| The planktonic haptophyte Phaeocystis has been suggested to play a fundamental role in the global biogeochemical cycling of carbon and sulphur, but little is known about its global biomass distribution. We have collected global microscopy data of the genus Phaeocystis and converted abundance data to carbon biomass using species-specific carbon conversion factors. Microscopic counts of single-celled and colonial Phaeocystis were obtained both through the mining of online databases and by accepting direct submissions (both published and unpublished) from Phaeocystis specialists. We recorded abundance data from a total of 1595 depth- resolved stations sampled between 1955-2009. The quality-controlled dataset includes 5057 counts of individual Phaeocystis... |

| Based on an international workshop (Gothenburg, 14-16 May 2008), this review article aims to combine interdisciplinary knowledge from coastal and open ocean research on iron biogeochemistry. The major scientific findings of the past decade are structured into sections on natural and artificial iron fertilization, iron inputs into coastal and estuarine systems, colloidal iron and organic matter, and biological processes. Potential effects of global climate change, particularly ocean acidification, on iron biogeochemistry are discussed. The findings are synthesized into recommendations for future research areas. |

| The growth of <i>Prorocentrum lima</i>, a toxic algae producing okadaic acid, has been followed in culture media with a variety of organic enrichments obtained from soils and composts of different origins. Two strains were studied and did not respond in the same way to the enrichments. Each strain also responds differently to each type of enrichment. Compost extracts, rich in organic matters, induce faster growth (growth rate 0.07/day) than extracts of soils poor in organic matter (growth rate 0.016/day). Such findings may contribute to explain the mechanisms inducing or triggering bloom developments which occur in neritic and coastal waters where terrigenous run-off mostly influences the organic content of seawater. |
