The very first general us of the radars was when they were applied for detecting the aircrafts and surface ships in the course of the Second World War. At that time and for the intended use of the radar, the weather used to be treated as a real nuisance since it produced serious echo patterns making detection of the ships and aircrafts much more difficult and sometimes even impossible at all.

People did every effort to minimize subject weather echoes and came to the opinion that the weather information that can be obtained from the radars would be a very important and valuable supplement to the conventional techniques of weather observing that were available. Having the information received from both resources, they could perform a proper analysis and define the echoes.

The present publication provides information about the fundamentals of radars, including propagation and detection matters, radar measurements and reports, radar echo intensities etc. You will wind the instructions on proper reporting of the typical weather situations. The list of tables is provided as a supplemental information covering the characteristics of radars, intensity levels, and other info expected to be practically useful.

One of the best volumes available today on coastal hydraulics. This is the second, significantly updated and revised, edition of the book. The content of the publication opens with the basic information on the subject including motion equations applicable to the ideal fluids, sediment transport and viscous flow. This chapter is followed by the one on tides and currents - here the readers will get the information about the equilibrium tide, tidal streams and bores, numerical analysis methods etc.

The next chapter deals with the waves and covers the linear theory, diffraction and reflection of waves, longshore currents and their generation, ship waves, wind waves and other important aspects. The chapter devoted to the coastal sediment transport will tell readers about the suspended and bed load, littoral drift and roughness length, longshore drift, beach nourishment etc.

The rest of the chapters of the volume address such areas as coast and bed morphology, coastal protection and its planning, waves and structures including wave characteristics and associated forces, application of the spectral analysis method to wave loadings, and data acquisition through current and wave measurements, measurement of the sediment movement and littoral drift, and hydrographic surveys.

The main declared objective of the present volume was to introduce the engineering and mathematical approximation schemes to the readers and describe both kinetics and thermodynamics of the electro-chemical systems considered the fundamentals of the corrosion science. The material in each of the chapters has been given in a very easy-to-follow manner.

The readers will be provided with the clear explanations and definitions of all theoretical concepts involved. Every effort was made by the author to keep the mathematics as simple as possible to make sure that the students do not experience too much of difficulty when trying to understand the basics of the electrochemical processes relating to the corrosion. The readers are offered an opportunity to learn and understand the corrosion using the theory clearly explained with the aid of numerous images and figures, schemes and graphs.

Several example problems have been included in the book to better illustrate the application of the math and electrochemical concepts to solve the corrosion problems. The corrosion is one of the most serious problems to be paid attention in shipbuilding and exploitation and we would therefore recommend this book to every person involved in construction, handling and repair of ships.

An excellent collection of the safety posters developed in the frame of the Loss Prevention Program. This set is made of nearly sixty different posters. All of them are very informative and may be used on board ships to inform crew members and all visitors about the proper cargo handling techniques, signage, collision prevention etc. The posters are of high quality therefore they may be printed out at any size.

The ColRegs-related posters are the following - Responsibility, Safe Speed, Look Out, Risk of Collision, Heading on Situation, Overtaking, Crossing Situation, Action to Avoid Collision, Traffic Separation Scheme. Active by Give Way Vessel and Active by Stand On Vessel, and finally the one describing Restricted Visibility. The "If Only" posters cover the entry into enclosed spaces, pilot boarding arrangements and lifeboat launching systems, safe ship access and working aloft, persons in distress and manual handling of heavy cargoes, hot works and collisions, mooring operations, oily water separators, and heavy weather.

The "Safe Work" posters cover lifting operations and bridge management, safety management, working aloft and in the enclosed spaces, fall preventing devices and protective equipment, ship handling, planned maintenance etc. This is not a full list of posters - have a look and check the content, there are so many papers that may be of practical use both on board and ashore.

The Liverpool port of England has been treated as home town for maybe the oldest British Black community. The members of subject community date back the history of their entity at the XIX century, linking its establishing to the global wanderings and to the settlement of the African seafarers. The author of this interesting volume has given her readers a good and thorough analysis of how this story supports the local identity and politic, and this topic has become a window onto the race, nation and place politics in Britain.

The content of this publication by Jacqueline Nassy also provides examination of the rise of Black identity capturing the existing contradictions of Black diasporas in post-colonial Liverpool. According to the reviews submitted by readers, the book is one of the most sophisticated and nuanced volumes on this topic available today; in addition, it is ethnographically rigorous.

The volume has stretched the analysis mentioned above well beyond by political and somatic theoretical and reference debates. It shall definitely be considered a very important and, what is important, original and valuable contribution to the understanding the subjectivity of the Diaspora in this particular location...

Here is the collection of twelve hi-resolution safety posters released by the KVH Media Group. These images are intended to attract the attention of the crew members and visitors of the vessel to the main aspects of shipboard safety. The first poster is addressing the three points of contact approach, while the others are dealing with the tiredness and fatigue, affecting safety and health, handling deck plates, hot work, intervention, the monkey fist, out on deck, mooring deck safety, snap back zones, shipboard watertight doors, confines spaces, and hearing protection.

Though this collection of safety posters does not pretend to cover all areas of safety, it will still be useful and can be used on board any ship. The main and most important safety aspects have been covered and each of them is provided with some commentary explaining the importance of following safety procedures in each particular case, contributing to the overall safety of the vessel and people on board. We recommend all of you to have a close look in this set of images and feel free to use these posters as a part of the safety system of your vessel or for training purposes. An excellent and very practical resource.

Her childhood was marked by pretty unusual rhythm. Every year freezing and subsequent thawing of the water of Great Lakes served as a sort of signal making the beginning and the end of anther shipping season, which in turn meant months of waiting for her father, the Captain.

The text of this fascinating book features vivid details and really lovely storytelling - this is the way how the author is capturing so interesting and fascinating life of many shipping families - days and weeks of their lives used to revolve mainly around the shipping industry of that region.

The author has managed to paint a truly affectionate and intriguing portrait of her father who started as a pianist but then started to work on board an ore freighter and this was a beginning of his life on the water. He made an impressive career from deckhand and up to the Captain of the vessel - he worked as a Captain on as many as thirteen different vessels over twenty-years of his working at sea.

Ann, the author of this story, used to accompany her father to the ports of Toledo, Milwaukee, Cleveland and others, and she has used her memories to describe sailing and visiting the machinery room of the ship, stormy weather, starry nights, wheeling the ship together with the Captain. She is revealing insights into the real rewards and trials of being a wife of the Captain...

This publication has been worked out mostly by the invited speakers and lecturers of the Copenhagen workshop. The content of this volume is mainly focusing on the topics covered in the course of that workshop, summarizing the presentations, discussions that took place at that time, conclusions and also providing valuable technical recommendations.

In fact, this volume is one of the first successful attempts to provide interested readers with a general look on the integrated modeling approach. The publication is expected to be useful to the people with the serious interest in the modeling of the air pollution and meteorology; however, it will also present some practical interest to the persons involved in the meteorology science in any way, for example the students, practicing professionals, scientists and researchers.

The whole content of this document consists of the introduction depicting the methodology of integration, overview of the models and feedback mechanisms, and four big parts. The first part addresses the on-line modeling and feedbacks, while the second part deals with the off-line modeling and interfaces. The third part of the volume is dedicated to the validation and also several real-life case studies. Finally, the fourth and last art of the work is covering the strategy for the ACT-NWP integrated modeling.
