MRV Alba na Mara

Survey: 1219A

Duration: 25 July – 05 August 2019

Objectives:

Retrieve and deploy a series of acoustic release systems (22 subsurface moorings) with attached acoustic recording devices (22 C-POD, 7 sound recorder) as part of the ECOMMAS (East Coast Marine Mammal Acoustic Study), JOMOPANS (Joint Monitoring Programme for Ambient Noise North Sea) and SSE Seagreen projects (see Tables 1 and  2 and Figures 1 and  2).

Procedure:

Alba na Mara will sail from Fraserburgh on the morning of 25 July and make for the first mooring position. The ultimate order in which the moorings are retrieved and deployed will be dictated by the current weather forecast and the likely shelter that can be provided by the east coast. Accurate position records will be kept detailing where the moorings are eventually replaced as this may differ from the planned position. If all the moorings have been retrieved and deployed before the scheduled end of the trip Alba na Mara will head to Aberdeen Bay to allow scientific staff to retrieve moorings with VR2 salmon detectors between Ythan Estuary and Findon Ness. (See Figure 3)
