First Large-Scale Autonomous Acoustic Survey

Fish stock assessments along the West Coast provide an essential view into fish populations and are integral to setting fishing rules and limits for the commercial fishing industry. In the summer and fall of 2018, five saildrones set off in a partnership with NOAA to improve the efficiency and accuracy of the West Coast assessment. This was the first integrated USV and ship survey of the North American West Coast.

The goal of the mission was to augment ship-based fish stock assessments and answer questions about whether autonomous data collection can improve the effectiveness and efficiency of fisheries management on the West Coast. Using echo sounder sensors, the USVs collected a data set on the fish stock of hake, sardine, and anchovy populations. Throughout the mission, the USVs duplicated the path of the NOAA Fisheries ship Reuben Lasker in addition to collecting data closer to shore, beyond where NOAA ships can safely navigate.

2018 Baja California Mission

In the summer of 2018, a Saildrone unmanned surface vehicle (USV) was launched in San Francisco to follow a course south along the US/Mexico coast toward Guadalupe Island. A coalition of 23 scientists involved in 17 projects tracked the saildrone across the highly variable California Current System with two main areas of focus: To assess the utility of Saildrone measurements for satellite sea surface temperature (SST) validation and model assimilation; and to study air-sea heat flux along dynamic frontal regions using Saildrone’s core payload of sensors and an Acoustic Doppler Current Profiler (ADCP).

White Shark Cafe Ecosystem Survey

The white shark is among the most iconic predators in the ocean, but for all their public exposure, the lives of white sharks remain shrouded in mystery. In 2018, two saildrones tracked tagged white sharks with the goal of shedding some light on a long-standing question around their migratory habits. Why do white sharks regularly congregate in a seemingly inhospitable part of the ocean?
