Marine biology: Acidified oceans may corrode shark scales — Watts Up With That?

Prolonged exposure to high carbon dioxide (acidified) seawater may corrode tooth-like scales (denticles) covering the skin of puffadder shysharks, a study in Scientific Reports suggests. As ocean CO2 concentrations increase due to human activity, oceans are becoming more acidic, with potential implications for marine wildlife. Although the effects of acidified water have been studied in […]

Why Non-Academics Should Attend IMCC5

While I can’t make it to IMCC5 this June, opening up the conference to non-academics is a great idea and wish more marine science conferences offered the same opportunity

IMCC2018

Everyone loves the sea. Each year, millions of people all over the world flock to sandy beaches. When digging toes into the warm sand, listening to the waves crash over the ocean, how may people feel connected to the ocean? And how many people take that connection home with them, often far from the coast, and impossibly far from the open sea?

Our connection to the sea, no matter how far inland we may live, runs deep. Snow from the mountain tops melts, running off our roads and lawns into rivers, before eventually emptying out to the sea. With much of that run off comes pollutants, chemicals from our pesticides and sediment from agriculture. These pollutants threaten our health and fisheries, as cans of tuna line grocery store shelves.

The ocean has the power to transfix us; It lets us realize our deep connections to nature through…

How useful is twitter for academics, really?

Good post on how Twitter isn’t that effective in increasing readership of a journal article, though I think if a tweet does go viral, the conversion rate is bound to be lower than if 50 people actively engage with it. I would read at least the abstract of about %75 of the posts I retweet – otherwise, why bother retweeting it? To show an interest in the issue, that I can’t be bothered to read more about?
I think the author of the original tweet and journal paper is also important – if it’s an author you have previously read and liked (or an organisation that you actively support), surely it’s more likely to encourage the click-through than just, well, a ‘clickbait’ title?
Yep, maybe I’m deluded on that, which is why Buzzfeed and the like are so popular these days (21 Reasons Why Prawns Are Delicious) and true academic publication (The stochastic and comprehensively bland approach to garbage disposal literature) is not.

Recently I was intrigued by a post on twitter conversion rates (e.g. the likelihood that a view on your tweet results in a click on the link) by journalist Derek Thompson at the Atlantic. Derek writes that although using twitter gives him great joy, he’s not sure it results in the kinds of readership his employers would feel merits the time spent on the service. Derek found that even his most viral tweets only resulted in a conversion rate of about 3% – on par with the click-through rate of east asian display ads (i.e. quite poorly in the media world). Using the recently released twitter metrics, Derek found an average conversion of around 1.5% with the best posts hitting the 3% ceiling. Ultimately he concludes that twitter seems to be great at generating buzz within the twitter-sphere but performs poorly at translating that buzz into external influence.

This struck my curiosity…

Sunshine Coast Summers

Girl and the Deep Blue Sea

Hello summer! Even though we have had some fab hot days for a few weeks now, it is officially the first day of summer, my favourite time of the year! Long days means lots of beach time and hopefully capturing some ocean magic. These photos were taken over last summer on the amazing Sunshine Coast.

Playing around with communication

Different forms of science communication interest me – some companies I have worked for think it starts and ends with written work. But Sarah is right here – especially when catering to the younger generation (i.e. younger than my age of 39), conveying messages with long-form video, GIFs, Vines and tweets can be much more effective than 300 words in a barely-read article.

Science for Life. 365

Sarah: Most of the time, I write about science.

But I also like to dabble in other bits and pieces as well.

For example, recently I’ve written about fashion, long distance running and twitcher tourism.

From a broader perspective, I’ve also been playing around with making micro-movies using Vine and Vinyet.

In the kitchen I’ve shown the process of putting together an omelette, making moustache biscuits and constructing an easy ice-cream cake.

At the South Australian Museum I’ve recorded a giant squid and compiled skeletons. At the Adelaide Zoo, I captured a panda…ACTUALLY MOVING.

With just a few minutes planning, you can easily use these tools to share your experiences and even tell stories. Each time I capture footage, I perform a very quick analysis of the following points:

  • Visual appeal: what’s going to make this look good?
  • Structure: what’s the beginning, middle and end…

Seabirds are eating plastic litter in our oceans – but not only where you’d expect

Microplastic consumption by creatures above and below the water is my real concern. My uni colleagues and I produced a video on microplastics for a third year class and it brought home the ongoing problems when zooplankton are consuming microbeads and passing them up the food chain. If a blue whale eats up to 40 million krill per day, what percentage will contain plastics and what is the bioaccumulation in that top predator? Scary stuff

Filling the Gaps of Australia’s Commonwealth Marine Reserve System

There’s more confrontations expected between recreational/commercial fishers, government MPA planners and conservationists over the issue of marine parks. A lot of the spearfishing sites and Facebook groups I follow have regular posts on the ‘unnecessary’ expansion of marine parks, citing either anecdotal evidence (i.e. author’s opinion) or at best, out-of-context quotes from academic papers. I’m proudly a keen spearfisher too but have no time for people in the sport who decry marine parks while displaying constant photos of their undersized or over the limit kills.
There needs to be more clear, science-based communication from the government on why marine parks are needed, how fishers, conservation groups and regular folk all benefit and also, where any marine parks have been placed in the wrong areas and need to be reassessed. Because the latter has and will continue to happen, and pretending it doesn’t only serves to strengthen the case of anti-marine park activists

Weekend Wanderings: Photos Along the Bay

Chitons

Some days, when I’m sitting at my work desk trying to understand another journal paper on water sensitivity (no it’s not a medical condition), I think back to the simple times way back in 2013 in my marine science classes when we discussed chitons, radulas and which phylum these amazing creatures fit into – have a guess without looking it up!

Dalton Koss HQ

Visitors to coastal shores often come across unusual looking animals hidden in rock crevices. Here at Dalton Koss HQ we strive to help make sense of these unusual sea creatures by sharing our marine knowledge.

Chitons are one of these more unusual finds that many coastal visitors find on the rocky shoreline. With the Ch pronounced as a k sound, chitons have a fossilised appearance due to their numerous armoured plates. In fact, some people call Chitons the armadillos of the ocean as they are able to curl up into a ball using their armoured plates as protection.

Slide1

The armoured plates grow from the head to the foot of their body providing protection and camouflage from predators, hence why this animal is also commonly known as the coat-of-mail. The actual animal grows and lives under these armoured plates and its body is not segmented like its armour.

Here are…
