This image was made from samples taken during a scientific cruise in the Pacific. Water was filtered to concentrate the organisms that were present, then dried onto a thin sheet of plastic and then shadowed with a fine layer of metal to provide contrast. The preparation was then observed with an electron-microscope. This technique has been used to document the diversity of marine microbes, especially, protists in the oceans.

Rhipidodendron (rip-ee-doe-dend-ron, is a colonial spongomonad flagellate, in which the cells are located at the end of a branching (aborescent) colony. The matrix of the colony is formed from adhering small globules of mucilage. The branches are flat, with several channels in each blade. One cell is located at the end of each channel (many of the cells were dislodged from this preparation). Phase contrast.

Chrysochromulina (cry-so-crumb-you-line-a) ericina a single-celled haptophyte, with two similar flagella, long anterior haptonema and a golden colour from two yellow-brown chloroplasts. Small scales lie on the surface of the cell but these are not evident in this image. Phase contrast microscopy.

According to Jeremy Young, this is a fragment of a coccosphere of Umbilicosphaera sibogae.

Helicosphaera wallichii (Lohmann 1902) Okada & McIntyre 1977 [Coccolithophora] Like H. carteri but: central-area with oblique twisted slits; bridge typically better developed; and liths perhaps slightly larger. NB Slits obliquity: In distal view the slits are rotated about 10-20° clockwise (and so away from the wing), this is the ânormalâ sense of obliquity in Helicosphaera, as shown by many fossil species. The Pleistocene species H. inversa is similar but shows the opposite sense of obliquity. HOL phase - unknown but H. wallichii often co-occurs with Syracolithus dalmaticus in our samples (Geisen et al., 2004).

This tiny prymnesiomonad belongs to group of Coccolithophoraceae. In a mucous cover they wear lots of calcified scales (coccoliths). The depth of focus picture shows coccoliths covering the monad cell. Picture generated from 7 shots using CombineZ by Alan Hadley. For details see ZIP archive. Collected from littoral region (stand of Phragmites) of a rain storage reservoir in Kiel (Schleswig-Holstein, Germany). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.

This image was made from samples taken during a scientific cruise in the Pacific. Water was filtered to concentrate the organisms that were present, then dried onto a thin sheet of plastic and then shadowed with a fine layer of metal to provide contrast. The preparation was then observed with an electron-microscope. This technique has been used to document the diversity of marine microbes, especially, protists in the oceans.
