CE0916 Irish Groundfish Survey Leg 1

This survey was conducted on board the RV Celtic Explorer in 2009 by the Marine Institute (MI) as part of the annual groundfish survey to determine the distribution and abundance of commercial fish around Ireland.     The Irish Groundfish Survey (IGFS) forms part of the International Bottom Trawl Survey (IBTS) programme, an international survey effort coordinated by the International Council of the Exploration of the Sea (ICES). Each year the survey, taking place in Autumn/Winter, collects demersal trawl and ancillary data in Irish waters to produce relative abundance indices for fisheries management.  In particular the survey provides an index of the share of young fish in the stock, which in turn gives an indication of its spawning success. The IGFS contributes to Ireland’s international obligation to supply scientific data that support the implementation of the Common Fisheries Policy (CFP).     This survey is a series of demersal sampling trawls at pre-defineds stations. The 2009 survey took place over 3 legs. Leg 1 focused on the northerly ICES Area and took place in late September and early October, while Leg 2 in the western and southern areas was carried out during November/December.    In order to make data as comparable as possible, each survey operates under a set of agreed standard protocols. Each tow is 30min long and takes place during daylight hours at 3.5-4 knots. Net geometry and ground contact is monitored and logged. All fish and commercial shellfish are sorted to species level prior to taking lengths and other biological measurements such as age, sex and maturity. The primary purpose of the Irish Groundfish Survey is to develop estimates of juvenile abundances for important commercial fish species. Measurements of the abundance of juvenile fish are a critical measure of the health of a stock, serving as an annual indication of recruitment (the number of newly spawned fish which enter the population each year) success or failure. Most importantly, they allow forecasting of future commercial abundance. In addition, the Irish Groundfish Survey provides data on the distribution and biology of commercial and non-commercial species of ecological interest, as well as hydrographic and environmental observations.

CE0912 North-west Herring Acoustic Survey

This survey was conducted by the Marine Institute on-board the RV Celtic Explorer in summer 2009 as part of the North West Herring Acoustic Survey.     The northwest and west coast (ICES Divisions VIaS and VIIb) herring acoustic survey programme was first established in 1994. This survey represents the second in the new time series. In 2004, a single spawing stock survey was carried out early in quarter 1 and continued until 2007. It was then decided that the survey should be incorporated into the larger coordinated Malin shelf survey in 2008.     The survey was coordinated through the ICES Working Group of International Pelagic Surveys (WGIPS). Survey data on stock numbers at age are submitted to the ICES Herring Assessment Working Group (HAWG) and used in the annual stock assessment process.     The northwest and west coast (ICES Divisions VIaS and VIIb) herring stock is composed of two spawning components, autumn and winter spawners. Spawning covers a large geographical area and extends over a 4-month period from late September through to late March. Traditionally, fishing effort has been concentrated on spawning and pre-spawning aggregations. The autumn spawning component, which mostly occurs within VIIb and VIaS, feeds along the shelf break area to the west of the spawning grounds. The winter spawning component is found further north in VIaS. In VIaS, summer distribution extends from close inshore to the shelf break. Components of the winter spawning fish are known to undertake northward feeding migration into VIaN before returning in the winter to spawn along the Irish coast.    This survey, carried out between 3rd - 22nd July, focused on the northwest and west coast of Ireland. To keep in line with existing survey methodology acoustic data collection was only undertaken during daylight hours (04:00 and 00:00). A systematic parallel transect design was adopted with a randomised start point. Transects were positioned running perpendicular to the lines of bathymetry where possible.    The acoustic data were collected using the Simrad ER60 scientific echosounder. For biological sampling, a single pelagic midwater trawl was used. 31 hauls were carried out. All components of the catch from the trawl hauls were sorted and weighed; fish and other taxa were identified to species level. Oceanographic stations were carried out during the survey at predetermined locations along the track. The aim of the acoustic survey is to determine the relative abundance of the target species, herring. This information is then used to determine catch rates and management advice for the following year.    Other objectives include collecting physical oceanography data (CTD).

CE0903 Marine Institute Celtic Explorer Oceanographic Survey North East Atlantic Ocean 2009

In order to begin to collect key oceanographic data two dedicated research cruises are conducted annually in the Irish region. The foundation of these cruises is the acquisition of oceanographic data such as temperature, salinity, dissolved oxygen, fluorescence and ocean currents. A cross service group function was introduced by acquiring phytoplankton, zooplankton, and fish larva samples and gathering bathymetric data (including ground truthing samples) for the INFOMAR seabed mapping project.     This inter-institutional and multi-disciplinary survey, led by the Marine Institute and National University of Ireland, Galway (NUIG), was conducted in February 2009 on board the R.V. Celtic Explorer. The main purpose of the cruise was to examine hydrographic conditions in Rockall Trough. A total of 43 stations were surveyed for a variety of parameters including CTDs (Conductivity-Temperature-Depth), grab samples and cores, nutrients, salinity and phytoplankton. Four ARGO floats were also deployed. The main purpose of the cruise was to examine hydrographic conditions in Rockall Trough. Objectives included:  •	Collect CTD profile data along the standard offshore sections to include:  o	Nutrient sampling  o	Phytoplankton and chlorophyll samples  o	Salinity samples  •	Collect grab samples at key locations on the Irish shelf  •	Collect opportunistic Vibro cores at sites in the vicinity of Porcupine and Rockall Bank.  •	Deploy 4 ARGO floats in the Rockall Trough  •	Collect zooplankton net hauls from around the Rockall Trough

CE10009 Celtic Explorer Cetaceans on the Frontier Cruise North East Atlantic Ocean 2010

This main aim of the survey, led my Galway-Mayo Institute of Technology, was to conduct a habitat specific survey of deep diving cetaceans. The survey was conducted on board the Marine Institute’s R.V. Celtic Explorer as a dedicated survey between 18th February and 1st March 2010. The survey area covered waters over the Porcupine Bank, Porcupine Seabight, Whittard Canyon System and Celtic Shelf.     The survey vessel travelled at an average speed of 8 knots while on transect, except in heavy swell. The ship spent from 08:30 – 18:30 each day on visual and acoustic transect, and from 20:30 – 08:30 altered between steaming at 8 knots and being stationary while conducting CTDs (Conductivity Temperature Depth), water sampling and plankton hauls.     An acoustic survey was carried out using a towed hydrophone array. Acoustic data from bottlenose dolphin (Tursiops truncatus) encounters were recorded using passive acoustic techniques and provided to a PhD study (based in University College Cork). Visual seabird surveys and megafauna surveys were also conducted on this cruise, as well as the deployment of an argo float. As the primary purpose of the cruise was to record the distribution of cetaceans using visual and acoustic techniques, oceanographic work was conducted only after sunset. 28 oceanographic stations were sampled. Due to the time taken to conduct vertical profiles of zooplankton at some stations, CTDs were not conducted at all stations but at least one CTD was conducted at each canyon/location. CTDs were conducted at 29 stations. Salinity, temperature and fluorescence were measured under way using the ship’s onboard fluorometer and CTD. To conduct a habitat focused, double platform, absolute abundance survey of cetaceans (and marine megafauna, including seabirds) in key habitats for deep-diving species on the slopes and canyon systems of the Porcupine Bank and Sea Bight.  To sample the for phytoplankton, zooplankton and krill which form the basis of the food chain which supports cetaceans, seabirds and other marine megafauna in these habitats.

CE10008 Glacial and non-glacial sediment transport in the Rockall Trough and Porcupine Bank (North Atlantic Ocean)

Submarine landslides are the dominant sediment transport mechanism on continental margins, transferring volumes in the order of tens to hundreds of cubic kilometres from the continental slope to as far as the deep abyssal plain. Submarine landslides are known to be capable of destroying marine infrastructure such as submarine telecommunication cables and oil platform installations.    The Rockall Trough and its margins, a relatively lightly-studied area, form a valuable natural laboratory holding information on slope stability, sediment transport, bottom ocean currents, and ice-sheet history. The primary aim of this cruise will be to intensively core a small basin on the southeast margin of the RT, with the intention of determining the frequency of slope instability on the opposite margin and aid assessment of potential tsunami hazards and characterising deep-water gravity flow processes and deposits in a narrow basin and the effect this has on flow transformation processes.     This survey, led by University College Dublin (UCD), took place in June 2010 on board the Marine Institute&#039;s R.V. Celtic Explorer. The primary aim of this cruise was  to intensively core a small basin on the southeast margin of the RT, with the intention of determining the frequency of slope instability on the opposite margin and aid assessment of potential tsunami hazards and characterising deep-water gravity flow processes and deposits in a narrow basin and the effect this has on flow transformation processes.  Piston corers and  Vibrocores were completed during the survey. The objectives of the survey to 1) study  submarine landslide deposits and especially their timing, frequency and flow processes and 2) study the nature of continental margin sedimentation during both glacial- and non-glacial periods in the relatively unknown northern part of the Porcupine Bank.

CE10006 2010 Mackerel Egg survey

Every three years the International Council for the Exploration of the Sea (ICES) coordinates a series of mackerel, Scomber scombrus, and horse mackerel, Trachurus trachurus, egg surveys covering the eastern Atlantic from Gibraltar to the north coast of Scotland between January and July. The aim of this survey programme is to estimate the spawning stock biomass of the northeastern Atlantic mackerel and horse mackerel stock. The Marine Institute participates in this programme and in this survey covered stations in the Celtic Sea.     The survey, carried out in March 2010, took place in the Celtic Sea and Southwest of Ireland, from 48.75N to 51.75N, and from 6W to 17W. This covered ICES areas VIIg, VIIh, VIIj and VIIk. For operational reasons the survey was split in two. Leg 1 was conducted on board the Celtic Explorer from March 5th to 17th. This leg targeted the southern transects of the sampling area, and also carried out all the fishing tows. Leg 2 was carried out on the Celtic Voyager from March 19th to 29th and concentrated on the two northern transects of the area. At each station the GULF VII plankton sampler was towed. Fishing hauls were made using a herring pelagic net. The survey aims to collect egg and fecundity data for mackerel and horse mackerel for use in the 2010 stock assessments.

CE10004 Species at the margins - diversity cruise

Box coring, multicoring, vertical plankton tows and CTD casts and ROV ops during daytime during marine research cruise on board Celtic Explorer. (1)	To identify and map benthic macrofauna in slope and canyon regions using conventional cores and ROV surveys  (2)	To characterize the diversity and functional diversity of the bacterial community (with a focus on water column and sponge symbionts) at different depths.  (3)	To collect material for the preparation of extracts in the MI biodiscovery laboratory and to supply marine structures (sponges) for biomaterials testing.  (4)	To isolate bacteria from the water column and sponges and screen these extracts for bioactivity. This work will be accompanied by metagenomic screening to better understand the diversity and function of the entire (i.e. non-culturable) bacterial community.    Hydrographic and related oceanographic information will be collected alongside the main aims of the cruise to gain a better understanding of the environment within canyons and on the slope. It is intended that the cruise will act as a catalyst for collating existing material on Irish deep deep-sea biodiversity in addition to making a large contribution to the knowledge of these communities. A formal link has been made with the Census of Marine Life and this will be used to promote the cruise and strengthen networks with the international community.
