mid and bottom sensor until the beginning of January, when a temperature rise was noted
by all three sensors. Between mid January and mid March daily temperature records of all
three current meters were quite similar, whereas the highest variability appeared in 178 m and
near the bottom temperatures were almost homogeneous. By mid/end of March a rise in
temperature of all three current meters was recorded.
Comparing hourly values of mooring NE's current directions with the directions of mooring SE,
it is noticeable that mooring NE's current directions are not as a stable as directions of mooring
SE. Although the general direction of currents measured by NE was north, alternating between
northeast and northwest (see Fig. 5.2 in the appendix). Changes to southerly directions
occurred more often than in mooring SE. Two pronounced events with high current speeds are
noteworthy, the rst on the 3 November 2006 with speeds between 25 cm/s and 30 cm/s and
the second at around mid-end of January 2007 with speeds of around 25 cm/s. Before the
increase in January 2007 speeds were on average around 10 cm/s, afterwards slightly higher.
In general current speeds were far more varied and not as homogeneous as in mooring SE and
changes in direction seemed to occur in pulses.
