European Plans for the Ocean Energy Sector – October 2014

The European Commission has developed a two-step action plan to support the emerging ocean energy sector in Europe. In the first phase (2014 – 2016), an Ocean Energy Forum will be set up, which will bring together stakeholders to develop a shared understanding of the problems and to develop solutions. It will focus on building capacity and critical mass, and on fostering cooperation. The outcomes of the Forum will feed into a strategic roadmap, which will provide an agreed blueprint for action in order to help the ocean energy sector move towards industrialisation.

In the second phase (2017 – 2020) a European industrial initiative could be developed, based on the outcomes of the Ocean Energy Forum. European industrial initiatives are public-private partnerships that bring together industry, researchers, Member States and the Commission to set out and implement clear and shared objectives over a specific timeframe. They enhance the impact of innovative research and development and provide a platform for sharing investment risk.

The development of the Ocean Energy Forum is still at an early stage. However, it is proceeding against an ambitious agenda set by the Commission to develop 100GW of ocean energy by 2050. In support of this agenda, a comprehensive infrastructure fund will be put in place to tackle issues such as the provision of a strategic grid network.

MRV Alba na Mara: Survey 1714A – Cruise Report

“Consider the subtleness of the sea; how its most dreaded creatures glide under water, unapparent for the most part, and treacherously hidden beneath the loveliest tints of azure”. Herman Melville, Moby Dick.

A good book on a long sea trip is often a good source of inspiration. Finding and identifying rare marine species hidden beneath the azure of the Sea of the Hebrides is not, as might be expected, an easy task, but for the last three weeks the Alba na Mara has been doing just that.

When the capricious weather has decided to be kind, and at times it seldom felt like it would, we used the ship’s underwater camera system to survey several sites across the Sea of the Hebrides.  Some of these sites were home to the tall sea-pen, Funiculina quadrangularis, and during the trip we were able to locate several areas that were previously unknown to science. Our other search for the UK’s largest and rarest bivalve mollusc, the fan mussel, Atrina fagilis, was guided by computer models developed jointly by Marine Scotland and Aberdeen University. Our journey has taken us to waters over 240m in depth and to seabed varying from deep mud to rocky cliffs. Our efforts look promising but the task of revealing the sea’s hidden treasures is always a difficult one.

MRV Alba na Mara: Survey 1714A – Cruise Programme

Figure 1 - Map of the study area in the waters around the Isle of Skye
Figure 1 – Map of the study area in the waters around the Isle of Skye
Duration:

26 September – 14 October 2014

Ports: Loading in Fraserburgh, 24 September 2014 and unloading in Greenock, 14 October 2014

Personnel: Five

Gear:

  • Pyramid frame and underwater video camera kit.
  • Pyramid frame calibration mesh (2 x wire panels)
  • Large, dual bongo + counterweight + 200 µm net and cod ends
  • Large plastic fish tank (white) + grey fish tanks
  • Scanmar depth units (x2)

 

Objectives

Benthic Survey of Burrowed Mud Habitats

1714A will survey the waters around the Marine Protected Area (MPA) sited at the island of Canna (Figure 1).  Video surveys of the seabed will be carried out during this work in addition to the collection of RoxAnn sediment data.  It is the primary objective of this cruise to survey monitoring sites previously surveyed in 2012 and 2013 that support Scotland’s Priority Marine Features.  Work from these surveys will be used to determine the effect of MPAs established in Scottish waters.  A secondary objective will be to survey additional sites in the area surrounding the Small Isles and another to the north of the Isle of Skye that could provide suitable substrate for the tall sea pen, Funiculina quadrangularis, and for the fan mussel, Atrina fragilis.  These data, in conjunction with data gathered from less suitable sites, will be used to refine habitat suitability models for these species.  Species type, species densities and substrate type will be recorded during the survey.  Further post survey analysis will be conducted on this data.

Larval Dispersal

1714A will sample plankton from the water around Canna.  The programme of work follows on from plankton surveys conducted in June 2012 (survey 1012A), and September 2013 (1213A). Sampling will be conducted using the large (1 m diameter) dual bongo net.

Further to this work, 1714A will also retrieve a spat collecting mooring from Canna which was deployed from the MV Spanish John II on the 29April 2014. Candidate A. fragilis spat found on the spat collectors will be measured, weighed and placed in holding tanks for further cultivation in the laboratory.

8th International GIScience conference

In September, Marine Scotland Science staff attended the 2014 8th International Conference on Geographic Information Science (GIS),. The biennial conference, held in Vienna and hosted by the Austrian University of Technology brought together more than 600 international participants from academia, industry, and government organisations to discuss the state-of-the-art advances in the field of GIS.

This year’s programme provided a platform for geographers, computer scientists, and cartographers to meet with GIS practitioners such as ecologists, traffic specialists, linguists and social scientists. The 3-day long programme, combined with 1-day pre-conference workshops, included a number of different sessions in movement analysis, land use & land cover, mapping, spatial analysis and modelling, time geography, user generated data, volunteering GIS and public participation GIS.

Renowned Professors Edelsbrunner, Sieber, and Dykes were invited to deliver keynote talks on topology, citizen science and geo-visualisation respectively and in total, more than 100 presentations were given.

A brief overview of selected presentations from the conference and movement workshop is provided here.

A map of the three survey areas in and around Lamlash Bay: 1) western area of Lamlash Bay 2) no take zone 3) outside reference area. Four quadrat images are to be taken at each station (n=30).

Duration: 16-24 October 2014

Sampling Gear:

  • Pyramid frame
  • 2 x UW TV cables (one armoured)
  • Digital stills camera
  • AV support equipment

 Objectives

1. Collect time series data on scallop abundance in the Lamlash Bay area

In September 2008 part of Lamlash Bay, Arran, became a community marine reserve and is now a No Take Zone (NTZ), the purpose of which is to help protect and enhance biodiversity.  In addition to the enhanced biodiversity there is also an expectation that the No Take Zone will result in the scallop stocks being enhanced.  Two baseline surveys, conducted by Marine Scotland Science in June 2009 and November 2010, collected data on scallop abundance in and around the waters of the NTZ.  This survey will repeat the survey of the NTZ and two control areas (Figure 1) in order to assess whether changes have taken place in the structure of the benthic community in the intervening four years.

2. Conduct a bathymetric study of the area to the south of Arran MPA

The area to the south of Arran will be surveyed using multi-beam, bathymetric techniques.  Data from this survey will be processed at a later date and will be used to derive sediment maps.
