Nannotax - forum

So, the idea here is that we can use the commenting tools to discuss anything about the site or coccolithophores. If discussions get long we can split the page into different topics. If no-one says anything we may quietly remove the page.

However, we will read every comment posted here so feel free to use this for:

How to add comments

If you scroll down to the bottom of the page you will find a heading "Add Comment" and a form to fill in. To reply to a comment click the curvedarrow symbol below and to the right of it. The same layout is there on every taxon page. For a bit more advice you can see the guidelines.

Dear Prof. J.Young

I will conduct a study on the Paleoclimate Quaternary (Pleistocene-Holocene) Glacial-Interglacial at North East Java Basin, Indonesia.

But I am still confused. Is Climate Change at Quarternary can be recorded on the development and variation Nannoplankton Species?

What Nannoplankton species can be used for the cold Climate founders especially that developed in the Quaternary Period.

That is all and thank you

This site is not really the place for this type of question - the coccoliths listserver would be a better choice. However, this is not a straightforward question. Nannofossils evolved fast in the Quaternary and as a result they are not as easy to use for paleoceanography as we might hope. There are exceptions, for instance Florisphaera profunda is an excellent paleoproductivity indicator, but you may not get very strong glacial-interglacial contrasts and should combine your data wiith other proxies.

Hi dear prof. Young

I'd like to know if it's possible to add another option for sorting genera and spices by image based on their lateral view too?

Regards.

Fatemeh -we can't really do that but you can select for basic shape placolith vs murolith vs planolith, for forms with a spine, for high or low rims etc. The system is a bit compplex but if you experiemnt you should be able to do most types of search you want.

what's a difference between the Paleocene Eocene Thermal maximum and Eocene thermal maximum? can we deal both phenomenons as same single process?

Gravatar
Jeremy Young (UK)

Kamran - the Paleocene Eocene Thermal Maximum (PETM) is a short interval of elevated paleotemperatures at the Paleocene -Eocene boundary - you can find out much more about it easily with a google search. The term Eocene Thermal Maximum is not conventionally used but the term (Early) Eocene Thermal optimum is used for the extended period of maximum temperatures in the Early Eocene.

Tags, Metrics and Advanced Search - for INA16 in Athens we have launched a major upgrade to the site. All cenozoic taxa have been reviewed and data added in terms of a set of 'tags' for morphological characters and 'metrics' (coccolith and coccosphere size, liths per sphere, elements per lith). This data has been applied systematically and can be used to from the Advanced Search page (Tools Menu) to aid identification. The system is a bit complex so do read the explanatory page (About Nannotax menu).

Revised recent comments page I have just now revised the recent comments page so that it shows replies below the original comments. This should make it easier to see how comments are addressed (and in some cases has resulted in us finding comments we had not answered)

Great! I found this site. Grateful to the Organizers.

I sometimes have difficulty identifying these Nannofossils forms on Light microscope, because some of them looks alike.

Please I also wish to know the BEST method for preparing Nannofossils Slide for enhanced recovery.

Lastly at what temperature should these slides be dried using the Electrical Hotplate.

Regards

Methods - there is a useful overview of methods in Bown (1998) Calcareous nannofossil biostratigraphy. For drying slides it is best to use a fairly low temperature (around 60°C), as you do not want to boil the water.

Best way to enhance recovery? that depends on the sample but the best technique to start with is almost always to do a direct smear (i.e. mix a little sediment in a drop of water on slide and then smear it over the slide with a toothpick). Then having seen what is in the rock you can try experimenting with how to improve recovery - but for most routine work we just use smear slides.

LM identification - they are not always easy, but as you study them you will learn more.

hi my dear friend

please introduce me a reference or definition for sister,daughter and other terms relate them?

Gravatar
Jeremy Young

Kurosh

We are using these terms as indicators of relative taxonomic position. So for example all the species inside a genus can be described as daughter taxa of that genus and they are sisters of each other. The whole database is organised hierarchically so it is quite convenient to use these sort of terms.

hi again prof

And what a bout daughter and granddaughter?

Gravatar
Jeremy Young

Kurosh

Sorry if this is confusing - there is nothing really ver technical about this we are just using the terms to indicate relative position in the classification, as used on the site. So if we consider the family Rhabdospheraecae its daughter taxa are are all the genera within it -Acanthoica, Algirosphara etc. and its granddaughter taxa are all the species within it - Acanthoica acanthifera, Acanthoica acanthos etc.

Update to range plots - I have now changed the way range data is plotted on species pages, the histograms still show the data from the Neptune database but the nannotax range is now directly compared to it. Also the background image shows the stages using GTS colours (hover mouse over the plot to see stage names).

Hi
Is there any Channel about calcareous nannofossils in telegram or other social networks?

Jeremy Young (UCL, UK)
I don't think so - probably the closest is the INA Facebook pagehttps://www.facebook.com/INA.education"""

Hi,
I am doing a little study sort of updating Aubry et al. 2005 on Mesozoic cocco size. To do so, I saw that we can plot coccolith from nannotax with stratigraphic range. But I wonder we can extract those data in .txt? It would save me thousands of copy/paste.
Thanks

hi Baptiste
If you let me know what you want I can almost certainly send you the data

I would like to know if someone is working with calcareous nannofossils from Eastern Equatorial Pacific, my field work is in this area. I found very few publication on Cenozoic calcareous nannofossils for this area. I am wondering if it is worth to make a review paper for this Pacific side and construct a geographic data using ArcGIS.

Hi Emilia
It might be worth trying posting that on the coccoliths list server, that may work better for getting general comments. Synthesising an reviewing data almost always proves useful in my experience though so your idea sounds well worth thinking about.

hi, thanks for good website.If you have a possibility of sorting all specious of nannofossils based on each stages(age range) for search, it will be more helpfull. Regards.
Gravatar
Jeremy Young (UCL, UK)
Hi Fatemeh
The main way you can do an age related search is to go to Tools/Prefs & Time Control. There you can set the time interval you are interested in (e.g. Oligocene or Albian or 100 to 102 Ma) and the taxa which fall within that time interval will be highlighted. If you wanted something a bit different to that then feel free to explain a bit more.
All the best

Hi
thanks for your reply,I tried in that way but It didn't work or I need more guide. Regards

Hi Fatemeh
- there is more information on the user guide page http://ina.tmsoc.org/Nannotax3/ntax-userguide.html

That should explain what to do.

Hi. I'm a usual user of Nannotax. I was only wondering if it's goin to be available in the future a sort of "mobile application"of the website in order to make the most of it also on mobile devices.

Thanks and good nannopaleontology to anyone !

A few more recent updates:

  • Farinacci catalog pages are now all available as PDFs with selectable text
  • Image file names can now be shown below the images (see Tools/Prefs & Time Control)
  • A lot of extra Mesozoic images have been added
