| Summary: | To better understand the physiological effects of marine invertebrates to changing environmental conditions, long-term monitoring which captures the natural variability of environmental parameters is required. In this way, experimental findings can be related back to field conditions, and better predictions can be made as to how marine invertebrates, particularly in the harsh intertidal, will fair with rising temperature. In May 2020, Cape Sea Urchins, Parechinus angulosus, were collected from intertidal rock pools at Sea Point, which is situated along the southwest coast of South Africa. After chronic incubation in low pH conditions at the Department of Environment, Forestry and Fisheries' (DEFF) Sea Point Research Aquarium, their response to thermal stress was investigated in recent experimental trials. To calculate the thermal window for these marine invertebrates, both habitat temperatures, as well as their threshold temperatures are required. The latter was obtained by examining the Critical Thermal ... : The details of the logger placement is captured in the "README" file. The logger was set to record temperature every 5 minutes. Data were extracted from the logger using HOBOware Pro software and exported into Excel files. Times are GMT+2. The data available are the clean files (i.e. only temperatures recorded once logger was placed in its sun-exposed postion. To avoid the inclusion of any “handling” temperatures in the clean datasets, the temperatures extracted are from ten minutes once loggers are deployed, and 10 minutes before they are removed to download data. ... |
