FOR A DROP OF CLEAR WATER THE IONIAN SEATHE IONIAN SEAThe Ionian sea(from Greek Inion Plagos) is the part of the Mediterranean sea which stands between the Eastern Italian coasts of Apulia, Basilicata , Calabria, Eastern Sicily to the West and Albania and Western Greece to the East.It stands from the Otranto canal in the North, while its Souther limit is uncertain because it becomes blue water or open sea.It is the deepest part of the Mediterranean sea: 4000m in a lot of parts and over 5000 , Calypso Deep, in South-West part. Ther are a very few islands in the Italian part, while a lot of quite big islands are in the Greek part and they are called Ionian islands, such as Corfu, Zakynthos, Kephalonia, Ithaca Kephalonia.

OUR SEA SAMPLE TAKING On April 7 th Luca took the sea sample

OUR ANALYS IN OUR LABOn April 8 th we started our analysis

OUR SET FOR SEA WATER ANALYSIS

First of all we measure the sea water temperature :18 C

Then we teste the water hardness using French degrees: 15, quite hard.

The PH acidity of the water is :7,6

So the total hardness is between 9-11, an average value

Next we test the Magnesiun and the Calcium together: 1700 mg/l

Than we measure the quantity of Calcium: 25g/500mg and so we calculate the value of magnesium: 1200mg/l , which are good values!

Now we test Ammonium: < 0.05 mg/l which is below the average value of
