An interdisciplinary study of the Kuroshio nutrient stream 

The surface water of the Kuroshio, a western boundary current in the North Pacific Ocean, is nutrient-depleted and has relatively low primary productivity, yet abundant fish populations are supported in the region. This is called the “Kuroshio Paradox”. 

Kuroshio Current: Physical, Biogeochemical and Ecosystem Dynamics presents research from a multidisciplinary team that conducted observational and modeling studies to investigate this contradiction. This timely and important contribution to the ocean sciences literature provides a comprehensive analysis of the Kuroshio. 

Volume highlights include: 

  • New insights into the role of the Kuroshio as a nutrient stream
  • The first interdisciplinary examination of the Kuroshio Paradox
  • Reflections on the influence of the Kuroshio on Japanese culture
  • Research results on both the lower and higher trophic levels in the Kuroshio ecosystem
  • Comparisons of nutrient dynamics in the Kuroshio and Gulf Stream
  • Predictions of ecosystem responses to future climate variability
