At least the centre of the Black Sea has seen a decrease in both water
temperatures and
salinity since 1920 -- when the first records appeared in the World
Ocean Database.
The graphs are here:

(If your ISP or specific IP is associated with unsolicited mail or
other suspicious activities in
some database somewhere then you'll get a 404 from my ISP).
The data for all annual avg of the WOD entries for each year over the
2 deg x 2 deg box
centred at the middle of the Black Sea (the highest salinity generally
-- upto 20% of sea water)
has an extremely high noise content (witness the low R2's < 10%).
Since 1920 the central Black Sea salinity has decreased at a rate of
around .7 points/C --
from around 18.2% in 1920 to around 17.6% of seawater in c2000. Only
some of the tests I've run
show > 90% significance for this trend.
Since 1920 the central Black Sea temperature has also decreased at a
rate of around 3C per
century. All tests for this trend show > 90% confidence (the serial-
corr adjusted procedure
gets a confidence of 98.5%).
With both the water temp and salinity showing a trend decrease, it
seems reasonable to expect
"sea ice" formation in the Black Sea to have increased over time,
given winter water temps are
near freezing and perhaps only the 15-20% salinity of the "sea" water
was preventing it from
freezing in the normal course of events.
