Our upwelling station at Georges Bank was thick with fog; this challenged the ship's crew who followed the drogue drifter (above, middle) for 36 hours (great job!). The water color at this station was much greener than at the "Open Ocean Station": Can you guess why?
The upwelling station's net tow yielded a highly diverse, downright "soupy," assemblage. Chain diatoms, probably Guinardia, dominated the sample.
One type of chain diatom was "curly" in form (above). Another notable diatom was Coscinodiscus, which is shaped like a hockey puck (see below).
The dinoflagellates most commonly seen in the upwelling station net tows were Ceratium. At left (above), is a unusual paired example. The "bow-shaped" organism at upper left is another species of Ceratium. Veliger, "blob-like" larval bivalves, were also captured (above, middle).
Radiolaria (<<) are amoebae that commonly found with phytoplankton. Above are two examples of Copepods that graze on phytoplankton. The Copepod at right is an egg-bearing female.
A relatively large jelly is shown above (at left). A closer view of its mouth and tentacles show its size relative to nearby phytoplankton. Another grazer, an Arrow worm, was found at the upwelling station.
