The purpose of this journal is to provide a medium of exchange for those engaged in marine research where there exists an interplay between geology, chemistry, biology, and physics. The Journal of Marine Systems therefore welcomes original and state-of-the-art contributions on all aspects of marine sciences. Preference is given to papers which extend beyond the limit of a single discipline and which follow the rationale of system analysis. Journal of Marine Systems is available as part of the Oceanography Package - Option 1 which comprises Continental Shelf Research, Deep Sea Research Parts I & II, Journal of Marine Systems, Marine Models Online, Ocean and Atmospheric Data Management, Oceanographic Literature Review and Progress in Oceanography. See Oceanography Package - Option 1 for details. Journal of Marine Systems is also available as part of the Oceanography Package - Option 2 which comprises the eight journals in Oceanography Package - Option 1 along with Marine Literature Review CD-ROM.
