“…This is due to the influence of the southeast trade winds (SETWs) on the climate of the island. The resulting effect is a decreasing gradient in precipitation between the southeast and northwest, also observed by Fowdur et al (2014) and Staub et al (2014). This is especially seen on the central plateau which comprises the three inland precipitation regions (regions 2, 3 and 6) determined by the CA.…”

“…While some factors were considered statistically insignificant in the present study, they are still important when considering precipitation in Mauritius. Staub et al (2014) saw a positive relationship between slope and annual precipitation.

The aim of this study was to quantify the regional precipitation patterns of Mauritius using the total mean annual precipitation of 52 meteorological stations for the period 1981–2010. Principal component analysis was first used to determine the significant variables influencing precipitation in Mauritius. A cluster analysis was then applied to group the stations according to the significant variables identified. Finally, a spatial interpolation of precipitation in Mauritius using the kriging with external drift technique was carried out to examine the spatial distribution of precipitation on the island. The principal component analysis results showed that elevation and coastal proximity caused the most variance in the dataset with respect to precipitation. Using the cluster analysis and kriging results, six regions of precipitation were determined: three inland and three coastal regions. A decreasing gradient in precipitation between the southeast and northwest is observed due to the southeast trade winds and the altitudinal difference between the coastal areas and the central plateau. The central plateau represents a distinct precipitation zone which receives the highest precipitation on the island. The windward‐facing south and eastern highlands experience orographic precipitation as a result of adiabatic air expansion and therefore are more humid. On the other hand, the northeast highlands region, together with the north and western coasts which lie in the leeward rain shadow, are notably drier.

“…A more extensive spatial analysis was done on the rainfall data using ArcView GIS. Simulated monthly rainfall totals generated by Staub et al 2014 were averaged across months and then by watershed for each study year. In their study, monthly rainfall totals (2000-2011) from 85 stations, a digital elevation model (DEM) and location-specific landscape characteristics were used to calculate linear relationships between mean rainfall and landscape characteristics on Mauritius.…”

Coral reefs are degrading through the impacts of multiple anthropogenic stressors. How are coral reef communities going to change and how to protect them for future generations are important conservation questions. Using coral reef data from Mauritius, we examined changes in cover in 23 benthic groups for a 13-yr period and at 15 sites. Moreover, we determined which land-based stressor out of four (human population, agriculture, tourism, rainfall) correlated the most with the observed changes in coral reef cover. Among the stony corals, Acropora corals appeared to be the most impacted, decreasing in cover at many sites. However, the non-Acropora encrusting group increased in cover at several sites. The increase in abundance of dead corals and rubble at some sites also supported the observations of stony coral decline during the study period. Additionally, the decline in stony corals appeared to be more important in second half of the study period for all sites suggesting that a global factor rather than a local factor was responsible for this decline. There was little change in cover for the other benthic groups, some of which were quite rare. Human population was significantly correlated with changes in coral reef cover for 11 sites, followed by tourism and agriculture. Rainfall, a proxy for runoff, did not appear to affect coral reef cover. Overall, our results showed that there has been a decline of stony coral especially the ones with complex morphologies, which in turn suggest that coral reefs around Mauritius have experienced a decline in habitat complexity during the study period. Our study also suggests that humans are an important factor contributing to the demise of coral reefs around the island.

The atmospheric corrosion performance of S235 carbon steel is assessed when exposed to the tropical/marine aerosol pollutants of Port Louis, Mauritius. Port Louis is situated on the northwest coast and has a distinct microclimate, leading to major atmospheric corrosion concerns. In addition, sulphur dioxide emissions from three heavy oil‐fired power stations complicate corrosion prediction within the region. Mass‐loss analysis shows distinctive corrosion progression behaviours linked to the environmental and geographical variables. The formation of porous surface layers leads to a continuous increase in metal dissolution during the electrochemical process. The surface analysis reveals lepidocrocite false( γ ‐ FeOOH false) $\left(\gamma \mbox{-} \text{FeOOH}\right)$ and goethite ( α ‐ FeOOH $\gamma \mbox{-} \text{FeOOH}$) as the predominant rust phases, with low percentages of magnetite ( Fe 3 O 4 ${\text{Fe}}_{3}{{\rm{O}}}_{4}$), akageneite false( β ‐ FeOOH false) $\left(\beta \mbox{-} \text{FeOOH}\right)$ and jarosite ( normalK Fe 3 ( OH ) 6 ( SO 4 ) 2 ) $({\rm{K}}{\text{Fe}}_{3}{(\text{OH})}_{6}{({\text{SO}}_{4})}_{2})$. A key insight in the S235 atmospheric corrosion involves two stages: the early rapid corrosion stage followed by a slow stage of linear or power‐law corrosion kinetics due to the formation of stable rust phases.
