BALTIC SEAENVIRONMENT PROCEEDINGS No. 59 - Helcom

Environment Bibliography obtains much of the material directly from authors, institutes and
libraries and to a lesser extend from the monitoring journals and serials, which is the main method
in case of large international databases. This means that the content of the Baltic Marine
Environment Bibliography is unique and as such it is an important source of information for
marine researchers and completes the information received from other information sources.
The subject coverage includes all aspects of the marine environment of the Baltic Sea, for example
ecology, fauna and flora, fisheries, hydrography, pollution, environmental impact,
research, planning and administrative measures. Noticeable part of references deal with pollution
problems. They cover nearly 40 % of the references.
The main language of the documents is English (46 %). Other languages include for example
Swedish (13%), Russian (10 %) and German (10 %). 44 % of the original documents are journal
articles, 31% are monographs and 25 % are monograph chapters.
All references have the title and keywords in English. From the year 1990 abstracts have been
added to the bibliographic references. References are also augmented by classification codes. For
the material since 1980 the classification and thesaurus of the Aquatic Sciences and Fisheries
System, ASFA of FA0 have been used. In the earlier phase an own classification system was
used.
How the original documents can be obtained?
The original documents are deposited in officially nominated contact libraries in every Baltic Sea
state. The documents can be ordered as loans or photocopies trough local scientific libraries from
the contact libraries.

Kattegat
The recurrence of various agents of fine sediment resuspension in
the Kattegat Sea, notably wind-induced wave action and demersal
trawling, and their seasonal variation and long-term trends have
been estimated. A comparison between the sediment-water interface
and the spatial distribution of theoretical wind/wave impact
indicated that the sediment is resuspended by further agents at
depths below the permanent halocline between 10 and 20 m depth. The
climatic deterioration in 1940-70 had a significant influence on
the recurrence of wind-induced resuspension, although this was
mostly limited to a lo-30 degree shortening of the recurrence
period. On the other hand, a quantification of the effect of
demersal trawling in the same period suggests a total shortening of
recurrence at bottoms below the halocline by 75-85 degree in the
autumn and winter, and with one order of magnitude (90 degree) in
spring and summer, compared with the effect of waves only in the
1930s; resuspension caused by near-bottom unidirectional currents
was not quantified. At these deeper bottoms, resuspension
conditions have approached those prevailing at shallow bottoms
above the halocline.
