A Stochastic Collision Risk Model for Seabirds in Flight

J. Wilson
Collision Risk Models (CRM) are used to assess impacts on seabird populations in all offshore wind farms Environmental Impact Assessments (‘EIA‘) and Habitats Regulations Appraisals (‘HRA‘) in the UK. Existing collision models are unable to properly incorporate variation or uncertainty in the input parameters into calculations of collision frequency, nor estimate the uncertainty around these values. Uncertainty in predicted collision numbers may result in the delays in the licensing process for offshore wind farms, or...

Contaminant and biological effect data to support MSFD Descriptor 8 1999-2015 by CSEMP Region.

The 2016 assessment of the UK's Clean Seas Environment Monitoring Programme described the status and trends of contaminant concentrations and biological effects measurements in biota and sediment at monitoring stations in waters around the UK. Assessments were made for a large number of time series, typically each of a single contaminant in a single species (for biota) at a single monitoring station. The results of the individual time series at coastal and offshore stations were...

Scottish Coastal Observatory - Stonehaven Site

Samples are collected offshore from Stonehaven using Marine Scotland Science's catamaran, the Temora. The Stonehaven site has many student projects and supplementary projects carried out parallel to the regular monitoring due to its short distance from the Marine Laboratory in Aberdeen. Stonehaven is one of the two full coastal ecosystem monitoring sites in Scotland, the other being Loch Ewe on the west coast. E.g. both sites are being monitored for oceanography, water chemistry, phytoplankton, and...

The Scottish Shelf Model 1990 – 2014 climatology – reduced precision output from version 2.01

Marine Scotland is the custodian of a hydrodynamic model of Scottish continental shelf waters, the Scottish Shelf Model (SSM). The wider Scottish Shelf model (SSM) domain covers the Scottish continental shelf at relatively high resolution (up to 1 km node spacing at the coastline) but also covers most of UK waters, the North Sea and the English Channel. The domain extends in longitude from approximately 13° W to 13° E, including the Baltic Sea. The...

Monitoring of Polycyclic Aromatic Hydrocarbons (PAH) in Scottish Deepwater Environments (MoreDeep)

Polycyclic aromatic hydrocarbon (PAHs) were measured in environmental samples (water, fish and sediment) collected in 2014 and 2016 from the Faroe-Shetland Channel and Rosemary Bank Seamount. These data could be used to provide a baseline against which any changes can be assessed in the event of an oil spill and contribute to any environmental impact assessment. Concentrations in all samples were low, often below the detection limits, and were typical of reference sites. Sponges can...

In the process a significant quantity of additional information has been collected on the nature and scale of discarding in the Scottish mixed whitefish fishery in the northern North Sea. The results have confirmed species such as hake, saithe and cod as some of the biggest components of whitefish discards. They have also indicated that the vast majority of discard...

Swimming Depth of Sea Trout

J. Sturlaugsson
Data on swimming depth of sea trout Salmo trutta (L.) in Icelandic waters was extracted and collated into a suitable format for use in marine renewables risk assessment. The data shows that the fish are close to the surface much of the time, with some time being spent at greater depths.

The Scottish Shelf Model. Part 4: East Coast of Lewis and Harris Sub-Domain

Marine Scotland has led the development of a hydrodynamic model (FVCOM) for the Scottish continental shelf waters called the Scottish Shelf Model (SSM). A series of six reports have been produced documenting the development of the hydrodynamic model. This report is Part 4: East Coast of Lewis and Harris Sub-Domain, documenting the development of this sub-domain model. A companion volume contains additional details on the model development and lessons learned.

The Use of Indicators for Shellfish Stocks and Fisheries: A Literature Review

T. Miethe
In this report, we review the use of indicators in the assessment and advisory process and management of data limited stocks, both fish and shellfish, worldwide. For the purposes of the review, we define an ‘indicator’ as quantifiable information that acts as a proxy for, or can be related to the state of the stock (spawning stock biomass, demographic properties or recruitment) and anthropogenic pressure (fishing mortality). Measured (or derived) regularly, indicators are able to...
