Cocco Catch-Up

Comments Off on Cocco Catch-Up

The next TMS Nannofossil Group ‘Cocco Catch-Up’ will take place on Wednesday 9th June 2021. This will be hosted virtually, starting at 12:30 UTC (13:30 in the UK). We hope that you are able to attend.

This event offers an informal opportunity to present and discuss ongoing work, recent progress and new ideas, without the confines/commitment of producing a formal ‘conference-ready’ talk. These occasions have been highly productive in the past and we hope that it will stimulate some useful discussion within our Nannofossil community. 

Please see the below for more details and get in touch if you would like to attend or present. Zoom login details will be provided at a later date to those who express their interest via email. We look forward to hearing from you!

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

Comments Off on 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

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.

Mariem Saavedra-Pellitero, University of Birmingham

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.

TMS Annual Conference 2021

Comments Off on TMS Annual Conference 2021

We are looking for volunteers to host next year’s Annual Conference! The Annual Conference takes place in November and typically consists of a day of keynote speakers, Society business and the conference dinner (in case of a physical meeting), followed by a day of talks and posters. We hope that by this time next year we will be able to have a physical meeting again, but if the situation requires a (partly) virtual meeting, TMS will be able to assist with setting up a virtual platform. 

As many past meetings have been UK-based, we are now looking for a location outside the UK. If you would like to volunteer to host the meeting in November 2021, please send a short (<5 min) promotion video about your proposed meeting location to events@tmsoc.org. This can be very simple, such as powerpoint slides with recorded audio. Useful information to include are potential venues, possible accommodation options (e.g. affordable options for students) and travel information. Green transport options such as trains are a plus! Deadline for submission is 31 December.

In January all videos will be published through the TMS channels for members to vote on their favourite location. The winning location will be announced by the end of January. If you have any questions please email the Events Secretary Anieke Brombacher (events@tmsoc.org)
