Oceanography. Observations in the Medi- terranean. Observations in Spanish Bay. 292 DEPTHS OF THE OCEAN Gibraltar, the "Michael Sars " entered the Mediterranean, and took observations at Station 19, the hydrographical conditions being shown in Fig. 197. The surface temperature varied from 16° to 17° C, and the salinity was nearly per thousand. The temperature decreased and the salinity increased downwards, until we struck the Mediterranean deep water at a depth of about 160 metres ; from this point downwards we found exactly the same temperatures and salinities as in the undercurrent in the straits. This was on the 2nd May, between 10 and 1 ; the observations in the uppermost 300 metres were made between and Judging from the previous measurements the in- flow in the straits should then be about its strongest. Be- tween 5 and 6 some of the observa- tions were repeated, and the boundary be- tween the surface- layers and the deep water then lay some- what higher; it might be a matter of 10 or 15 metres. The under current setting out of the straits was then very strong and the surface current comparatively feeble. So there were fiuctua- in the Mediterranean the fluctuations in the.

A few days later a number of observations were taken in the Spanish Bay westward of the straits. The positions of the stations are indicated in Fig. 198, and the s
