Wind pattern change along a period of coastal occurrence variation of a stinging medusa on a SW Atlantic beach
Summary
The study identifies a significant decrease in wind speed and a reduction in coastal upwelling days at Monte Hermoso between 2008 and 2015, coinciding with the absence of the medusa Olindias sambaquiensis. It also notes a 0.4 °C increasing trend in sea surface temperatures over the eight-year period, suggesting these environmental changes contribute to the lower occurrence of the species.
Key insights
- A significant change in wind patterns was detected at Monte Hermoso from 2008 to 2015, characterized by a decrease in wind speed from 6.3 m s-1 to 2.4 m s-1, with calms increasing by over 44.2% and light winds increasing by 7.5%.
- The reduction in wind speed impeded coastal upwelling, the process that brings medusae to the coast; coastal upwelling-days dropped from 45 in summer 2008 to only 8 in summer 2015.
- Sea surface temperatures (SST) showed a positive anomaly over the eight-year period, indicating an increasing trend of 0.4 °C, which may negatively impact polyp reproduction during winters.
