    • Science - Creature Features and Chemosynthesis

      Marine Institute; Tulca (Marine Institute, 2018)
      The Creature Features and Chemosynthesis Presentation is a simple PowerPoint presentation about life in the hydrothermal vent ecosystem. The presentation introduces students to some of the unique creatures that live there and how the vents provide energy for them to survive through the process of chemosynthesis.

      Marine Institute (Marine Institute, 2018)
      The lesson will enable students to listen, imagine and create their own music, inspired by the discovery of the Moytirra hydrothermal vents. The students will select from a wide variety of sound sources such as voice, body percussion, improvised instruments and technology to generate sounds of the deep ocean, to accompany the storyboard/film.
    • English 5th and 6th Class: Storyboard your own deep sea voyage of discovery

      Marine Institute (Marine Institute, 2018)
      The lesson introduces students to how stories are developed for film.

      Marine Institute (Marine Institute, 2018)
      The lesson provides students with an opportunity to learn about people and places in Ireland. With a focus on marine science, the students will learn about the type of work marine scientists are involved with and the environments they work in. By using the famous VENTure expedition where the Moytirra hydrothermal vents field were discovered in the Mid-Atlantic, the students will investigate, record and communicate their findings about scientists such as Dr Andy Wheeler, the chief scientist of this survey. Students can also learn about the people he works with on the research vessel, the RV Celtic Explorer.

    • Summary Report on 2016 Residue Monitoring of Irish Farmed Finfish and 2016 Border Inspection Post Fishery Product Testing undertaken at the Marine Institute

      Marine Institute (Marine Institute, 2018)
      On behalf of the Department of Agriculture, Food and Marine (DAFM), the Marine Institute carries out monitoring of chemical residues in finfish for aquaculture sector. This monitoring is set out in the annual National Residue Control Plan, which is approved by the European Commission, and is an important component of the DAFM food safety controls and is implemented under a service contract with the Food Safety Authority of Ireland. Since 1999, the Marine Institute has implemented the National Residues Monitoring Programme for aquaculture. This is carried out on behalf of the Sea Fisheries Protection Authority, which is the responsible organisation for residue controls on farmed finfish. The outcome for residues levels in farmed finfish during 2016 remains one of consistently low occurrence. In 2016, in excess of 691 tests and a total of 1,933 measurements were carried out on 136 samples (i.e. 126 target samples & 10 suspect samples) of farmed finfish for a range of chemical substances, including banned and unauthorised substances, various authorised veterinary treatments and environmental contaminants.
    • A Low-Complexity Mosaicing Algorithm for Stock Assessment of Seabed-Burrowing Species

      Corrigan, D.; Sooknanan, K.; Doyle, J.; Lordan, C.; Kokaram, A. (IEEE Xplore, 2018)
      This paper proposes an algorithm for mosaicing videos generated during stock assessment of seabed-burrowing species. In these surveys, video transects of the seabed are captured and the population is estimated by counting the number of burrows in the video. The mosaicing algorithm is designed to process a large amount of video data and summarize the relevant features for the survey in a single image. Hence, the algorithm is designed to be computationally inexpensive while maintaining a high degree of robustness. We adopt a registration algorithm that employs a simple translational motion model and generates a mapping to the mosaic coordinate system using a concatenation of frame-by-frame homographies. A temporal smoothness prior is used in a maximum a posteriori homography estimation algorithm to reduce noise in the motion parameters in images with small amounts of texture detail. A multiband blending scheme renders the mosaic and is optimized for the application requirements. Tests on a large data set show that the algorithm is robust enough to allow the use of mosaics as a medium for burrow counting. This will increase the verifiability of the stock assessments as well as generate a ground truth data set for the learning of an automated burrow counting algorithm.
    • International Blue Whiting Spawning Stock Survey (IBWSS) Spring 2018

      Marine Institute; Wageningen Marine Research; Institute of Marine Research; PINRO; Faroese Marine Research Institute; Marine Scotland Marine Laboratory; Johann Heinrich von Thünen-Institut; Danish Institute for Fisheries Research; Galway, Mayo Institute of technology; Irish Parks and Wildlife Service (Marine Institute, 2018)
      Coordination of the survey was initiated in the meeting of the Working Group on International Pelagic Surveys (WGIPS) and continued by correspondence until the start of the survey. During the survey effort was refined and adjusted by the survey coordinator (Norway) using real time observations. The survey design was based on methods described in ICES Survey design Manual (2015). Overall weather conditions were mixed with periods of poor and good weather. All vessels experienced some downtime due to poor weather conditions. The entire survey was completed within 20 days, below the 21 day target threshold.
    • Cruise report: Irish Anglerfish & Megrim Survey 2017

      Gerritsen, H.D.; Kelly, E.; Stokes, D.; O'Hea, B.; Ni Chonchuir, G. (Marine Institute, 2018)
      The 2017 Irish Anglerfish and Megrim Survey (IAMS) took place from 14th February to 7th March (area 7bcjk) and 8-17th April 2017 (area 6a) on RV Celtic Explorer. The main objective of the survey is to obtain biomass estimates for anglerfish (Lophius piscatorius and L. budegassa) and establish an abundance index for megrim (Lepidorhombus whiffiaginis and L. boscii) in areas 6a (south of 58°N) and 7 (west of 8°W). Secondary objectives are to collect data on the distribution and relative abundance of anglerfish, megrim and other commercially exploited species. The survey also collects maturity and other biological information for commercial fish species. The IAMS survey is coordinated with the Scottish Anglerfish and Megrim Survey (SIAMISS) and uses the same gear and fishing practices.

    • Cruise report: Irish Beam trawl Ecosystem Survey 2017

      Gerritsen, H.D.; Moore, S.J. (Marine Institute, 2018)
      The second annual Irish Beam trawl Ecosystem (IBES) took place from 7-16th March 2017 on RV Celtic Explorer in the western Celtic sea. The main objective of the survey is to connect the Irish Anglerfish and Megrim Survey (IAMS) to the UK beam trawl surveys in the Celtic Sea, English Channel and Irish Sea, with the purpose of providing a swept-area biomass estimate for anglerfish (Lophius piscatorius and L. budegassa) in area VII. Secondary objectives are to collect data on the distribution and relative abundance of commercially exploited species as well as invertebrates and by-catch species, particularly vulnerable and indicator species. The survey also collects maturity and other biological information for commercial fish species in the western Celtic Sea. The IBES survey uses the same gear, methods and stratification as the CEFAS Q1 South-west Ecosystem Survey (Q1SWECOS). The IBES survey is formally coordinated by the ICES Working Group on Beam Trawl Surveys
