Southern Ocean Diatoms

| Welcome This website is dedicated to Southern Ocean diatoms, with special attention to the species I encounter in my own studies of ocean sediment material from the South Atlantic Sector of the Southern Ocean. The pages are still under construction, so bear over with the many blank pages or half-finished jobs. I will get around to it. If you just cannot wait or have suggestions to improve these pages, by all means mail me and I will look into it when I get around to it. Structure of the website The focus of the website is on the descriptions of the diatoms encountered in my samples from the Southern Ocean, as mentioned previously. Everything else revolves around that, for now. The menus at the top of each page will bring you to any of the main pages in this website, while the menu on the left site is designed to make it easy to navigate the diatom species descriptions.
News 24.05.2002 At last I had time to look at the pages again. Some description of species have been fleshed out a bit, and a few severely underdeveloped descriptions of new genii and species have been added. News 20.09.2001 Species added this time includes Membraneis imposter, M. challengeri, another Thalassionema nitzschioides variant - here called longitissima, Asteromphalus hyalinus - included a 5-armed variety!, Corethron cryophilum, Rhizosolenia antennata var. antennata, and Rhizosolenia polydactyla got its picture taken finally. News 04.08.2001 After a time of absence, it is back to work. New species have been added, Actinocyclus ingens, A. actinochilus, Coscinodiscus oculus-iridis (a very small specimen), Fragilariopsis doliolus, Nitzschia siculata - all very rare species in my samples. A new mystery diatom has been added to those pages. News 15.06.2001 More new species, in the Fragilariopsis, Navicula and Rhizosolenia genera. The new mystery diatom is close to be declared part of a sponge instead. Else, a lot of the illustrations have been added to or improved, as better specimens have been found or better framegrabs have been taken. News 06.06.2001 Quite a few new diatom species have been added to the species descriptions. Now the diatoms consist of both specimens from both Holocene and Late Pleistocene samples, and from both basins in the South Atlantic. The new species are mostly from the genus Thalassiosira, but some interesting Nitzschia and Fragilariopsis species have been added. Another mystery diatom has joined the first one, which is close to be declared whale food and forgotten. -Simon Last edited 24.05.2002 14:46 |
