    Low water mass movement of ocean currents from the Irish Offshore Strategic Environmental Assessment (IOSEA 5) publication. Large masses of moving water are called currents. In the oceans there are major surface currents, subsurface currents, and tidal currents. This data is a...

    Multibeam echosounder data and seabed sampling data acquired during the INFOMAR national seabed mapping programme were the primary sources of data used in the generation of this habitat map for the Inshore Fisheries section of Bord Iascaigh Mhara. The original sediment classes...

    An ocean current is a continuous, directed movement of seawater generated by forces acting upon this mean flow, such as breaking waves, wind, the Coriolis effect, cabbeling, and temperature and salinity differences, while tides are caused by the gravitational pull of the Sun...

    The Biologically Sensitive Area sets out the criteria and procedures for a system relating to the management of fishing effort in waters around Ireland that are considered biologically sensitive. A specific effort regime shall apply to the area enclosed by the coast of...

    A tidal atlas or a tidal stream atlas is used to predict the direction and speed of tidal currents. A tidal atlas usually consists of a set of 12 or 13 diagrams, one for each hour of the tidal cycle, for a coastal region. Each diagram uses arrows to indicate the direction of...

    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...

    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...

    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...

    In oceanography, a front is a boundary between two distinct water masses. The water masses are defined by moving in different directions, i.e. on one side of the front the water is generally moving in one way, and on the other side of the front, the water is moving in another....
