A quantitative study of phytoplankton from the equatorial Pacific

The "neutral" community structure of planktonic herbivores, tintinnid ciliates of the microzooplankton, across the SE Tropical Pacific Ocean

“…With the decline of survey campaigns, the zone was very rarely sampled (Hasle, 1959). The few modern research efforts or major programs in the SE Pacific (such as EastroPac in the late 1960's), in common with other oceanic areas, were process studies, focused on parameters such as biomass estimates and rate measures of primary and secondary production.…”

Contribution à l'étude des phytoplanctontes du détroit de Northumberland, Nouveau-Brunswick, Canada

“…-1 avec des filets de 100 .sm de vide de maille derives du 'Juday-Bogorov' (Arnaud & Mazza 1965) et munis de volucompteurs . La fixation du plancton vegetal recueilli a ete faite avec une solution de formol a 2% tamponnee par de 1'acetate de sodium (Hasle 1959) . Les phytoplanctontes ont ete examines au contraste de phase sur microscope inverse suivant la methode de sedimentation (Steemann Nielsen 1933) .…”

Variability of Winter-Spring Bloom Phaeocystis pouchetii Abundance in Massachusetts Bay

“…Subsamples of 800 mL were collected from the appropriate Niskin bottle and preserved with Utermöhl's solution (to 1 %) prepared as described in Guillard (1973). At the laboratory, the seawater samples were prepared for analysis by concentrating the sample by gravitational settling as described by Borkman (1994) which is similar to the methods of Hasle (1959), Iriarte and Fryxell (1995), and Sukhanova (1978). Phytoplankton analyses were performed as described by Hunt et al (2010).…”
