Summary: A method of computing the exchange time of freshwater and
marinewater in a stratified estuary is presented. The method is basedon the
inflow of the river and its tributaries, the depth of thehalocline and
salinity in the upper brackish water layer. Duringwinter the exchange time
of freshwater in Krka estuary is between6 and 20 days, whereas during
summer it is up to 180 days. Therenewal time of water in the Krka estuary
as a whole may beapproximated by the exchange time.
Keywords: exchange time, residence time, stratified estuary, Krka

Summary: Before the onset of wind in the Krka estuary, a sharp
haloclineextends from 2.5 to 4 m below the surface, separating the
upperbrackish water layer from the lower marine layer. Strong wind (20m/s)
induces a tilt of the halocline surface so that downwind (5km wind fetch)
the halocline is pushed to 4.6 m below thesurface. Wind driven currents
induce a vertical gyre within theupper layer and a gyre in the opposite
direction in the lowerlayer. The role of wind induced oxygenating of the
bottom layeris discussed.
Keywords: wind, stratified estuary, halocline, hypoxia, vertical mixing

Summary: Current and temperature data, taken during 1986 and 1987 in
theKrka estuary (east Adriatic coast), are analysed for evidence
ofhigh-frequency oscillations. The spectra computed from data showpeaks
corresponding to periods of 2.8 h and 45 min. Analyses ofthe 45 min reveal
that these oscillations occur intemittently.They probably represent
internal waves travelling down theestuary. The waves appear to be generated
by the interaction ofthe second-order surface seiches with topography. The
system ofcoupled surface seiches and internal waves may be either of
localmeteorological origin or externally forced at the mouth of theestuary.
Keywords: seiches, internal waves, stratified estuary, Krka estuary

Summary: A subsurface temperature maximum recorded in the
highlystratified Krka estuary is described. The maximum is located onthe
lower edge of a steep halocline and reaches the highesttemperature in the
Adriatic Sea. Temperatures of up to 31 oC wererecorded. The development of
the maximum and its persistenceduring summer is the consequence of a
relatively thin transparentbrackish layer while the entrainment of the
seawater is weak. Themaximum may be recorded from the middle of April until
the end ofOctober. Following consequences are discussed: effect on
verticalmixing across the halocline, effect on equilibrium of
chemicalspecies and on decomposition rate of freshwater phytoplankton.
Keywords: temperature maximum, stratified estuary, Krka estuary

Summary: Individual surface-active particles (SAP) in
aqueousenvironmental samples can be categorized through coalescence
withmodel hydrophobic interface. Each coalescence event is recordedas an
electrical signal. As the signal is a current transient,the sequence of
fast processes leading to the formation of acondensed film can be studied.
In Krka estuary, SAP are present in the maximum concentrations atthe
halocline ( 10**7 to 5*10**8 particles/l of size >1 um).Particles can be
viewed as oily droplets. Discussed are processesleading to formation of
organic films and and accumulation ofmercury at the halocline.

Summary: Nutrients, chlorophyll a, primary production and
standardoceanographic parameters were measured seasonally from 1983 to1988
along the axis of a karstic estuary of the central AdriaticSea (Krka
estuary). Because of anthropogenic phosphorusdischarges, the surface-layer
orthophosphate concentrations (upto 1.7 mmol/m**3), phytoplankton biomass
and primary productionwere significantly higher in Šibenik Bay than in
other estuarinesubregions and the coastal sea. Effects of introduction
ofnitrogen and silica are also discussed. It is concluded thatanthropogenic
nutrient inflows should be reduced to re-estabilisha natural nutrient
environment.

Summary: The occurence of hypoxia in October 1988 in the Krka
estuary isdescribed with special reference to Prokljan Lake.
Hypoxiadevelops near the bottom in autumn in response to the
temperaturemaximum that appears this time of the year. The
decompositionrate of naturally present organic matter increases,
creatinghigher biological oxygen demand. When an extensive
marinephytoplankton bloom appears below the halocline in Prokljan
Lake,dissolved oxygen near the bottom decreases further. The hypoxiamay be
so severe that it causes massive mortality of benthicmacro fauna. In the
absence of rains and a slow exchangerate of water, hypoxia may be recorded
throughout the winter.
Keywords: hypoxia, stratified estuary, Krka estuary

Summary: A subsurface bloom of the marine dinoflagellate
Gonyaulaxpolyedra Stein was observed in October 1988 in the central partof
the Krka estuary (east Adriatic coast) as a 6 m thichred-brownish layer,
located below the halocline. The bloom mighthave been initiated by the
excystment in the shallower part ofthe estuary, where temperature near the
bottom exceeded 20 oC.The autumn of 1988 was exceptionally dry, river flow
was smalland the brackish layer was 2 m thich an transparent. The supplyof
nutrients for growth came from sinking and decomposition offreshwater
phytoplankton at the halocline and in the marinelayer.

thecharacterization of the initial steps of organic monolayerformation at a
fluid interface: mercury/aqueous dispersion ofinsoluble surfactants. The
attachment of the organic film to theelectrode substrate through the

convenient in situtechnique for the preparation and investigation of
organic ororganometallic films.

Summary: The effect of S-adlayer preparation on the voltammetric
behaviourof self-assembled monolayers of the heteroaromatic
moleculesthionine and methylene blue was studied by varying the
S-adatomconcentration at the polyoriented platinum electrode from zero

Phenothiazines can be used as redox probes for S-adlayers in therange of
S-adatom concentrations where the classicalelectrochemical approach is
insensitive.

bromides,substituted with electron-withdrawing and electron-donatinggroups,
was investigated at tin cathodes. A new electroanalyticalmethod for

Summary: The distribution of total dissolved trace metals (Pb, Cd,
Cu, Niand Fe) in the Krka river estuary was studied in May 1988 duringhigh
productivity period. The dissolved metal concentrations inthe freshwater
end-member are the same order of magnitude asthose observed in unpolluted
rivers of the world and are inaccordance with the carbonate nature of the
catchment of the KrkaRiver which is located in the national park.

anddissolved inorganic carbon were measured seasonally from 1987 to1989 in
the Krka estuary. Carbon inputs by the river are low. Theaccumulation of

Summary: The detailed distribution of algal chlorophyll and
carotenoidpigments was determined around the halocline
(freshwater-seawaterinterface) in the Krka estuary on the east coast of the
AdriaticSea in May 1988. The higher concentration of chl a were found inthe
interfacial layer off the city of Šibenik where high inputsof nutrients
supported the accumulation of living algae at thehalocline. Discussed are
also: alloxanthin, chl b andpheophorbides.

Summary: The interaction of the methylene blue (MB+) molecules with
thesurface of Hg electrode has been investigated using
purelyelectrochemical methodology. The interaction of MB+ molecules
wasfound to be so strong that the redox signal of the innermonolayer is
well separated from the signal of overlayingmolecules as in the case of
underpotential deposition of metallicphases.
The phase transition during the redox change in the innermonolayer is
analyzed according to BFT model for 2Delectrocrystallization.

and anodicstripping voltammetry.

hexadecene,1-heptadecene, squalene and methyl oleate).
