The report within this series presents results of the surveys in the West of Duddon Sands field in 2012 which represent the first pre-construction (baseline) survey. Some comments on the results are provided; although the focus of the report is on presentation of the results. Detailed data analysis is being undertaken by NIRAS on behalf of WoDS. Ornithological surveys are planned to continue during the operational phase in accordance with the monitoring schedule and as agreed with the relevant statutory authorities. This series also contains the April - September 2012 bird survey data.

Three surveyors were used with two working and one resting in shifts which helped to reduce fatigue that could have affected data quality. Surveyors also swapped sides of the vessel at the start of each shift to reduce surveyor bias. A hand-held GPS with sub-five metre accuracy was switched on at the surveyors’ position for the duration of the survey which recorded position five times every minute and was synchronised to the surveyors’ time pieces. At the end of each survey the GPS was downloaded and the coordinates matched by time to records of birds to provide a position for each sighting. Birds were recorded to species where practicable but were identified as accurately as possible (e.g. ‘tern sp.’) when birds were distant or in poor light. Other records taken included: time of observation; number of individuals; age class; distance from vessel; flight direction and height where appropriate and behaviour including association with vessels or offshore platforms. A total of six surveys were planned in April, May, June, July, August and September 2012. A survey was successfully completed in each of these months. Any cetaceans or seals observed during the surveys were also recorded.
