In this interview series, we learn about the perspectives of the PhD students whose wide-ranging work contribute to the SEA2 Program and share what drives them in their research.

Underground sediments can serve as geological libraries that offer a glimpse into past environments such as bygone mangrove ecosystems and shorelines.

For one PhD student, in particular, this study into proxy indicators of sea levels in the last 10,000 years is a way of amalgamating his love of mangroves and recent interest in sea-level rise. Proxies are organic materials that can be carbon-dated to serve as age markers in paleo-climate science.

In this interview series, we learn about the perspectives of the PhD students whose wide-ranging work contribute to the SEA2 Program and share what drives them in their research.

The past sea levels of the Holocene period can be reconstructed via the use of paleo-proxies, including the use of mangrove sediments, which contain organic materials that can be carbon-dated and serve as age markers and one person working on such historical records is Christabel Tan, a second-year PhD student on Professor Benjamin Horton’s research team. 

Collecting sediment core data for her thesis at Pulau Ubin, she studies and analyses their contents to help fine-tune sea-level...

Pandemics & Natural Hazards is a special series for the EOS Blog which looks at the compounding impacts of coinciding disasters. This third commentary is a contribution from EOS’ Centre for Geohazard Observations.

The daily coverage of the novel coronavirus disease (COVID-19) in the media has given the public an insight into how the crisis has impacted the healthcare sector. We’ve seen footage of hospitals inundated with stricken patients, hospital staff begging for supplies, and the global race to find the medical holy grail of the moment – a COVID-19 vaccine.

But what about the other sectors of science that are not directly linked to the coronavirus? How are they coping with, even transforming in, this pandemic and the ensuing cross-border lockdowns?

Pandemics & Natural Hazards is a special series for the EOS Blog which looks at the compounding impacts of coinciding disasters. This second commentary is contributed by EOS Principal Investigator Professor Benjamin Horton.

The COVID-19 pandemic, which is sweeping the globe infecting 7.6 million and causing the death of 424,472 (as of 12 June 2020) has understandably superseded the issue that dominated the news, social media, political activity, business practice, and academic research for much of 2019 – the climate emergency.

But it is useful to consider, are these two issues related, do they both have the same underlying causes, and can the solutions be the same?

The novel coronavirus COVID-19 is believed to have originated at wildlife markets...

When the time came for us to choose a place to house the EOS Dynamic Earth Games, the answer was a clear and obvious one – the Science Centre Singapore (SCS).

SCS has an impressive 40-year record of making science fun and accessible to the public. They successfully reach out to and engage more than one million visitors annually.

We, at the Earth Observatory of Singapore (EOS), know just how capable the SCS team is. We have worked with them over the years on various projects and launches (e.g. “Earth: Our Untamed Planet” exhibit currently in SCS, and the film screening of EOS documentary The Ratu River). Most recently, we spent the past six months working closely with SCS and acclaimed Californian science museum, The Exploratorium, on a new earth science exhibition...

Did my last blog post about the Dynamic Earth Games (DEG) leave you hungry for more details about the games? Well, I hope to satisfy your curiosity in this second post.

The Earth Observatory of Singapore (EOS) collaborated with BOHO Interactive and the Science Centre Singapore to develop seven different games. These fall into three broad categories:

Volcanoes and Typhoons, Assessing Risk, and Evacuation.

Volcanoes and Typhoons

The Dynamic Earth Games explain the science behind natural hazards with a strong focus on geology and meteorology. While playing the games, you will learn some of the signs of an impending volcanic eruption and the tools that...

What makes up the exciting memories of my first interaction with science? I recall touching the slimy texture of snails, sniffing ammonia salt (also known as “smelly salt”), and making my sister’s hair stand with a balloon.

For me, science is a journey – a fun-filled adventure that satisfies our curiosity of the universe. Think about it. What makes us enjoy playing soccer, chess, or Candy Crush? Games are fun because they involve elements of competition with others, even ourselves, and some require us to cooperate with one or more people. This sense of competition and camaraderie are essentially what makes us enjoy playing games.

The Dynamic Earth Games, an Earth Observatory of Singapore (EOS) series of board games and card games about natural hazards, use these...

The Singapore Series on Sea-Level Rise, a special blog series by four Masters students from the University of Melbourne.

Our previous blog posts in the Singapore Series on Sea-Level Rise discussed the science behind sea-level rise, as well as the effects on Singapore as global temperatures increase and sea levels rise. If you have missed reading our first two blogs, you can find them here:

The Science of Sea-Level Rise: How Climate Change will Hurt Singapore

Why Your Chicken Rice Depends on Sea-Level Rise

These blog posts should make it clear that Singapore is...

The Singapore Series on Sea-Level Rise, a special blog series by four Masters students from the University of Melbourne.

Sea-level rise (SLR) will affect all Singaporeans whether that be the businessman, the factory worker, or the high school student. Everyone will be impacted from the effects of rising sea levels. 

As emphasised in our first post of this special blog series on climate change in Singapore, the rate and magnitude of sea-level rise are increasing. The impacts of this acceleration will affect all aspects of Singaporean life.

In this blog post, we will explore aspects of food and water security, and the prospects of Singaporeans becoming...

The Singapore Series on Sea-Level Rise, a special blog series by four Masters students from the University of Melbourne.

We know human-induced climate change is real. It is happening across the world because of rising concentrations of greenhouse gas emissions in the atmosphere.

Sometimes it is hard to know if the climate is changing if you are isolated from many of its effects. However, countless populations are already exposed to the impacts of climate change, which include: warming temperatures, changing rainfall, increased droughts and wildfires, decline in agricultural yield, more flooding, and many other consequences.

Although Singapore is not presently in a climate crisis, the effects are not far away. Other than extreme temperatures, one of...
