With one exception (the keynote address by Robert Picard), all of the essays in this volume are expanded versions of presentations made at the conference “Toward 2020: New Directions in Journalism Education,” held at Ryerson University in Toronto on 31 May 2014. Testifying to the urgent interest in professional renewal among journalism educators, more than one hundred people from Canada, the United States, Europe, and Australia attended the conference. The papers published here represent a reasonable cross-section of the issues discussed. The authors advance different ideas about where journalism education should go from here; at times they disagree with one another, but all share the underlying view that if business as usual was ever a viable option, this clearly is no longer the case.

Many inlets along the coastline of North America are deep, wide bays which are connected to the ocean by a short channel of much smaller cross-section. Figure 1 is a schematic sketch of such an inlet. It is usual in these inlets that the tide curve (water surface elevation vs. time) in the bay does not coincide with that in the ocean. The range of variation is discussed by Caldwell (1) in a review of inlets in the United States. In addition, Caldwell classifies this type of inlet as one with an inadequate entrance. This term describes well the engineering problem encountered in most of them. There are high velocities in the entrance channel, usually near periods of slack water, which are inconvenient to navigation. In some instances these velocities combined with local geography constitute a serious hazard to shipping.
