CE18015 SEA-SEIS-D (Structure, Evolution And Seismic hazard of the Irish offshore)

This survey, led by Dublin Institute for Advanced Studies (DIAS) (Geophysics section) took place in September/October 2018 on board the RV Celtic Explorer in the North East Atlantic Ocean.     This survey was part of the SEA-SEIS project (Structure, Evolution And Seismicity of the Irish offshore) and will involve the deployment of ocean-bottom-seismometers that will sink and install themselves at the bottom of the seafloor at depths of 1-4 km in the North Atlantic Ocean. These record the tiny vibrations of the Earth caused by seismic waves, generated by earthquakes and by the ocean waves. During the survey a deep sea mooring was deployed, and the M6 weather buoy was also recovered.    The DIAS OBS deployment survey is part of a new project "Structure, evolution and seismic hazard of the Irish offshore," funded by Science Foundation Ireland (SFI), Marine Institute and the Geological Survey Ireland and started on the 1st March, 2018. This survey was carried out to deploy broadband, ocean-bottom seismometers across Ireland’s offshore.

CE18012 Exploiting and conserving deep-sea genetic resources: Science Foundation Ireland (SFI) cruise II

This 12 day survey took place on board the RV Celtic Explorer in August 2018 led National University of Ireland, Galway (NUIG) in the North East Atlantic Ocean. The survey was carried out to collect fauna (specifically sponges and corals) using the ROV. 12 science dives were carried out as well as high definition video data recorded. The wider objectives of the Science Foundation Ireland (SFI) project were to:  (1) target biodiscovery research at cnidarian (coral) and sponge species that occur in Ireland’s offshore waters, via a comprehensive collecting and screening programme.  (2) predict the likelihood of novel products being found in any other sponge or coral species occurring in Irish deep waters, based on the known relationships between species (knowing that secondary metabolite evolution often mirrors taxon evolution) and based on data both generated during the project and already available on potential novel natural products.   (3) analyse the distribution of species with predicted biodiscovery potential to provide maps of ‘biodiscovery hotspots’ which will allow more cost efficient future exploitation and also provide information that will facilitate their effective conservation.

SmartBay Observatory Fluorometer Data (Processed)

The SmartBay Observatory in Galway Bay is an important contribution by Ireland to the growing global network of real-time data capture systems deployed within the ocean. Installed on the seafloor 1.5km off the coast of Spiddal, the observatory uses cameras, probes and sensors to permit continuous and remote live underwater monitoring. Data relating to the marine environment at the site is transferred in real-time from the SmartBay Observatory through a fibre optic telecommunications cable to the Marine Institute headquarters and then made publicly available on the internet.

A WetLabs ECO-FLNTU fluorometer is installed on the observatory infrastructure. It measures the fluorescence of the seawater to give an estimate of the volume of chlorophyll present (indicative of the amount of phytoplankton in the seawater) and it measures turbidity, or the ‘cloudiness’ of the seawater, caused by the presence of particles such as sediment from the seabed suspended in the water. 

This dataset comprises of measurements taken from the fluorometer, including the concentration of chlorophyll and the turbidity of the seawater.

North East Atlantic ROMS Hydrodynamic Model

The ROMS (Regional Ocean Modeling System) hydrodynamic model is run for a domain that covers the Irish waters in the northeast Atlantic. The model has a mean horizontal resolution of 1.9 km and 40 terrain-following vertical layers. The system produces a best estimate of the ocean state once a week and also a daily 3-day forecast.    Parameters modeled include: ocean temperature and salinity, sea level, and ocean currents.    In addition, two models with a horizontal resolution of 200 - 250m are nested within the larger model to give 3 day forecasts of ocean state for the greater Galway Bay area (Connemara model) and the southwest of Ireland (Bantry Bay model).    The ocean forecasts are generated on a 'best endeavors' basis and should not be used for safety critical applications. 7-day forecasts are generated for research purposes and for comparison with measured data. NCEP GFS atmospheric forcing is used and the model is nested within the MERCATOR North Atlantic model. The Marine Institute does not guarantee to make model output available on its web site.

Measurement of Seawater Temperature at Carna, Co. Galway (1974-2003)

Sea water temperature was monitored on a continuous basis from the start-up of the laboratory at Carna (Co. Galway) in July 1974 until 2003, when a rebuild of a section of the laboratory removed the recorder.    The sea water intake pipe extended about 100m beyond the end of the pier, the pipe running in gullies between the rocks, weighed down with concrete weights to a point beyond the low water springs mark. It was 4inch Hydrodare  pipe, pinned along the outside of the pier wall, to the lab, where it entered the building through a constant head arrangement of the pipework. The total distance from intake to the lab was about 200m. A pump house was built on the seaward side of the pier. The pumps were centrifugal patterns, and the pumps were change dover the years as larger volumes were required. The minimum flow rate was 600L per minute. This flow would increase slightly on a high tide. After installation, for a period of about three months, the displayed temperature was checked against the temperature at the tide edge and no discernible difference was noted. Pipe intake at approx. 53° 18.55'N, 9° 49.75'W.    The measurement device was initially a Cambridge Instruments 10 inch circular chart recorder fitted with a seven day rotation motor. The first measurement system was a MIS expansion probe, connected to the recorder by a capillary, the actual measuring bulb was contained in a stainless steel pocket fitted into the incoming seawater line.    On changing the chart, the temperatures were extracted by hand and then typed up. The temperatures were taken for midnight, 6am, noon and 6pm. Where the clocks went forward in Spring for Summer Time or back in Autumn to GMT, the changeover on the chart would usually have been on the following Monday morning about 9am.    When the recorder pattern became outdated around 1998, and spares difficult to obtain, the recorder was changed for a Cambridge Instrument P100L, 4 inch strip chart recorder. The measuring probe was a Pt100 platinum resistance thermometer, BS1904 specification, again fitted into a stainless steel pocket fitted into the supply line. The charts on this instrument were changed on a fortnightly basis and again, the six-hourly temperatures extracted by hand and typed up. Recording of sea water temperature on a continuous basis (four recordings daily) from the start-up of the laboratory at Carna (Co. Galway) in July 1974 until 2003.

Midnight surface water temperatures from the Mill Race, Furnace, Newport, Co. Mayo

The Mill Race links upstream Lough Feeagh with Downstream Lough Furnace. The channel is short (200 metres) and shallow (<1 metre generally) and water temperatures measured here are very close to those measured on the surface waters of Lough Feeagh. This record has therefore, historically been used as a proxy for Lough Feeagh surface water temperature. Between 1960-2004, a Negretti paper chart recorder was used, and data were extracted for midnight each day. The chart recorder was checked sporadically against a mercury thermometer. From 2004 to 2009, a StowAway TidbiT temperature data logger from Onset (TBI32-05+37) was used (https://www.onsetcomp.com/products/data-loggers/tbi32-0537 ), and data extracted for time step nearest midnight. Between 2010 and 2017, temperature was recorded using an Orpheus mini water level recorder and data extracted for time step before midnight.

Connemara 3D Oceanographic Model

The Connemara 3D Model provides data for Galway Bay on the oceanographic parameters: Sea Temperature (degreeCelsius), Salinity (Salinity, PSU), Sea Water X Velocity (m/sec) and Sea Water X Velocity (m/sec). The ROMS model uses the sigma vertical coordinate system which is terrain-following (ie. thickness of levels vary with total water depth within the model domain). Thus in the Connemara model the altitude dimension does not refer to depth, but to model level where 1 is the bottom level and 20 is the level at the sea surface. Level 10/11 is approximately mid water but the other model levels cannot be ascribed to any single depth level. Users of the download service can choose a datetime, parameter(s), altitude range (choose one altitude only for png and geotiff) and output file type. Note that at any one time, model data is available for the previous 30 days and 3 days into the future.
