Foraminifera (prepared slide of historic material).
Foraminifera (prepared slide of historic material).
From the slide label: "Foraminifera Globigerina Ooze; Challenger Station 338; March 21st 1876; 21Deg-15min S. 14Deg 2min W; 1990 Fathoms; South Atlantic. Ex Norman." Strewn, dry mounted by Brian Darnton.
Slide was illuminated from above the stage by an IKEA LED lamp and a cut table-tennis ball was used as a diffuser [4x objective]. Two areas of the slide are shown below.

Great photos, gekko.
A little geology, a little geography, and a little history. I love the old slides.

Re: Foraminifera (prepared slide of historic material).
spectacular images, really good
Re: Foraminifera (prepared slide of historic material).
I agree with lorez, a good history lesson. Where did you get the slide?
Re: Foraminifera (prepared slide of historic material).
lorez, seb, and Walter: Thank you very much for your kind remarks .
JimT: This is one of a set of four slides of historical material that I bought on eBay some time ago. If I manage to get acceptable images of the others, I'll post them.

Re: Foraminifera (prepared slide of historic material).
Got me looking Foraminifera up on the internet. :)
Then I looked up Challenger Station!

How large would the Foraminifera be?
Thanks for a most interesting thread.

Re: Foraminifera [added another image with scale]
Thank you, 75RR, for your comments and for the very fascinating link! Below is an image of another part of the same slide [4x objective] to which I've added a scale bar to help answer your question about the size of the foraminifera (the same scale applies to the other two images):

Re: Foraminifera (prepared slide of historic material).
Just added another one to my previous post. You have the equivalent of Moon Rocks there!Thank you, 75RR, for your comments and for the very fascinating link!
Thanks for sharing.

Many thanks! Also, if anyone is interested in slide-mounting foraminifera, please Google "Brian Darnton" and you'll find much information.75RR wrote:Just added another one. You have the equivalent of Moon Rocks there!Thank you, 75RR, for your comments and for the very fascinating link!

Re: Foraminifera (prepared slide of historic material).
Wow! This second link that you added:75RR wrote:Just added another one to my previous post.

is super! It gives a succinct explanation of (and feel for) the expedition. And especially the last item, the beautifully illustrated Report, is fantastic! Thank you!!! What one learns on this forum!
Re: Foraminifera (prepared slide of historic material).
Gekko,
excellent images - did you try do stack?
PS.: Last days I was very busy (Christmas holidays ...) but I hope to have time to upload some new pictures next time.
Warmest regards
Manfred

Re: Foraminifera (prepared slide of historic material).
Many thanks, Manfred. No, I did not use a stack, just single images. I hope you had a good Christmas and look forward to seeing more of your photomicrographs .
Re: Foraminifera (prepared slide of historic material).
I thought I'd add a picture of the slide itself:
Re: Foraminifera (prepared slide of historic material).
Good idea. Context is everything.
At a very rough estimate, looking at a wall mounted World Map, I think Station 338 is somewhere off the Skeleton coast.
