APPLICATION OF TOPEX/POSEIDON SATELLITE ALTIMETRY TO DESCRIBE LARVAL TRANSPORT IN THE HAWAIIAN ARCHIPELAGO WITH APPLICATION TO MARINE RESERVES AND FISHERIES MANAGEMENT
 
Advection-diffusion modeling was used to investigate larval transport of spiny lobster and deepwater bottomfish in the Hawaiian archipelago. Movement models were driven by monthly one-degree resolution geostrophic current fields computed from TOPEX/Poseidon satellite altimetry. The spiny lobster analysis concluded that there were strong spatial patterns in recruitment despite a protracted 12-month larval duration. These predictions corresponded well to the observed recruitment pattern from research surveys. Bottomfish models were used to investigate the magnitude of larval mixing between adjacent management regions. Reverse movement models were also configured to backtrack the source of successful recruitment. These tools have assisted in our understanding of recruitment dynamics, and have contributed towards an improved fisheries management for these species.
