Welcome to Scuba-Eco
Today the variation in environmental challenges is enormous. The aquatic realm is affected by many. Coverage in the press is dominated by climate change, food production and sea level rise – they are considered to have the biggest effect on human populations. These are not the only challenges for the (near) future. In one of the biggest eco system assessments ever done by the UN, the millennium assessment has identified inland and coastal waters to be among the ecosystems most affected by human activities.
Scuba divers are witness of changes in the underwater world. Their first hand reports can help to assure early recognition of deteriorating ecosystems. Scuba-eco is a web service for (and by) scuba divers to assist them to perform their adopted role as ambassadors for the aquatic realm.
Some changes in underwater ecosystems are easy to recognize. Coral bleaching is an example of a major, but readily visible change. Other problems can go largely unnoticed, until it is too late. This web page is dedicated to such a problem – nutrient loading (eutrophication) of inland and coastal waters.
The consequences of nutrient loading can be enormous, ranging from destruction of coral reefs to the development of zero-oxygen zones in which all bottom life will die. A problem is that nutrient levels in the water are not visible for divers until it is too late. To inform you on the details of the nutrient problem, you can print an information brochure.
The nutrient loading program is designed to train divers in measurement of nutrient levels and to provide them with a platform to share their data with others around the world. Active involvement increases the understanding of the problem. Via the webpage, divers can find (and contact) locations with similar conditions, but other nutrient levels to find out what can be done to change the local situation. With the awareness gained by participation in this program, divers can become true ambassadors for the local underwater realm and inform the local population and authorities on possible actions.
This webpage gives full access to all data collected by divers around the world and assists in comparing the local situation with other locations. Dive centers adopt one or more dive sites and measure nutrient content on a regular basis. If you want to get involved, go to the Dive Centers page and select an operation close to you. Instructors can do an online qualification program to set up a project in their region (always in cooperation with a Dive Center – registration can be done here).
Scientists wanting access to the collected data can contact the webmaster for an Excel compatible file.
