General Research Area

The Biogeoscience Research Group is concerned with understanding the seabed offshore Ireland and investigating groundwater-seawater interactions in the coastal zone.

Disciplines

geophysics, hydrogeology, sedimentology, oceanography, marine biology and numerical modeling

Group Members

Colin Brown, Rachel Cave, Eve Daly, Garret Duffy, Anthony Grehan, Tiernan Henry, Klaus Leurer, Barbara Petrunic, Martin White and Mike Williams (all from Earth and Ocean Science, NUI Galway)

Brief description of current projects

A. Grehan & C. Brown use remotely operated vehicles, high-resolution multibeam acoustic and optical data to understand seabed properties and, along with ship-borne acoustic data from the INSS and INFOMAR, predict benthic habitats for key species.

E. Daly & C.Brown use advanced interpretation techniques to interpret gravity and magnetic data on the Irish Atlantic margin.

T. Henry, R. Cave, E. Daly, & B. Petrunic are using hydrogeology, geochemistry and geophysics to quantify groundwater-seawater interactions in the coastal karst systems in Co. Galway and Co. Clare.

K. Leurer & C. Brown are concerned with the development of theory and computational tools to interpret the multibeam acoustic backscatter and seismic reflection data acquired by the GSI and Marine Institute in the INSS and INFOMAR.

M. White is acquiring physical oceanographic data that are used, along with high-resolution INSS and INFOMAR bathymetry, to model deep ocean and inshore currents and their effects on ecosystem functioning.

G. Duffy & M. Williams are utilising hydrodynamic modelling, ROV imagery, ground-truthing, multibeam bathymetry and backscatter to understand the past and present sedimentary processes in Galway Bay.
