Abstract

The purpose of the paper is to point out a few hydrographical features of the Baltic Sea, which make this sea, in reference to the disposal of radioactive wastes, different from any oceanic region. The seas can be divided, in reference to the practical problem of the disposal of radionuclides, into the following zones: (1) harbours, (2) fairways leading into harbours, (3) outer continental shelf and (4) the open sea. There, is no open sea, in the above sense, in the Baltic Sea. In addition, the validity of the rules recommended for the above zones, must be carefully checked through further hydrographical studies, since: (1) the whole Baltic is, in a sense, an estuary, with a sill-depth of only 18 metres in the Danish Sounds, (2) the mixing in the Baltic Sea is much more restricted than in the oceans, since the Baltic is rich in islands, brackish, heavily stratified, practically tideless, in winter partly covered with ice, and has a limited fetch of wind and only slowly moving permanent currents. In the paper reference is made to all these factors which diminish the turbulent diffusion, both vertical and horizontal. For the evaluation of the advection and turbulent (eddy) diffusion,  More>>

abstractNote = {The purpose of the paper is to point out a few hydrographical features of the Baltic Sea, which make this sea, in reference to the disposal of radioactive wastes, different from any oceanic region. The seas can be divided, in reference to the practical problem of the disposal of radionuclides, into the following zones: (1) harbours, (2) fairways leading into harbours, (3) outer continental shelf and (4) the open sea. There, is no open sea, in the above sense, in the Baltic Sea. In addition, the validity of the rules recommended for the above zones, must be carefully checked through further hydrographical studies, since: (1) the whole Baltic is, in a sense, an estuary, with a sill-depth of only 18 metres in the Danish Sounds, (2) the mixing in the Baltic Sea is much more restricted than in the oceans, since the Baltic is rich in islands, brackish, heavily stratified, practically tideless, in winter partly covered with ice, and has a limited fetch of wind and only slowly moving permanent currents. In the paper reference is made to all these factors which diminish the turbulent diffusion, both vertical and horizontal. For the evaluation of the advection and turbulent (eddy) diffusion, both in the upper water layers and at the bottom, synoptic observations of current velocity and salinity at a number of points in several regions of the Baltic Sea and under different weather conditions are needed. (author) [French] Le memoire a pour but d'exposer certains traits de l'hydrographie de la mer Baltique qui, du point de vue de l'evacuation des dechets radioactifs, la distinguent de toute region oceanique. Pour l'etude des problemes pratiques poses par l'evacuation des dechets radioactifs, on peut repartir la mer en quatre zones: 1) les ports, 2) les chenaux d'acces aux ports, 3) le plateau continental, 4) la haute mer. Dans ce sens, il n'y a pas de haute mer dans la Baltique. En outre, la validite des reglements recommandes pour les zones precitees doit faire l'objet d'une verification approfondie au moyen d'etudes hydrographiques plus poussees, etant donne que: 1) Toute la Baltique est, en un sens, un estuaire, avec une profondeur de seuil qui ne depasse pas 18 metres dans les Detroits. 2) Le brassage y est beaucoup plus reduit que dans les oceans, pour diverses raisons: nombreuses iles, eau saumatre, stratification marquee, pratiquement pas de marees, mer partiellement recouverte de glace en hiver, peu de parcours pour les vents, faible vitesse des courants permanents. Le memoire mentionne tous ces facteurs qui diminuent la dispersion par turbulence, tant verticale qu'horizontale. Pour evaluer la dispersion par advection et par turbulence, tant dans les couches superieures qu'au fond de la mer, il faudrait faire des observations synoptiques de la vitesse des courants et de la concentration saline en un certain nombre de points' situes dans plusieurs regions de la Baltique et dans diverses conditions atmospheriques. (author) [Spanish] La memoria tiene por finalidad describir algunas caracteristicas hidrograficas del Mar Baltico que hacen que este mar, para la evacuacion de desechos radiactivos, sea diferente de las demas regiones oceanicas. Para la evacuacion de radionuclidos pueden distinguirse, en la practica, las siguientes zonas maritimas: 1) puertos; 2) vias de acceso a los puertos; 3) plataforma continental exterior, y 4) alta mar. En este sentido, no existe alta mar en el Baltico. Ademas, la validez de las normas recomendadas para estas cuatro zonas debe verificarse cuidadosamente con nuevos estudios hidrograficos, ya que: 1) Todo el Baltico es, en cierto modo, un estuario, cuya profundidad es de solo 18 metros en los estrechos daneses; 2) La velocidad de mezcla en este Mar es mucho menor que en los oceanos, pues el Baltico: tiene muchas islas; es de escasa salinidad; es muy estratificado; carece practicamente de mareas; en invierno queda parcialmente cubierto de hielo; solo registra vientos debiles; no tiene corrientes continuas mas que de escasa velocidad. En la memoria se examinan todos estos factores que reducen la difusion turbulenta, tanto vertical como horizontal. Para evaluar la conveccion yla difusion turbulenta, tanto en las capas superficiales como en las profundas, es preciso efectuar observaciones sinopticas de la velocidad de las corrientes y de la salinidad de las aguas en numerosos puntos de distintas zonas del Baltico y en diferentes condiciones meteorologicas. (author) [Russian] Cel' dannogo dokumenta ukazat' neskol'ko gidrograficheskih osobennostej Baltijskogo morja, kotorye otlichajut jeto more v tom, chto kasaetsja udalenija radioaktivnyh othodov, ot ljubogo okeanicheskogo rajona. S tochki zrenija prakticheskoj problemy udalenija radioaktivnyh izotopov, morja mozhno razdelit' na sledujushhie zony: 1) gavani, 2) farvatery, vedushhie k gavanjam, 3) vnekontinental'nyj shel'f, 4) otkrytoe more. V svete vysheizlozhennogo, Baltijskoe more ne javljaetsja otkrytym morem. Krome togo, neobhodimo tshhatel'no proverit' s pomoshh'ju dal'nejshih gidrograficheskih issledovanij obosnovannost' pravil, kotorye rekomendovany dlja vysheupomjanutyh zon, tak kak 1) vse Baltijskoe more javljaetsja v nekotorom smysle ust'em, glubina kotorogo do poroga sostavljaet tol'ko 18 metrov v Datskih prolivah, 2) obrazovanie smesi v Baltijskom more bolee ogranichenno, chem v okeanah, tak kak Baltijskoe more bogato ostrovami, solonovatoe, s bol'shimi nasloenijami, fakticheski ne imeet prilivov i otlivov, zimoj chastichno pokryto l'dom i imeet neznachitel'nye vetry, imeet tol'ko medlennoe postojannoe techenie. V dannom dokumente ukazyvajutsja vse jeti faktory, kotorye snizhajut kak vertikal'nuju, tak i gorizontal'nuju turbulentnuju diffuziju. Dlja opredelenija advekcii i turbulentnoj (vihrevoj) diffuzii kak v verhnih vodnyh slojah, tak i na dne, neobhodimo imet' sinopticheskie dannye o skorosti techenija i o solenosti v rjade punktov v neskol'kih rajonah Baltijskogo morja i pri razlichnoj pogode.
