The last few years have seen a remarkable growth of interest in oceanography. The formation and endowment of the Woods Hole Oceanographic Institution, the reorganization of the Bermuda Station, and the activities of the Scripps Institution may be cited as a few of the achievements in which the American institutions have played an active part. The publications of a number of marine laboratories here and abroad show that they are investigating several problems which are of fundamental interest to the geologist as well as to the biologist. Of special mention are studies in marine sedimentation and, to a certain extent, submarine configuration.
