In the paper entitled "Lagrangian measurement of subsurface poleward flow between 38 ø N and 43 ø N along the west coast of the United States during summer, 1993" by C. Collins et al. (Geophys. Res. Lett., 23(18), 2461-2464, 1996) the sentence in the abstract referring to the float speed should have read: The mean speed along this 500 • path was 16.3 cms-1. In the Results section, third paragraph, the last sentence should have read: The largest speeds, 25 to 35 cms-1, occurred during offshore movement north of St. Georges Reef, while along the coast speeds greater than 20 cms-1 occurred just to the north of Pt. Reyes, just south of Cape Mendocino, and about halfway between Pt. •'ena and Cape Mendocino.

A linear Wiener (least squares optimal) filter is used to predict the path of the Gulf Stream in the region between Cape Hatteras and 70øW using upstream ("Inlet") conditions as filter inputs. Although position, angle, curvature, geostrophic velocity, and curvature vorticity (nv) measured at 73øW were tested as multiple Inlet parameters, it was found that Inlet position alone was the best predictor. With Inlet position as the predictor, this filter is equivalent to propagating meanders downstream with a typical phase speed and growth rate. Forecasts of the downstream path position are produced, more accurate than persistence, 12 days in advance at 140 km from the Inlet, 24 days in advance at 240 km from the Inlet, and 28 days in advance at 340 km from the Inlet.
