We present a new product composed of a set of thermohaline climatic indices from 1950 to 2015 for the Mediterranean Sea such as decadal temperature and salinity anomalies, their mean values over selected depths, decadal ocean heat and salt content anomalies at selected depth layers as well as their long time series. It is produced from a new high-resolution climatology of temperature and salinity on a 1=8 regular grid based on historical high-quality in situ observations. Ocean heat and salt content differences between 1980-2015 and 1950-1979 are compared for evaluation of the climate shift in the Mediterranean Sea. The two successive periods are chosen according to the standard WMO climate normals. The spatial patterns of heat and salt content shifts demonstrate that the climate changes differently in the several regions of the basin. Long time series of heat and salt content for the period 1950 to 2015 are also provided which indicate that in the Mediterranean Sea there is a net mean volume warming and salinification since 1950 that has accelerated during the last two decades. The time series also show that the ocean heat content seems to fluctuate on a cycle of about 40 years and seems to follow the Atlantic Multidecadal Oscillation climate cycle, indicating that the natural large-scale atmospheric variability could be superimposed onto the warming trend. This product is an observation-based estimation of the Mediterranean climatic indices. It relies solely on spatially interpolated data produced from in situ observations averaged over decades in order to smooth the decadal variability and reveal the long-term trends. It can provide a valuable contribution to the modellers' community, next to the satellite-based products, and serve as a baseline for the evaluation of climate-change model simulations, thus contributing to a better understanding of the complex response of the Mediterranean Sea to the ongoing global climate change. The product is available in netCDF at the following sources: annual and seasonal T =S anomalies (https://doi.org/10.5281/zenodo.1408832), annual and seasonal T =S vertical averaged anomalies (https://doi.org/10.5281/zenodo.1408929), annual and seasonal areal density of OHC/OSC anomalies (https://doi.org/10.5281/zenodo.1408877), annual and seasonal linear trends of T =S, OHC/OSC anomalies (https://doi.org/10.5281/zenodo.1408917), annual and seasonal time series of T =S, OHC/OSC anomalies (https://doi.org/10.5281/zenodo.1411398), and differences of two 30-year averages of annual and seasonal T =S, OHC/OSC anomalies (https://doi.org/10.5281/zenodo.1408903). © Author(s) 2018.

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.
