Spatio-temporal distribution and abundance of Euphausia crystallorophias in Terra Nova Bay (Ross Sea, Antarctica) during austral summer
Average abundance values for Euphausia crystallorophias in the shelf region of Terra Nova Bay were generally high. Mean number of adults and juveniles were 20 and 87 ind/m2, respectively, while larval concentrations were much higher, reaching a mean of 14,764 ind/m2. Euphausia crystallorophias were...
