Bydd samplu yn cymryd oddeutu 2 ddiwrnod a bydd yn golygu gostwng ac adfer samplwr cydio gwaddod bach mewn lleoliadau ar draws y bae o borth Dinllaen i o amgylch Bar Caernarfon.

Mariners are advised that the vessel Seven Guardian will be undertaking a small-scale scientific survey (grab sampling) from 5th- 21st of April (depending on weather) in the Caernarfon Bay Area including the approaches to Caernarfon. Sampling will take approximately 2 days and will involve lowering and retrieving a small sediment grab sampler at locations across the bay from Porthdinllean to around the Caernarfon Bar.
