Noon seminar - Microbial processes in Arctic sediments

Monday, February 18, 2019, 12:15AM - 1:15AM

Speaker

Jesse Colangelo

GEOL

Location:

SEEC room S228

Microbial processes in Arctic environments have received progressively more attention in recent decades, but this attention has disproportionately focused on community composition and activity from terrestrial permafrost.

This talk will focus on projects focusing on microbial ecology, physiology, and geochemistry from subterranean Arctic brines and hypersaline spring sediments, as well as biological contributions to isotopic biosignatures used to constrain past environmental conditions. The last part of the talk will focus on projects I hope to undertake in the near future, focusing on Arctic coastal sediment microbial communities and their responses to physical and chemical perturbations associated with climate change and inevitable anthropogenic development of Arctic regions.

Coffee hour

Coffee and cookies will be served starting at 11:45 a.m. outside S228.

Audience

Free and open to the public.
