Old Weather

The Old Weather project launched in 2010. It is a web based project in which members of the public volunteer their time to help climate scientists by transcribing weather observations written in historical shipping logs recovered from archives around the world.

We spoke to two highly active Old Weather contributors – Helen J [OW_1] and Joan Arthur [OW_2] – and two climate scientists that were involved in the project. We also spent time exploring and analysing the online forums that the community of volunteers use to communicate with one another.

Once you have finished follow the blue line to Met Office on the right. Here you can read more about how Old Weather contributes to climate science in the ACRE section of the Met Office R&D tab. Or, if you are interested in finding out more about the historical shipping logs that the volunteers are transcribing follow the blue line on the left to Archives.

Data Journey-0

The Zooniverse platform

Digitised ship log books are loaded onto the Zooniverse online citizen science platform, ready for transcription by Old Weather citizen scientists.

The records are organised on the website in a small number of projects, for example Royal Navy records for 1914-22. In each project, the records are then organised by ship, and for each ship there might be a number of different voyages over a period of months or years.

Transcribing the log books

The Old Weather project’s citizen scientists select a ship and voyage to work on from those currently available, and then begin transcribing via the Zooniverse online platform. By the end of the first phase of transcribing Royal Navy log books in 2012, Old Weather volunteers had recovered around 1.6 million weather observations.

Watch the video below from the NOAA (National Oceanic and
Atmospheric Administration, USA) to find out more.

The volunteers are free to choose which records to work on. Some people base their selection on having a personal interest in the ship or geographic region. Other reasons for selection include more practical concerns such as the ease of transcribing the sailor’s handwriting, or the need to complete a particular section of the project – for example, ensuring a series of records is fully transcribed:

This one really I just kind of landed on accidentally, I think I quite liked the picture of it to be honest, which was not a scientific reason at all.  And the writing didn’t look too bad, and so I kind of got on it, and now I feel sort of responsible really, particularly because of this very, very long one, and nobody much seems terribly interested.  I mean it’s been done by one person all the way through.  He’s done the full lot.  I’m the second person going pretty much all the way through, and then we’re going to have to try and persuade somebody else to do the third, or various people to come on and do, you know, and do a bit.  So yeah, so I feel kind of responsible in a sense. [OW_1]

Once the volunteer has selected a record, they view the digitised logs on the website and transcribe key information into a simple online form. The type of information that they transcribe includes: date, time, location and the various weather observations such as temperature and humidity. An example log book page is shown in the image below:

Transcription challenges

Transcription can be a difficult task. The main challenge is deciphering the handwriting in the log books. There is significant variation between sailors – some having very clear handwriting and others an illegible scrawl.

Other challenges are decoding some of the words used in the notes section, and identifying place names accurately. Volunteers often turn to the Old Weather forum for help with these issues, posting snippets of log books so other volunteers can take a look and offer assistance.

Editing historical information

Written notes made by sailors about the weather and aspects of life on-board the ship are also optionally transcribed by some volunteers.  Information captured in this way might include notes about on-board cargo, supplies, deaths of crew members, and even personal notes and doodles.

Once a log book is completed, these extra notes are edited by volunteers to remove duplication and improve consistency. These transcribed notes are useful for climate scientists to understand more about the context of the observations they are using, but they are also used by other researchers. Much of the historical data is uploaded to Naval-History.net so it can be accessed by professional and amateur historians.

Whilst the editing work is often more interesting, there is a certain level of responsibility and importance attached to transcribing. Transcribing activity was viewed as more important than editing in terms of volunteers supporting the needs of climate science.

I suppose at the moment I probably find the editing more satisfying.  But I feel the transcribing is more the point of the whole thing. As I said, when I wasn’t transcribing I did feel a bit guilty.  So at the moment I’m doing both, and I tend to alternate, you know I’ll do a day or two of transcribing and then a day or two of editing, and so on.  And that feels like a reasonable balance. [OW_1]

Quality control

To avoid transcription errors and the potential for manipulation of the data, each entry is separately transcribed by three volunteers. After transcription has finished the data is checked for accuracy and consistency, before being sent to the Met Office.

Sharing the data

The transcribed data is then standardised into a format called IMMA (International Maritime Meteorological Archive) and integrated into the International Comprehensive Ocean Data Set (ICOADS). From ICOADS the Old Weather data can be accessed by climate scientists around the world.

As climate scientist Philip Brohan explains, these Old Weather data are used in at least five major climate reconstructions including 20CR Version 3 (NOAA/University of Colorado), Era-Clim (ECMWF), SODA (Texas A&M), HURDAT (NOAA) and HadISST2 (Met Office).

Culture-1

Making a contribution

Since the project began thousands of people have made a contribution to the Old Weather project. Researchers from UCL have conducted in depth research about the motivations of these Old Weather volunteers.

Many of these contributors have made a small number of contributions, however there are a core of highly active volunteers who have been engaged with Old Weather for a number of years.

The Old Weather volunteers that we spoke to demonstrated a strong sense of social responsibility, and a desire to make a contribution to climate science through their work on the project:

I’ve got a concern for the planet, you know, and the way that we treat it and so on. And so actually doing something that was in some way going to contribute to that kind of research attracted me. That was definitely the initial thing. I was thinking this is an amazing source of information, you know, all these logs, but there’s no way of getting at them unless people get in there and do it because computers can’t read the writing. [OW_1]

I mean to my mind the name of the game is trying to find out what’s going on with the climate. [OW_2]

I’m trying to do my bit [for climate change]… when I wasn’t transcribing I did feel a bit guilty. [OW_1]

Volunteers took pride in the quality and accuracy of the  contributions they made:

The handwriting varies enormously…that’s definitely one of the main frustrations is just trying to decipher what it is, and trying to make sure, particularly with the weather records that you’re as accurate as possible. [OW_1]

Recognition

We observed on the forums that volunteers responded enthusiastically when their contributions were recognised by climate scientists, for example when climate scientists talked about specific projects that were using their data.

One post from a volunteer reported a recent teleconference at which a number of well known climate scientists said “some wonderful things” about the Old Weather community. Their work was identified as being “extremely helpful to data analysis” and making climate scientists “job[s] very much easier”. The project as a whole was identified as having “changed world-wide perceptions of how to recover old data in many fields” and the volunteers were told that they “should be very proud of what [they] have achieved.” The forum community was very pleased to hear their work was so appreciated and useful:

It helps to get you through the inevitable tedious bits to know that the work is appreciated and used by the experts. (#2)

Sometimes you wonder what’s happening to all the work….then you get a report like this and you KNOW what you’re doing is right. Thanks so much for this report…and to all the others in the system that we rarely see/hear from. ;) 8) ;D (#3)

Thanks for sharing this, Janet.  It’s great to know that what we’ve worked our way towards has really changed perceptions of what volunteers can achieve (#4)

WOW! I knew our work was useful, but I didn’t know it was THAT useful! (#6)

Productive leisure

The core contributors we spoke to both had free time that they were able to dedicate to leisure activities. The Old Weather project was perceived by them to be a productive form of recreation to engage in:

I mean it tends to be something I do in the evening when I’m listening to the radio. It goes very well with Radio 4…So I’ll do that and I can be doing something, you know, sort of productive at the same time. So it’s basically a sort of leisure time activity… it’s not just purely you know, passing the time if you like…it’s contributing something useful, but it’s also interesting and educational, and you know, kind of community building and, yes all sorts of things. [OW_1]

I thought, do you know I’ve been meaning to do some citizen science for a long time, just on the basis of, you know, there’s a computer sat at home, it’s doing nothing, I have some spare time. Well, you could probably call some spare time, why not give it a go. [OW_2]

Community

The Old Weather project online forum acts as a community hub where members of the project congregate to discuss and find humour both in their Old Weather transcribing and their wider lives:

I think it’s quite a remarkable place, and I think it’s probably quite a large part of what keeps most of the hard core interested and whatever. You know because it’s not just you sitting at your computer in isolation transcribing away, you know it’s also actually relating to other people who are doing it. [OW_1]

It’s really nice to know that there’s somebody else out there who kind of cares for you as part of the party.[OW_2]

In the chat thread someone has just announced the birth of his first child, for example, one of the transcribers [laughs]. And we have that quite a bit you know, people are telling each other about important things in their lives, or that they’re going off on holiday so they won’t be around for a bit, but they’ll put some photographs up when they come back, and this kind of thing. So it’s got a real kind of community sense, as well as being a very useful source of can anybody read this writing, does anybody know what’s happening here. [OW_2]

The community was also enthusiastic about publicly recognising one another’s contributions. The quotes below are a series of posts on the Old Weather Forum in response to the publication of a blog post written by community members:

Good job, you two. (#390)

Wow :) Job here lots of hard work. Way to go everyone! (#391)

Impressive job combining all those logs! (#392)

Great job! (#393)

Tour de Force – congratulations to all involved. It is a great blog. Brought a tear to my eye. (#394)

…Thanks for collating the logs. (#395)

I did love the way Caro interweaved the 9 logs.  Impressive.   (#396)

Wow, this is both impressive and fascinating… (#397)

Brilliant bit of weaving together the logs.  (#398)

Historical connection

For some of the volunteers it was the historical context of the data they were transcribing that captured their interest and motivated their daily work on the project. Some of the Old Weather volunteers experienced a strong sense of connection with the crews of the ships taking the observations they were transcribing:

 

I mean on one of the ships I was on…the number of the sick list kept going up, and of course it was the influenza epidemic. And I remember realising that I was really quite anxious about this ship and this crew…And I was thinking this is silly, you know, this is all a very long time ago, whatever’s happened has happened. But I realised I was really getting quite anxious about my crew, and you know, hoping that they were all going to, you know, having come through the war that they were actually going to come through the flu epidemic. [OW_1]

I’m very moved by the fact that having battled to sink the German ships, they then go all out to pick up survivors. (Contribution to the Old Weather Forum)

Vulnerability

Whilst the Old Weather community is strong and their work is recognised as valuable by many climate scientists, members demonstrated a keen awareness of the project’s vulnerability. Relying on voluntary labour means the project is dependent upon keeping the intrinsic motivation of participants high. The factors discussed above contribute to this process, however there have been periods in the project’s history where this motivation has been lower. For example, when the project shifted from transcribing Royal Navy ships to American vessels and lost a lot of volunteers.

 I think we were on a knife edge at that particular moment, it was very scary. We did lose a lot of people who decided that actually, the whole thing meant so much to them that to cut and run was probably the only sensible way to deal with it. And there’s people like me who actually can’t imagine life without it…And somehow we got ourselves through that, and I mean I realised early on what we’d done, and I think then it was a case of everybody trying to be as jolly as they could, keep the things goings, lauding the work that we were doing so far. Picking up interesting things from the American ships to try and make them look as interesting as the Royal Naval ones had been. [OW_2]

Despite this vulnerability, the Old Weather project holds strong and the volunteers continue to make a significant contribution to climate science.

  1. It is really impressive of what the Old Weather project is trying to do – to understand and comprehend how people in the past record and investigate weather patterns. The most exhilarating part is that most participation is voluntary and how the projects influence community to research on the profound history.

  2. This is a fascinating project, but I feel that the complexity and value of the work that the volunteers are doing should mean that they get some form of payment for their time and hard work.

    1. I disagree – I should not be prohibited from adding to the world’s knowledge of climate because they don’t have the funds to to pay me. I deserve the right to give freely to any worthwhile project. Besides Citizen Scientist projects, churches and charities also benefit from many good people wanting to give time and effort.

      1. Joh, and if you felt ridiculed and talked about by them when they went away, oh, yes yes, you im sure were. saudis are A1 first class when it comes to riiucildng, judging, making fun of to no end. they have no empathy..i know this. take no effence, they cant help it and really dont realize themselves

      2. In relation to availability, in one of my previous communications with Mr. V.K.Gupta, he mentioned that -there seems to be general opinion that TKDL with safeguards can also be made accessable to public funded National R&D institutions subject to the approval of Govt. Maybe we can find that coming up next in some time.

      4. how can anyone be offended by the cartoon of the words we are force-fed every day? “there is no daylight between us”, “no closer friend”, “the close relationship”…if everyone is already thinking of the picture EVERY TIME they say these things, why does it take so long for someone to draw it?and while you’re at it, the “standing ovations” sounded like “standing erections” to me.

      1. What a great site indeed comments content news constantly up to date and quit,lyathis site now and much faster high-quality and fast site that comments are always up to date, admin really want to thank us, it's thanks to such a beautiful site comments we gain knowledge we and listen from this site music

    2. It's not even that it takes 2 seconds it's the fact that Youtube just forced it on us with no way to turn it off by default. They could have used their time to improve on other things.

    3. Ask them to read a poem or something during the ceremony.. give them a special mention in the order of service.. ask them to make a speech/raise a toast at the reception. If any of them are musical ask them to play a piece at the ceremony or dance, party piece etc. at the reception. Escort your mother to her seat if your father is giving you away. The possibilities are endless!

I’m not sure whether this post is written by him as no one else know such detailed about my problem. You are wonderful! Thanks! your article about The Time to Buy Gold and Silver Is When There Is Blood In the Streets | preciousmetalsnow.netBest Regards Agata

    7. okt13 I’m impressed, I should say. Actually rarely can i encounter a weblog that’s both educative and entertaining, and let me let you know, you can have hit the nail for the head. Your thought is outstanding; the difficulty is something that not enough persons are speaking intelligently about. I am very happy i stumbled across this during my seek out some thing with this.

    1. Since I began reading this I have been nothing but enrdetainte, impressed and interested. Your talent shines through this whole article. You really know your stuff. You should really keep up this kind of writing.

    2. Herman was in Amsterdam vaste klant bij Van Beek Graphic art supplies. Het moet in 1979 geweest zijn. Herman stormde binnen op zoek naar een spuitbus cocacola-rood. Mijn vriendin was verkoopster bij Van Beek en hielp de half kleurenblinde Brood daarbij. In het kielzog van Herman was ook Nina Hagen binnengekomen. Terwijl Herman op zoek was naar zijn rood, stond die Nina zich op te maken met uit de rekken gestolen kleurmarkers.

  3. This really makes me appreciate volunteers and citizen scientists — their contributions should definitely be more recognized within the scientific community… Science doesn’t and shouldn’t limit those who are interested.

  4. As an oldweather transcribers for about 3.5 years I am deeply glad that we have no payment – it keeps the whole think as altruistic as possible, and prevents money becoming ‘mammon’ within the scientific purity of the project

  5. I’m very happy not to be paid – it would change the whole ethos of the project. And I feel that we are appreciated by the scientists; their presence on the forum and engagement with us, answering our queries, and responding to suggestions for improving the interface, all make it feel like a very collaborative project.

    1. Maybe the complete OED? And then a few crossword puzzle books-because with such a stellar and improved vocabulary surely cross words would be a piece of cake! I still say if I could take only one book to a desert island it would be Dumas’ The Count of Monte Cristo (it’s got a little of eve1uthing)&#82r1;ynabridged of course.

  6. This lead question caught my attention: “How do you think the cultural values of the volunteers might impact upon the production and quality of the data transcribed by the Old Weather project?”

    It doesn’t – numerals and letter codes cross language barriers and have no cultural aspects. Likewise judging the shape of galaxies and the number of penguins visible. The transcribing or recording of data is remarkably clean and clear, unlike the later analysis of the same data when you are choosing what questions to get answered.

    1. Can I achive notes for 2012 exams in hindi medium by vpp? if not; then plese guide me. I have no enough money to go to Delhi for preiapring exams or to achive notes. plese help me.
