NannoTalks Volume 2

Comments Off on NannoTalks Volume 2

The International Nannoplankton Association (INA) is happy to announce NannoTalks Volume 2, starting Monday 19th April at 15:00 UTC. Tune in to our transmission on YouTube:

Our first talk will be the Role of silicon in the development of complex crystal shapes in coccolithophores by Gerald Langer. The development of calcification by the coccolithophores had a profound impact on ocean carbon cycling, but the evolutionary steps leading to the formation of these complex biomineralized structures are not clear. Advanced microscopic studies help to understand how these tiny microorganisms calcify and how some coccolithophore species recruit silicon for crystal morphogenesis.

Microfossil Image Competition 2021

Diatoms are tiny, silica-shelled phytoplankton. Not only are they an important part of marine ecosystems and useful tools for studying past climate – this Asteromphalus flabellatus proves that they are also amazingly beautiful!

The Micropalaeontological Society is delighted to announce the winner of the 2020 Micropalaeontology Image Competition!

The overall image winner was submitted by Isabel Dove from the University of Rhode Island – Graduate School of Oceanography, with a beautiful image of the diatom species Asteromphalus flabellatus. Not only does Isabel win the competition’s first prize of €200, but her image is also included on the front cover of our TMSoc2021 Calendar (note these are now sold out)!

On behalf of the Society we would like to congratulate Isabel on her success. Eleven additional winners were selected from the fantastic submissions, and are on display below! A wide variety of microfossils and imaging techniques have been championed this year, and we are already looking forward to next year’s competition.

Additional winners

Odysseas Archontikis and Jeremy Young, University of Oxford and University College London

Coccolith ultrastructure of Cyclicargolithus floridanus. Each coccolith is composed of two interconnecting cycles of the same crystal units, known as the R-units. Coccosphere specimen is c. 10μm in diameter and was collected from Early Miocene dark sapropelic sediments.

Seed of mountain chickweed, Cerastium cerastoides. This creeping arctic-alpine plant bears large white chickweed flowers, characteristic of its family, Caryophyllaceae. It grows in seepage zones from melting snowbeds usually in open gravel or stones. The bean-shaped seeds, about 1.5 mm long, have an amazing pattern of humpy interlocking cells.
Seed of sea campion, Silene maritima. The grey-leaved plants form loose mats and bear large white flowers typical of its family, Caryophyllaceae. It inhabits sea-cliffs, seaside walls, shingle banks, and drift-lines on seashores. Its bean-shaped seeds, about 2 mm long, have an amazing pattern of interlocking jig-saw cells

Look, which surprise: a baby-like Radiolaria in the belly of its mother

Slice through shell of an ancient foraminiferan Rauserella erratica. Image shows the discoidal shape of the early shell which results from regular coiling in a single plane. In later stages, the shell becomes uncoiled as the axis of coiling shift. Shells collected from reef-associated habitats in Permian-aged rocks of North America.

During COVID-19 lockdown, I experienced a great personal tragedy. I drew these two coccospheres of Emiliania huxleyi (type A and type O) to cheer myself up. I hope this watercolor will bring a smile to others.

Nicolai Schleinkofer, Goethe University, Frankfurt

First circular for INA18

Comments Off on First circular for INA18

The 18th International Nannoplankton Association Meeting will be held at the Palais des Papes Conference Centre, Avignon, France between 29th August and 2th September 2021. We hope that everyone will be able to travel safely a year from now, and we are looking forward to a large turnout from the entire calcareous nannoplankton community, especially from those within Europe.

As is the tradition, we plan to organize a 1-day fieldtrip on the Sunday 29th August (followed by the Icebreaker Party), and a 2-day fieldtrip after the conference (3-4th September). Both will be in the Provence-Alpes-Cote d’Azur Region.

In the autumn, there will be a call for session and workshop proposals, so please start thinking about anything you are interested in proposing. Further information can be found at the conference website: https://ina18.sciencesconf.org/, which we will update as the conference dates approach with registration details etc. We expect to open early-bird registration in early 2021.

We look forward to hosting you in Avignon,
Sincerely,
The INA18 organisers: L. Beaufort, C. Bolton & B. Suchéras-Marx
