Plankton Log - MedFlux III Cruise (S. Fowler)

N.B. This describes the principal phytoplankton and zooplankton which were collected as samples. It is not a comprehensive quantitative or qualitative listing of all species present in the water column, just the key species observed or used for analyses.
9 April 2006

Omari Zooplankton net:
Net had huge clumps of green phytoplankton along with the zooplankton. Copepods (Euchirella rostrata, Calanus helgolandicus), salps (Iasis zonaria, Salpa fusiformis, Thalia democratica), euphausiids (Meganyctiphanes norvegica), Euphausia krohnii, and many furcilia stage), psuedothecosome pteropod (Cymbulia peroni), euthecosome pteropods (Euclio pyramidata, Cavolinia gibbosa), and in the green phyto wash there were numerous diatoms (Nitzschia sp. and Thalassionema nitzschiodes).
10 April 2006

Omari zooplankton net:
Lots of jellyfish (Solmissus albescens), psuedothecosome pteropod (Cymbulia peroni), euthecosome pteropods (Euclio pyramidata, Cavolinia gibbosa), copepods (Euchirella rostrata, Calanus helgolandicus), euphausiids (Nematoscelis megalops, Meganyctiphanes norvegica). Also some nektonic shrimp Sergestes
11 April 2006

Took a huge phytoplankton tow that split the net. Nice rich green sample which appeared to be nearly pure diatoms. The main species observed were Thalassionema nitzsciodes, Thalassiothrix frauenfeldi, Ditylum brightwelli, Chaetoceros atlanticum, and what seemed to be was Skeletonema costatum.
12 April 2006

Omari zooplankton net:
copepods (Euchirella rostrata, Calanus helgolandicus), psuedothecosome pteropod (Cymbulia peroni), salps (Salpa fusiformis).
