Arrivée au fond : 24/05/2006 13:17

Station : Nyegga

Objectifs de la plongée :
Sampling dive of the Nyegga pockmarks G11 and G12.
Exploration transect across pockmark GG.

Resume des travaux:

Pockmarks G11 and G12 surveyed in detail. Pockmarks G11, G12 and GG are similar geological stuctures with also similar-looking seeps.
Several active seeps sampled and documented at G11 and G12 (video observation of active seeps, PEP and CTD methane anomalies). Low strength of seepage, no gas flares. Abundant macrofauna. Numerous macrofauna and meiofauna samples collected. Large fauna diversity. Chemosynthetic species. An active seep site fully documented (at G11): macrofauna and meiofauna collected, chemical environment characterized, video-mosaicking completed,microbiological sampling done.
Two other active sites investigated for microbiological processes and chemical fluxes (one at G11, the other at G12 with MIC deployment).

Numerous small metamorphic clasts sampled at G11 (Origin of the clasts?)

Abundant carbonate crusts suggest large past emissions of methane in the water (When were carbonates formed?)

Pingoes found to be "pillows" of pogonophorans.
