title: Short-term observations of daily bottom temperatures on the continental shelf off Natal Bight, along the east coast of South Africa at location Dbn01 (March 2010 - September 2010)

description: Short-term observations of daily bottom temperatures on the continental shelf off Natal Bight, along the east coast of South Africa at location Dbn01 (March 2010 - September 2010)
description: Between 2009 and 2013, multiple short-term mooring deployments were conducted to determine the oceanographic characteristics and variability along the KwaZulu-Natal (KZN) Bight, along the east coast of South Africa. One mooring (Sez01) was deployed off Sezela, about 79km south of Durban, at a depth of 30m, between June 2009 and July 2010. Three moorings (Dbn01, Dbn02, and Dbn03) were deployed off Durban at depths of 50m, 420m, and 570m, respectively, between January 2009 and September 2010, and two moorings (RiB01 and RiB02) were deployed off Richards Bay at depths of 30m and 580m, respectively, between February 2009 and September 2010. These moorings measured currents, as well as sub-surface and bottom temperatures across the continental shelf and along the continental slope of the KZN Bight. Here we present processed daily bottom temperatures (40.7m) from an Acoustic Doppler Current Profiler (ADCP) at location Dbn01 (29.90°S; 31.07°E) on the continental shelf off Durban, between March 2010 - September 2010.
description: A bottom-mounted, upward-looking, 300kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was configured with a bin size of 2m and a blanking distance of 2m, and deployed at location Dbn01 (29.90°S; 31.07°E), on the continental shelf of Durban. The instrument measured hourly bottom temperatures (40.7m) between 01 March 2010 and 5 September 2010. These hourly values were then averaged to daily means, and daily values were only generated for days on which there were 75% or more hourly readings.

Here we present raw data from an Acoustic Doppler Current Profiler (ADCP), deployed at a depth of 573m, at location RiB02 (29.02°S; 32.26°E) on the continental slope off Richards Bay, between  September 2009 and February 2010.
description: The raw data was collected using a bottom-mounted, upward-looking, 75kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was configured with a bin size of 16m and a blanking distance of 5m, and deployed at location RiB02 (29.02°S; 32.26°E), on the continental slope of Richards Bay. The instrument measured hourly magnitude and direction throughout the water column between 30 September 2009 and 25 February 2010.

title: Experimental manipulations of the density of Cymbula granatina on rocky shore community

description: Rocky Shore data.
description: Densities of a commonly-harvested intertidal limpet Cymbula granatina were manipulated at two sites within a no-take marine protected area on the west coast of the Cape Peninsula in South Africa, using four treatment levels ranging from zero to maximum natural densities, together with control plots, to evaluate the effects of different harvesting intensities on rocky shore community composition. Following removal or thinning of C. granatina, community composition changed: cover of corticated and ephemeral algae increased and recruitment of C. granatina decreased. These outcomes were, however, dependent on the time frame considered, as algae underwent an annual cycle, and the effects of limpet removal were evident predominantly during the summer upwelling season when the algae proliferated. The management implications of the results of this experiment are discussed.
description: To evaluate the effects of variable densities of C. granatina on rocky shore communities, a herbivore exclusion experiment was set up in November 2017, in which this limpet was excluded or thinned to fixed proportions of normal densities inside 30 x 30-cm plots. To simulate different levels of exploitation and control for potential side effects arising from the experimental procedure, the experiment had three types of exclusion treatments: a cage treatment (C), a semi-fenced treatment (SM) and an unfenced treatment (U), with treatments having four density levels that were each replicated four times (Fig. 1). The levels were: (a) 100% of natural densities (>12 individuals/plot, control) where no reduction of density was undertaken, (b) 50% (7-9 individuals/plot, lightly harvested), (c) 10% (single limpet/plot, heavily harvested) and (d) 0% (no limpets/plot, depleted). These levels are henceforth referred to as C100, C50, C10 and C0, respectively, for the cage treatment. Equivalent densities were established for the unfenced treatment. The semi-fenced (SM) treatment had two density levels only, 100% (SM100) and 0% (SM0) of natural densities of C. granatina because of time constraints on sampling during low tide and because we assumed that examining the extremes of density would be sufficient to test for caging effects. The total number of experimental units was thus 40 per site, for 10 treatment/density combinations. The use of three exclusion methods allowed me to control for possible caging effects, such as any influence of the caging materials and of wave reduction. Specifically, cages vs. semi-fences were compared to test for wave-reduction effects, and semi-fences vs. unfenced to test for cage-material effects.

title: Short-term observations of daily bottom temperatures at the Walters Shoal, southwest Indian Ocean at location WSS01 (30 May 2014-01 August 2015)

description: Short-term observations of daily bottom temperatures at the Walters Shoal, southwest Indian Ocean at location WSS01 (30 May 2014-01 August 2015)
description: The Walters Shoal project, part of the broader African Coelacanth Ecosystem Programme (ACEP III), conducted an oceanographic and biological survey of the Walters Shoal, a shallow seamount in the southwest Indian Ocean, in order to understand the biodiversity and ecological processes occurring on this unique seamount. The project used a multidisciplinary approach that included the sampling of sponge fauna, fish populations, and oceanographic conditions. Oceanographic data (including moored ADCP data, CTD profiles, as well as underway S-ADCP and TSG data) was collected to understand the circulation patterns and hydrography that could influence the biological communities on the seamount. Here, we present the moored ADCP data that was collected to determine currents and sub-surface temperatures. Two ADCP moorings were deployed, one on the northern part and the other on the southern part of Walters Shoal, at depths of 500m, between May 2014 and August 2015. Here we present processed daily bottom temperatures from an ADCP at location WSS01 (33.29°S; 43.90°E) on Walters Shoal, between 30 May 2014 and 01 August 2015.
