The IMAGIN study has concluded that a number of areas with potential to support marine aggregate extraction exist within the Irish Sea and that marine aggregates can contribute to the sustainable management of demand and future use of aggregates in Ireland.
Multibeam echosounder data and seabed sampling data acquired during the INFOMAR and INSS national seabed mapping programmes were the primary sources of data used in the generation of this Collated Seabed Substrate layer. The original classes assigned to the data were translated to a modified Folk class to facilitate a …
Sea surface temperature is collected via permanent scientific equipment on board the MI research vessel RV Lough Beltra. Data includes temperature from the hull mounted sensor known as 'Hull Sea Temperature' and temperature/salinity from the temperature sensor known as 'Windmill Sea Temperature'. Data collection from the instrumentation is on a …
CTD or Conductivity Temperature Depth stations measure temperature, conductivity and depth of the water column at various depths from the surface to within 10m of the seafloor. A CTD is the oceanographic instrument used to determine the conductivity, temperature, and depth of the ocean. The CTD may be incorporated into …
The diadromous fish census is based on the permanent fish traps at the Salmon Leap and Mill Race in the Burrishoole catchment Newport Co. Mayo. The following parameters are measured: Wild Spring Fish quantity and comments, Wild Grilse quantity and comments, Wild Previous Spawned Grilse quantity and comments, Reared Spring …
The Real Map of Ireland represents Ireland's marine territory of over 220 million acres which is ten times the size of the island of Ireland. The currently designated Irish Continental Shelf, represented by the red line on the map. shows Ireland's current territorial waters which extends out across the North …
The data indicates the location of net fishing activity in Irish waters. Attributes when known include year, area, gear type, species, season, days per year (Days_Year), number of vessels (Vessels), vessel size (LOA_Max), gear units, classification, Area of polygon (Area_M2), and data type. This dataset was created in support of …
Acoustic surveys have been generally carried out on spawning and pre-spawning aggregations of fish. Outside of the spawning season many pelagic species have been generally very scattered over a large geographical area and difficult to detect using acoustic methods. A cruise track was first formulated with data from previous surveys, …
