Nature, 1953
ATKINS1, in 1945, reported on the productivity of the English Channel as estimated by two independent methods. The silicate turnover indicated a far lower productivity than did the phosphate turnover, and from this he deduced that only a relatively small fraction of the phytoplankton could consist of forms with siliceous skeletons.

Notes for a Short Course: Studies in Geology, 1987
Calcareous nannoplankton are minute plant-like protists that live in the marine photic zone. There has been an exponential increase in nannoplankton studies in the last two decades, largely owing to the recognition of the usefulness of this group for biostratigraphic and paleoenvironmental interpretations.

Late Maastrichtian Nannoplankton Provinces
Nature, 1970IT has been known for some time that there was a sharp differentiation of late Maastrichtian faunal provinces with respect to planktonic foraminifera. Axelrod1 has presented evidence that this was also the case with some terrestrial megaphyta, for he found a rather abrupt southward shift for the coniferous vegetation of the northern hemisphere during ...

Taxon lists for studies of modern nannoplankton
Marine Micropaleontology, 2000Six studies in this special issue dealt with modern nannoplankton assemblages. In total during these studies 552 samples were analysed and about 180,000 specimens identified, from 152 species. This paper provides a unified list of taxa from these studies, records the presence/absence of each species across the studies and indicates the more common ...

Annotated index and bibliography of the calcareous nannoplankton V
Phycologia, 1966Abstract This annotated index of 581 entries includes modern and fossil calcareous nannoplankton taxa of all levels, in addition to those appearing in the earlier index and supplements. Some 320 are new entries, 198 of which are valid and 122 invalid.

A Preparation Technique for Calcareous Nannoplankton
Micropaleontology, 1963"Calcareous nannoplankton may be extracted and concentrated by 'short centrifuging'. A method of mounting the specimens on slides is described."

Calcareous Nannoplankton from the Tertiary of Alabama
Micropaleontology, 1967Three biostratigraphic units are recognized on the basis of the vertical distribution of coccolithophorids and related calcareous nannofossils from the Upper Eocene, Lower Oligocene and Middle Oligocene of exposures at Little Stave Creek and St. Stephens Quarry, Alabama.

Critical events in the evolutionary history of calcareous Nannoplankton
Historical Biology, 1991Calcareous nannofossil diversity, and rates of speciation and extinction are calculated for five million year intervals from their first appearance in the Late Triassic through to the Present Day. Important evolutionary events are as follows: first appearance in the Late Triassic, Triassic-Jurassic boundary extinctions, Tithonian radiation (and the ...
