Note The Parc naturel marin de Mayotte started monitoring the water temperature in 2015 at 13 different stations. After several probes were stolen, the number of stations was narrowed down to 9 stations. Nowadays, the probes are still active, regularly changed and the data are downloaded every two months ever since.

Abstract

Since 2015, 12 representative sites of the Mahoran reefs have been equipped on the sub-surface with probes measuring the temperature every 10 minutes (every 1 hour since mid-2021). The data from these probes are collected every 2 months by the Operations Department of the Parc marin de Mayotte. The aim is to better understand seasonal variations and bleaching phenomena. A computer program developed by the PNMM makes it possible to analyse these data. Regularly, new probes are purchased (NKE) and calibration tests are carried out.
