Abstract:
The Canadian Hydrographic Service (CHS) expects the skillsets of its multidisciplinary hydrographers to evolve as the field of hydrography undergoes a digital transformation. To characterize these changes, the CHS organized a virtual workshop titled Hydrographer of the Future, in which it heard the perspectives of international colleagues in other Hydrographic offices (HO’s), industry, and academia. Despite some variations, common themes emerged: the changing technological context, people and culture, and the future role of hydrography. The results of this workshop support the CHS’ own internal planning; however, the CHS also hopes to continue learning from its international partners and share its experiences through the International Hydrographic Organization’s (IHO) e-learning center.

Abstract:
The year 2021 marks the 50th anniversary of the East Asia Hydrographic Commission (EAHC). It was established in 1971 as the third oldest Regional Hydrographic Commission located in East Asia. Since then, EAHC has progressed in cooperation of hydrographic services and in development of hydrographic technology for navigation safety and other aims. This article describing comprehensive historical steps and efforts of a Regional Hydrographic Commission in an important area of maritime transport will present readers a suggestive model of regional cooperation in hydrography. One of the suggestions can be summarized that the keys to development of Regional Hydrographic Commission are strong intention, initiative, unity and enthusiasm to leave no one behind.

Abstract:
Combining misaligned spatial data from different sources complicates spatial analysis and creation of maps. Conflation is a process that solves the misalignment problem through spatial adjustment or attribute transfer between similar features in two datasets. Even though a combination of digital elevation model (DEM) and vector hydrographic lines is a common practice in spatial analysis and mapping, no method for automated conflation between these spatial data types has been developed so far. The problem of DEM and hydrography misalignment arises not only in map compilation, but also during the production of generalized datasets. There is a lack of automated solutions which can ensure that the drainage network represented in the surface of generalized DEM is spatially adjusted with independently generalized vector hydrography. We propose a new method that performs the conflation of DEM with linear hydrographic data and is embeddable into DEM generalization process. Given a set of reference hydrographic lines, our method automatically recognizes the most similar paths on DEM surface called counterpart streams. The elevation data extracted from DEM is then rubbersheeted locally using the links between counterpart streams and reference lines, and the conflated DEM is reconstructed from the rubbersheeted elevation data. The algorithm developed for extraction of counterpart streams ensures that the resulting set of lines comprises the network similar to the network of ordered reference lines. We also show how our approach can be seamlessly integrated into a TIN-based structural DEM generalization process with spatial adjustment to pre-generalized hydrographic lines as additional requirement. The combination of the GEBCO_2019 DEM and the Natural Earth 10M vector dataset is used to illustrate the effectiveness of DEM conflation both in map compilation and map generalization workflows. Resulting maps are geographically correct and are aesthetically more pleasing in comparison to a straightforward combination of misaligned DEM and hydrographic lines without conflation.

Abstract:
After Global Navigation Satellite Systems (GNSS) were first used in the field of hydrography in 1980, developments in hydrographic surveying accelerated. Survey precision in hydrography has been improved for both horizontal and vertical positioning and seafloor acoustic measurement by means of these new developments. Differential Global Positioning System (DGPS), Real Time Kinematic (RTK) and Network RTK (NRTK) techniques are the satellite-based positioning techniques that are commonly used in shallow water surveys and shoreline measurements. In line with these developments, the newer Precise Point Positioning (PPP) has been introduced. Combining precise satellite positions and clocks with dual-frequency GNSS data, PPP can provide position solutions from the centimetre to decimetre level. In this study, the coordinates of control points were determined by using the Post-Process PPP (PP-PPP) technique. Seven test points, which are the points of the Continuously Operating Reference Station - Turkey (CORS-TR) network, are selected near the shorelines within Turkey. The 24-hour data was split from one to six hours by one hour periods. Automatic Point Positioning Service (APPS) was selected to process the data. The poisoning error of the test points were given and compared with International Hydrographic Organization (IHO) S44 hydrographic survey standards.

Abstract:
The Differential Global Positioning System (DGPS) is a marine navigation system operating at frequencies of 283.5–325 kHz, which is now the primary method for locating vessels in coastal shipping, as well as hydrography and mapping systems worldwide. Its positioning accuracy is determined by the following: the pseudorange error to Global Positioning System (GPS) satellites, the age of pseudorange corrections, and the value of the Horizontal Dilution Of Precision (HDOP), which, in terms of accuracy, is crucial in positioning using GPS satellites. In 2020, the International Hydrographic Organization (IHO) introduced a new (the highest) order of hydrographic surveys, i.e., the Exclusive Order, which requires a positioning system to provide an accuracy of 1 m (p = 0.95). The aim of this article is to provide an answer to the question as to whether the maritime DGPS system, whose positioning accuracy is constantly increasing with that of the GPS system, fulfils the requirements for the hydrographic surveys of harbours. To this end, an extensive experimental study on the maritime DGPS system, involving a total of nearly 3.5 million fixes, was conducted. Statistical analyses showed that when ensuring the HDOP values range from 0.8 to 1.4, the DGPS system can be used in hydrographic surveys of harbours.

Egg mortality: predation and hydrography in the central Baltic. – ICES Journal of Marine Science, 68: 1379–1390. Cod and sprat are the dominant fish species in the Baltic pelagic ecosystem, both of great economic importance and ecologically strongly interlinked. Management of both species is challenged by highly variable recruitment success. Recent studies have identified predation and hydrographic conditions during the egg phase to be of critical importance. Two years of extensive field investigations in the Bornholm Basin, central Baltic Sea, were undertaken. In 2002, a typical stagnation situation characterized by low salinity and poor oxygen conditions was investigated, and in early 2003, a major inflow of North Sea water completely changed the hydrographic conditions by increasing salinity and oxygen content, thereby altering ecological conditions. The goal was to quantify egg mortality caused by predation and hydrography, and to compare these estimates with independent estimates based on cohort analysis. Results indicated high intra-annual variability in egg mortality. Cod and sprat egg mortality responded differently to the major Baltic inflow: mortality related to hydrographic conditions increased for sprat and decreased for cod. On the other hand, predation mortality during peak spawning decreased for sprat and increased for cod.

Abstract:
Accurate maps of regional surface water features are integral for advancing ecologic, atmospheric and land development studies. The only comprehensive surface water feature map of Alaska is the National Hydrography Dataset (NHD). NHD features are often digitized representations of historic topographic map blue lines and may be outdated. Here we test deep learning methods to automatically extract surface water features from airborne interferometric synthetic aperture radar (IfSAR) data to update and validate Alaska hydrographic databases. U-net artificial neural networks (ANN) and high-performance computing (HPC) are used for supervised hydrographic feature extraction within a study area comprised of 50 contiguous watersheds in Alaska. Surface water features derived from elevation through automated flow-routing and manual editing are used as training data. Model extensibility is tested with a series of 16 U-net models trained with increasing percentages of the study area, from about 3 to 35 percent. Hydrography is predicted by each of the models for all watersheds not used in training. Input raster layers are derived from digital terrain models, digital surface models, and intensity images from the IfSAR data. Results indicate about 15 percent of the study area is required to optimally train the ANN to extract hydrography when F1-scores for tested watersheds average between 66 and 68. Little benefit is gained by training beyond 15 percent of the study area. Fully connected hydrographic networks are generated for the U-net predictions using a novel approach that constrains a D-8 flow-routing approach to follow U-net predictions. This work demonstrates the ability of deep learning to derive surface water feature maps from complex terrain over a broad area.

Abstract:
The relationship between the general circulation of the ocean and, along-isopycnal and vertical mixing is explored. Firstly, advection down isopycnal tracer gradients is related to mixing in specific regions of the ocean. Secondly, a general inverse method is developed for estimating both mixing and the general circulation. Two examples of down gradient advection are explored. Firstly the region of Mediterranean outflow in the North Atlantic. Given a known transport of warm salty water out of the Mediterranean Sea and the mean hydrography of the eastern North Atlantic, the vertical structure of the along-isopycnal mixing coefficient, K, and the vertical mixing coefficient, D, is revealed. Secondly, the Southern Ocean Meridional Overturning Circulation, SMOC, is investigated. There, relatively warm salty water is advected southward, along-isopycnals, toward fresher cooler surface waters. The strength and structure of the SMOC is related to K and D by considering advection down along-isopycnal gradients of temperature and potential vorticity. The ratio of K to D and their magnitudes are identified. A general tool is developed for estimating the ocean circulation and mixing; the \textit{tracer-contour inverse method}. Integrating along contours of constant tracer on isopycnals, differences in a geostrophic streamfunction are related to advection and hence to mixing. This streamfunction is related in the vertical, via an analogous form of the depth integrated thermal wind equation. The tracer-contour inverse method combines aspects of the box, beta spiral and Bernoulli methods. The tracer-contour inverse method is validated against the output of a layered model and against in-situ observations from the eastern North Atlantic. The method accurately reproduces the observed mixing rates and reveals their vertical structure.

Abstract:
Details of research into the automated generation of a digital database of hydrographic charts is presented. Low level processing of digital images of hydrographic charts provides image line feature segments which serve as input to a semi-automated feature extraction system, (SAFE). This system is able to perform a great deal of the building of chart features from the image segments simply on the basis of proximity of the segments. The system solicits user interaction when ambiguities arise. IThe creation of an intelligent knowledge based system (IKBS) implemented in the form of a backward chained production rule based system, which cooperates with the SAFE system, is described. The 1KBS attempts to resolve ambiguities using domain knowledge coded in the form of production rules. The two systems communicate by the passing of goals from SAFE to the IKBS and the return of a certainty factor by the IKBS for each goal submitted. The SAFE system can make additional feature building decisions on the basis of collected sets of certainty factors, thus reducing the need for user interaction. This thesis establishes that the cooperating IKBS approach to image interpretation offers an effective route to automated image understanding.

Abstract:
Airborne lidar bathymetry (ALB) is a method used to survey and map coastal and littoral zones. Along with extracting seafloor depth and reflectance in the surveyed area, a fundamental requirement of these surveys is to detect underwater targets, hazards, or obstructions. The ability to detect underwater targets depends on a target's dimensions and reflectance, the depth and turbidity of the water, system and survey configuration, data processing capabilities, and algorithmic sophistication. Understanding the effects of each of these factors on the performance of underwater target detection is essential in determining the target detection capabilities of a proposed ALB system. After detailing the development of a simulation environment to model received ALB system waveforms, this work explores the theoretical target detection capabilities of an ALB system.

Abstract:
The period from 1808 to 1829, largely neglected by those historians who have looked at the Hydrographic Office, was the crucial formative period for expansion that laid the solid foundations which later Hydrographers could then exploit. The context, achievements and failures of the Admiralty’s hydrographic function, including surveying, chart production, supply, sales and its contribution to the Navy and the scientific world, as an all encompassing beast has been overlooked; the Admiralty placed the responsibility for those tasks on the shoulders of its Hydrographer. Subsequently he determined the success or failure of the office, using his initiative to expand and develop opportunities benefiting the Admiralty, as well as managing a valuable resource of geographical intelligence, fostering links with scientists and the international hydrographic community. The Hydrographer also found himself creating his own policies, serving as Secretary to the Board of Longitude, being a consultant on navigational matters, taking responsibility for the acquisition, supply and maintenance of chronometers for the Navy, as well as being a focal point for issues concerning pay, promotion and manning for surveying specialists. The period from 1808 to 1829 saw many changes, which gave rise to numerous opportunities for expansion. The Admiralty Board and William, Duke of Clarence (as the last Lord High Admiral), both had a direct influence in the way the office expanded, which saw innovation and experimental work become part of the Hydrographer’s routine, especially after the Peace of 1815. But expansion required funding and at a time when internal economy appeared to the be the main objective within the Admiralty, Captain Thomas Hurd managed not only to establish a 100% increase in surveying capacity but laid the foundation for a distinct specialist and professional core of survey officers. His successor, Captain William Parry, despite his absences, overhauled working practices in the office, set standards for surveyors to follow and continued to expand the number of survey ships in commission. Subsequently Captain Francis Beaufort was left the most highly efficient hydrographic office since its foundation in 1795.

There is a vital need to update the hydrographic database of the United States. NOAA statistics show that with current survey technologies it will take nearly 40 years to update U.S. nautical charts. Hydrographic surveys require a careful record of depth, position, tide, and the motions of the survey platform. The U.S. Army Corps of Engineers is one highly regarded organization which performs hydrographic surveys. They impose a strict standard of accuracy for certain surveys. For these Class 1 surveys, position must be within 6 meters and depth must be measured within 0.5 feet. This thesis documents the development of a new technology to meet these needs and provide hydrographic surveys in more cost effective ways than existing techniques. Since 1993 Autonomous Surface Craft (ASC) have been under development at the MIT Sea Grant College Program. Hydrographic surveying was the first practical mission approached by an ASC. The ASC ARTEMIS used simple navigation and control systems and a basic recreational depth sounder to demonstrate the possiblity of performing surveys with ASC. This background led to the developments presented here. This project had two goals, the first was to develop an ASC which was better suited for hydrographic surveys than ARTEMIS. This required designing and constructing a new ASC with improved endurance, speed, payload, and stability. This goal was met with the development of the ASC ACES (Autonomous Coastal Exploration System). The development of ACES and its preliminary field tests, which provided a hydrographic survey which was 78% Class 1, are documented in this work. The second goal of this effort was to configure the new ASC for high fidelity hydrographic surveys. This required selection of new sensors to measure position, depth, tide, and the motions of the ASC. Conventional systems were evaluated and a final design was selected which incorporated the latest developments in the application of the Global Positioning System (GPS). By using GPS sensors to account for all variables except depth, ACES is able to meet the high standards of a Class 1 survey. Using an Acoutisc Doppler Current Profiler to measure depth provides ACES with a high quality and versatile sensor to employ in such surveys. This project has demonstrated the potential for ASC to be used in the field of hydrographic surveys. ACES, A system capable of providing high fidelity hydrographic surveys to meet the needs of the U.S. survey community has been designed and built. This system has matched the USACE surveys with 78% accuracy in a prototype configuration. The final high fidelity survey configuration of ACES will provide Class 1 or better surveys more cost effectively than manned survey vessels.

Denmark Strait Overflow Water (DSOW) constitutes the densest portion of North Atlantic Deep Water, which feeds the lower limb of the Atlantic Meridional Overturning Circulation (AMOC). As such, it is critical to understand how DSOW is transferred from the upstream basins in the Nordic Seas, across the Greenland-Scotland Ridge, and to the North Atlantic Ocean. The goal of this study is to characterize the hydrographic structure of the different DSOW constituents at the sill before the water descends into the Irminger Sea using temperature and salinity (T/S) data from 111 shipboard crossings in the vicinity of the sill, collected between 1990 and 2012. The individual realizations indicate that weakly stratified "boluses" of DSOW frequent the sill and contribute the densest water to the overflow. This study also characterizes the structure, size, and location of the boluses and relates them to the T/S modes found at the sill. Lastly, historical hydrographic data from the Nordic Seas are used to make inferences regarding the origin of the boluses.

Abstract:
The United States Army Corp of Engineers relies on accurate and detailed surface models for various construction projects and preventative measures. To aid in these efforts, it is necessary to work for advancements in surface model creation. Current methods for model creation include Delaunay triangulation, raster grid interpolation, and Hydraulic Spline grid generation. While these methods produce adequate surface models, attempts for improved methods can still be made. A method for raster based spline creation is presented as a variation of the Hydraulic Spline algorithm. By implementing Hydraulic Splines in raster data instead of vector data, the model creation process is streamlined. This method is shown to be more efficient and less computationally expensive than previous methods of surface model creation due to the inherent advantages of raster data over vector data.

Abstract:
The main field of application of a multi-beam echosounder is hydrographic surveying, in other words acquisition of bottom topography information. This kind of bathymetric data is needed by a large number of users for harbour and coastal zone management, resource exploration, hydrographic charting for safety of navigation and many other tasks. Tools for highly efficient investigation of the seafloor, including rapid sediment classification, as well as reliable object detection are of high interest to offshore construction projects. Throughout the last couple of years, ATLAS Hydrographic has been concentrating on the development of the next generation of hydrographic survey echosounders. One of the results is the ATLAS FANSWEEP 30 family of multi-beam echosounders (MBES). This family of sonars offers an innovative new approach of multi-beam echosounder technology for hydrographic surveys. The ATLAS FANSWEEP 30 COASTAL, the first member of the ATLAS FANSWEEP 30 MBES family, is breaking new ground. Innovations, such as Simultaneous Multi-Ping, wide bandwidth transducer, multiple time and multi-view scanning of the seafloor for object search, address a single purpose: to improve survey efficiency while multiplying data reliability and resolution. With the FS30C the new Simultaneous Multi-Ping (SMP) is introduced. SMP utilises the complete frequency range between 100 kHz and 200 kHz to transmit and receive eight frequency separate pings at every ping interval. Four of these eight pings are forward, the other four backward looking mapping the seafloor from two independent directions. Thus, every bit of the mapped seafloor is looked at from two different directions. The 8x Simultaneous Multi-Ping enables the hydrographer to run the survey operation at high speeds. Still, the 8x SMP can ensure more than 300% bottom ensonification. That means every patch of seafloor is measured at least 3-times at one pass. The gained data redundancy is used to enhance not only data accuracy and reliability, but in particular the capability to recognise objects on the sea floor. Beginning at signal transmission, through reception beamforming to the point of real-time data gridding capabilities, the complete data flow is controlled by a built-in data evaluation solution. The new ATLAS FANSWEEP 30 COASTAL is a well suited tool to satisfy actual and upcoming demands in highly efficient and most reliable survey operations.

Abstract:
In contrast to the hydrological and hydrochemical zoning, hydrographic and water management zoning of Ukraine (2016) was created on a basin basis, taking into account the boundaries of river basins, and not physiographic zoning. The main function of hydrographic and water management zoning is water management. Primary is hydrographic zoning, and water management - based on it. The description of modern hydrographic zoning of the territory of Ukraine, approved in 2016 by the Verkhovna Rada of Ukraine and included in the Water Code of Ukraine is given. Hydrographic zoning is carried out for the development and implementation of river basin management plans. On the territory of Ukraine nine areas of river basins are allocated: Dnipro; Dnister; Danube; Southern Bug; Don; Vistula; rivers of the Crimea; rivers of the Black Sea coast; rivers of the Azov Sea coast 13 sub-basins are allocated in four river basins district. The water management zoning is described - the division of hydrographic units into water management areas, which is carried out for the development of water management balances. In the regions of the river basins in the territory of Ukraine allocated 132 water management areas, 59 of which are located in the Dnipro basin. About 9,000 bodies of surface water allocated for monitoring in Ukraine. Approved zoning is the implementation of the provisions of the EU Water Framework Directive 2000/60 / EC in the management of water resources in Ukraine. Modern hydrographic and water management zoning of the territory of Ukraine approximates the management of water resources of the state to European requirements.
