‘This groundbreaking monograph brings detail and great clarity to a topic whose treatment has frequently been piecemeal and even romantic. It makes a major contribution to our understanding of the early medieval settlement of the North Atlantic.’- Jonathan Wooding (Parergon vol 32:02:2015) "[This} book represents an example of scientific integrity at its finest…Into the Ocean is a valuable book, both for the specialist focused on the environmental and human history of the North Atlantic, and the general reader interested in the philosophy of science."- Russell Fielding, University of the South, Sewanee (The AAG Review of Books vol. 6 no. 4)
