Coral Reef Survey
Pacific Whale Foundation (PWF) was recently contacted by WHALE Environmental Services LLC and asked if we were interested in a collaboration, as this Oahu-based company was planning to undertake a pilot project to survey the West Maui coral reefs. PWF was very keen to take part, and so we made arrangements to take our research vessel, Ocean Protector, out as a diving vessel for a change.
Using a standardized method, we made very short dives at 14 coral reefs along the coast of West Maui, between Ma’alaea Harbor and Honolua Bay. While scuba diving, we took note of various factors which would be used to indicate reef health, such as:
- the number of coral species observed
- the number of fish species observed
- signs of pollution
- signs of erosion
- signs of coral disease or bleaching
- signs of fishing pressure
- signs of stormwater entry at the site
It was interesting to see the stark differences between a healthy reef and an unhealthy reef. This project is a baseline study – meaning that we are recording the current state of these reefs so we have a measurable starting point and can monitor the reef and detect any changes in the future. In science it is very important to record a baseline so you know when changes are happening. You then have data on how fast or slow changes are occurring, or in what locations.
While we await the results of the report that is being prepared, the research department is back to its usual summer routine of carrying out transect surveys for dolphins and marine debris.
