title: Short-term observations of daily currents on the continental shelf and slope off Port Edward, along the east coast of South Africa at location P2 (April 2006 - September 2006)

description: Processed magnitude and direction of daily currents throughout the water column (13.53 - 65.53m).
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 magnitude and direction of daily currents throughout the water column (13.53 - 65.53m) from an ADCP at location P2 (31.19728°S; 30.17488°E) on the inner shelf off Port Edward, between 11 April 2006 and 09 September 2006.
description: A bottom-mounted, upward-looking, 600 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was configured with a bin size of 2 m and a blanking distance of 0.9 m, and deployed at location P2 (31.19728°S; 30.17488°E), on the inner shelf just south of Port Edward, along the east coast of South Africa. The instrument measured hourly magnitude and direction throughout the water column (13.53 - 65.53 m) between 11 April 2006 and 09 September 2006. These hourly values were corrected for magnetic declination, and then averaged to daily means for each depth bin. Only hourly values which showed ≥ 75 % good beam data were used, and daily values were only generated for days on which there were 75 % or more hourly readings.

title: Raw seawater temperature data from the long-term monitoring of the microhabitats of intertidal invertebrates in Sea Point, 08 October to 01 February 2022

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. Three prominent rockpools were chosen in Sea Point, Cape Town (>5 m apart) to install HOBO TidbiT temperature loggers. Two loggers were placed in each pool. Here we present the raw 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 08 October 2021 to 01 February 2022.
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).

The instrument measured hourly temperature readings between 07 September 1999 16h00 and 23 February 2000 11h00.

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.
