I've never seen anything like this amount of the stuff before. While it's a novel thing to see, and kind of fun to watch dogs play in, it's disturbing to find that it may be a harbinger of changes afoot in the North Sea and in the global climate. The foam is formed (according to the site below) by a micro-organism called phaeocystis. With excessive nutrients, it blooms out of control and forms large gelatinous blobs. When whipped up by wind and waves, they become sea foam. The blooms also produce a volatile sulphur compound that contributes to climate change. europa.eu.int/comm/research/rtdinfsup/en/world4.htm.

Emiliania (emil-ee-ann-ee-a) huxleyi, a coccolithophorid haptophyte. It can exist in several different forms, and these are the non-motile coccospheres, in which the cells, with golden plastids, are enclosed in layers of small calcareous scales. Differential interference microscopy. " data on this strain.

SEM of coccosphere - E. huxleyi type A

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.

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

Broken coccolith of H. wallichii in distal view, breakage shows the proximal shield.

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 “normal” 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).
