These figures compare favourably with our European counterparts, reflecting a high level of activity on national and international research and monitoring programmes.

Work duties in 2011 for the Galway based vessels will range from fisheries surveys to underwater mapping and from climate studies to deepwater surveys with the remotely operated submersible ROV Holland 1. The work schedule will facilitate training missions and to carry out essential maintenance work on Ireland's network of data buoys that, in parallel to their research function, supply the vital information on which weather and shipping forecasts are based.

The increased activity of the research vessels reflects the growing imperative to understand and sustainably manage the economic potential of our offshore marine territories, an area over ten times that of Ireland itself.

A major role of the ships' workload will be commercial fish stock assessments. Together they are to devote 141 days on stock surveys in support of the sustainable management of Ireland's fisheries.

The RV Celtic Voyager will conduct underwater television surveys of valuable prawn stocks off the Aran Islands, the Irish and Celtic Seas, working on blue whiting, a survey of herring stocks in the north-west. In addition a comprehensive 54-day annual Irish Groundfish Survey which will take place in stages all around the Irish coast from September to December.

The survey will be the largest undertaken by an Irish research vessel and is essential to providing the scientific data used to inform the annual quota negotiations required in Brussels each year.

At 65.5m RV Celtic Explorer (2,425grt) accommodates 35 personnel and up to 21 scientists and 31.4m RV Celtic Voyager (340grt) with up to 8 scientists and a maximum endurance of 14-day days.
