“…Both Wave Glider and Saildrone have successfully collected pH and pCO 2 data simultaneously [28,29]. However, given its long umbilical, the Wave Glider would require more than 7 m of water depth [26] and the Saildrone has a 2.5 m keel [29], which would render both unsuitable for a significant portion of our study area, and in many shallow coastal regions home to ecosystems such as coral reefs and seagrass.…”

The interface between land and sea is a key environment for biogeochemical carbon cycling, yet these dynamic environments are traditionally under sampled. Logistical limitations have historically precluded a comprehensive understanding of coastal zone processes, including ocean acidification. Using sensors on autonomous platforms is a promising approach to enhance data collection in these environments. Here, we evaluate the use of an autonomous surface vehicle (ASV), the C-Worker 4 (CW4), equipped with pH and pCO2 sensors and with the capacity to mount additional sensors for up to 10 other parameters, for the collection of high-resolution data in shallow coastal environments. We deployed the CW4 on two occasions in Belizean coastal waters for 2.5 and 4 days, demonstrating its capability for high-resolution spatial mapping of surface coastal biogeochemistry. This enabled the characterisation of small-scale variability and the identification of sources of low pH/high pCO2 waters as well as identifying potential controls on coastal pH. We demonstrated the capabilities of the CW4 in both pre-planned “autonomous” mission mode and remote “manually” operated mode. After documenting platform behaviour, we provide recommendations for further usage, such as the ideal mode of operation for better quality pH data, e.g., using constant speed. The CW4 has a high power supply capacity, which permits the deployment of multiple sensors sampling concurrently, a shallow draught, and is highly controllable and manoeuvrable. This makes it a highly suitable tool for observing and characterising the carbonate system alongside identifying potential drivers and controls in shallow coastal regions.

“…in the Gulf of Mexico (Wall et al, 2012(Wall et al, , 2013(Wall et al, , 2014 as well as various species of whales in the Gulf of Maine (Baumgartner et al, 2013). Similar to other autonomous vehicles, the Wave Glider (Hine et al, 2009) is a mobile platform that can be equipped with environmental sensors for measuring temperature, salinity, fluorescence, as well as acoustic doppler current profilers (ADCP), acoustic transponders and GPS motion sensors (e.g., Kraus and Bingham, 2011;Mullison et al, 2011;Bingham et al, 2012). It is unique in that it can harness ocean wave energy for forward platform propulsion, allowing for extended mission durations without the requirement for diving to depth, as is needed for buoyancy gliders.…”

Mapping Fish Chorus Distributions in Southern California Using an Autonomous Wave Glider

Passive acoustics is a tool to monitor behavior, distributions, and biomass of marine invertebrates, fish, and mammals. Typically, fixed passive acoustic monitoring platforms are deployed, using a priori knowledge of the location of the target vocal species. Here, we demonstrate the ability to conduct coastal surveys of fish choruses, spatially mapping their distributions with an autonomous surface vehicle. For this study, we used an autonomous Liquid Robotics Wave Glider SV3 equipped with a Remora-ST underwater acoustic recorder and hydrophone. The exploratory 15-day deployment transited through three marine reserves, resulting in approx. 200 h of passive acoustic recordings, and revealed five distinct fish choruses from La Jolla to Capistrano Beach, CA (approx. 80 km separation), each with unique acoustic signatures. Choruses occurred in the evening hours, typically in the 40 to 1000 Hz band. There was a lack of both temporal and frequency partitioning amongst the choruses, but some choruses exhibited distinct spatial niches by latitude and water temperature. These results suggest that the mobility of the Wave Glider allows for persistent surveys and studies that otherwise may be too challenging or costly for stationary or shipbased sensors; a critical consideration for documenting biological activity over large spatiotemporal scales, or sampling of nearshore marine reserves.
