Summary
Abstract: Data were collected along the 158?W and 161?W Meridionals from 22?30?N-36?00?N and from 31?15?N-35?15?N. CTD cats were conducted at predetermined stations. CTDs were equipped with oxygen sensors and fluorometers, and chlorophyll and nutrients were measured at discrete depths. Biological backscatter and currents were monitored using the EK60 echosounder system (38, 70, & 120 kHz) and an RD Instruments ADCP along the transects.

Purpose: The scientific objectives of this cruise are to collect data on physical and biological properties of major fronts within the North Pacific Subtropical Frontal Zone, where cooler, more productive subarctic water meets and sinks under warmer, less productive, subtropical water. This highly dynamic region influences the distribution of top predators? (such as tuna, swardfish) and turtles, resulting in changes in CPUE of fish and rates of fisheries interactions with turtles.
