Drifters
Deepwater drifters are typically called SVP drifters as they were developed by the Surface Velocity Program (SVP) of the Tropical Ocean Global Atmosphere (TOGA) experiment and the World Ocean Circulation Experiment. They consist of a surface float, a tether, and a drogue. The surface float contains a battery, instruments that collect data, and a transmitter that relays the position of the drifting buoy and data collected by the instruments to satellites. The tether connects the surface buoy to the subsurface drogue, which sits at about 15 meters below the ocean's surface.

Underwater hydrophones
One of the primary applications of hydrophones in studying ocean pollution is marine bioacoustics. Marine bioacoustics is the study of how marine organisms produce and are affected by sound. Sound travels faster and farther in water than in air, making it an effective means to explore and monitor underwater ecosystems. Hydrophones enable researchers to study the impact of human-generated underwater noise on marine life, including marine mammals, fish, and coral reefs. By deploying hydrophones, scientists can measure and analyse the acoustic signals present in the ocean, helping them understand how different species communicate and navigate their environment.
Additionally, hydrophones play a vital role in marine conservation efforts. They can be installed in marine protected areas to provide continuous, non-intrusive monitoring of acoustic environments. By tracking unique sound profiles, hydrophones help detect and locate human divers, enhancing security near critical infrastructure and protected marine habitats. This technology also assists in studying species distribution, migration patterns, and ecosystem health, which is essential for protecting endangered species and ensuring sustainable practices.
The accessibility and affordability of hydrophone technology have been improving, making it more widely available for research, education, and community science initiatives. The development of low-cost, open-source hydrophones has empowered scientists, educators, and community members in underserved regions to actively participate in ocean monitoring and conservation efforts. This democratisation of technology enhances global collaboration and contributes to a more comprehensive understanding of ocean health and the impact of human activities on marine environments.

Animal telemetry
One of the key advantages of animal telemetry is its ability to track and monitor animals over vast distances and in diverse environments, from coastal ecosystems to polar seas and open oceans. This is achieved through the use of satellite-linked biologgers and networks of acoustic receivers, which provide reliable data on animal movements and habitat usage. For example, satellite tags have been used to study the migration patterns of olive ridley turtles, leatherback turtles, and elephant seals, helping scientists understand how ocean pollution may impact their journeys between feeding and breeding grounds.
The data collected through animal telemetry can also provide valuable oceanographic information. Tags can record an individual's location, speed, dive depth, and the temperature and salinity of the surrounding water. This data can be used to map ocean profiles and provide insights into the physical environment, including essential ocean variables (EOVs). By using animals as autonomous sampling platforms, researchers can increase the spatial and temporal coverage of global oceanographic observation systems, improving our understanding of the oceans and the impacts of pollution.
Additionally, animal telemetry has advanced through technological innovations such as miniaturization, improved battery efficiency, enhanced memory capacity, and reduced unit costs. These advancements have made tags accessible for studying a wider range of species, from small salmon smolts to massive whales. The development of more sophisticated sensors has also provided unprecedented insights into the lives of marine animals, allowing researchers to study their behaviour and physiology in relation to their environment.
In conclusion, animal telemetry is a critical tool for studying ocean pollution and its effects on marine ecosystems. By collecting data on animal movements, behaviour, and the physical environment, scientists can gain valuable insights into the impacts of pollution and inform conservation and management strategies. The continued advancement of telemetry technology will further enhance our understanding of the complex relationships between marine life and their changing ocean habitats.

High-frequency radars
High-frequency (HF) radar systems are an important tool for studying ocean pollution. These systems measure the speed and direction of ocean surface currents in near real-time, providing critical data for understanding the movement of pollutants. HF radar data is used to track and forecast pollution plumes, inform search and rescue operations, and support maritime activities and water quality monitoring.
HF radar technology has been used to support maritime operations and water quality monitoring for over a decade. The U.S. High-Frequency Radar Network (HFRNet) has been in operation for over 13 years, with data ingested from 31 organizations, including measurements from Canada and Mexico. HFRNet currently holds millions of records of surface ocean velocity measurements from over 150 radar installations.
HF radar systems are particularly useful for studying ocean currents, which play a crucial role in the transport of pollutants. These currents are equivalent to winds in the atmosphere, carrying nutrients, pollutants, and any floating objects. By understanding the speed and direction of these currents, scientists can track the movement of pollution plumes and predict their impact on coastal areas. This information is vital for ecological and economic reasons, helping to protect both the environment and human activities that depend on healthy marine ecosystems.
HF radars can measure currents over a large region of the coastal ocean, from a few kilometers offshore up to about 200 km. They can operate under any weather conditions and do not require a high point of land for placement. The maximum range of HF radar signals depends on factors such as sea state, external interference, and radar transmit antenna. For example, a standard 12MHz signal might travel 90 km in the coastal ocean but only about 5 km over freshwater due to the conductivity difference between seawater and freshwater.
HF radar data has been used in a variety of applications, including marine safety, oil spill response, tsunami warning, pollution assessment, and coastal zone management. For instance, in the case of wastewater spills in San Francisco and Marin County, radar operators provided surface current tracking tools that helped emergency responders estimate the plume trajectory and direct cleanup efforts effectively. Additionally, the U.S. Coast Guard integrated HF radar data into its Search and Rescue system, aiding in the rescue of disabled vessels and stranded individuals.
