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?

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 :))

CRUISES AND HORSES DRUGS

As I said in the last post, one of the things oceanographers do is going to sea on research cruises. In the maps you can see the ports I have been, either to start, finish or just calling in. In total, there are 16 cities (some of them in different cruises, some of them last several days and some of them only a few hours). Overall, I have been 227 days at sea (that means, almost 8 month of my life!).

Every cruise is different, although they have things in common:

–          They always start after two or three days of complete chaos in the harbour; unpacking and setting up the equipment in the labs on board. If you are fortunate with the equipment and the weather, this chaos will decrease and you will have a pleasant cruise (unfortunately, this does not happen too often, and you normally deal with unimaginable problems of all types).

–          You disconnect from real life: forget about money, about cell phone, about checking email, Facebook, twitter… every two minutes. At the beginning it is hard but then, believe it or not, it’s RELAXING!!

–          You are in a limited space for 24/7, with a completely different routine from normal life. Thus, special relationships are created between people on board. They are not friends (normally) but they become friends with whom you share more than with normal land friends; they are not family but they became part of your family during these days (and in some occasion, for the rest of your life because many oceanography couples begin their relationship during cruises, including mine!)

–          I always get seasick at least once during the cruise. It has improved over the years but I think it will never go away. On my first cruise, I was so bad the crew gave me an anti-seasickness suppository and I used it without thinking anything against it (I think they were military horse drugs because it worked quickly and miraculously. I still have the little box at my dad’s as a souvenir). On the other hand, the last one, in the middle of the Southern Ocean, my day of seasickness was a mixture of hangover and bad mood.

 

On the other hand, each cruise is different, a complete “Big brother season”:

–          There are one week cruises and there are looooooooooong cruises.

–          There are open ocean cruises and there are coastal cruises. In open ocean, you are lucky if you are able to see land in the middle of the cruise. This much-deserved stop comes as you step on land and feel “land-sick”. You see different faces to the ones you’ve been seeing for weeks. Along the coast, (like coastal fisheries) you normally go to harbour every night, although you’ve been working non-stop the whole day.

–          There are dry cruises and there are cruises with different bars on board. When you disembark from a dry cruise, you feel completely detoxed but the first instinct you have is to look for a beer!

–          Normally in cruises you work in shift: some are 4 hours on- 8 hours off (so you can have a “baby” shift from 8 to 12 (am and pm) or you can have the “dog” shift from 4 to 8 (am and pm); some are 12 hours on- 12 hours out. So, at the end of a cruise, a part of you has to adapt to normal life again, taking care about purse and calls, sometimes you feel a kind of rare jetlag.
