Clod Cards, simple ocean current sensor for optimal reef barrier ecosystem health

  1. Technology: Clod Cards. A range of ocean sensors have been developed to gather information about ocean flows, ecosystem characteristic, and pollution, to name a few. While many of the sensors can be large and are made of expensive, resource heavy materials, like metal, and energy heavy manufacturing process, there is one sensor that is made of natural biodegradable material, plaster. Plaster is a densification of limestone using organic binders; this sensor is called a Clod Card. The plaster card wears away from the friction created by moving water creating data on the rate of water movement.
  2. Sustainable issue: This type of information is critical for both the survival of our oceans ecosystem but also the survival of land formations, including urban development. For example, storm surge strength as it meets land can be reduced by 90% with a healthy coral reef. Corals rely on the movement of water around their formations for food and oxygen. In other words, still waters will kill Coral.
  3. Technology stakeholders: Currently NOAA, The National Oceanic and Atmospheric Administration, are the key stakeholders. The potential to bring NOAA to the planning table for coastline cities, would create a sustainable development platform and would broaden the stakeholders of this technology to a cities Urban Planning dept. and its Disaster Risk Management program/dept.
  4. Process for implementation: A. Assign the responsibility of incorporating ocean and atmosphere data into the urban planning process to one of the Urban Planning deputies. B. Create a meeting between NOAA and the cities Urban Planning Dept. C. Create an internet connection between data from NOAA to the Urban Planning Dept. D. Bring a NOAA scientist onboard as a consultant to translate the information so that an Urban Planner can understand it and use it. E. Design appropriate edge conditions between the cities ocean and land formation to create optimal ocean current movement.
