MSQ first incorporated CARIS products into their workflow in 2009 with HIPS and SIPS and BASE Editor and in 2012 are looking to utilize the new functionality of the Engineering Analysis module to assist them in the management of their ports and waterways throughout Queensland. This paper will look into how BASE Editor and the Engineering Analysis Module are being utilized in the Ports and Waterways environment, with a focussed case study on the application with MSQ. In-cluded in this will be a detailed comparison of techniques for volume computation (such as end area volumes, hyperbolic and TIN volumes), a summary of the results that can be achieved and the associated advantages/disadvantages with each method.","PeriodicalId":284729,"journal":{"name":"International Hydrographic Review","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125894979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"On cotidal maps","authors":"H. A. Marmer","doi":"10.2307/208766","DOIUrl":"https://doi.org/10.2307/208766","url":null,"abstract":"N maps delineating the features of the earth, the sea is generally pictured as a vast plain undistinguished by any marks of whatever kind. Even when contour lines or soundings are shown in ocean areas it is to the land that they refer-to the land beneath the sea. The surface of the sea, however, is not a monotonous plane stretching from horizon to horizon. For altogether apart from the swells and waves which are brought about in the surface layers of the water by the play of wind and weather, the sea sustains periodic changes in response to the mighty pulse of the tide-producing forces. Twice daily, in rhythmic fashion, the tide-producing forces of sun and moon stir the sea to its depths and give rise to the phenomena which for short are called the tide. In so far as our knowledge of the tide is based on observed data, it may be said to be confined wholly to the coast line. The difficulties involved in measuring the rise and fall of the tide in the open sea are obvious, and as yet there are no such observations at hand. To be sure the mid-ocean islands interrupt, here and there, the wide expanse of tidally unknown seas; but these islands are few in number. Moreover, the tide rising and falling on the island shores is no longer the unaffected open ocean tide; for in breaking the uniformity of the ocean depths, the islands by the same token modify the tide. It may perhaps not be out of place here to emphasize the fact that the tide has its birth in the open ocean basins. It is the action of the tide-producing forces of sun and moon on the waters of these huge basins that makes possible the rise and fall along the coast. What, geographically, is the course of the tide across the oceans? How can the progress of the tide from place to place be pictured? It is these questions that cotidal maps attempt to answer.","PeriodicalId":284729,"journal":{"name":"International Hydrographic Review","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127322338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The echo trace of the lake bottom was obtained from the ice surface. It is obviously easy to determine accurately the positions of soundings from that surface. Therefore, soundings were carried out more rapidly and accurately on the surface of the ice than they would have been from a boat. Furthermore, the detection of schools of fish from the ice surface was successful for the first time, and the transmission loss of ultrasonic waves in artificial ice and in natural ice was also measured.","PeriodicalId":284729,"journal":{"name":"International Hydrographic Review","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123229927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find, apart from the Himalayan regions, that T ranges from + 3,700 to — 6,700 feet. We accordingly are compelled to deny the existence of H a y f o r d isostasy in continental India. In the Himalayan regions, so far as they have been gravitationally explored, we find on the other hand that gravity anomalies are — on average, and to a less degree at individual stations — largely reduced by the H a y f o r d concept. My conclusions are (a) that departure from H a y f o r d ’ s concept by amounts of the order of 1 = 1,000 feet is the rule, not the exception, so far as India, excluding the Himalayas, is concerned; (b) that in widely extended regions of great topographical relief (several thousand feet in altitude) this same departure from H a y f o r d ’ s concept occurs (of order T — 1,000 feet), but in this case the larger residue of the topography is compensated, on average over considerable areas. This does not imply compensation exactly according to H a y f o r d ; but H a y f o r d ’ s concept gives a convenient basis for com­ putation, which may properly be used failing any better general concept, (c) I accept H a y f o r d as a standard from which anomalies may be reckoned. I would personally incline to make as standard the conception of compensation by a skin density (which would be infinite and have no physical reality) at some appropriate level. This skin density would be equivalent to a variety of real distributions which could be explored at leisure with a view to determining the most plausible, when associated with the ano­ malies. I am deterred from employing the skin density by the fact that the computation on the basis of H a y f o r d ’ s hypothesis has been made for a great number of gravity stations and is widely understood. It is desirable to make allowance for some form of compensation in mountain regions — at least in the case of the Himalayas and, I believe, in general; I also think the same need exists in the case of the oceans. In areas not much above sea-level there is little to compensate, and it is of little conse­ quence whether any allowance is made or not. It would, however, be difficult and arbi­ trary to draw a dividing line between mountainous and non-mountainous regions, and it is wholly unlikely that there is any precise division. Hence it is simplest to accept H a y f o r d ’ s concept as the standard for both mountainous and non-mountainous regions, i.e. invariably. I am accordingly using H a y f o r d ’ s concept for what it is worth.
