Abstract/Contents

Abstract: Palmyra Atoll is located at 5.9° N, 162.1° W in the Line Island chain. It is in the southern region of the North-East Trade winds, and in the midst of the North Equatorial Countercurrent (NECC) year round. ADCP, fluorometer, and CTD data was used to sample the water column to depths of 300 meters during a cruise aboard the Robert C. Seamans in May and June 2003. A southeasterly incident current generated significant shear and mixing as it passed the island. The wake of the island showed enhanced primary production as indicated by a raise in chlorophyll a concentration. The greatest enhancement seen was near a cold-core cyclonic eddy to the south. Areas of elevation in the thermocline showed corresponding enhancements in productivity, suggesting that upwelling deep water is an important source of nutrients to Palmyra’s ecosystem.
