Abstract :
[en] Since 1969, the Liège Colloquium on Ocean (Hydro)Dynamics is organised on a yearly basis and has gathered more than 3300 scientists in editions articulated around specific topics covering a wide range of disciplines and many sub-regions of the global ocean. Following the 3rd Edition (1971), the organizing committee proposed to make the Colloquium an annual event: “It is a great joy for the Organizing Committee to realize that, in the same time, the continuation of the Colloquia was deeply desired by all the participants and that their gratifying determination was indeed answerable for making, from now on, the Liège Colloquium on Ocean Hydrodynamics an annual meeting.”
The present work presents a first analysis of the data collected on
1. the number of participants,
2. the abstracts received and
3. the articles published in the special editions.
The data were processed in order to produce choropleth maps and time series.
For the most recent editions, the information was available from the colloquium websites and from the journals publishing the special issue, whereas for the first editions, the printed versions of the journals were the only source of information. As of January 2017, the information from the 1990’s could not be recovered due to the absence of participant lists in the journals and the probable loss of lists, either in paper and electronic formats.
While the attendance was not the main target for the successive organising committees since the topics were often very specific, it is worth noting a general increase in the number of participants and the represented countries. For instance, the 2013 edition, dedicated to the “Primary production in the ocean: from the synoptic to the global scale”, was attended by 220 scientists from 35 countries.
An EOF approach was used to estimate the missing values in the different times series. In particular, based on the past editions and the number of abstracts received before the deadline, we use the DINEOF tool to estimate the number of participant for this edition. The forecast value is 112 participants.
All the data and source codes are made available through GitHub (https://github.com/gher-ulg/Liege-Colloquium-on-Ocean-Dynamics), while the interactive maps and times series are displayed at https://gher-ulg.github.io/Liege-Colloquium/, with the idea that these datasets and maps will be updated every year and that more sophisticated analysis will be performed.
