Saltier sea Oceanographers have documented the growing saltiness of the Atlantic in the tropics, in opposition to freshening of the polar oceans. The changes in the sea-surface salinity indicate changes in the hydrologic cycle, the researchers say, which may be attributable to human-induced climate changes. |
