Adriatic Sea hydrology. Boll. OceanoL teor. app/., II(2):169-194. (In Italian, English abstract.)

An overview of Adriatic Sea hydrology is presented. Portions of the report cover sea level oscillations. Also discussed are salt budget calculations at Otranto which explain the fundamental features of the Adriatic Sea hydrology; improved water budget computations that yield an annual average flow rate in the Channel of Otranto of ~100,000 m3/s; and a description of local circulation characteristics.

Maximum sea surface temperatures were observed between latitudes 6-10°S; a sharp fall of temper- ature was found near the convergence zones (lati- tudes 40-50°S). Surface temperatures ranged 28.7°C to 1.7°C. The depths of the isothermal (mixed) layer in Antarctic waters south of latitude 68°S extended to 200--400 m while elsewhere they were < 100 m. A

convergence process was taking place around 60°S with Antarctic surface water slipping below and mixing with the subantarctic surface water. T-S analysis shows changes in T-S relations of Antarctic intermediate water as the distance from the Antarc- tic convergence increases. Natl. Inst. of Oceanogr., Dona Paula, Goa 403 004, India.

Effects of the 1982-83 El Nifio revealed by satellite infrared temperature data include anomalously warm sea surface temperatures, especially near the coast, and weakened coastal upwelling which pre- sumably contributed to the reduced primary pro- ductivity recorded by the CZCS.
