Also giving evidence into the international connectivity through Welsh ports and airports were representatives from Milford Haven Port Authority, Associated British Ports and Stena Line.
Stena Line had earlier cancelled its 0315GMT sailing on Friday from Fishguard, west Wales, to Rosslare, but was still undecided whether the 1430GMT sailing would go ahead.
Irish Ferries' sailings from south west Wales between Pembroke and Rosslare have been cancelled for Friday, while Stena Line said its afternoon sailing from Fishguard was looking unlikely.
The charity conducts monthly surveys from the Stena Europe ferry, and on Wednesday morning, about 10 miles off the Irish coast heading towards Fishguard, they spotted the superpod.
