$\"\"$ <\/a>Malgrat la duresa de les condicions ambientals de l\u2019Ant\u00e0rtida, el continent m\u00e9s fred, distant i inaccessible del planeta constitueix un lloc idoni per a la recerca cient\u00edfica. Aix\u00ed ho mostrar\u00e0 el ge\u00f2graf Marc Oliva en una xerrada que pronunciar\u00e0 avui dimecres a les 19h a la Biblioteca de Tordera, en el marc del projecte divulgatiu Toc, toc<\/em> de la Universitat de Barcelona.<\/p>\n

L\u2019ambient inh\u00f2spit de l\u2019Ant\u00e0rtida ha fet que el continent es preservi de l\u2019acci\u00f3 humana directa durant la hist\u00f2ria de la nostra esp\u00e8cie. Encara avui \u00e9s un territori pr\u00e0cticament verge, tret de per un parell d\u2019excepcions: les bases permanents i estivals de diversos pa\u00efsos, les quals realitzen principalment tasques d\u2019investigaci\u00f3, i un turisme que es restringeix sobretot a la zona de la Pen\u00ednsula Ant\u00e0rtica, la regi\u00f3 m\u00e9s propera a Am\u00e8rica del Sud.<\/p>\n

El fet de mantenir-se gaireb\u00e9 intacte el fa un lloc excepcional per a estudis del camp de la climatologia, les geoci\u00e8ncies o la biologia d\u2019organismes i d\u2019ecosistemes, entre moltes altres disciplines. Per exemple, el gel del casquet que cobreix el continent roc\u00f3s, en alguns llocs al voltant dels dos kil\u00f2metres de gruix, amaga en el seu interior bombolles d\u2019aire de l\u2019atmosfera que hi havia a la Terra fa centenars de milers d\u2019anys, el qu\u00e8 permet estudiar l\u2019evoluci\u00f3 clim\u00e0tica de la zona i del m\u00f3n durant tot aquest per\u00edode.<\/p>\n

En Marc Oliva, doctor en geografia i actualment investigador a la Universitat de Lisboa, estudia els ecosistemes de zones polars i d\u2019alta muntanya. De moment ja ha visitat sis vegades l\u2019Ant\u00e0rtida (i dues l\u2019\u00c0rtic) per participar en campanyes de recerca centrades en l\u2019estudi i la reconstrucci\u00f3 d\u2019ambients i climes passats. En la seva xerrada donar\u00e0 a con\u00e8ixer el seu treball i explicar\u00e0 en primera persona qu\u00e8 representa fer recerca en un ambient tan g\u00e8lid i remot.<\/p>\n

La xerrada titulada \u201cL\u2019aventura de fer ci\u00e8ncia a l\u2019Ant\u00e0rtida\u201d ser\u00e0 avui a les 19:00h a la biblioteca de Tordera.<\/p>\n","protected":false},"excerpt":{"rendered":"
