COASTAL 



TIDINGS 



Corrosion in Coastal Buildings 



a e of the best ways to hold 

 buildings together during severe storms is 

 to install sheet- 

 metal hurricane 

 clips where the 

 roof and walls 

 meet. But when 

 the Federal 

 Emergency 

 Management 

 Agency 

 (FEMA) 

 realized how 

 severely these 

 connectors 

 corrode when 

 exposed to salt 

 air, it sought 

 help from 

 Spencer Rogers, 

 North Carolina 

 Sea Grant's 

 coastal erosion 

 and construction 

 specialist. 



Rogers 

 identified the 

 serious consequences of corrosion for 

 buildings near the ocean using historical 



A hurricane strap connecting two beams. 



records from LaQue Corrosion Services, a 

 North Carolina firm specializing in 

 corrosion 

 testing for 

 industry and 

 the military. 

 North Carolina 

 Sea Grant has 

 since funded 

 more than 10 

 years of full- 

 scale exposure 

 testing. 



Based on 

 this work, 

 Rogers wrote 

 a FEMA 

 technical 

 bulletin, 

 Corrosion 

 Protection for 

 Sheet-Metal 

 Connectors, 

 which is 

 distributed 

 nationally 

 to coastal 

 communities, builders and designers.

Students Lauded for Food 

 Technology Papers 



Two North Carolina State 

 University graduate students received 

 first and second places in a student 

 paper competition at the Annual 

 Institute of Food Technologists 

 Conference. North Carolina Sea Grant 

 supported both students' graduate 

 studies. 



Carol Dombroski developed a 

 novel approach to verify the safety of 

 strategies used to eliminate Vibrio 

 vulnificus bacteria from raw shellfish. 

 These strategies, which apply low heat 

 or freezing to reduce bacteria levels, are 



currently used to market raw in-shell 

 oysters. Vibrio vulnificus causes blood 

 poisoning that can spread quickly and 

 prove fatal to people with compromised 

 immune systems. 



Dombroski worked with Lee- Ann 

 Jaykus in the Department of Food 

 Science. 



Dina Requena focused on automat- 

 ing quality-assurance methods in the 

 production of fresh Atlantic blue crab 

 meat. She studied with S. Andrew Hale 

 in the Department of Biological and 

 Agricultural Engineering. □ — J.N.
