Abstract

This report is of the CEND 23/15 survey which was undertaken to contribute to the development of a monitoring time-series for Croker Carbonate Slabs cSAC/SCI.

Summary

The monitoring survey of the Croker Carbonate Slabs candidate Special Area of Conservation (cSAC) and Site of Community Importance (SCI) was carried out from 24 October – 06 November 2015. Indicators of the presence of methane, including active gas seabed seepage, and extensive formations with the appearance of Methane-Derived Authigenic Carbonate (MDAC) were identified. Samples of this potential MDAC were collected using a mini-Hamon grab from a number of stations across the site.
