soil types, whereas the combinations of NUTS2 regions and Environmental zones
generally are continuous areas. The OCTOP used in the definition of the Seamzones,
is a function of ESDB soil types, temperature and land cover. The methodology
used to compile the OCTOP database resulted in this spatial pattern. In Fig.
7.3
the scattered distribution of a Seamzone (dark) is illustrated for Sicily in Italy.
Sicily is a NUTS2 region in the MDM, MDN and MDS EnZs with a total of 16
Seamzones. The Seamzone presented in dark is a combination of the NUTS2
region Sicily, MDS EnZ and OCTOP class two (see Fig.
7.3
). The map also
illustrates that the processing of data for the Seamzones was done at a one km
grid, so that the smallest units are 100 ha (an exemption from this is along
coastlines, where the actual coastline is used). For all 3,513 Seamzones the
average number of scattered areas is 162. Ten percent of the Seamzones consists
of four or less subareas, half of the Seamzones of 58 or less sub areas and 90%
of the Seamzones of 398 or less subareas. The maximum number of subareas
within a single Seamzone is 4,322 (Table
7.4
).

The spatial pattern of the 16 Seamzones on Sicily, Italy. As an example the Seamzone
(NUTS2: region Sicily, EnZ: Mediterranean South, OCTOP class: 1.23-2.46%) indicated with the
grey colour includes 692 areas scattered across the island. The other lines in the map are borders
between the other Seamzones (white areas)
