We invite you to book your accomodation as early as possible.

The Crowne Plaza Toulouse is located in the heart of the pink city on one of the most beautiful squares in Europe, the Capitol. Our hotel is one of the most prestigious hotels in the city just 15 minutes from the airport. From our hotel, visit the basilica St Sernin, the Augustinian museum, the convent of the Jacobins or enjoy a stroll along the banks of the Garonne and the Canal du Midi.

With its prime downtown location close to Place Wilson, Place du Capitole and Place Saint Georges, the 4-star Mercure Toulouse Centre Saint Georges hotel is the perfect place to stay in the Pink city. Looking for a relaxing stay? Whether you want shopping, culture or tourism, the hotel is the ideal base for exploring Toulouse. Traveling for work? Take advantage of the attractions in the downtown area and benefit from many transport connections for your meetings: metro, tram and airport shuttle.

With its listed building facade, the Citiz Hôtel has been changed into a boutique-hotel.
Now inspired by design, contemporary furniture, chocolate, cream and mauve tone, like an implied reference to the “ville rose”, mauve being the main theme of the hotel decoration. 4 stars property in the heart of Toulouse, the welcome is one of the priorities of the Citiz Hôtel with personalized services. At the Citiz Hôtel, the attention to detail makes the difference.

Ideally located in Place Esquirol in the very heart of the city, “Le Père Léon” hotel enjoys an exceptional position in the historical and cultural heritage of Toulouse.

The Hotel Albert 1er is located in central Toulouse, 100 meters away from the Capitol, in a calm and pleasant neighborhood. At Hotel Albert 1er, our breakfast formulas labelled ‘Tradition et Bio’ are made up of a selection of products from the Midi Pyrenees region. The Albert 1er Hotel is the first Toulouse hotel certified European eco label.

The Capitol Hôtel is a 19th century private mansion, full of charm and with a design decoration, object of constant care, to offer you the best of the art of living in Toulouse. A privileged location, just a minute walk from the Place of the Capitole, in the heart of entertainment, the hypercentre, shops, restaurants, theaters and museums.

Nigel Butcher – Senior Technical Officer in RSPB

The Argos tracking system has been used in avian ecology for many years now and the RSPB has benefited from it on a number of different projects. Our work although primarily focussed on species in the UK and UK Overseas Territory (UKOT’s) does also involve work globally.

In my role that I have held since 2000 as Senior Technical Officer within the Centre for Conservation Science I recommend and develop technology to achieve our conservation goals. Understanding the needs of species through research and protection are key areas of my work and satellite PTT’s have been integral. In recent times I have become more involved with the interrogation/analysis of the Argos data. This fascinates and challenges me as accurately understanding the results is essential to our work. I will discuss 3 tracking projects that the RSPB have undertaken: Sociable lapwing, Hen harrier and Turtle dove and highlight some of the success we have achieved with these species.

Mads Peter Heide-Jørgensen – Greenland Institute of Natural Resources

Mads Peter Heide-Jørgensen has been working with marine mammals in Greenland since 1982. He works with ecology of whales and is especially known for his expertise in development and best practise on deploying whales with satellite transmitters during the past 3 decades.

Some of the most intriguing questions about migrations and natural behavior of marine mammals are focused around Arctic seals and whales. Animals that are widely dispersed in inaccessible areas and that only in brief seasons can be observed in their natural surroundings. Naturally these species have also been targeted by some of the largest efforts for data acquisition through satellite telemetry using CLS Service Argos. Most of the 1990’s was spent on developing instruments that could meet the requirements for use on marine mammals, with the development of a very fast salt-water switch being a turning point for tracking animals that only briefly appear at the surface of the oceans. Major insight into critical biological questions were emerging after 2000 with successful instrumentations of large numbers of marine mammals with tags that provided data for months and sometimes years. Critical habitats and migratory corridors have been delineated, exposure to anthropogenic activities revealed and sensitivity to climate perturbations has been assessed. New possibilities for using instrumented animals for environmental sampling are emerging where data can be used for long-term monitoring of oceanic conditions.


Dr. Francisco Alemany – Coordinator International Commission Conservation Atlantic Tuna

The ICCAT Atlantic Wide Research Programme for Bluefin Tuna (ICCAT GBYP) started with electronic tag activities on Atlantic bluefin tuna (Thunnus thynnus) in 2011, when first few pop-up satellite tags were deployed. The main objective of this tagging programme is to unveil Atlantic Bluefin spatial patterns in order to determine the mixing rates between the Western and Eastern stocks of this species, the first spawning in the Gulf of Mexico and the latter in the Mediterranean, respectively, but overlapping in Atlantic Ocean foraging grounds, which is crucial for a proper evaluation and management of this emblematic species.

Over the course of 7 years, up to 2017, within the framework of this Programme, or in joint actions with other institutions (WWF, IEO), more than 342 electronic pop-up tags have been deployed in different areas of the Mediterranean Sea and the Eastern Atlantic. All these pop-up satellite tags were supplied by Wildlife Computers (models Mk10-PAT and MiniPAT) and all collected data were transmitted via the Argos satellite system. For the purpose of estimating bluefin geolocations and movements from tag data, all available datasets were processed using best available CLS algorithms. In 2018 ICCAT GBYP plans to continue with tagging activities, by deploying 60 pop-up tags in several areas of NE Atlantic, from Portugal coasts to Norwegian waters.

Brendan Godley – Professor of Conservation Science, Strategy Lead #ExeterMarine

Brendan has been involved with ARGOS related activities since attaching his first PTT’s on nesting green turtles in Cyprus in 1998. Through collaborative work with students and a wide range of partners, this has extended to published tracking work on sea turtles in over 15 countries as well as some multinational metanalyses and to the tracking of sharks, seabirds and fisheries. Underpinning all of this work is a natural curiosity to unpick the hidden life histories of marine vertebrates and use the knowledge to inform conservation efforts, including increasing environmental awareness.

Michel Sarthou – Argos Project Manager in CNES

In the late 1970’s the Argos Data Collection and Location System was conceived by engineers at the French Space Agency. Dedicated to the environment and begun as a cooperative program among CNES, NOAA and NASA, joined now with EUMETSAT and ISRO, the Argos success story has spanned more than three decades.

Argos Project Manager at the French Space Agency since 2005, Michel coordinates all aspects of the Argos system for which the French Space Agency is prime contractor and is responsible for the development of system components both onboard and on the ground. Michel leads a team of nearly 10 people working together to ensure the integration of Argos instruments onboard the satellites of the partner organizations (NOAA, EUMETSAT, ISRO) as well as in-orbit validation of the system before handing the responsibility for day-to-day operations of the Argos system, including data distribution to users, to CLS.
