Opis:
An experiment has been performed to determine the upward water-leaving radiance by non-contact measurement of the total upward and downward radiance above the sea surface from a moving ship. The method for achieving this aim is described: the radiance meters are both tilted in such a way that the upward radiance meter can ‘see’ that part of the measured downward radiance which would be reflected if the water surface were smooth and which is not derived directly from solar glitter. Both meters are firmly fixed in a special frame, which ensures that the required orientation is the most probable one. Time records of the measured parameters are analysed. The results are presented in several forms: frequency (histogram) analysis appears to be the most promising one.

Opis:
Global warming is an important and popular subject across global communities and in a wide array of literature. Global weather patterns are becoming more violent with an increase in the number of catastrophic events. The fundamental concepts of climate are strongly related to the natural freezers on planet Earth. Global warming affects Earth’s natural ice freezers. The warming climate in the Arctic and Antarctic regions are causing an increase in the melting of glaciers, which in turn generates a rise in ocean levels. The rising water levels are causing major regional problems in coastal areas and more importantly they are further accelerating global warming and extreme weather effects. This paper examines the long-term warming of the Arctic and Antarctic regions and the long-term rising water levels in the oceans, in addition to making predictions of these trends for the upcoming decades.

Opis:
An original method for estimating the concentration of chlorophyll pigments, absorption of yellow substance and absorption of suspended matter without pigments and yellow substance in detritus using spectral diffuse attenuation coefficient for downwelling irradiance and irradiance reflectance data has been applied to sea waters of different types in the open ocean (case 1). Using the effective numerical single parameter classification with the water type optical index m as a parameter over the whole range of the open ocean waters, the calculations have been carried out and the light absorption spectra of sea waters tabulated. These spectra are used to optimize the absorption models and thus to estimate the concentrations of the main admixtures in sea water. The value of m can be determined from direct measurements of the downward irradiance attenuation coefficient at 500 nm or calculated from remote sensing data using the regressions given in the article. The sea water composition can then be readily estimated from the tables given for any open ocean area if that one parameter m characterizing the basin is known.

Opis:
Today, the global conveyor belt of ocean currents is controlled by the configuration of continents and the climate. Conversely, ocean currents influence water and air temperatures as well as the amount of rainfall on a regional to local scale. In addition, they govern species distribution patterns, sedimentation patterns and the dispersal of nutrients in both oceans and epeiric seas. Therefore, the reconstruction of palaeocurrents is crucial for the understanding of ancient environments and the past climate. An important driver for the global ocean circulation is the formation of deep water. However, deep-water production is difficult to estimate, and its circulation is difficult to reconstruct, not only today but especially in the geological record. Palaeocurrent reconstructions are often based on the temporal and spatial distribution of marine species. In this presentation, a new approach is proposed which uses the occurrence of glendonites as a proxy for cool bottom currents. Glendonites are pseudomorphs after the hydrous carbonate mineral ikaite (CaCO3·6H2O) which only forms in environments characterised by near-freezing temperatures. Throughout the Phanerozoic, glendonites can be found in successions which were deposited in high latitudes. However, examples of glendonite occurrences in mid-latitudinal sections are also reported. One of these examples are upper Pliensbachian (Lower Jurassic) glendonites from a shallow-marine succession in South Germany which was located in the European epicontinental sea  – an area, where it was technically too warm to form the precursor mineral ikaite. Based on petrographical and sedimentological investigations as well as stable isotope analyses it is concluded that a low temperature was the main factor for ikaite formation in the studied section. To explain the low water temperatures, a model for a thermohaline circulation in the European epicontinental sea is proposed. The cool climate in the late Pliensbachian initiated the growth of sea ice in high latitudes, leading to the formation of cold and saline bottom waters analogous to the modern formation of North Atlantic Deep Water (NADW) and Antarctic Bottom Water (AABW). The cold bottom current flowed southward from the Arctic Realm through the Viking Corridor into the European Epicontinental Sea, thereby causing a massive cooling of the deeper parts of the epeiric sea, which led to the formation of ikaite in temperate areas. After passing the shelf, the bottom current entered the Western Tethys, probably forming a deep water mass. The proposed model can help to explain mid-latitudinal glendonite occurrences not only in the Pliensbachian, but also in other areas and time slices which are characterised by cooling. Moreover, it enables the use of the pseudomorph as a tracer for cold bottom currents which can be a helpful tool for the reconstruction of global ocean current patterns.

Opis:
One of the complexities of the ocean currents in the territorial waters of Indonesia is oceanic eddies form. Ocean eddy is one of the very crucial phenomena in the ocean due to its circulation and connection with the chemical and biological aspects in the water column. This study aimed to observe the distribution of oceanic eddies associated with the Sea Surface Temperature (SST) and Sea Surface Height (SSH) with the Automatic Eddy Detection (AED) method. The analysis included distribution and types correlated with seasons. The results showed that eddies occur in all regions in the Indonesian Seas except the Java Sea. In general, the occurrence of eddies every month does not differ significantly for both Ocean Cyclonic Eddies (OCE) and Ocean Anticyclonic Eddies (OAE). The total oceanic eddies in a year are around 1,149 events. A minimum radius of the ocean eddies found was about 5.08 km, and a maximum was around 386.76 km. Furthermore, the occurrence of OCE is mostly in locations that are almost the same as OAE. Both types of eddy are mostly in locations with the boundary of temperatures and the boundary of SSH. Several eddies exist every month and mostly change or move into other areas. Eddies in Indonesia seas are influenced by differences of SST and different SSH that form ocean currents.

Modeling of ship motions in waves concentrates in most applications on the response amplitude operator (RAO). This mathematically not demanding method of analysis is very attractive, but loses some essential information in certain situations. The objective of present contribution is to establish and investigate preliminary foundations for a seakeeping model as optimal for under keel clearance (UKC) estimation. A special attention was devoted to transients of motions, stationary harmonic motions, coupling between degrees of freedom, and the wave force transfer functions – all in the aspect of shallow water environment.

Opis:
Geographical words referring to water, such as river, stream sea or lake, have been used in language since the earliest. As water is considered essential for life in general, the names of water reservoirs and watercourses became popular and frequently used items in all languages. The present study is focused on the English names of natural water reservoirs (sea, lake) and watercourses (river, stream) and their regional spread in the 12th–15th centuries. The Old English names of watercourses and natural water reservoirs, sӕ, flod and ea, either survived in Middle English in a modified form or were (rarely) replaced by loanwords as the effect of the Norman Conquest of England in the 11th century. The research is concentrated on texts selected from the Innsbruck Corpus of Middle English Prose (Marcus 2008), with some material coming from the OED and MED. The analysis will show the extent of the loss of the original Anglo-Saxon words or their spread, frequently with a modified meaning. The analysis will also include the statistics of the terms in question in prose texts representing the chief dialects of the period. As regards the method, the present author makes use of the traditional semantic theories (e.g. Lyons 1977) and the prototype theory (e.g. Geeraerts 1997).

Opis:
The factors influencing the atmosphere-ocean transfer of mass and momentum, as well as incipient wave breaking and the amount of energy dissipated due to breaking, are discussed in detail. In particular, the influence of directional spreading on the statistics of surface wave slopes and the area of the wind- roughened ocean surface is demonstrated. Theoretical analysis and comparison with the available experimental data show that unimodal directional spreading is not able to reproduce the observed ratio of the cross-wind/up-wind mean square slopes. Better agreement is achieved when bimodal directional spreading, consisting of two wrapped-Gaussian distributions, is applied. The bimodal form suggested by Ewans (1998) is used in the paper. Moreover, the formulae developed here show that the increase in the area due to surface waves is rather small for both regular and irregular waves.

Opis:
The motion of water due to surface waves is the most dynamic factor observed in the marine environment. In this review various aspects of the wave modelling of non-linear, steep surface waves and their role in the atmosphere-ocean interaction are discussed. Significant improvements in wave forecasting have been made in the last ten years. This is to a large extent related to substantial progress in the description of wind forcing and other processes, as well as to the more efficient use of satellite observations and assimilation methods. One striking observation is the increasing variety and complexity of models in which more physical processes are implemented, greater precision and resolution achieved and extended ranges of applicability demonstrated. However, in order to evaluate the applicability of particular models, comparison with high quality experimental data, collected in nature or under laboratory conditions, is necessary.

Opis:
Comprehensive knowledge and modern technique make it possible to reach for different natural resources deposited in water or on oceans bottom or even in stratum below the bottom. World ocean takes over 71% of our globe and considering continuous shrinking of natural resources of raw materials and fuels it becomes nowadays the area of intensive geological exploration. Having in mind the fact that most of typical land resources of useful minerals will last at the very most 50÷200 years, adequate reserves laying down at the bottom of the world sea may give our civilization a chance for several thousand years' development, according to scientist calculations [14]. Taking above into consideration, all seas and oceans shelves were divided into plots and fields. Many shelves are explored nowadays concerning petroleum and natural gas and such output reaching the level of 20% of total production [5]. Basing on different research and exploration it was found that the bottom and under bottom resources of natural minerals are gigantic. Technological development as well as huge investments caused that this XXI century starts new beginning of oceans exploitation [15] and its conquest. Careful investigations especially of deep resources exploration still is future matter. However nowadays there are rich useful minerals areas deposited at the bottom in the form of poly-metallic concretions. These are o res in the form of nodules including metals e.g.: manganese, cobalt, copper, iron and nickel. Among six different areas rich in concretions, the most perspective one is Clarion-Clipperton where such minerals concentration exceeds 10 kg/m2 [9]. This area region is located at Pacific in equatorial zone including undersea bottom leap down at the level range of 4200 to 5200 m [12]. Since 1992 Poland as so called investing pioneer (representing international organization Interocenametal) has the right to explore plot in the range of mentioned Clarion-Clipperton region of area of 150.000 km2 [7]. This paper presents basis of unconventional technology of poly-metallic concretions output by application of high-pressure cavitation water jet [1] with addition of dry ice particles CO2 as a medium helpful for material loosening form the ground. Such ice particle resistance to hygroscopicity causes that it doesn't have tendencies for lumping and therefore it may keep predicted ability for sublimation. Adequate intensity of this phenomenon [3, 4] in conditions analogical to those existing down at the sea bottom proceeds in a long time [7]. Considering above the gas form of CO2 may cause proper draught of water flow in elastic transportation pipeline. In turn for vertical transport intensification there is need to use additional air injector.
W pracy scharakteryzowano konkrecje polimetaliczne zalegające dno oceaniczne oraz ich zasoby i miejsca występowania, zwłaszcza w przyznanym Polsce obszarze pomiędzy uskokami dna pacyficznego o nazwie Clarion-Clipperton. Przeanalizowano metody ich wydobywania w obszarze głębokomorskim a zwłaszcza hydraulicznego transportu urobku z dna oceanu na pokład statku górniczego. Przeanalizowano możliwość zastosowania wysokociśnieniowej strugi wodnej wspomaganej fizycznym oddziaływaniem cząstek suchego lodu CO2. Wskazano na bardzo przydatne cechy tego lodu, dzięki którym jego cząstki nie podlegają zbrylaniu natomiast sublimują w strefie urobku. Powstające duże ilości gazowej fazy CO2 zwiększają dynamikę pionowego przepływu płynu w przewodzie rurowym, co zwiększa skuteczność transportu urobku na powierzchnię. Jednak dla zapewnienia odpowiedniej wydajności pionowego transportu konkrecji polimetalicznych należy na określonej głębokości wtłaczać do rury sprężone powietrze. Przedstawiono w nim podstawy transportu metodą iniekcja pneumatycznej opracowane dla optymalnego wydobywania konkrecji polimetalicznych. Przeanalizowano struktury przepływów występujących w różnych przekrojach rury transportowej oraz określono ich teoretyczne zależności. Opracowano również wzory pozwalające na dokonywanie wyboru najważniejszych parametrów decydujących o skuteczności tej metody.

Opis:
The standard exponential model for CDOM absorption has been applied to data from diverse waters. Absorption at 440 nm (ag440) ranged between close to zero and 10 m−1, and the slope oft he semilogarithmic absorption spectrum over a minimum range of400 to 440 nm (s440) ranged between <0.01 and 0.04 nm−1. No relationship was found between ag440 or s440 and salinity. Except in the southern Baltic, s440 was found to have a broad distribution (0.0165 ± 0.0035), suggesting that it should be introduced as an additional variable in bio-optical models when ag440 is large. An alternative model for CDOM absorption was applied to available high quality UV-visible absorption spectra from the WisGla river (Poland). This model assumes that the CDOM absorption spectrum comprises distinct Gaussian absorption bands in the UV, similar to those ofb enzene. Five bands were fit to the data. The mean central energy ofal l bands was higher in early summer (E ∼7.2, 6.6, 6.4, 6.2 and 5.5 eV or 172, 188, 194, 200 and 226 nm) than in winter. The higher energy bands were found to decay in both height and width with increasing salinity, while lower energy bands broadened with increasing salinity. s440 was found to be correlated with shape parameters of the bands centred at 6.4 and 5.5 eV. While the exponential model is convenient for optical modelling and remote sensing applications, these results suggest that the Gaussian model offers a deeper understanding ofc hemical interactions affecting CDOM molecular structure.

Opis:
The water masses in Fram Strait have been analyzed on the basis of hydrographic casts taken in summer 1984 during the MIZEX 84 experiment. In particular, θ − S diagrams for 16 areas, each 5◦ in longitude and 1◦ in latitude, covering the strait from 77◦N to 81◦ N are used to characterize the water masses and discuss their possible origin. Near the surface, the East Greenland Polar Front clearly separates the lighter, cold and fresh Polar Water (PW) from the heavier, warm and saline Atlantic Water (AW). In the upper ocean, the data show a large spreading of the temperature maximum in the θ − S space associated with different modes of the AW recirculating southward below the PW. Two geographically distinct salinity minima are found in the intermediate layer below the AW. The denser one, in the Boreas Basin, is a feature typical of the Arctic Intermediate Water (AIW) formed by winter convection to the south of the strait, while the lighter one is sandwiched in the Arctic Ocean outflow between the AW layer and the Upper Polar Deep Water (UPDW) characterized by a downward salinity increase. In the deep layer, two salinity maxima are present. The shallower (and warmer) one, associated with the Canadian Basin Deep Water (CBDW), appears all along the East Greenland Slope. A similar but weaker maximum is also found in the southeastern part of the strait. This maximum is perhaps a remnant of the maximum in the East Greenland Current after it has been recirculated back to the strait around the cyclonic gyres of the Nordic Seas. The deeper one appears typically as a near-bottom salinity jump characteristic of the Eurasian Basin Deep Water (EBDW). The jump is found in two distinct areas of the strait, to the north-west in the Lena Trough and to the south-east in the rift valley of the Knipovich Ridge. The maximum in the former area should have been advected from the Arctic Ocean below the CBDW, while the maximum in the latter area might have originated from haline convection on the adjacent shelves. Some EBDW is trapped in the Molloy Deep over a denser water with salinity decreasing down to the bottom and temperature in the range of the Greenland Sea Deep Water (GSDW).
