Two beds were sampled in Betty’s:

Divers visited this site on 31 May 2015, and the dive for kelp collections was from 10:25 to 10:55. This site is situated at a depth of 8 m and Laminaria and Ecklonia were collected (Laminaria does not occur at shallower depths here). The bottom topography is rocky with large boulders. The boulders have dense beds of Ecklonia on top and on the sides with no Laminaria occurring within these beds. Laminaria occur either at the fringes of these beds or as their own small clumps on smaller boulders and rocks. There is sand between the boulders and rocks.

The next day (1 April 2015), the site was visited again and a reef at 6 m was chosen for the collection of Ecklonia only – this was done to ensure that the depth was commensurate with the collections in False Bay, which are all at a depth of 6 m. The bottom is relatively flat, for a kelp reef, with very few large boulders. The rocky bottom is mostly covered with crusting coralline, sponges or light folios algae. Sandy gullies occur between the rocky kelp beds and tend to be 1 or 2 metres deeper. The overall depth gradually increases away from shore.

The Betty’s Bay collections on 31 May and 1 April 2015 coincided with Ross Coppin’s set-up and sampling of the kelp beds for his MSc.

Kelp collection on 25 March 2015. Ecklonia and Laminaria taken from granite boulders at a depth of ~ 5.5 m. Dive from 12:03 – 12:43 (Robert S and Robert W; Ross and Sam as surface swimmers). The boulders are situated on sand at a depth of approx. 7 m.

Ecklonia occupy the tops of the boulders, while the Laminaria seems to be positioned sparsely and haphazardly in-between as individual plants, usually 1 m lower than Ecklonia. No Laminaria were found within dense beds of Ecklonia.

Kelp collection on 25 March 2015. Ecklonia and Laminaria taken from granite boulders at a depth of ~ 6 m. Dive from 10:19 – 10:42 (Robert S and Robert W; Ross and Sam as surface swimmers). The boulders are situated on sand at a depth of approx. 7 m.

Ecklonia occupy the tops of the boulders, while the Laminaria is positioned as a fringe around the boulders. The tops of the boulders reach up to 5 m and are large flat surfaces. The sides of the boulders steeply slope down to sand at 7 m.

Team Kelp & Co. social

The Dog's Bollocks
The Dog’s Bollocks

Team Kelp & Co. had our first lab social for 2015. Our venue was the Dog’s Bollocks at the Yard in Cape Town, where we stayed from just before 6-pm to shortly after 11-pm. Although the establishment has various items on the menu, it is usually a given that their juicy burgers are the dietary items of choice due to their extremely high palatability; lubrication was provided in the form of the Dog’s Bollocks pilsner hybrid (although legally acquired wine and smuggled vodka were also imbibed).

Sadly not all members of Team Kelp could attend; below are a few choice images of the evening.
