Sea-level rise will be the topic of this month’s Mathews Maritime Foundation’s speaker’s meeting. Carl Hobbs, Emeritus Professor of Marine Science, will be the guest speaker at the meeting, which is scheduled for next Thursday, Nov. 20, beginning at 7 p.m. at the foundation’s museum on Main Street.

Having retired at the end of 2012 after more than 40 years of service at the Virginia Institute of Marine Science, Gloucester Point, Hobbs is the author or co-author of over 50 peer-reviewed publications including “The Beach Book,” published in 2012.

The meeting is open to the public ...
