| Zusammenfassung |
| A new water mass analysis technique is used to analyse the BATS
oceanographic data set in the Sargasso Sea of 1988–1998 for changes in
Labrador Sea Water (LSW) properties. The technique is based on a sequential
quadratic programming method and requires careful definition of constraints
to produce reliable results. Variations in LSW temperature and salinity
observed in the Labrador Sea are used to define the constraints. It is shown
that to minimize the residuals while matching the observed temperature and
salinity changes in the source region the nitrate concentration in the
Labrador Sea has to be allowed to vary as well. It is concluded that during
the period of investigation nitrate underwent significant variations in the
Labrador Sea. |
