Marine Science

SEPA’s Marine Science Section monitors and assesses the quality of Scotland’s estuaries and coastal waters. We do so in partnership with Marine Scotland and Scottish Natural Heritage to meet the UK and Scottish Governments’ vision of maintaining “clean, safe, healthy, biologically diverse and productive marine and coastal environments, managed to meet the long term needs of nature and people”.

The unit has about 45 staff located in Aberdeen, Dingwall, East Kilbride and Edinburgh, with boat crew based in Inverkeithing and Troon. Staff are organised into 3 units under the headings of Marine Chemistry, Marine Ecology and OceanMet (Oceanography/Meteorology and Modelling).

The monitoring work carried out by Marine Science focuses mainly on the chemical and ecological requirements of European Union (EU) directives within three nautical miles of the shore. This includes the former dangerous substances and shellfish waters directives, which are now both part of the Water Framework Directive (WFD), and the urban waste water treatment and nitrates directives. Results from this work are used in WFD classification, reported annually to the Scottish Government and submitted to the EU. Results are also submitted to UK marine data archive centres for use in OSPAR (Convention for the Protection of the Marine Environment of the North-East Atlantic) assessments. Some of the data will also be used to provide information for the Marine Strategy Framework Directive.

OceanMet staff use their knowledge of the physical environment in marine waters and mathematical computer modelling to provide advice to external customers and SEPA’s environmental protection staff on the dispersion and dilution of effluents. Similar work for pollutants released to air is carried out by meteorologists in the OceanMet Unit.

Providing expertise and advice on a wide range of issues is a significant part of the work of Marine Science staff. This ranges from regulatory support advice for SEPA colleagues and answers to freedom of information (FOI) enquiries, to responses to specific industries and evidence to the Scottish Government to support policy development.

The Marine Science Section uses a wide range of new technologies including environmental genomics and ferry box technology. We also contribute to a wide range of marine issues, including biodiversity, hydromorphology, emergency planning, UK and Scottish monitoring strategies and research and development.
