Description

Original provider: Liz Allan Dataset credits: Ceredigion County Council Abstract: Since 1994, Ceredigion County Council and a network of shore-based volunteer observes have monitored levels of boat traffic and the occurrence of bottlenose dolphins at seven sites on the coast of Cardigan Bay, Wales. We report high rates of site use and site occupancy by this species during the summer. Although trends in site use may not reflect population trends in the wider region, these data were consistent with recent abundance estimates that indicate that the number of bottlenose dolphins using Cardigan Bay is stable or slightly increasing.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 3,621 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Additional Metadata

marine, harvested by iOBIS. Time was not recorded in the original dataset and is filled with 0:00:00.

Purpose

Cardigan Bay is a Special Area of Conservation for bottlenose dolphins and other species and habitats. Recreational boating is known to have the potential to cause disturbance to cetaceans and this monitoring study provides data that underpins the effectiveness of management.
