Due to its geographic position, geomorphology and certain signs of frequent occurrencesof atypical conditions, the south area of the southern part of the Kornati islands and the island of Žirje is ...very interesting for the thermohaline analysis. The analysis has not been completed,however, the activities necessary for getting an insight into justifiability and the need for radical interventions have been made. On the basis of the data obtained from longtime measurements, separate analyses of the sea water temperature, salinity and density have been made, defining annual courses of mean monthly and extreme values, mean monthly values at characteristic depths, and vertical distribution of mean monthly values. Special importance was given to external and internal influences.
The purpose of cartographic generalization is to represent a particular situation adapted to the needs of its users, with adequate legibility of the real situation and its perceptional congruity with ...the representation. Interesting are those situations which to some degree vary from the real situation in nature. This is purposeful generalization where attention is directed towards particular, thematically valuable objects and their details. Difficulties in accomplishment of the cartographic generalization objectives are reflected in the basic approach. Some cartographers encourage the idea of complete prevalence of subjective approach to the process, yet accepting partial solutions that enable automated data processing of certain chart elements. Others stand for objectifying of all procedures, or schematic solving of all issues in the process, which will gradually lead up to the level where it could be termed automated. The latter is considered more acceptable by the authors of this paper, implying the necessary human intervention in the generalization, yet not to determine the course of the process, but just to act as a mediator.
On the basis of climatological data (from 1911 to 1989) the authors have made the analysis of thermohaline values, their annual and vertical distribution in the Pag Bay and Velebitski channel, and ...also the analysis of synoptic data obtained from two oceanographic measurements in June 1989. The results show usual and nontypical conditions in the thermohaline structure in the water column. Explanation of phenomena are presented.
A methodological approach in the analyses of the seawater oceanographic states is determined by the purpose of the paper and general purpose of the research. In the recent decades the scientific work ...in this area has advanced thanks to computer data processing, particularly owing to modern technical and technological achievements that allow us to obtain important results, which significantly augment application of scientific results. This paper is a review of the research on the Central Adriatic shelf. Until now, papers dealing with geographical and oceanographic features regularly used the terms Palagruža Shelf and Jabuka concavity in the meaning of independent entities in the Adriatic basin which partly define physicogeographic features of water masses. However, such perception should be corrected. The Central Adriatic shelf is situated between the north Adriatic and the south Adriatic basin. Its length is greater than the width. Therefore, it deserves more attention and more cautious scientific approach. In this paper there are also evaluations of some methodologies used in the research and in the measuring of oceanographic parameter values, and also new technical solutions are proposed. The purpose of this paper is to analyse some methods of approach in the presentation of oceanographic states of seawater in the area of the Central Adriatic shelf. The purpose is also to introduce a succession of articles in which this maritime zone should be given its deserving significance from the geographic and oceanological aspects.
Teškoće u provođenju postupaka za održavanje pomorskih karata i navigacijskih publikacija (reambulacija u procesima hidrografskih organizacija) izravno utječu na usklađenost podataka na pomorskim ...kartama i navigacijskim publikacijama sa stvarnim stanjem u naravi. Ovaj je rad pokušaj doprinosa povećanju djelotvornosti reambulacijskih postupaka i u konačnici, višem stupnju točnosti dokumenata u izravnoj službi sigurnosti plovidbe. Predlažu se stanovite promjene u neposrednom terenskom radu koji obuhvaća akvatorij hidrografske izmjere, te u djelatnostima hidrografskih služba u izboru i obradama podataka iz reambulacija. Doprinos praksi svakako je određivanje odnosa reambulacije i hidrografske izmjere. Primjeren prostor posvećuje se razgraničenju redovitih reambulacijskih i izvanrednih postupaka.
U radu se pružaju odrednice tehnološkog razvoja u proizvodnji pomorskih karata i publikacija. Predviđaju se smjernice njihova razvoja. Pomorske karte i publikacije se od samih početaka drže ...jedinstvenima, i sadržanima u jednom proizvodu. S protokom vremena razdvajaju se na posebne cjeline - pomorske karte, te publikacije. Konačno se opet spajaju u jedinstven proizvod, tj. elektroničku kartu. U procesu se uočava točnost kao najvažnija osobina pomorskih karata i publikacija bilo kojeg oblika. Utvrđuje se njihova funkcijska povezanost s postupkom održavanja.
Termalne vrijednosti morske vode , njihov raspored, kolebanja, krajnosti itd., znanstveno je područje kojemu se pridaje dužno značenje i trajno zanimanje u fizičkoj oceanografiji. Važnost poznavanja ...ovog parametra velika je zbog potreba što potpunijih saznanja o utjecaju temperature na druge fizikalne, kemijske, biološke, i geološke parametre, te o njihovoj međuzavisnosti. U ovom radu analizira se termalno stanje u području, osobito važnom za odvijanje brojnih procesa u cijelom jadranskom bazenu, a posredno i u Sredozemlju. Procjenjuju se termalne značajke vodenih masa, tipična i netipična stanja , vodena dinamika, te utjecaj klimatski čimbenika na termalnu strukturu vodenog stupca. Analiza je poručila vrlo važne zaključke, od kojih jednomu valja obratiti pozornost, jer se takovu pojavu do sada nije uočilo. Radi se o uzdužnim termalnim valovima, odnosno o stanovitim zaprekama u vodenom stupcu. Istraživano područje povremeno presijecaju na vjerojatno šest, ili manje termalnih kanala. U slučajevima duljeg trajanja, ova bi pojava morala prouzročiti određene posljedice na živi svijet u moru, osobito planktonske organizme.

The thermal values of the seawater, their distribution, oscillations, extremes ect.., belong to the scientific field that has due importance and permanent interest in physical oceanography. The importance of understanding of this parameter is great, because of the need to complete the information about the influence of temperature to other physical, chemical, biological and geological parameters and their interdependence. This paper analyses the thermal state of the area, especially important for the course of numerous processes in the Adriatic, and inderectly in the Mediterranean. It estimates the thermal characteristics of water masses, typical and untypical state, water dynamics, and the influence of climatic actors to the thermal structure of water column. The analysis resulted in important conclusions, one of which has to be carefully considered, because such occurrence has not been observed yet. It refers to logintudinal thermals waves, or certain barriers in the water column. The researched area is occasionally cut to six or fewer thermal channels. In case of loger duration, this phenomenon should cause certain effects to sea organisms, especially to plankton organisms.
U radu se raspravlja o pojavi ispodpovršinskog minimuma slanosti u Jadranskom moru na temelju podataka dobivenih tijekom istraživanja provedenih između 1972. i 1985. godine. Utvrđeno je da se proces ...tonuća manje slane površinske vode odvija u cijelom jadranskom bazenu, da duboka jadranska voda ima autohtono porijeklo te da sezonski redovito sudjeluje u vodoizmjeni sa Sredozemljem.
