May 26th, 2003; Leg 7, Day #4

We continue to work our way northward along the coast of Baja California. Seasonal northwesterly winds of 25-30 knots do not impede our progress, although they prevented any diving operations today. Hydrographic stations at 28 N and 29 N were completed. The station at 28 N was located about 20 miles to the west of Cedros Island, and we encountered a westward current of about 1 knot. The iron profile for this station is shown below and shows a maximum iron concentration at about 150 m of 10 nM. This was about 510 times greater than peak concentrations at stations to the south. Perhaps the offshore (westward) current transported shelf waters, which were rich in iron, to this location.
