measures
For  reasons  of  feasibility,  most  investigations  concentrate  on  representative  main  research
areas  and  are  made  on  different  spatio-temporal  scales  depending  on  the  phenomena
concerned,  i.e.  topographic  studies  at  intervals  of  several  years,  and  seasonal  processes  several
times  a  year.  In  keeping  with  the  interdisciplinary  approach,  a  wide  variety  of  different
methods  are  used,  ranging  from  aerial  to  field-biological  surveys.
Products  and  services
The  products  are  reports  on  individual  subjects  which  also  include  charts.  A  data  base
containing  most  of  the  relevant  information  is  currently  being  developed.  Data  holding  will  be
decentralized,  so  that  information  can  be  retrieved  regionally  for  the  area  of  Lower-Saxony  or
for  the  tidal  flats  areas  of  Hamburg  and  Schleswig-Holstein.  Access  via  the  World  Wide  Web
(WWW)  will  be  possible,  and  realization  is  scheduled  for  1999.  A  precursor  is  the  EU  funded
DEMOW  AD  module  which  has  been  operationalized  as  a  prototype.

The  activities  of  LANU  SH  are  listed  in  the  attached  Table.
The  programmes  are  implemented  using  the  results  of  the  BLMP  contribution  of  Schleswig-Holstein
  for  the  North  Sea  and  Baltic  Sea.  The  objectives  correspond  to  those  listed  in  the
BSH-P1  programme  under  1)  to  4).
