ORCA Oban-Tiree-Coll-Colonsay surveys

A team of up to four trained volunteers including at least one highly experienced observer recorded cetacean sightings using line transect distance sampling methods from a ferry travelling between Oban, mainland Scotland, Tiree, Colonsay and Coll . Two observers searched a 100┬░ area from either side of the ship with a 10┬░ overlap on the trackline to satisfy the assumption that all animals on the trackline are detected while one observer recorded data and the other rested. Effort information including location, vessel speed, course of vessel and environmental conditions (sea state, swell, precipitation, glare and visibility) were recorded every 30 minutes when observers rotate or when conditions changed. Glare was originally recorded as the position of glare in relation to the ship.

Explanation: This data set is conformant with the INSPIRE Implementing Rules for the interoperability of spatial data sets and services

Pass: Yes

Statement: The data was originally either recorded on paper or on tablets with the Logger software. Paper data were entered into an Excel spreadsheet with data rules in place while data collected on tablets were stored in a Microsoft access which were then sent into the ORCA office where it was checked (e.g. checked for spatial errors using GIS software, species identification confirmed with photographs). Once checked, it was assigned survey/effort/sightings IDs and entered into a master spreadsheet.
