Abstract

Recent measurements of benthic currents, within the depth range where the highest abundance of the hexactinellid sponge Pheronema carpenteri are found, have been made and compared to historical data for the northern Porcupine Sea Bight region where no Pheronema have been recorded. Bottom currents at a location where Pheronema have not been recorded are much higher than a location where the sponges have previously been sampled. The measurements provide some evidence to support the hypothesis that the sponges favour a location adjacent to regions where enhanced bottom tidal currents are found, but currents experienced by the sponges themselves are much reduced.
