Photographs, biomasses, morphological parameters and activity states of Primnoella chilensis colonies used in an experiment for sediment exposure of 15 days ...
Colonies of P. chilensis were sampled via self-contained underwater breathing apparatus (SCUBA) diving on 14th and 15th of May 2019 at two different sites in Comau fjord. At each site, 20 colonies of a length between 20 cm and 30 cm were collected at a depth between 16 m and 20 m by cutting the term...
