inctAmbTropic II – Honorary Lecturer

O inctAmbtropic II co-patrocina juntamente com o programa CAPES-IODP (Projeto Geohazards) a vinda ao Brasil do prof. André Droxler, que durante o meses de Janeiro e Fevereiro de 2018 estará ministrado palestras e mini-cursos nas Universidades Federais do Rio Grande do Norte, Pernambuco e Bahia. A vinda do prof. Droxler foi uma iniciativa da profa. Helenice Vital (UFRN) membro do comitê gestor do inctAmbTropic II.

A programação resumida está apresentada abaixo juntamente com o resumé do prof. Droxler.

Professor André W. Droxler (Ph.D.)

Rice University – D of Earth, Environmental and Planetary Sciences – Houston, TX (USA)

"I am a professor in the Department of Earth Science and currently the Track Director of the Science Master’s Program – Subsurface Geoscience. My research has focused on studying the morphology of and the sediments accumulating on slopes and basin floors surrounding coral reefs and carbonate platforms. Over the past 30 years, I have conducted research programs mostly in the Bahamas, offshore Jamaica, along the Belize margin, in the western Gulf of Mexico, in the Maldives (Indian Ocean), along the Australian Great Barrier Reef and in the Gulf of Papua (Papua New Guinea). The main focuses of my research include the regional and global evolution of coral reefs through time, the paleo-oceanographic/climatic and sea level records archived in the sediments deposited around reefs and carbonate platforms. In contrast with my 30 years plus research a s a marine geologist, I am currently conducting research on Upper Cambrian Microbial Reefs in Mason County, Central Texas funded by an Industry Consortium in collaboration with my colleague Prof. Dan Lehrmann at Trinity University in San Antonio (Texas). My work has been funded by the National Science Foundation, the American Chemical Society, and grants from oil and gas companies. Before becoming an assistant professor at Rice in January 1987, I was a postdoctoral research scientist at the University of South Carolina from 1985 to 1986. I received my Master’s degree equivalent from the University of Neuchâtel (Switzerland) in 1978 and earned his Ph.D. from the Rosenstiel School of Marine and Atmospheric Sciences at the University of Miami (Florida) in 1984."

Entre 1992 e 2011 Groenlândia e Antártica já perderam 4 trilhões de toneladas de gelo

A subida do nivel do mar é uma das maiores ameaças às zonas costeiras do mundo. No Brasil uma das áreas que serão afetadas é a região norte-nordeste (veja esta postagem). Um estudo publicado na Science de autoria de Shepherd e colaboradores combinando medidas de  altimetria, interferometria gravimetria feita por satélites, determinou que entre 1992 e 2011 cerca de 4 trilhões de toneladas de gelo já derreteram na Groenlândia e Antártica, o que teria causado uma subida do nível do mar da ordem de 11mm.

Mudanças cumulativas na massa de gelo (eixo esquerdo) e nível do mar global equivalente (eixo direito) assumindo que 360Gt de gelo correspondem a 1mm de subida no nível do mar (Shepherd et al 2012)

O jornal The Guardian disponibilizou  ontem um clip de um documentário de  com a participação do  fotógrafo James Balog intitulado “Chasing Ice“,  premiado no Sundance Film Festival de 2012. O clip mostra a liberação de 7.4 km cúbicos de gelo da geleira Ilulissat na Groenlândia.

James Balog cerca de 03 anos atrás apresentou uma palestra muito interessante no TED talks sobre o seu trabalho no projeto Extreme Ice Survey documentando o recuo e a  diminuição do gelo no Alasca, Groenlândia e Islândia (veja abaixo):
