South Rockall Trough Sub-surface Mooring Time-Series (October 2018 - current) - CTD Data (Raw)

This dataset contains raw water temperature, conductivity (derived salinity) and pressure data from CTD instruments from a succession of deep water moorings deployed at a site (15.52 degrees West, 52.999 degrees North) in the South Rockall Trough close to the M6 met-ocean buoy. The sub-surface moorings consisted of an array of 10 Sea-Bird SBE 37 CTD sensors at a series of fixed depths below the surface (500m, 625m, 750m, 1000m, 1250m, 1500m, 1750m, 2000m, 2500m, 3000m). The CTD sensors were fully calibrated by Sea-Bird in Germany both pre and post deployment. Additional sensors on the mooring include ADCP sensors to measure ocean currents and direction. This datasets combines the measurements from a pilot sub-surface mooring was deployed in October 2018 and retrieved in May 2019 by the Marine Institute and second deployment was made in April 2020 into a broken time-series. At present there are no operational funds to maintain a continuous series of moorings at the South Rockall Trough location but when logistics and infrastructure are available future deployments may take place.

CE18005 Blue Whiting Acoustic Survey - pCO2

pCO2 is the partial pressure of CO2 in a liquid or gas. In oceanography, it is used to investigate carbon dioxide (CO2) dissolved in the surface layers of the ocean in order to better understand changes in ocean carbon chemistry and ocean acidification due to enhanced atmospheric CO2.

The RV Celtic Explorer has a pCO2 Underway System. pC02 data was collected as part of the CE18005 Blue Whiting Acoustic survey on board the RV Celtic Explorer in March/April 2018 by the Marine Institute (MI) in the North East Atlantic Ocean.

Instrument information:
- SST (± 0.05 deg C):
During this cruise the data from the thermosalinograph were not available. Based on 9 cruises in 2018 (spread over the course of the year) where both,
SST and equilibrator temp (Equ_T), were available we established a relation to calculate SST from Equ_T: The data from SST were shifted by 2 minutes to account
for the time the water needs from the intake to the equilibrator. The resulting linear function is SST = 1.01181 * Equ_T - 0.434. By comparing the calculated SST 
with measured SST from cruises that were not used for establishing th erelationship we found the standard deviation of SST-SST_calc was always lower then 0.05°C.


-Equilibrator temp (±0.05 °C):
Equilibrator temperature is measured by a Fluke Hart 1523, wich is known to be stable over a longer period. It was calibrated in 2016.

-SSS (± 0.5 PSU):
SSS was measured with a thermosalinograph from Seabird (SBE21) which was calibrated approximately every 12 months. 

-Atmospheric press. (± 0.1 mbar):
Atmospheric pressure was measured using a Druck barometer with a precision of 0.2%. The sensor is installed at approximately 5m height 
and pressure is corrected to sea level.

-Equilibrator press (± 2 mbar):
The equilibrator is open to the atmosphere. Since no absolute pressure sensor was installed the pressure from the atmospheric pressure sensor was used.
A SETRA difference pressure sensor is attached to the equilibrator.

-pCO2/fCO2 (±3µatm):	
Accuracy of pCO2/fCO2 data was recalculated to be better than 2 µatm.
	IR sensor:		Licor 7000, calibrated with 3 non-zero standard gases.
	Standard gases:		Manufactued - Air Products, Calibrated - Mace Head Research Station (198.29 399.28 606.52])
	Water flow rate: 	2-3 L min-1
	Gas flow rate:		80 - 220 mL min-1 (equilibrator gas flow was 220 mL min-1)

A General Oceanics pCO2 system (model 8050) was used for pCO2 measurements. The system is described in detail in Pierrot et al.(2009). 
Surface water is pumped continuously from the intake to the equilibrator. The equilibrator contains a water spray head, 
and as the water flows through it the dissolved CO2 equilibrates with the headspace. The headspace is dried and xCO2 is determined 
by an infrared sensor. Calculations were performed following Pierrot (2009) and are described in detail in Steinhoff (2010).

Seabed Sediment Classification

Multibeam echosounder data and seabed sampling data acquired during the INFOMAR and INSS national seabed mapping programmes are the primary sources of data used in the generation of this collated seabed classification/marine habitats layer. Lower resolution interpretations of INFOMAR data that were provided to the EMODnet Geology project have been integrated into this layer. Areas where there is no multibeam data have either been filled by EUSeaMap (predictive broadscale habitat map) or have been left as unclassified. The original classes assigned to the data were translated to a modified Folk class to facilitate reclassification of the data to both EUNIS and MSFD Benthic Broad Habitat Type classification systems. Additional information on biological zones from the EMODnet Seabed Habitats project were used to translate the data to EUNIS.

Archaeologically Significant Built Heritage in Ireland

This contains records taken from the Archaeological Survey of Ireland (ASI) dataset, updated in 2018 and published from the National Monuments Service Sites and Monuments Record. The ASI has focused on recording monuments dating from before AD 1700, along with more recent sites selected according to their interest or merit. Locations of monuments within 2km of the coastline were extracted from the ASI dataset by Land Use Consultants (LUC).

The records were downloaded from the data source URL in CSV format. The table included latitude/longitude locations for each record. The table was converted into ESRI shapefile and the records within the 2km coastal zone were extracted.

Since its inception in 1963, the Archaeological Survey of Ireland (ASI) has focused on recording monuments dating from before AD 1700, along with more recent sites selected according to their interest or merit. A Sites and Monuments Record (SMR) was issued for all counties in the State between 1984 and 1992. The SMR is a manual containing a numbered list of all certain and possible monuments accompanied by 6-inch Ordnance Survey maps (at a reduced scale). An Urban Archaeology Survey was completed in 1995 and contained reports on historic towns dating to before AD 1700 with a view to delineating zones of archaeological potential. Both the SMR and the Urban Archaeological Survey reports were issued to all planning authorities. The SMR formed the basis for issuing the Record of Monuments and Places (RMP) - the statutory list of recorded monuments established under Section 12 of the National Monuments (Amendment) Act 1994. The RMP was issued for each county between 1995 and 1998 in a similar format to the existing SMR. However, the RMP differs from the earlier lists in that, as defined in the Act, only monuments with known locations or places where there are believed to be monuments are included. The large archive and supporting database are managed by the National Monuments Service and the records are continually updated and supplemented as additional monuments are discovered.

Please note that the centre point of each record is not indicative of the geographic extent of the monument. The existing point centroids were digitised relative to the OSI 6-inch mapping and the move from this older IG-referenced series to the larger-scale ITM mapping will necessitate revisions. The accuracy of the derived ITM co-ordinates is limited to the OS 6-inch scale and errors may ensue should the user apply the co-ordinates to larger scale maps. Records that do not refer to 'monuments' are designated 'Redundant record' and are retained in the archive as they may relate to features that were once considered to be monuments but which on investigation proved otherwise. Redundant records may also refer to duplicate records or errors in the data structure of the Archaeological Survey of Ireland.

SmartBay Observatory Video Camera Data (Raw)

The SmartBay Observatory in Galway Bay is an underwater observatory which uses cameras, probes and sensors to permit continuous and remote live underwater monitoring. It was installed in 2015 on the seafloor 1.5km off the coast of Spiddal, Co. Galway, Ireland at a depth of 20-25m. Underwater observatories allow ocean researchers unique real-time access to monitor ongoing changes in the marine environment. The Galway Bay Observatory is an important contribution by Ireland to the growing global network of real-time data capture systems deployed in the ocean.

Data relating to the marine environment at the Galway Observatory site is transferred in real-time through a fibre optic telecommunications cable to the Marine Institute headquarters and then made publicly available on the internet. The data includes a live video stream, the depth of the observatory node, the water temperature and salinity, and estimates of the chlorophyll and turbidity levels in the water which give an indication of the volume of phytoplankton and other particles, such as sediment, in the water. Maintenance take place on the observatory every 18 to 24 months. 

Video data is streamed in near-real-time from the observatory and this dataset describes the video footage that is available for download.

Maintenance take place on the observatory every 18 to 24 months. 

A WetLabs ECO-FLNTU 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.

The following paramaters are available:
- Timestamp & Instrument Code
- Date-time (time stamp from a Global Positioning System receiver at the cable observatory shore station in the format YYYY-MM-DDThh:mm:ss.sss)
- Instrument-ID (unique identifier for the instrument based on its manufacturer, model number and serial number)
- Instrument clock date in the format MM/DD/YYYY
- Instrument clock time in the format hh:mm:ss
- Wavelength of light used to make fluorescence measurements in nanometres
- Chlorophyll fluorometer instrument output (counts) (no units)
- Wavelength of light used to make turbidity measurements in nanometres
- Optical scattering turbidity sensor instrument output (counts) (no units)
