MRV Alba na Mara Survey 0417A Programme

March 24, 2017 by No Comments

Duration: 25 March – 03 April 2017

Gear: Surface and subsurface PAM moorings

Objective:

To deploy a series of moorings comprising dhan buoys (9 surface marked moorings) and acoustic release systems (21 subsurface moorings) with attached acoustic recording devices (30 C-POD and 10 SM2M) as part of the east coast marine mammal monitoring programme (see Table 1 and Figure 1).

Procedure:

Loading of all equipment will be carried out on 22 March. Alba na Mara will sail from Fraserburgh on the morning of 25 March and after all required drills make passage for the first mooring position.  The ultimate order in which the moorings are 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 placed as this may differ from the planned position.  If all the moorings have been deployed before the scheduled end of the survey Alba na Mara will carry out range-testing of acoustic salmon tags using a moored system already deployed within Aberdeen Bay.
