More biomineralisation….

Finishing off my experiments in Jerusalem. The right image shows the aragonite skeleton forming under the coral tissue (visible as a grey film just covering the crystals) and the left image shows the distribution of the dye calcein (bright = dye, dark = no dye). Calcein is membrane impermeable and it is present in seawater (bottom left corner) and where seawater has been transported under the tissue (bright ends of some crystals).

Coral imaging

21 March 2018 – I’m working at the Hebrew University in Jerusalem with Jonathan Erez. We are growing corals over glass slides and using an inverted microscope to study the formation of the aragonite skeleton in real time. na1

NERC Ion microprobe facility

I’m having a quiet Monday evening running the ion probe in Edinburgh, looking at the effects of ocean acidification on coral biomineralisation. It’s just me and the corals…

A busy May 2017

NERC have allocated me beamtime at the Ion Microprobe Facility at Edinburgh University to investigate how increasing seawater temperatures and pCO2 affect the chemistry of coral calcification fluids and thereby impact coral reef accretion. Also a big thank you to MASTS for partially funding the purchase of a new dissolved oxygen meter for the coral lab.
