title: Sun exposed temperature data from Sea Point, 07 September to 08 October 2021

description: Conservation Physiology Programme
description: 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 Forestry, Fisheries and the Environment's (DFFE) 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 Maximum temperatures (CTmax), i.e. the temperatures at which organisms respond with uncoordinated mobility, whereas habitat temperatures are available through the deployment of temperature loggers in the intertidal pools inhabited by these organisms. Apart from rockpool temperatures recorded in Sea Point, Cape Town, a HOBO TidbiT temperature logger was also installed on a nearby structure: 33.92074 S, 18.38051 E to record temperature in a sun-exposed position. An alternative to placement on fully exposed rocks where it would be subjected to theft.This data will allow for an indication of the most extreme temperatures in the vicinity of the pool. Here we present the cleaned up version of the temperature measurements from the 07 September to 08 October 2021.
description: 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.

title: Short-term observations of daily bottom temperatures on the continental shelf and slope off Port Edward, along the east coast of South Africa at location P1 (April 2006 - September 2006)

description: Processed daily bottom temperatures from an ADCP at a depth of 34m at location P1 (31.17842°S; 30.15273°E).
description: Between 2005 and 2015, multiple short-term studies were conducted to determine the characteristics of moorings deployed in a region heavily influenced by the strong Agulhas Current, and to examine circulation patterns across the continental shelf and slope off Port Edward, along the east coast of South Africa. Three moorings (P1, P2, and P3) were deployed, just south of Port Edward at depths of 36m, 64m, and 162m, respectively, between September 2005 and September 2006, to measure currents and bottom temperatures across the inner shelf. A further three moorings (P4, P5, and P6) were deployed off Port Edward over the period September 2010 to June 2015, at depths of 217m, 1060m, and 2000m, to measure currents and sub-surface temperatures across the outer shelf and slope. Here we present processed daily bottom temperatures from an ADCP at a depth of 34m at location P1 (31.17842°S; 30.15273°E) on the inner shelf off Port Edward, between 11 April 2006 and 08 September 2006.
description: A bottom-mounted, upward-looking, 600 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was deployed at location P1 (31.17842°S; 30.15273°E), on the inner shelf just south of Port Edward, along the east coast of South Africa. A temperature sensor on the instrument measured hourly temperature readings between 11 April 2006 and 08 September 2006, at a depth of 34m. These hourly values were averaged to daily means. Daily values were only generated for days on which there were 75 % or more hourly readings.

title: Seawater temperature in the microhabitats of intertidal marine invertebrates in Sea Point, 07 July to 07 August 2021

The latter was obtained by examining the Critical Thermal Maximum temperatures (CTmax), i.e. the temperatures at which organisms respond with uncoordinated mobility, whereas habitat temperatures are available through the deployment of temperature loggers in the intertidal pools inhabited by these organisms. Three prominent rockpools were chosen Sea Point, Cape Town (>5 m apart) to install HOBO TidbiT temperature loggers. Two loggers were placed in each pool. Here we present the cleaned up version of temperature measurements from Pool 1: 33.920317 S, 18.379417 E, logger 10687237 and 20195550; Pool 2: 33.920267 S, 18.379417 E, logger 10687240 and 20195543; Pool 3: 33.920167 S, 18.379717 E, logger 20195539 and 20195574, from 07 July to 07 August 2021.
description: The details of each pool are captured in the 'README' file. The loggers were set to record temperature every 5 minutes.The current design is attaching loggers via cable ties to I-bolts drilled into the substrate. All loggers were positioned facing the sea. Data were extracted from the loggers using HOBOware Pro software and exported into Excel files. Times are GMT+2. The data available are the raw files (all temperatures even outside of the rockpools) and 'clean' files where only the temperatures recorded once loggers were placed into the rockpools are provided. Only where possible, data were downloaded and loggers deployed on a monthly basis. Nonetheless, clean data are presented on a monthly basis for each pool (x2 loggers per pool). Where required, 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.
