Our route was from Pt Loma to the Nine Mile Bank near the Mexican Border, we then turned northwest and ran the length of the bank to the 178 spot (3 n.miles northwest of the bank), then straight west across the San Diego Trough to the 182 spot on the inside edge of the 30 Mile Bank then north. We left the dock around 1230, checked the bait docks, and cruised by Ballast Point (no Oystercatchers seen). We remained in S.D. Co. waters for all but part of the last hour of daylight (L.A.Co.). As noted before, the Wilson’s Storm Petrel was the best bird in S.D.waters, but a imm. Long-tailed Jaeger, is always a good S.D. bird, and was closer than expected , at about 16-17 n.mile ( S.D.Trough). Leach’s Strom Petrels (chapman’s) were also a bit closer ( S.D.Trough and 30 MIle Bank). Least Storm Petrels were seen near the far edge of the S.D. Trough, at about 20 n. miles.
This is a partial count of species of interest. Todd Mc Grath, and Jon Feenstra will release the complete counts (which will be higher), with trip totals.

A bit of a surprising miss in S.D. waters was Ashy Storm Petrel. That species has been present in small numbers (2-15) all summer. We also found them absent or in very small numbers in the traditional areas around the outer Channel Is. (S.Rosa Is.-S. Miguel Is, and Point Conception.).
Black Storm Petrel remain in low numbers and scattered . That species has been a puzzle to me this year. I’m used to seeing large rafts on the 30 Mile Bank ( sometimes even on the Nine) numbering in the thousands. We have not found that this year.
Though we did not see Red-b Tropicbird in S. D. waters the number (20+) off the escarpment is nothing less than amazing . Seen on the 5th (3) and 6th (18) of Sept. along the escarpment.
Red Phalarope numbers well offshore were high (700+),with scattered Reds throughout the trip, made it the most abundant species seen.
Arctic Tern seems all but absent (2-3 seen) for the second straight trip…?
S.P. Skua numbers (7-8) were impressive on this trip, though missed in S.D. Co.
and last a seeming out of place a White-tailed Kite at sea between Santa Barbara Is. and San Nicholas Is. I gather they are regular winter visitors to the Channel Is. so I guess it’s not so strange that one would be out here. I have to admit that seeing a W-t kite coming up the wake, into the gull flock does make one do double and triple takes.
The marine mammal show off Southern California remains exceptional. Blue and fin whales, Common (both Long and Short beaked), Risso’s, and Bottlenose Dolphin were all seen in S.D. waters, with Humpback, Baird’s Beaked, Cuvier’s Beaked, and a un- I.D. possible Mesoplodon sp. whales. Also Pacific White Sided Dolphin all seen elsewhere on the trip. We also saw both Northern and Guadalupe Fur Seals, along with the usual Harbor Seal, and Calif. Sea lions.
Sea surface temps were warm off San Diego 70-73 (highest on the 30 Mile Bank), and cooler further out 59-61 degrees off Point Conception, 62-63 inside the San Juan Seamount. 64-68 down toward the Bell Bank(southern limit of the trip).
Winds were mostly 10 kts or less, except San Miguel Is. to Point Conception, and west, on Wed., with gust to 20 kts. The southern end of the trip, Thursday 9-05-12 , along the escarpment had winds 5kts or less. Partly cloudy to clear, except some fog, and heavy overcast south of Santa Rosa Is.
My thanks to Art Taylor and Celia Condit owners and operators of Searcher Natural History Tours for another quality trip offshore. Thanks to Capt. Aaron Remy, and crew for getting us to some rarely visited location, put us in position for the best views, keeping us well fed, and returned safely home. Thanks also to all passengers for exceptional company at sea.
