On our way from Saint Petersburg back to the Skagerrak (Skaw) today we
were
off Gotland again. When we passed it on Apr 30th, we
visited
58°N/19°E, but for 57°N/18°E it had been still too dark
then.
This time there was chance for this point, which we
were
approaching from the North. When we were abeam of the small Island Stora
Karlsö, we went on a course of 177° towards the
confluence.
The coast is full of wind rotors, in front we
see
the small lighthouse of Näsrevet.
Then we proceeded to the confluence, from where we could see the church
of
Burgsvik. Burgsvik is the closest settlement
to
the confluence and is a small harbor, where limestone is loaded. It has
a
population of about 300.
In the area off the Burgsviken (Gulf of Burgsvik) there are many wind
rotors some of them even built into the sea.
Please have a closer look to these wind rotors on the Radar screen. The rotors in the sea are orientated as a triangle according
to
the directions from where the wind predominantly is blowing in this
area,
i.e. from North and from 55° (roughly NE), in order to gain a maximum
output.
The Southern end of Gotland Islands is called Revet.
This was quite an interesting confluence, and provided with new
knowledge
about Gotland's electric power generating system we are proceeding
further.
