2. with the nominal track breakdowns and tables. Cursory non-grid observations taken south of the San Francisco Bay area on the 22nd are discussed here but have not been entered on ADP forms. Excellent cooperation was received from Captain Kaiser, the deck force, weather and B-T personnel, and all concerned with the operation of the Granville Hall. Conditions: Weather and sea surface conditions were, in general, quite variable during the cruise. Over the first non-grid leg winds were low to moderate from the north and northwest, with partly cloudy skies and occasional squall areas. The northern third of the grid area was very good for obser- vations with light north or northwest winds, partly cloudy to obscured sky and calm or light seas. Occasional patches of low fog on the morning of the 14th is a phenomenon not previously noted (since at least EGS #6). High winds and broken skies on the 15th gave way to clear and calm on the 16th. Moderately poor conditions on the 17th, 18th, and 19th calmed to fairer weather for the last three days. Patches of heavy fog and calm seas were present out of San Francisco on the 22nd. "Slick" areas were found on the 12th, 13th and 16th. Many logs and floating debris were seen on the 16th. No Velella were seen; kelp was not much in evidence. A near full moon and clear skies made for poor nocturnal observing conditions. The data totals, tables, and statistics for this cruise differ from previous surveys in that Black-footed Albatross observations are excluded. Albatross data are discussed only in the Species Account section. Eastern Grid Survey # 13 Over 993 miles and 108.4 hours of diurnal observations, 518 birds of 27 species were recorded. Twenty-five birds of at least two species were recorded over 79 miles of nocturnal watch. Fifteen specimens of five species were taken (see Summary Tables 1-4). Salient Highlights 1) High numbers of Sooty Shearwaters moving diagonally south- west across the grid.
