The East Coast Marine Mammal Acoustic Study POD dataThe East Coast Marine Mammal Acoustic Study (ECOMMAS) ran from 2013 until 2023. The project’s main aim was to better understand the effects of offshore wind farm construction on marine mammal species off the east coast of Scotland.
Cetacean click detectors (C-PODs and F-PODs; Chelonia Ltd.) were deployed at ~5, ~10 and ~15km from the coast, at 10 locations along the east coast of Scotland between Helmsdale and St.Abbs, at a total of 30 mooring locations. From 2013 to 2015 only one deployment was undertaken each year, covering the summer months. From 2015-2023, two deployments were undertaken per year, covering April to November. Additionally, from 2016-2023, two sites had a third deployment implemented to cover the winter season (Arbroath and Helmsdale). Cetacean click detectors were set up to record continuously and data were processed through the Kerno F classifier v1.0 available at www.chelonia.co.uk.

POD Data for the ECOMMAS monitoring locations

Detections for both narrow band frequency clicks associated with harbour porpoise (Phocoena phocoena), and broadband clicks, associated with delphinid species (Delphinid spp.), were extracted as detection-positive days (DPD) and detection-positive hours (DPH), to quantify dolphin and porpoise presence/absence at each location.

The data contains the following columns:

SiteID = Site identifier

site = Site Name

Latitude = Site Latitude (decimal degrees)

Longitude = Site Longitude (decimal degrees)

YY = Year of observations

Ndays = Total number of days recorded

Porp_DPD = Number of detection positive days for porpoise

PorpDPH_median = Median porpoise detection-positive hours for each site

Porp_Detection_positive = Proportion of porpoise detection-positive days (out of total days recorded, Ndays)

Dol_DPD = Number of detection positive days for dolphin

DolDPH_median = Median dolphin detection-positive hours for each site

Dol_Detection_positive = Proportion of dolphin detection-positive days (out of total days recorded, Ndays)
