TZCF Oceanographic Survey (SE1505)

Oceanographic data were collected along the 159W and Meridional from 26? 30'N-32? 30'N. CTD casts were conducted at predetermined stations. CTDs were equipped with oxygen sensors and fluorometers, and chlorophyll and nutrients were measured at discrete depths. Biological backscatter was monitored using the multifrequency EK60 echosounder system operating at 38, 70, 120, & 200 kHz.

Data Update Frequency Not planned
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.
