Shark Research Equipment Fundraiser

About the campaign

Every year between December and March pregnant Spotted Ragged-tooth Sharks migrate into the iSimangaliso Wetland Park - South Africa where they spend most of their nine month gestation period. The 3 year study aims to identify key congregation areas and movement patterns of the pregnant sharks. Understanding the sharks’ spatial and temporal abundance is key to protecting important congregation sites and migratory corridors.

 

We are raising funds for a Tilt Current Meter to measure the effects of current on the resting females. This is crucial to understanding their movement patterns.

 

The TCM-1 Tilt Current Meter measures current using the drag-tilt principle. The logger is buoyant and is anchored to the bottom via a short flexible tether. Moving water tilts the logger in the direction of flow. The TCM-1 contains a 3-axis accelerometer and 3-axis magnetometer for measuring tilt and bearing. The resulting orientation data is converted to current by applying calibration coefficients.
