Marine Environmental Unit

Marine Environmental Unit

The Marine Environmental Unit at Marine Services, Orkney Islands Council, was set up in 1974, based on the Environmental Impact Assessment of the proposed Oil Terminal planned for Flotta. Orkney Islands Council agreed that a monitoring programme should be established to assess the impact of the Terminal operations on the marine environment of Orkney, and to support the Harbours Department in its obligations to both the Port users and to the Orkney Islands Council as Port Authority and Local Authority.

The Environmental Unit's Aims

Base line information on the marine environment in the event of changes in that environment due to the effect of the port or its users. Continuous monitoring of the marine and shoreline environment is undertaken to identify changes at an early stage; and Sound, scientifically based advice to the Orkney Marine Services Department on the state of and pressures on the Orkney marine environment. The environmental unit recognises that the aquatic environments in Orkney, both marine and freshwater, are a valued fundamental resource, and provides cost-effective advice and assistance to the Marine Services.

Non-native Species Monitoring

As part of Orkney Islands Council's Ballast Water Management Policy, adopted on 10 December 2012, a baseline survey for marine non-native species in Scapa Flow and Loch of Stenness was included.

The 'Monitoring and Recording System for Marine Invasive Non-Native Species; Scapa Flow and Loch of Stenness' report outlined the survey methods to be used during the baseline survey and during the monitoring phase. The baseline survey was conducted in 2012/13 and the on-going annual monitoring was started in 2014.

Marine Intertidal Monitoring

The long term intertidal monitoring programme comprises of 13 sandy shore locations and 21 rocky shore sites.

Sandy shore surveys are carried out annually and include sites in Mainland Orkney, South Ronaldsay and on Hoy. Rocky shore sites are located throughout Orkney and surveys are conducted rotationally every two years.

Water Sample Collection

Since 2002, the Marine Services Environmental Unit has co-operated with Marine Scotland (Science) by collecting marine water samples from Scapa Pier and forwarding them to their laboratory in Aberdeen; this is to assist in the understanding of toxic phytoplankton and to provide samples for nutrient analysis as part of their Long Term Monitoring Programme.

Data from this sampling has been published in ICES Phytoplankton and Microbial Plankton Status Report 2009/2010 which can be accessed here: www.wgpme.net/plankton-status-report .

Wind Data

Marine Services collects wind data from instruments located on the Barrel of Butter in Scapa Flow, the Harbour Authority Building at Scapa, and Kirkwall, Hatston, Stromness, Lyness and North Ronaldsay piers, along with the Sandy Hill radar building on South Ronaldsay.

Although the responsibility for physical maintenance of these has now passed to the maintenance team in Marine Services, the Marine Services Environmental Unit provides data and data analysis for Marine Services and other services within the Council. Live data feeds from the weather stations are provided over the internal network and on the Marine Services' website. The data is available for purchase by third parties.

Contract Work

  1. Shellfish Sampling
    The Marine Services Environmental Unit is contracted by Hall Mark Meat Hygiene Ltd to act as shellfish sampling officers for Shellfish Harvesting Classification areas in Orkney.
  2. Potable Water Testing
    Testing of potable (drinking) water samples by the Marine Services Environmental Unit was started in 2011/12. Currently the Unit tests potable water from all Orkney Ferries vessels, Orkney Towage tugs, Marine Services pilot boats as well as from six piers on the Orkney Mainland.
Jenni

Our Biologist at the Marine Environmental Unit, Miss Jenni Kakkonen, Bsc (Hons), MSc, is currently in process of analysing data collected by the Unit as part of her part-time PhD research with Heriot-Watt University. Data exchange and working collaboratively with Heriot-Watt University, Orkney campus is a requirement for her research.
