Increasingly, oceanographic data is collected in situ, using sensors on autonomous platforms such as moorings, floats and gliders. Biofouling presents a major challenge to the ability of scientists to acquire accurate and stable data over long deployments. We will develop and test a system based on the proven anti-fouling ability of ultraviolet light. A prototype unit will be constructed for use with an Aanderaa Instruments dissolved oxygen optode which we will deploy at the Martha’s Vineyard Coastal Observatory. Performance of the optode with antifouling system will be compared to a control optode. In the future, our results should be readily adaptable to a wide range of oceanographic sensors and platforms, including floats and gliders, leading to improved capabilities for ocean observing science missions, particularly in coastal, highly productive and remote regions of the ocean.
