GenHack2 est un challenge de donn\u00e9es organis\u00e9 et g\u00e9r\u00e9 par l’Ecole Polytechnique avec le soutien de BNP Paribas et Mercator Ocean International.   Ce hackathon vise \u00e0 rassembler les \u00e9tudiants les plus brillants des meilleures universit\u00e9s du monde pour travailler sur l’\u00e9volution de la temp\u00e9rature des oc\u00e9ans au fil des ans dans le contexte du changement climatique. <\/h6>

 Pourquoi est-il important d’\u00e9tudier la temp\u00e9rature des oc\u00e9ans ?<\/span> <\/span><\/h3>

La temp\u00e9rature moyenne de la surface des oc\u00e9ans a augment\u00e9 d’environ 0,6 degr\u00e9 Celsius depuis 1901, \u00e0 un rythme moyen de 0,08 degr\u00e9 Celsius par d\u00e9cennie.  Le r\u00e9chauffement continu des oc\u00e9ans entra\u00eenera une augmentation de la fr\u00e9quence des vagues de chaleur marine et une acc\u00e9l\u00e9ration de l’\u00e9l\u00e9vation du niveau de la mer, de la fonte des glaces et de l’acidification des oc\u00e9ans, ce qui aura un impact durable sur la biodiversit\u00e9 marine, ainsi que sur la vie et les moyens de subsistance des communaut\u00e9s c\u00f4ti\u00e8res et d’autres.<\/p>

Le d\u00e9fi<\/span> <\/span><\/h3>

Les donn\u00e9es mondiales relatives aux temp\u00e9ratures \u00e0 proximit\u00e9 de la surface proviennent de navires, de bou\u00e9es et de mesures satellitaires des oc\u00e9ans. Cependant, la mesure in situ de la temp\u00e9rature sur un maillage fin est souvent trop co\u00fbteuse. Il est donc essentiel de d\u00e9velopper un mod\u00e8le capable de fournir des cartes de temp\u00e9rature \u00e0 fine \u00e9chelle pour mieux \u00e9valuer les risques climatiques. <\/span><\/span><\/p>

Un pas de plus vers des solutions possibles<\/span><\/span><\/h3>

GenHack2 est un d\u00e9fi de donn\u00e9es de mod\u00e8les g\u00e9n\u00e9ratifs pour \u00e9tudier l’\u00e9volution de la temp\u00e9rature des oc\u00e9ans \u00e0 travers les ann\u00e9es dans le contexte du changement climatique, sur la base de donn\u00e9es r\u00e9elles fournies par Mercator Ocean. Il s’agit d’augmenter et d’enrichir le jeu de donn\u00e9es par de nouvelles donn\u00e9es. Plus pr\u00e9cis\u00e9ment, les \u00e9quipes tenteront de travailler sur l’\u00e9volution des donn\u00e9es de temp\u00e9rature des oc\u00e9ans (fournies par Copernicus Marine Service) en d\u00e9veloppant des cartes de temp\u00e9rature \u00e0 une \u00e9chelle plus fine. <\/span><\/p>

L’inscription, la constitution des \u00e9quipes et le lancement ont d\u00e9j\u00e0 eu lieu, tandis que l’\u00e9v\u00e9nement passe maintenant par 3 phases d’\u00e9valuation qui se termineront \u00e0 la mi-d\u00e9cembre.<\/p>

Environ 300 \u00e9tudiants de 53 universit\u00e9s, repr\u00e9sentant 27 nations diff\u00e9rentes, se sont inscrits. 56 \u00e9quipes de 3 \u00e0 5 \u00e9tudiants ont \u00e9t\u00e9 constitu\u00e9es pour ce hackathon. Karina von Schuckmann, Muriel Lux et Beno\u00eet Hartmann ont s\u00e9lectionn\u00e9 les donn\u00e9es Copernicus pour un exercice sur la temp\u00e9rature de surface de la mer (satellite SST ESA-CCI), tandis que Jean-Michel Lellouche, Elisabeth Remy, Marie Drevillon et Yann Drillet agissent en tant que mentors en r\u00e9pondant aux questions des \u00e9tudiants.<\/p>
