sharklife field station
Driving conservation impact by lowering barriers to marine research
The Station’s Vision
The Sharklife Marine Research Field Station exists to accelerate conservation-driven marine science in the iSimangaliso Marine Protected Area by breaking down logistical and financial barriers. By supporting Principal Investigators through infrastructure, local expertise, and collaborative partnerships, the Station aims to make high-impact research both feasible and effective. Through this model, Sharklife fosters a future where marine science informs protection, and Marine Protected Areas become platforms for innovation and conservation leadership.
Focal Research Platforms

Sharks and Rays
The Sharks & Rays Platform is vital for elasmobranch conservation, especially given the threatened status of many shark and ray species. This platform uses specialized monitoring techniques, including telemetry, to track shark movements and Stereo-BRUVs to detect temporal trends in species populations and community structures. It also incorporates habitat classification and environmental data to better understand the conditions impacting these species. These combined tools provide essential insights into population dynamics, habitat use, and environmental stressors, all critical for the effective conservation and management of these vulnerable species.

Reef Ecosystems
The Reef Ecosystems Platform is dedicated to assessing coral reef health, a key factor in maintaining marine biodiversity but highly sensitive to changes in water quality, including variations in pH, nutrient levels, and biodiversity loss. Regular evaluations are conducted using Stereo-BRUVs for habitat classification, water sampling, long-term underwater temperature recorders, and Passive Acoustic Monitoring to capture reef soundscapes. These methods offer critical insights into the status of reef ecosystems, their biological activity, and the broader environmental conditions influencing their health.

Coastal Ecosystems
The Coastal Ecosystems Platform monitors atmospheric conditions such as temperature, CO2 levels, and UV index, all of which can directly or indirectly impact marine life. This platform also focuses on intertidal zone assessments, using AI for data analysis alongside long-term temperature loggers to track environmental changes over time. Additionally, it monitors marine turtle populations through Remote Underwater Video Stations (RUVS) and on-water observations, collecting valuable data on turtle behaviour and habitat use. Together with weather station data, these tools provide a comprehensive understanding of coastal ecosystem health and the impacts of climate change.
our primary RESEARCH methods

Stereo-baited remote underwater video systems
Stereo-baited remote underwater video systems (Stereo-BRUVs) are invaluable tools for conducting marine research, providing high-resolution data on species abundance, distribution, behaviour, and biomass.
To ensure representative sampling, a stratified random sampling approach is utilised, dividing the MPA into strata based on habitat types, depth ranges, and management zones. This method enhances the robustness and reliability of the data collected, ensuring thorough and scientifically sound monitoring efforts.

Remote Underwater Video Systems
The RUVS (Remote Underwater Video Systems) use GoPro cameras to capture images every 30 seconds for 10 days, providing a standardized view of aggregation sites and collects abundance data on spotted ragged-toothed sharks.
MaxN, the maximum number of sharks in a single frame, is recorded to estimate shark abundance. The I3S system analyzes spot patterns from the photo images to identify individual sharks, aiding long-term monitoring of the species.

Passive Acoustic Monitoring Systems
Passive Acoustic Monitoring Systems (PAMS) capture a broad spectrum of localised underwater sounds through the device’s omnidirectional hydrophone.
By analysing the soundscape data, patterns in shark movements, the presence of other marine species, and the level of anthropogenic noise can be assessed at shark aggregations.

Acoustic
Telemetry
The Vemco VR2W acoustic receivers are utilized in an array for monitoring ragged-tooth sharks and to detect tags from sharks that have been tagged outside of the park, providing
valuable data on shark migration patterns.
Data from each receiver is stored in a 2MB capacity and can be offloaded via VUE software. This array method provides a comprehensive view of shark distribution and movements within the park and its northern and southern boundaries..

Underwater
Visual Census
Underwater visual census (UVC) methods are used to gather data on turtles, spotted ragged-toothed sharks and manta rays. This non-invasive approach allows for direct observation of animals in their natural environment.
a Diver Operated Video Stereo System (Stereo-DOVS) is also used by a freediver to measure the fork lengths of the sharks, providing data on their size distribution.

Intertidal
Zone surveys
Intertidal Zone Surveys. A systematic approach to long-term monitoring of the intertidal zone will be implemented at selected sites within the Marine Protected Area (MPA), utilizing standardized photo-quadrat sampling in intertidal zone surveys.
This method involves the capture of georeferenced photographs of marked quadrats over a period of time, allowing for the analysis of biodiversity trends and changes in species abundance and zonation patterns.
