Writing About Movies offers students two books in one: a handy guide to the process of academic writing and a brief but thorough introduction to the basics of film form, film theory, and film analysis. 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.

The continuing explosion in communications technologies has impacted the way that formal education can be delivered to students seeking it. One element is the decreasing requirement for students to physically attend classes, exemplified perhaps by university courses ...

The United Nations Convention on the Law of the Sea should influence the marine cadastres of ratifying nations in several ways. 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...

Hydrography has an important role to play in coastal and offshore management of property rights, or marine administration. 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...

This paper attempts to position the GEBCO organization in time, that is, in the flow of events impacting the partnering organizations and the changes in technology that will influence GEBCO in the next few years. 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.

Keeping any standard up to date is a never-ending task. 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...

multiple dimensionality Three dimensions in space, one in time dynamism of marine data the inherent fuzziness of marine boundaries On land, usually hard boundaries (edge of property, side of a house) but most marine boundaries are very soft the need for spatial data structures that vary their relative positions and values over time must be able to simulate fluid or object motion, and be able to fix the motion at any moment in time. Marine data is often collected in profile form (horizontal and vertical) while land data are usually in area form Land data usually has total coverage, marine data usually has gaps. Deep bathymetry always has gaps.

Executive Summary Most ocean science relies largely on a geospatial infrastructure that is built primarily from bathymetry data collected underway from ships, archived, and converted into maps and digital grids. Bathymetry, the shape and composition of the seafloor, besides having vital importance to geology and navigation, is a fundamental element of studies of ocean modeling, deep water circulation, tides, tsunami forecasting, upwelling, fishing resources, wave action, sediment transport, environmental baselines, slope stability and risk, paleoceanography, site selection for platforms cables and pipelines, waste disposal, mineral extraction and sampling for environmental research. Recent developments in multibeam sonar mapping have so dramatically increased the resolution with which the seafloor can be portrayed, understood, used by other sciences and interacted with, that previous maps must be considered obsolete and scientific conclusions based on them re-examined and refined. T...

A successful Capacity Building project in hydrography is underway at the University of New Hampshire. Organised by the General Bathymetric Chart of the Oceans and sponsored by the Nippon Foundation, the programme trains hydrographers and other marine scientists in bathymetric mapping. Participants are formally prepared to produce bathymetric maps when they return to their home countries through a combination of graduate level courses and workshops, practical field training, participation in deep ocean research cruises, working visits to other laboratories and institutions, focused lectures from visiting experts, and the preparation of a bathymetry map of their area from public domain data. Intangible but necessary preparation includes the networking with professionals in bathymetry and related fields within Ocean Mapping, and the building of a cadre of graduates who will form the basis of international bathymetric mapping in the future.
