 Isotope analysis of bones excavated at archaeological investigations in the Norse settlements has found that fishing played an increasing economic role towards the end of the settlement's life.While the diet of the first settlers consisted of 80% agricultural products and 20% marine food, from the 14th century the Greenland Norsemen had 50–80% of their diet from the sea.In the Greenlandic Inuit tradition, there is a legend about Hvalsey.
