Ambitious marine monitoring bags 100 surveys
This past week the Nature Seychelles staff of Cousin Island were hard at work completing an ambitious marine monitoring project. We began the week by acknowledging that the plan we set out would take a solid team effort to achieve. Everyone based on Cousin was involved, providing boat skipping, diving, and support, as well as the Reef Rescuer team based on Praslin, who supplied necessary equipment. The team entered this week of bi-annual reef monitoring with excitement to get underwater and determination to complete the data collection in the allocated period. It proved to be a successful week as five divers jumped right into the work with enthusiasm. The island’s science officer along with two marine research assistants and two of the Cousin Island wardens completed over 100 surveys at three different sites around Cousin island in just six dives!
The survey sites were distributed around the island, and selected to provide a sampling of various benthic composition. As such, the different locations made for quite a variety of diving conditions. Some (read, a few) dives were calm and lovely with clear waters, sunshine filtering in, and schools of friendly Parrotfish flitting about. Others (read, most) resembled what I imagine it would be like to dive in the spin cycle of a washing machine, whirling and churning and sending Parrotfish flying. However, the divers persevered, executing their work with an excitement that was matched only by the size of the swell, rocking and rolling beneath their lovely dive boat.
The surveys completed throughout the week will allow the research team to compile a comprehensive report, detailing the density and diversity of target fish and invertebrate species as well as coral coverage of both adult and juvenile stages. This report can be used in comparison to a similar, more detailed report in the 2009. The results will hopefully demonstrate an improvement in the health of the marine life found in the 400-metre special reserve zone surrounding Cousin Island, which were heavily damaged in the 1998 el Nino bleaching event. As the researchers continue to write the report, they may head back into the water to collect additional data as necessary, however this past week was a great success and a wonderful show of teamwork as the staff succeeded in their ambitious fieldwork goals
