Transplant experiment at Panarea - 10-16 July 2010
Zvy Dubinsky,
Oren Levy, Michal Grossowicz (Bar Ilan University) and Stefano Goffredo, Erik Caroselli and
Bruno Capaccioni (University of Bologna) set a coral transplant experiment
along a pH gradient inside an underwater volcano crater at Panarea, for
studying the effects of ocean acidification on Mediterranean corals.
This clip documents
the transplant experiment in the crater.

Some pictures of the surroundings.
The "Pietra Nave", where the corals to be transplanted have been
collected.
Stefano Goffredo and Oren Levy prepare for diving.
Leptopsammia pruvoti.
It was very common in the island.

Gone samplin'.
Pelagia nocticula always accompained us in the mission.
Panarea underwater...
...is full of fish.

light!
The boxes with tiles inside the crater.
Fixed directly on the rock.
CO2 bubbles coming out of
the crater acidify the surrounding water.
The whole surroundings are full of gas
emissions.
Close to the main emission fluxes,
colonies of sulfur bacteria flourish.

The experiment is set.
Bottles and syringes for water analyses.

This amount of bubbles identifies the
center of the crater.
Water is so acid that you can feel the
low pH on your skin.

The crater.
Close to the crater, another violent
gas emission exists, and this is also hot! Unfortunately, no temperature
gradient exists in this point.
