Thor Sigfusson in Business and Management Research,  marine technology entrepreneurs in Iceland are examined.  The article discusses how the entrepreneurs build their business network relationships and the effects of the formation of the Iceland Ocean Cluster on their relationships. This study finds that a formation of an industry cluster of marine technology entrepreneurs enhances the weak ties of the entrepreneurs and their skills in developing these weak relationships.
