On the next line of stations in 25° S. another such eddy can be defined, but here the oceanic water appeared to extend right in to the coast, causing the cooler water from the south to be displaced seawards. The increase to oceanic temperatures was not evident until WS 986, the westernmost station on the line. It may be that local heating of the surface-waters in the vicinity of station WS 988 had complicated the picture here, but the salinity at WS 988 was higher by 0-06 %0 than at the next station seaward, not only at the surface but throughout the water column. A difference in salinity of this order of magnitude may not be significant in itself, but in conjunction with the temperature data
