Consider the following statements about the Sargasso Sea : 1. It is the only sea without a land boundary. 2. The Sargasso Sea records the lowest salinity in the Atlantic Ocean. Which of the statements given above is/are correct ?

The Sargasso Sea, located in the North Atlantic Ocean, is unique as it has no land boundaries — it is bounded entirely by ocean currents (the Gulf Stream, North Atlantic Current, Canary Current and North Atlantic Equatorial Current) — so statement 1 is correct. However, due to high evaporation and limited inflow of fresh water, the Sargasso Sea actually has HIGH salinity (among the highest in the Atlantic), not the lowest. Hence statement 2 is incorrect. Therefore only statement 1 is correct.
