Today a video of the last cruise of practical work at sea by the students of the Marine Sciences degree and Master in Oceanography. Enjoy the photographs made by Igor Fernández, Melchor González-Dávila (most of the pictures) and Lidia Nieves. To all of them, thank you for sending the slides.
The paper of today is the last one published by Pascal Lehette and Santiago Hernández-León in Limnology and Oceanography: Methods. It is a calibration exercise to obtain biomass of zooplankton from the body area of the organisms. Because now we can photograph, record or scan a zooplankton sample and we can have the area of every organism, the total biomass and the biomass size spectrum can be obtained converting the body area of every organism into biomass using the relationships given by these two researchers. Therefore, there is no need to destroy the sample to know its biomass (as for dry weight). Now, you can preserve the sample for other purposes (taxonomic studies,...).
