Written by the director of the writing program at Dartmouth College and the authors of the leading introductory film-studies text, Writing About Movies is the only writing guide a student of film will need.

Not only will UNCLOS dictate for those nations the extent, volume and nature of the rights ratifying nations should include in their marine cadastres, but also the ways in which the outer limit of the marine cadastre is constructed. Land cadastres have traditionally represented property rights in two-dimensional parcel form, with the boundaries of each parcel coinciding with the ownership boundaries of each plot of land. In this way, cadastres have usually represented property rights in a bundled format, with many different types of rights existing within each unique parcel. Typically, one of these rights is the right to exclude others from the property. However, in a marine environment, individual ownership of a “parcel ” is not the norm. International law (e.g.: UNCLOS, or customary international law), public rights, and government ownership more frequent...

From the coastal upland to the limits of the Continental Shelf, there are myriad property boundaries and jurisdictional limits. Some, like the limits of fisheries zones, have long been portrayed on charts. However, most are defined only in law and legal documents, and few could be delimited today without any grounds for dispute. Yet the oceans are perhaps Canada's greatest natural resource. This paper will highlight the complexity of Canada's ocean spaces when they are viewed from the perspectives of state, private, and common property. Legal problems range from undefined aboriginal rights along the coast and conflicting public and private rights to jurisdictional uncertainty and the definition of the continental shelf. Technical issues include datums, databases, and "due publicity". Examples of these issues will be discussed in the context o...

Against this backdrop, the paper explores the concept of producing a new edition of GEBCO and concludes that there will not be a “sixth edition” with the same meaning that earlier editions had. Rather, sounding data from navigational hydrography, contours from the IOCs regional bathymetric maps, multibeam data from the deep ocean, and altimetry –derived bathymetric information will be contributed to a digital data base from which all marine science can draw seafloor morphologic information.

For example, rapid advances in multibeam technology and increasing interest in deeper areas of the ocean driven by UNCLOS mean that IHO SP 44, Standards for Hydrographic Surveys, 4th Edition, needs to be reviewed and expanded. SP44 provides 4 different requirements for vertical accuracy, successively degrading from the critical to navigation inshore region to the offshore deep regime. Requiring lower standards in deeper water has some justification for navigational charting, yet ignores the needs of a wide spectrum of other ocean users, and ignores the standard that MBES are capable of achieving. Article 76 of UNCLOS, for example, requires the accurate location of the 2500m contour, a location which the current version of SP44 allows hundreds of meters to kilometres of horizontal uncertainty. Furthermore, the ability of swath bathymetric sonars to achieve vertical accuracy actually increases with depth. For these reasons, it is...
