Symbiont counts

Lauren completed 10 symbiont counts for TP3. This data can be found in the Heatwave Google Drive. She also cleaned tanks with Danielle and fed the feeding experiment corals for 30 minutes starting at 17:30.

Heatwave

Danielle started the ninth day of the heatwave period for the corals to to experience a diel fluctuation in the heated treatement of 29.5 °C to 30.2 °C.

Daily measurements

Danielle recorded bleaching score and survivorship for the fragments and colonies and completed a daily measurements of light, temperature, salinity and pH. She also cleaned the tanks.

Bleaching score processing

Following Emma Strands Bleaching Score Protocol Emma, Hollie, Kristen, and Danielle have started processing the daily colony photos to track when the ambient and hot colonies start to differ in bleaching score. They have been updating the Photographic Bleaching Script often to make these comparisons and consult on moving forward.

It appears that the bleaching score in the colonies experiencing the heat stress have continued to decline. We see a significant difference in the interaction between treatment and day.

Data tracking

All daily measurements, bleaching score, and survivorship tracking for the colonies and fragments can be found on the Heatwave Google Drive and Gametogenesis GitHub.
