you don’t even need to pay the delivery service”.

Sure I miss a lot of other little gesture one might do to reduce the impact of CO2 footprint. What are yours?

THE BUOY IS FLOATING!!

After 5 months from the start of my new job in Germany, we had our first sea trial of the buoy we are building to measure CO2 flux. The whole process was really quick, mostly because of the great job of the workshop folks; if it was me alone, I would still be trying to figure out how to put two aluminum sticks together 🙂 So that’s a good example how oceanography is a team game.

So everything starts when I learnt that one main task in my new contract is to help build this buoy. As always, first doubts of “Will I be able to do that?” now more emphasis with my less than beginner German. But it turns out that language was not a problem: a little bit of German, a little bit of English and A LOT of WILLING to communicate with each other.

Every visit to the workshop was full of excitement: “What am I going to find new?” I was in beginning to see a little baby growing :). One day I arrived at the workshop thinking it will be one short visit to discuss one small item but I spent almost all my working day with them… that was serious! They want it done soon and when they have the time for you, you don’t waste the opportunity.

A cold morning in January we went, buoy up to a trolley, buoy up to a crane, buoy down to the sea!!

OMG just before that, all the doubts again: did I close the sensor properly? Have I forget some connection? Was the time configuration right? Will it float?

It turns out to be a success, not only the buoy floats but it also measures what it is supposed to measure 🙂 . So next step is to build an arm to move an instrument that measures current in and out of the buoy, attached some temperature sensors and GPS. By April we hope to be doing our first real measuring day, you will hear details soon 🙂

I SURVIVE 5 WEEKS WITHOUT SEA (A RECORD FOR ME!!)

It’s been a while since I have written in the blog but I have a good excuse, I was in a 4 weeks experiment in a circular wind tunnel in Heidelberg. 4 weeks plus preparation and installation of all the equipment plus take everything back to our home lab means A LOT OF WORK!! Some of you may not know where Heidelberg is (I didn’t the first time I heard about this experiment). Here is a map of all the places I have been during this adventure or I talk about in the post: mapHDhttps://www.google.com/maps/d/edit?mid=zR6f-Im6yd2U.kQUx9OZrrsbA

So, the second obvious question is “Why an oceanographer works during more than 5 weeks in a place 500 km away from the nearest sea water?” Not only that but also you’ll be surprise to know that we actually work with seawater! It is a big interdisciplinary project call SOPRAN (http://sopran.pangaea.de/). They collected water in the middle of the North Atlantic from a research vessel, transport until Kiel where they transfer to a track (whose next transport after our seawater was gums from bear gums, like haribo, so if you taste some salt in the last sweat, do not be surprise, hahahaha). So, that’s the explanation of how the water arrive to Heidelberg or the so call “Heidelberg ocean”. So in theory, I haven’t been without sea the whole time

Next obvious question, why so many bothering to bring water to Heidelberg? So at University there, they have a circular wind tunnel facility. That’s a 10 m diameter ring that you can fill with 1 m water (that means 18 m3 of water, 18000 L; that means if you have a big bath you can fill your bath ten times with this water!!). So this experiment was the first time they fill the facility with seawater, before they only use tap water or destilled water… Of course, seawater behaves different that freshwater so that makes this experiment so important. Ok Mariana, ok… a lot of blablabla but you haven’t explained yet why this is important.

So what we were trying to quantify is the flux between the water and the air of different gases and how this flux is affected with different factors. Some of the readers will get lost with this explanation but I have a good example everyone will understand. Imagine you are in a party with two rooms separated with a door. Originally all the people are in the first room but then more and more people arrive so people start to occupy the second room. Then you have more or less the same number of persons in both rooms, but this doesn’t mean people don’t move, you can see a friend in the other room or a plate of biscuits you like. Sometime the door could be lock or really heavy so really difficult to open and go through. Some other time the door can just blow out because of a lot of wind. So the two rooms in our “party” are the water and the air inside the tunnel and the door is the interface, the surface that separates them. This door (interface) can be heavier or not depending on the wind speed, the waves, the surfactants… so some people (gasses in the tunnel) may fill more comfortable in a more empty room or some prefer the warm to be with a lot of people (depending on their solubility and the temperature in the water and in the air).

I hope my example of the party help you understand the beauty of the air-sea interactions. Of course real live is much more complicate, there are gasses (and people) who doesn’t like others, there’s people who combine closely with other people…

We spent long hours in the lab (some days more than 16!!) but I always try to find some time to explore the surrounding area. So Heidelberg is a really nice and lively city. We also visit the Black Forest and Bern during different free weekends.

Overall, the experience was really good, I met a lot of nice people and we have a lot of interesting data (that will keep me really busy in the next months!!) but I have to admit that oceanography cruises are more fun. First, you don’t have to worry about the logistics of food, shop and accommodation (after 16 hours work, the only thing you don’t want to do is cook dinner!). Secondly, there’s no call to see polar bears, penguins, whales or albatross from your cabin window. All you see is workers in a new building (and that does not change everyday :))

SCIENTIFIC WRITING FOR DUMMIES

Some weeks ago my first postdoc paper was accepted. Some of you might be familiar with what a paper is and what is mean “accepted”. Today´s post is for those of you who are not.
So after you come back from a cruise and analyze your samples, one has a huge amount of data to organize and graph. Then comes the funniest and more difficult part, writing stories about what’s going on in the field/experiments. Let’s say it is like, “Once upon a time…” but with scientific writing and structure: Abstract, Introduction, Material and methods, Results, Discussion, Conclusion, Acknowledgments and References. I should say this is the part I find more challenging; when I am starting a new paper, it takes me forever to speed up my typing. Some weeks are 0 words and at other times while revising, everything written before is deleted which equals negative writing speed.
However, suddenly, a good idea lights my brain, and then another and the words flows without effort. Once you have the structure, the main message, the main character (in my case it is normally CO2 with its different outfits) and an end, you send to the co-authors (people who participate in the same project, your bosses…). After this stage, I have different experiences: sometimes some co-authors do not bother to read, some flick through and pick typo mistakes, sometimes they disagree with the structure itself (and you have to reinvent your story) and others nit-pick the little details and the manuscript that returns has more of his/her works than yours. After some toing and froing with your co-authors, you send the manuscripts to a journal. You choose the journal depending upon your subject, the importance of your work, your past (or your boss) experience, free or open access…
Once submitted, you wait for the editor’s response. If the editor thinks the subject or the quality of your job is inadequate for his/her journal he/she rejects it immediately (that case never happens to me!) What the editor normally does is send the manuscript to different referees (expert in the area) who may agree to comment on your work. Of course, when you are in the play, you will be asked to review other authors’ papers (I still remember how happy I was after I received my first invitation! But now it starts to be too much work).

These referees can choose to be anonymous and a few, under the anonymity umbrella can be really rude (I have one in a paper from my PhD who even started writing in capital letters like he/she was shouting at me!!) They can be, like co-authors, skimming or diving through my work. Normally, one receive constructive comments that greatly improve your manuscript. These referees make a suggestion to the editor: reject, invite to submit again, major changes, minor changes or accept as it is. I have always had to make adjustments. Again, you modify your manuscripts according to the referees’ comments and send back the manuscripts. Some referees ask to read the manuscripts again and at other times the editor makes his/her own decision.

It’s like a tennis play, you fight to get the ball to the other end against co-authors, editors, referees and it takes a lot of back and forwards until you succeed.
After so much effort and pain (and time, the whole process can take more than a year), you can imagine who happy you feel when you received this email:

Email informing about acceptance of my last paper

I received the email confirming my first accepted paper when my partner was in my office and in the attempt to embrace him, I was so excited that I erroneous bit his head, hahahaha… now we always laugh when I tell him I have another acceptance, he always answers: “Congrats my darling, should I need to put on a helmet?!”

Helmet and papers :)

To travel without money, sailor (or scientist)

There have been few weeks I haven’t upload a map in the blog so this week I thought I will talk about conferences, or “scientific travel”. These are different from project meetings (see post “What oceanographers do”), not all the people work in the same project. Some conferences host a small number of scientist and some are huge (the biggest I have been was this year in Hawaii and we were just under 5600!!). Some are really specific (for example, focus on calculation of a constant the control air-water interchanges) and some are really general (Ocean Science Meeting: http://www.sgmeet.com/osm2014/).

I have to admit that (mostly during my PhD) the decision to go or not to a conference was more dependent upon where the conferences were held than on the scientific content. There is a phrase in Spanish that says “para viajar sin dinero, marinero” that means “to travel without money you should become a sailor” so we have to add scientist to sailor. Well, at least with less money, so what I normally do is stay some days before or after the conference visiting around. I convince myself that it is good for my CO2 foot-print, it’s not worth travelling to the other end of the word just to be inside a dark room or conference building. The last international conferences I attended, I invited my dad to join me so we could enjoy holidays together, otherwise it would be really difficult to organize. He is my best judge when I do my presentation, even if he has no idea of English.

European Conferences

European Conferences

In total I have been to 15 different cities because of conferences (some cities, like Gran Canaria I have been twice). There are some conferences that you are unable to attend but some colleague can. So, you send your poster with him/her or he/she presents a work you have done together. Even if they are in my CV, I will not put these on the map because I haven’t been there physically.

Non European Conferences

Non European Conferences

One big part of what we do during a conference is similar to project meetings: room/coffee/room. Another important part of the meeting is poster sessions. When you have a poster, you arrive with your big printed poster; not all the people you see in the airport with poster tubes are architects. Although lately some conferences offer you the opportunity to print on site or you can print in textile so you transport your poster like your t-shirts. Then you located the spot you have been assigned to display your poster and in the time you’ve been allocated, you stand in front of your poster hoping someone will stop by and discuss your work. Most of the time you have really nice discussions with other people, because the clock is not pushing against you like in a presentation and you are normally more relaxed with time to talk one-one than in front of an audience (except if this one is a big fish, then your heart rate also speeds).

Finally, another important thing to do during conference is networking: you try and talk with people in whose work you are interested (and match a face with a famous name you have been reading a lot!). Or because you are interested in working with them or have been reviewing some of their work… If this talking can be with a beer (or two) and as an early career move you manage to impress this person that they remember your face for the next conference, you have been successful (or they remember your name, that will be even more of a success).

What oceanographers do on a day-to-day basis?

One thing I most like of my job is that it has a lot of different task for example:

  • Conferences
  • Meetings (with the boss, with students, with colleagues, with people in the same project…)
  • Cruises
  • Courses
  • Lab work
  • Data analysis and treatment
  • Writing
  • Revise (your own work and other works)
  • Apply for new jobs, new fellowships, new grants…

The problem is that this variety doesn’t happen every week. When I am on a cruise, I am on the cruise for several weeks, 24/7 (and towards the end of the cruise I dream of being at my office desk and my sofa). When I am finished with the cruise, I have a more normal office life (although occasionally, a lot longer hours), and after several months of being in front of the computer I dream on going to sea again!!

In my blog I would like to tell what I do during my days in England. Today I will start with an end of project meeting which happened this week.

My contract is associated to the Sea Surface Consortium (http://www.surfaceoa.org.uk/) of the UK Ocean Acidification Research Programme (http://www.oceanacidification.org.uk/). That means, among other things, that one works and interacts with a lot of people from different institutes. Even in the internet era, all these people have to come together to present their results, discuss what to do with them, split tasks…

So for that reason, during the two years and almost a half that I have been working in this project, I have been to Exeter, St Andrews, Plymouth, London and Southampton. It’s a pity that because most of us are based in Southampton, we have repeated it for at least three meetings and I miss the opportunity to visit Cambridge or Obam.UKOA Cities

So we meet together and after the “hello, how have you been?” “Not too bad, thank you! And you?” we spend some hours in a room doing presentation (most of them prepared the night before in a rush and “saying oh my gosh where is this graph??!!”). Each of us talk around 10-15 minutes and then there is time for questions, comments, feedbacks. Then we break for coffee, tea and biscuits. And the chit-chat continuous: “how long is your contract for?” although some other conversations are more in detail. We reconvene and continue presenting and talking. After a couple of more hours, we stop for lunch. Then again inside the room/coffee/room and at the end, your head it’s so full of new information and new ideas of, try this, try that… that all you want it is a nice break. We have normally a group dinner in a pleasant restaurant. I believe science advance more with a beer in hand. These types of meetings are normally one day and a half or two. So the second day is where, having shown what we have done, we sit down and decide what is left to do and who (and when!) will do what. It is also the time to decide where and when to meet next.

Ribas Ribas

My name is Mariana Ribas Ribas. Hold on, wait a minute… is that your name, double it? Yes, it is. It’s not a spelling mistake with my name, it is my brand! My first and second surnames are the same. In Spain and Mexico we don’t change surnames when we marry (and sure other countries but I only speak for what I directly know), so you always have the same surname, normally the first one from your father and the second one from your mother. So, here it comes the second question that I normally get: so are your parents related? No, they are not. We are from Ibiza and Ribas is a very frequent name. Furthermore, we spell it different from the rest of the peninsular Spain, with “B” instead of “V”. So, since I left home and lived in the main peninsula (for 11 years!), I had to say everytime, “Ribas Ribas with a B”. “And the other”, they ask? “Ribas, also with B!” So then, I moved to the UK and again I have to answer for the spelling; why I have two and why they are the same.

One of the funniest moment about the double surnames was when the Technical superintendent of the School of Ocean and Earth Science, University of Southampton, where I now work, triple checked with IT that that was my correct name and he was still afraid when we put my name on the door that it was a mistake (as my office mates also thought J)

Then it’s my signature, it is Mr2. It´s not mister 2, it’s not that I’m an Einstein´s equation (not even close), or I love math (although I do). It’s m r squared. It is just an easy way to sign. And then it turns out really convenient for my logo because I work on CO2 in the ocean so I can use the 2 for both.

Mr2

I’m sure I lose you when I said where I come from. It’s always happened to me. This will come in another post…
