The shearwaters were attracted to the skiff and were quite easy to collect. The ship itself would make them veer away long before they were within shooting range. We tried chumming with squid from the fantail of the ship to attract albatrosses, shearwaters and petrels. We were successful and collected four banded albatrosses in this manner. Had we put the skiff over at this time we could have taken shearwaters and a few petrels. Spotlights were used at night to attract birds but only one petrel was taken. One Pterodroma (not P. inexpectata) was attracted to the light but we were unable to collect it. Oceanographic Work We can only generalize on the correlation of the oceanographic data with the distribution of birds at-sea at this time. When Mr. Ingraham's report comes out we may be able to make specific statements. The ship made several Nansen Bottle casts to 1,000 meters and at least three bathythermograph readings to 260 meters each day, sometimes several more. It appeared at the time that the distribution of birds in the area covered was governed by the salinity, surface and sub-surface temperature of the water. Marine Mammals Several species of mammals were observed on the cruise and all observations are listed in Table 2.
