Descriptive material and sea level datum to mean low water conversionfigures have been derived from United States Coast and GeodeticSurvey tidal bench mark data and personal communications.SELECTEDREFERENCE1. Some construction activities require elevations based upon localtidal intervals. The relative accuracy of a tidal bench mark and, there<strong>for</strong>e,the accuracy of any level llne run from it, is directly related tothe period of observation used to establish the datum. For a discussionof the principles involved in the determination of tidal datum planesand the accuracy attainable, the following reference is indispensable:U.S. Department of Commerce, Tidal Datum Planes, Special PublicationNo. 135 (Washington: Government Printing Office, 1951),price $0.70.43NEW JERSEY GEOLOGICAL SURVEY
