Meeting Microscopic Marvels

Aron O'Shea, 28 August 2024

I’m currently studying heritage conservation at Cardiff University, so I wanted to undertake his placement as I have a keen interest in how museums digitise their collections for educational purposes and to increase the accessibility of the heritage they safeguard, and I also wanted to explore how museum collections are used for research purposes.

What are diatoms?

Diatoms are microscopic, single-celled algae that inhabit oceans, rivers, and lakes. They are notable for their intricate cell walls made of silica, which resemble delicate glass shells when viewed under a microscope. These cell walls, called frustules, have unique and complex patterns. Diatoms play a vital role in the environment by performing approximately one-fifth of the total global photosynthesis. This process not only produces a significant portion of the Earth's oxygen but diatoms also form an important part of aquatic food webs, supporting a diverse range of marine and freshwater organisms.

Their importance for research lies in their ability to act as bio-indicators in aquatic ecosystems. Analysis of diatom populations and diversity studies have been used to evaluate human impact on freshwater and marine environments. As bio-indicators, diatoms can be used to assess the levels of organic pollution, eutrophication and acidification of their aquatic environment. Different species have differing tolerance levels of environmental conditions like water pH (the acidity or alkalinity of the water) and nutrient concentrations. Several diatom indices have been developed and are used by the Environment Agency to monitor water quality in UK rivers and lakes.

Analysis of diatom populations can also be used to demonstrate trends over time, as Ingrid’s work on the restoration of water quality of the rivers Wye and Irfon through periodic liming shows (for more details visit https://www.sciencedirect.com/science/article/pii/S1470160X20309961#ab010). The same case can be made for historical collections stored in museums, which can provide unique insight into historical diatom populations, and which can be used to infer previous environmental conditions and compare them to those found in contemporary studies.

In addition to their environmental and research importance, diatoms are incredibly beautiful. So much so, that during the Victorian period, they were often assembled into decorative arrangements on microscope slides. For the uninitiated, I would highly recommend searching for images of Johann Diedrich Möller’s work as well as the more contemporary works of Klaus Kemp; they are truly astounding arrangements. 

The Placement

Under Dr. Ingrid Juttner’s excellent guidance I learned basic diatom morphology and how to identify Gomphonema species, which typically display asymmetry along the trans-apical axis (i.e. the top and bottom halves are not usually mirror images of each other).

Ingrid took me through the process of diatom analysis in light microscopy, from “cooking” the water samples with hydrogen peroxide to remove organic cell content and preparing the microscope slides, through to photographing, editing and uploading the images to the museum’s diatom website. The photographs featured were taken with a light microscope at x1000 magnification, and measurements (length, width, striae density) were recorded. These images were then edited and prepared as plates to provide an overview of the cell size distribution in the species population. The plates were uploaded to the website with corresponding literature and morphological descriptions. 

Some notable species I photographed which are now featured on the website are Eunotia arcubusEunotia botuliformis and Planothidium incuriatum.

Overall, my placement within the Lower Plants section has

  • Provided me with invaluable insights into scientific and particularly, taxonomic, practices
  • Highlighted the role that diatoms play in our natural environments
  • Demonstrated how museum collections can and are being utilised for the benefit of science as well as being important repositories for mapping changes in biodiversity.
  • Illustrated how projects like the Diatom Flora and Fauna of Britain and Ireland can help create accessible resources for professional and amateur researchers as well as opening up collections to a wider public, who might otherwise be unaware of their existence.
  • Finally, this placement has been an opportunity to admire the exceptional beauty of diatoms.

If you would like to know more about the diatom collection at the National Museum of Wales, please see the museum’s Diatom Research page  as well as  blog posts by Ingrid entitled ‘Scientific expedition to Rara Lake, Nepal’ and ‘Diatom diversity of the Falklands Islands’. I would also highly encourage anyone interested in diatom identification to view the Diatom Flora and Fauna of Britain and Ireland website.

My heartfelt thanks go out to Dr. Ingrid Jüttner for her instruction, her wealth of knowledge and, not least, her conversation. I would equally like to thank the various staff members who coordinated and supported this placement at Amgueddfa Cymru, may there be many more such opportunities.

Work Experience at the National Roman Legion Museum.

Lois Davidson, 17 July 2024

Zoe and I completed a work experience week with the Museum. This is my diary of the week. 

Day 1: 

To begin the week, Zoe and I were able to work with Verdun, the Learning Officer, and shadow him whilst he took a primary school class on what the museum calls a ‘Walk with the Romans’, around the Amphitheatre and Barracks. It was clear to me throughout this experience that the children were gaining interest in the presence of Romans in Welsh history, whilst being given the opportunity to dress up in Roman tunics, with shields and wooden swords, and impersonate soldiers charging into battle. The sheer sense of enjoyment from not only the children, but the teachers as well, was clear to me, which I purely believe was a result of the massive amount of enthusiasm and obvious passion for their work shown by the staff involved in providing this experience. By the end of Day 1, I could safely say that I had gained more knowledge of the Romans impact on Welsh history than I ever had in my 17 years of living, along with the ability to understand how to engage with a large audience and maintain their full attention for a long duration of time.

Day 2: 

As my desired career involves marketing, I was given the opportunity to work with Kathryn, the Digital Learning Officer and understand how she advertises the different workshops, events, and exhibits the museum hosts through its website and social media. To begin, Kathryn talked us through the different apps that are used to create digital content to advertise the museum. I was able to create a twitter post for the museum’s twitter account in order to advertise their ‘Roman Classroom’, which is an online teaching platform that involves a ‘costumed facilitator’ explaining all different areas of Roman history. I thoroughly enjoyed learning about the different methods that are used in order to advertise and market the Museum online, and encourage more to get involved, and immerse themselves in the Roman history that exists in Wales.

Day 3:

For day 3, we spent the day shadowing Dai, Visitor Experience Supervisor. He talked us through what is required of us in order to ensure that visitors are provided with the best experience possible. I was surprised by the sheer number of visitors the museum has every day, whether it is families, school trips, or tourists, whilst also picking up the knowledge of how to supervise and maintain order within the museum.  

Day 4: 

We spent the day with Mark, Senior Curator of Roman Archaeology. We were given the opportunity to photograph artifacts in order to update the museum’s records and provide photos for the website so people can study online.  As well as using the advanced set up to photograph the artifacts, Mark also trusted us enough to handle the objects like a Roman brooch, lioness ornament, and a tile antefix, which was an especially interesting new experience. Along with this I was able to gain knowledge of the stories behind the different artifacts and what they symbolize at the time. After recording the descriptions, accession numbers, and other important information, Zoe and I were able to record that we were the ones that photographed the artifacts, which will then be uploaded for anyone to see.

Day 5: 

I was able to spent some time with Rosie, Commercial Marketing Officer and she gave me amazing advice on steps I can take in order to achieve my career in marketing. As a result, I have gained a contact in the industry I aspire to become a part of, and this is something I would never have been able to attain if it weren't for this work experience, and for that I am eternally grateful.

Lastly, I would like to express how much I appreciate all the opportunities and experiences this museum has provided me with and how much it will benefit me going forward, and Michelle, Engagement & Volunteer Coordinator, who has been a big factor of my experience here, continuing to welcome Zoe and I every morning and seeing us out every afternoon, and ensuring we are given as many amazing experiences as possible. 

I’ve also been inspired to volunteer – and I now volunteer at my local National Trust Property. 

Skills Development Placement at St Fagans

Chloe Ward, 13 December 2023

Harri recently finished a Skills Development Placement at St Fagans National Museum of History, where he shadowed our Front of House staff one day week for 6 months. The placements offer workplace experience for people 16+ who have barriers to work, allowing them an opportunity to build skills and confidence. In St Fagans, we specifically support individuals who are bilingual and Welsh speaking for front of house skills development placement roles.

Before Harri finished, we caught him for a chat to see what it was like taking part in a skills development placement at St Fagans! Here’s what he said: 

 

How did you get involved in a Skills Development Placement with us at Amgueddfa Cymru? 

I started in September 2022. I helped out with the Food Festival at St Fagans and Lauren from Elite Employment Support put me in touch with the Volunteering & Placements department. I met with the team at St Fagans. I am bilingual and it’s an added bonus that I could use my Welsh whilst on placement. 

 

What did you do whilst on placement? 

I started in the galleries for 2 hours. I felt the need to extend my hours to 10.00-3.00, which was just right. 

Whilst on the galleries I helped the Museum Assistants by using the clicker to count people’s attendance. 

Sometimes I would help Will clean any spillages on the galleries. 

I spent a day with Ryland – I remember travelling with him on the buggy to the castle, that was fun! We made sure the garden and the surroundings were tidy. 

 

What did you learn during your time at St Fagans? 

I learned team working skills and learned about the museum itself. Communication with the Museum Assistants. If I was ever unsure what to say to visitors, I would get advice from the Museum Assistants. Speaking to Bryn (a member of staff at St Fagans) was very insightful into the history. 

 

What did you enjoy about your experience? 

Everything! 

For example, I bought some bread from the bakery and my parents and brother were delighted.

For me I just felt more relaxed and that I’m at home here. I was introduced to lots of Museum Assistants, they were very interesting, chatty, friendly, and endearing. 

 

A big thank you to Harri for chatting to us about his time at St Fagans. He has now been successfully recruited as a pool staff member for the shop at St Fagans - so a big congratulations! 

 

Summary of an archaeology work placement, 2022-23

David Hughes (Student Work Placement), 13 November 2023

There is often some competition from people interested in archaeology to participate in Amgueddfa Cymru – Museum Wales’ student work placements, and I was delighted to secure a placement to help the museum assess and catalogue human remains. 

Joining a small group of individuals on placement, some of whom are students from Cardiff’s Archaeological Science course, we worked alongside the Curator to assess skeletons from the early medieval cemetery at Llandough, near Cardiff.  The excavations in the early 1990s produced in excess of a thousand skeletons, which have remained in Amgueddfa Cymru’s archive awaiting full examination. 

We learnt how the skeletons must be stored and handled in accordance with ethical standards for dealing with human remains.  Each skeleton is individually assessed for completeness, and sometimes it is possible to identify the sex and observe evidence of age and disease.  This information is recorded for entry into the Amgueddfa Cymru catalogue and will be useful in future research of human remains and the Llandough site, and contribute to the study of medieval archaeology more generally. 

Examining human remains provokes reflection on the lives of medieval people and, whilst it may not be for everyone, it does bring us closer to the past in a special way.  The work placement was an excellent learning experience.  The Curator, Adelle was very patient with all the questions raised by the student placements and generous in sharing her knowledge and skills.  It is a great way for Amgueddfa Cymru to engage with the public, and I am grateful for the opportunity to see behind the scenes and contribute to the work of the museum.  I hope Amgueddfa Cymru will continue to offer such opportunities for those who would like to get involved.
