A new “Science on Tap” monthly pub series will feature informal 20-30 minute presentations geared toward the general public and delivered by local scientists based on their research or topics within their areas of expertise. It is organized by the Northern Michigan University chapter of Sigma Xi-The Scientific Research Society and hosted by the Ore Dock Brewing Company.

The series kicks off with “Marquette Rocks: Regional Geology of the Precambrian Era” at 7 p.m. Thursday, Jan. 15, at the Ore Dock. Dick Ziegler, an instructor in NMU’s earth, environmental and geographical sciences department, will give the talk. A question-and-answer session will follow. There is no charge to attend.

With the exception of January, series presentations typically will be held on the second Thursday of each month.
