PurposeResearch
ObjectivesAim

Contribute to the development of a monitoring time-series for Croker Carbonate Slabs SCI from which the rate and direction of change in the condition of submarine structures made by leaking gases can be inferred in the long term.

Plan

The cruise will leave Swansea Port around 13:00 on the 24th October and will return to Swansea on the 6th November. Currently transport and mobilisation of kit at the vessel is arranged.

The aim of the primary Croker site is to explore the presence and extent of methane derived authogenic carbonate (MDAC). This will require a multidisciplinary approach to operations. Primarary objectives will be achieved using acoustic techniques (MBES, sidescan sonar and boomer) and ground truthing (Hamon Grab, Niskin bottles, drop camera and rock dredge). A rough time estimate of time commitment to each can be found in the table below along with the rough planned locations in the figure below that.
