Two Cladonia lichen species, C. stellaris and C. rangiferina are pictured here among some blueberry plants in Newfoundland.  Lichens -- which are often mistaken for moss -- are unusual plant-like organisms that are actually symbioses of fungi, algae and bacteria living together.

Equipped with a multibeam bathymetric system and acoustic Doppler current profiler, the research vessel Lucien Brush was deployed to make comprehensive maps of the potential spawning area.  In order to collect precise location data, a base station is set-up within view of the area to be mapped.  Luckily, a sandbar was still peaking above the river’s surfac
